Testlet 1 Executive Summary Project Overview CGE is a global, diversified, upstream (exploration and production) oil and gas company headquartered in North America. CGE s three main operating areas are North America, Europe, and Southeast Asia. CGE also has a portfolio of international exploration opportunities. CGE began in North America as a small, upstream oil and gas company. Through acquisitions, CGE grew quickly and acquired companies globally. This led to a decentralized IT model, both from systems and personnel perspectives. CGE currently utilizes several Citrix technologies to provide application virtualization to a global end-user base spread across several continents. Its current IT model for application virtualization is based on regional locations; each region hosts its own Citrix environment to support its local end-user base. CGE is moving toward a global IT model in which the entire application and desktop virtualization environment will be hosted in three data centers, each with a highly available NetScaler pair. CGE would like to provide dedicated desktops to some end-user groups to alleviate past issues with applications and performance. In addition, an Internet upgrade project is underway to eliminate slow connections at all sites. This will improve latency and bandwidth issues throughout the environments. CGE engaged Citrix Consulting to determine whether best practices are being followed in its existing Citrix environments; to provide a design document for a new, consolidated Citrix environment; and to point out risks that should be resolved before moving to this new environment. This deliverable represents the output of the requirements gathering phase and will be used as an input during the architectural design phase of this engagement. Through interactive meetings, Citrix Consulting obtained information regarding CGE s existing Citrix XenApp environments and strategic goals. By reviewing this information, CGE can understand and methodically address those areas that represent the most profound risks, improve various facets of its current environments, and prepare for the future design phase of a consolidated environment. Project Goals During the course of the project, CGE and Citrix Consulting identified a number of project goals. The following summarizes these goals: Perform a detailed assessment of the Citrix components supporting the existing Citrix environments, which include XenApp 6.x, XenServer, and NetScaler Gateway. Review relevant peripheral components that support the existing Citrix environments (for example, Active Directory, storage, SQL, networking) to determine if each can support current production workloads and a new Citrix environment. Identify operational and environmental improvements to better account for the environments growth. Overview CGE has locations spread across three primary regions North America, Europe, and Southeast Asia with its primary headquarters located in Houston. Sub regions exist within each region, each with its own Citrix infrastructure. Once power and cooling upgrades are complee, Houston will be the primary datacenter and London will be the secondary datacenter. The following diagram details the locations and network connection types.

Business Layer Overview Since CGE expanded quickly through acquisitions, corporate IT left infrastructure management up to the acquired companies. As a result, some regions have wellrun Citrix environments, while others experience critical outages that simultaneously affect hundreds of end users. CGE s CIO, who has been with CGE for slightly less than a year, was hired to be the central point for IT across all regions. The CIO has engaged with the various business units to understand their processes and received various complaints about the stability of the existing Citrix infrastructures. The CIO feels that the majority of Citrix infrastructure issues are due to a lack of centralized control and common platforms. Some regions have older versions of XenApp, while some are more current. As CGE moves forward, the CIO plans to use a single vendor for the entire solution, and wants to ensure that the new infrastructure is virtualized and fault tolerant. End-User Layer Overview CGE has 10,350 employees, approximately 4,700 of which access the Citrix environments daily. Peak logon times are Monday through Friday, from 8:00 a.m. 10:00 a.m., based on local, regional time zones. Technicians and engineers are shift workers who rotate to accommodate a 24 hours a day, seven days a week schedule. End user distribution is as follows:

The majority of end users connect using CGE-owned HP laptop and desktop devices. Over 90 percent of these devices are Windows 7-based, as CGE is in the process of completing a Windows XP to Windows 7 migration. CGE has standardized all these devices on Citrix Online Plug-in for Windows12.1, and is in the process of testing Receiver for Windows 4.2. In the past, some end users have complained about slowness when typing, which may indicate issues with latency. CGE also allows end users to connect using non-corporate-owned devices. Many end users connect from personal computers and mobile devices such as Apple ipads and iphones. End users are instructed to download Citrix Receiver from either the Citrix website or the Android or Apple app stores. End users can be grouped into six separate categories: Executives/Management Regional upper- and mid-level management staff. Back Office End users that provide functions such as accounting, administration, human resources, and finance. Research End users focus mainly on discovering new energy fields and sources. Engineers End users who work with technicians in a senior lead role for both technical and management functions. There is approximately one engineer for every five technicians. Technicians Field workers who service the oil and gas equipment. Sales Primary customer-facing group. End-user groups and numbers are as follows:

The engineers, technicians, and research groups access Citrix applications primarily in an office-type environment, but may need to access these applications while in the gas and oil fields. In these scenarios, end users connect to Citrix using local Internet connections, ranging from a wireless access point to a tethered mobile device. To prevent printer driver issues and sprawl, CGE tries to limit end users to their default printer when accessing Citrix. The IT department at CGE s headquarters has mandated that only the Citrix Universal Print Driver be utilized. As each region manages its own Citrix infrastructure, this has been difficult to enforce. Each end user s home directory is mapped when accessing a Citrix session; the drive-mapping letter varies based on the end user s region. End-user data is stored on different network device types and shares ranging from a Windows CIFS share to an NAS appliance. Corporate IT is unsure if end-user data is being backed up in all regions. CGE hopes to implement formal, corporate-wide standards in the new Citrix environment. Access Layer Overview Since each region has its own Citrix environment, end users are fairly isolated within their specific regions. In each region, NetScaler Gateway and Web Interface provide access for internal and external end users. In some regions, Citrix Secure Gateway is still being utilized for external access. This is primarily due to a past budget constraint, but CGE hopes to provide a redundant and fault-tolerant Citrix access solution for all regions with the new environment. Confusion with the use of the appropriate URL also occurs for end users travelling among regions. A common access point that routes end users to their closest datacenter would most

likely reduce this confusion. As CGE is sensitive to the research that is being conducted toward the development of new energy types and methods, external access to the Citrix environment must be as secure as possible. Currently, internal and external end users employ single-factor authentication; however, the development of a two-factor authentication process is desired. Access Controllers Overview The following table outlines the utilization of Web Interface, StoreFront, NetScaler Gateway, and Citrix Secure Gateway in the various Citrix environments. Resource Layer Personalization Overview The following table outlines the current overall profile strategy:

Corporate IT would like to streamline the profile management solution. Numerous end users complain about slow logon and logoff times, and routine profile corruption is also a concern. It is common for IT to have to reset end-user profiles on a daily basis. CGE hopes to provide a stable end-user profile platform by implementing a standardized set of hardware to host profiles and by employing Citrix Profile Management. Citrix policies vary from region to region, but corporate IT has tried to enforce the following policy settings (at a minimum): Technicians and engineers require USB mapping for various field devices such as flow meters and sonar devices. Since the majority of the remaining end-user groups probably do not need USB mapping, this could be disabled for those groups in the new environment. Corporate IT feels that most end users require only their default printer within a Citrix session. However, other end-user groups (primarily Back Office) need to access multiple printers with advanced printing functionality, such as stapling. In all cases, the need to limit native print drivers is critical. Applications Overview The majority of end users utilize published applications delivered through one of the regional XenApp farms. Some end-user groups require a full desktop instead of published applications. CGE mandates that no new software (agents) may be deployed in the current desktop infrastructure.

The following table provides additional details about the applications and desktops used throughout the Citrix environments.

Image Design Overview The following table outlines current application specifics. All servers are Windows 2008 R2 running XenApp 6.5, and all are virtual machines. Applications are delivered based on grouping. For example, Office Suite is installed on a dedicated set of servers.

Control Layer Infrastructure Services Active Directory As the solution integrates with Active Directory, resources must be easy to manage and maintain within the directory structure. The following details CGE s typical organizational unit (OU) structure for the XenApp environments. Overview

Databases Overview

CGE manages seven XenApp 6.5 farms one for each region. A variety of SQL server versions host the farm databases. Some databases are located on a shared SQL cluster, while others are standalone. The following table provides an overview of each environment, the database location, and the database configuration. Licensing Overview As each region currently manages its own Citrix infrastructure, licensing types vary from region to region. Some regions have more licenses than end users, while others sometimes reach their limit. Each region has its own Citrix and Microsoft license servers. Corporate IT will be consolidating the Citrix and Microsoft licenses under a common corporate agreement in the new Citrix environment. This will allow for better cost control and appropriate distribution of licenses. If needed, additional licenses will be procured to support the new Citrix solution. This may involve purchasing additional Microsoft and Citrix licenses to support a disaster recovery model. The following details the current Citrix and Microsoft license types.

XenApp Controllers Overview All regions use virtualized XenApp 6.5 servers. Some regions currently use Provisioning Services 6.1, but CGE wants to simplify management processes by moving to Provisioning Services 7.6 in each region. Although there are no test farms in the current Citrix environments, CGE would like to incorporate dedicated test environments in the new Citrix solution. These new test environments should utilize a minimum of storage. The following table details the XenApp environments for each region.

End users in some regions often complain about slow application enumeration and launch issues. Corporate IT hopes that these issues will be resolved with the new Citrix solution.

Hardware Layer Storage Overview Depending on the region, the physical hosts that provide hardware virtualization use a variety of local and SAN-based storage. Using local storage has prevented virtual machines from moving to another host in the event of a host failure, creating some regional capacity issues. Corporate IT is unsure if end-user data is being backed up in all regions. CGE hopes to implement global formal standards in the new Citrix environment. A fault-tolerant solution is required for hardware virtualization and end-user data storage. The following table describes the different storage types based on region: Networking Overview CGE utilizes regional private networks. Not all regions connect directly to each other. The network links range in size from 5 Mbps to 10 Mbps. The networks are congested at times among regions, causing large file copies to be scheduled during off hours to minimize disruption. CGE currently has a project underway to increase the bandwidth among regions and reduce latency for the new Citrix environment. The following diagram details the links among the regions.

Each region has a separate Internet connection of varying capacity and utilizes its own local network connection for Internet traffic. Microsoft and routing policies are in place to direct Internet-bound traffic to use this local Internet connection. The goal was to reduce the amount traffic on the links among regions, saving bandwidth for interregional traffic. For external Citrix access, each region uses its local Internet connection. The NetScaler Gateways and Citrix Secure Gateways are placed in a demilitarized zone (DMZ). Appropriate firewall ports are configured to allow the Citrix traffic to navigate to the internal resources. Control Hosts Overview As CGE acquired several companies within a short period of time, it did not change any of the acquired companies infrastructures. This has resulted in regional inconsistency in hypervisor platforms and versions and with hardware vendors. Corporate IT hopes to streamline the infrastructure to ensure corporate standards are followed. At a minimum, a standard hypervisor platform must be used to allow IT resources to train on a common hypervisor platform and to quickly assist in other regions when needed. For the new Citrix solution, CGE has budgeted for the replacement of aging infrastructure equipment, where needed, including the hypervisor platform. Procurement of the best infrastructure components within this planned budget must be ensured. Operations Layer Support Overview In the current configuration, each region is responsible for supporting its end users and infrastructure. This often leads to confusion for end users who travel, as

well as the for the help desk members who work with these end users. Corporate IT hopes to develop a centralized support structure from the end-user layer to the infrastructure layer. The CIO envisions a model that allows an end user to call one number for support. Regional staff will support the help desk 24 hours a day, seven days a week. If first-tier help desk support is unable to resolve the issue in a timely manner, a second-tier support team would be engaged. In order to facilitate this troubleshooting model, the first-tier help desk and second-tier support teams would require access to the Citrix infrastructure. The CIO would prefer a centralized console for the help desk team, but it is not a requirement. In the past, some regions had training budgets, while others did not. This has often resulted in lengthy resolution of issues due to improper training. To alleviate this, the CIO has mandated that the first-tier help desk and second-tier support teams be properly trained in the products being implemented in the new Citrix solution. Testing and Change Control Overview An analysis revealed that none of the regions have a proper test environment. At best, some regions have a few test XenApp servers in their production farms that are used for testing. In addition, the procedures for implementing changes to the systems vary from region to region. Some regions have a documented change control process, while others install changes as application owners or end users request them. This has resulted in overall poor performance of the Citrix environments and has caused outages in some regions. The CIO has mandated that in the new Citrix solution, a change control board must approve changes, and a separate test environment must be deployed. Operations Overview Citrix Rollups and hotfixes are applied sporadically throughout the Citrix farms. The following table details the implementation of Citrix Rollups. Backups of the Aberdeen, Houston, and London SQL databases are conducted daily via SQL. A nightly backup of the Windows server ensures that the local SQL backup is captured. However, the restoration process has not been tested. The remaining locations lack SQL administrators, so it is unclear if SQL backups are being performed. The CIO recognizes this gap and is taking steps to ensure that all Citrix databases are routinely backed up. For the short term, the SQL administrators in the Houston location will assume responsibility for the SQL backups in the locations that lack SQL administrators.

Since each region has operated independently, no central disaster recovery plan exists. Corporate IT hopes to provide a seamless disaster recovery solution for all locations and believes that it may be possible to utilize regional resources with minimal overhead. Corporate IT feels that it is likely that, in the event of a disaster, only a subset of a region s end users would require a disaster recovery solution, and believes that approximately 50 percent of regional end users would be a good starting point. Monitoring Overview The Houston location is the only location using EdgeSight. Corporate IT uses EdgeSight for license trending and occasional end-user troubleshooting. Interviews with the IT staff using EdgeSight revealed that EdgeSight could probably be better utilized. The help desk staff has tried using EdgeSight, but has felt overwhelmed and would prefer a much simpler interface to troubleshoot end-user issues. CGE recently purchased Tivoli, an antivirus program, and is in the process of rolling it out to all locations. Corporate IT has requested from Citrix Consulting any specific monitoring metrics and alerts related to the Citrix environment. CGE realizes that effective monitoring will allow them to be proactive in addressing issues before they cause critical outages. The following is CGE s current antivirus policy: Periodic scanning of servers must be conducted at 1:00 a.m., local time, each morning. All workstations and servers must have antivirus software installed, and real-time scanning must be enabled. Periodic updating of antivirus software is required. Currently, antivirus updates are automatically delivered at 8:00 a.m., 1:00 p.m., 4:00 p.m., and 11:00 p.m., local time. Only vendor-required exclusions may be used, and all exclusions must be configured for both real-time and periodic scans. Real-time antivirus scanning must be configured to scan files when they are accessed and written. All servers must be configured to scan their local drives, and all remote network drive scanning must be disabled. Corporate IT has shared several Citrix articles relating to Citrix product antivirus exclusions with the regions. It is unclear if the regions have implemented these exclusions. Executive Summary Project Overview: Project Overview CGE is a global, diversified, upstream (exploration and production) oil and gas company headquartered in North America. CGE s three main operating areas are North America, Europe, and Southeast Asia. CGE also has a portfolio of international exploration opportunities.

Some databases are located on a shared SQL cluster, while others are standalone. The following table provides an overview of each environment, the database location, and the database configuration. Licensing Overview As each region currently manages its own Citrix infrastructure, licensing types vary from region to region. Some regions have more licenses than end users, while others sometimes reach their limit. Each region has its own Citrix and Microsoft license servers. Corporate IT will be consolidating the Citrix and Microsoft licenses under a common corporate agreement in the new Citrix environment. This will allow for better cost control and appropriate distribution of licenses. If needed, additional licenses will be procured to support the new Citrix solution. This may involve purchasing additional Microsoft and Citrix licenses to support a disaster recovery model. The following details the current Citrix and Microsoft license types.

XenApp Controllers Overview All regions use virtualized XenApp 6.5 servers. Some regions currently use Provisioning Services 6.1, but CGE wants to simplify management processes by moving to Provisioning Services 7.6 in each region. Although there are no test farms in the current Citrix environments, CGE would like to incorporate dedicated test environments in the new Citrix solution. These new test environments should utilize a minimum of storage. The following table details the XenApp environments for each region.

End users in some regions often complain about slow application enumeration and launch issues. Corporate IT hopes that these issues will be resolved with the new Citrix solution.

Hardware Layer: Hardware Layer Storage Overview Depending on the region, the physical hosts that provide hardware virtualization use a variety of local and SAN-based storage. Using local storage has prevented virtual machines from moving to another host in the event of a host failure, creating some regional capacity issues. Corporate IT is unsure if end-user data is being backed up in all regions. CGE hopes to implement global formal standards in the new Citrix environment. A fault-tolerant solution is required for hardware virtualization and end-user data storage. The following table describes the different storage types based on region: Networking Overview CGE utilizes regional private networks. Not all regions connect directly to each other. The network links range in size from 5 Mbps to 10 Mbps. The networks are congested at times among regions, causing large file copies to be scheduled during off hours to minimize disruption. CGE currently has a project underway to increase the bandwidth among regions and reduce latency for the new Citrix environment. The following diagram details the links among the regions.

Each region has a separate Internet connection of varying capacity and utilizes its own local network connection for Internet traffic. Microsoft and routing policies are in place to direct Internet-bound traffic to use this local Internet connection. The goal was to reduce the amount traffic on the links among regions, saving bandwidth for interregional traffic. For external Citrix access, each region uses its local Internet connection. The NetScaler Gateways and Citrix Secure Gateways are placed in a demilitarized zone (DMZ). Appropriate firewall ports are configured to allow the Citrix traffic to navigate to the internal resources. Control Hosts Overview As CGE acquired several companies within a short period of time, it did not change any of the acquired companies infrastructures. This has resulted in regional inconsistency in hypervisor platforms and versions and with hardware vendors. Corporate IT hopes to streamline the infrastructure to ensure corporate standards are followed. At a minimum, a standard hypervisor platform must be used to allow IT resources to train on a common hypervisor platform and to quickly assist in other regions when needed. For the new Citrix solution, CGE has budgeted for the replacement of aging infrastructure equipment, where needed, including the hypervisor platform. Procurement of the best infrastructure components within this planned budget must be ensured. Operations Layer: Operations Layer Support Overview

In the current configuration, each region is responsible for supporting its end users and infrastructure. This often leads to confusion for end users who travel, as well as the for the help desk members who work with these end users. Corporate IT hopes to develop a centralized support structure from the end-user layer to the infrastructure layer. The CIO envisions a model that allows an end user to call one number for support. Regional staff will support the help desk 24 hours a day, seven days a week. If first-tier help desk support is unable to resolve the issue in a timely manner, a second-tier support team would be engaged. In order to facilitate this troubleshooting model, the first-tier help desk and second-tier support teams would require access to the Citrix infrastructure. The CIO would prefer a centralized console for the help desk team, but it is not a requirement. In the past, some regions had training budgets, while others did not. This has often resulted in lengthy resolution of issues due to improper training. To alleviate this, the CIO has mandated that the first-tier help desk and second-tier support teams be properly trained in the products being implemented in the new Citrix solution. Testing and Change Control Overview An analysis revealed that none of the regions have a proper test environment. At best, some regions have a few test XenApp servers in their production farms that are used for testing. In addition, the procedures for implementing changes to the systems vary from region to region. Some regions have a documented change control process, while others install changes as application owners or end users request them. This has resulted in overall poor performance of the Citrix environments and has caused outages in some regions. The CIO has mandated that in the new Citrix solution, a change control board must approve changes, and a separate test environment must be deployed. Operations Overview Citrix Rollups and hotfixes are applied sporadically throughout the Citrix farms. The following table details the implementation of Citrix Rollups. Backups of the Aberdeen, Houston, and London SQL databases are conducted daily via SQL. A nightly backup of the Windows server ensures that the local SQL backup is captured. However, the restoration process has not been tested. The remaining locations lack SQL administrators, so it is unclear if SQL backups are being performed. The CIO recognizes this gap and is taking steps to ensure that all Citrix databases are routinely backed up. For the short term, the SQL administrators in the

Houston location will assume responsibility for the SQL backups in the locations that lack SQL administrators. Since each region has operated independently, no central disaster recovery plan exists. Corporate IT hopes to provide a seamless disaster recovery solution for all locations and believes that it may be possible to utilize regional resources with minimal overhead. Corporate IT feels that it is likely that, in the event of a disaster, only a subset of a region s end users would require a disaster recovery solution, and believes that approximately 50 percent of regional end users would be a good starting point. Monitoring Overview The Houston location is the only location using EdgeSight. Corporate IT uses EdgeSight for license trending and occasional end-user troubleshooting. Interviews with the IT staff using EdgeSight revealed that EdgeSight could probably be better utilized. The help desk staff has tried using EdgeSight, but has felt overwhelmed and would prefer a much simpler interface to troubleshoot end-user issues. CGE recently purchased Tivoli, an antivirus program, and is in the process of rolling it out to all locations. Corporate IT has requested from Citrix Consulting any specific monitoring metrics and alerts related to the Citrix environment. CGE realizes that effective monitoring will allow them to be proactive in addressing issues before they cause critical outages. The following is CGE s current antivirus policy: Periodic scanning of servers must be conducted at 1:00 a.m., local time, each morning. All workstations and servers must have antivirus software installed, and real-time scanning must be enabled. Periodic updating of antivirus software is required. Currently, antivirus updates are automatically delivered at 8:00 a.m., 1:00 p.m., 4:00 p.m., and 11:00 p.m., local time. Only vendor-required exclusions may be used, and all exclusions must be configured for both real-time and periodic scans. Real-time antivirus scanning must be configured to scan files when they are accessed and written. All servers must be configured to scan their local drives, and all remote network drive scanning must be disabled. Corporate IT has shared several Citrix articles relating to Citrix product antivirus exclusions with the regions. It is unclear if the regions have implemented these exclusions.

Testlet 1 Executive Summary Project Overview CGE is a global, diversified, upstream (exploration and production) oil and gas company headquartered in North America. CGE s three main operating areas are North America, Europe, and Southeast Asia. CGE also has a portfolio of international exploration opportunities. CGE began in North America as a small, upstream oil and gas company. Through acquisitions, CGE grew quickly and acquired companies globally. This led to a decentralized IT model, both from systems and personnel perspectives. CGE currently utilizes several Citrix technologies to provide application virtualization to a global end-user base spread across several continents. Its current IT model for application virtualization is based on regional locations; each region hosts its own Citrix environment to support its local end-user base. CGE is moving toward a global IT model in which the entire application and desktop virtualization environment will be hosted in three data centers, each with a highly available NetScaler pair. CGE would like to provide dedicated desktops to some end-user groups to alleviate past issues with applications and performance. In addition, an Internet upgrade project is underway to eliminate slow connections at all sites. This will improve latency and bandwidth issues throughout the environments. CGE engaged Citrix Consulting to determine whether best practices are being followed in its existing Citrix environments; to provide a design document for a new, consolidated Citrix environment; and to point out risks that should be resolved before moving to this new environment. This deliverable represents the output of the requirements gathering phase and will be used as an input during the architectural design phase of this engagement. Through interactive meetings, Citrix Consulting obtained information regarding CGE s existing Citrix XenApp environments and strategic goals. By reviewing this information, CGE can understand and methodically address those areas that represent the most profound risks, improve various facets of its current environments, and prepare for the future design phase of a consolidated environment. Project Goals During the course of the project, CGE and Citrix Consulting identified a number of project goals. The following summarizes these goals: Perform a detailed assessment of the Citrix components supporting the existing Citrix environments, which include XenApp 6.x, XenServer, and NetScaler Gateway. Review relevant peripheral components that support the existing Citrix environments (for example, Active Directory, storage, SQL, networking) to determine if each can support current production workloads and a new Citrix environment. Identify operational and environmental improvements to better account for the environments growth. Overview CGE has locations spread across three primary regions North America, Europe, and Southeast Asia with its primary headquarters located in Houston. Sub regions exist within each region, each with its own Citrix infrastructure. Once power and cooling upgrades are complee, Houston will be the primary datacenter and London will be the secondary datacenter. The following diagram details the locations and network connection types.

Business Layer Overview Since CGE expanded quickly through acquisitions, corporate IT left infrastructure management up to the acquired companies. As a result, some regions have wellrun Citrix environments, while others experience critical outages that simultaneously affect hundreds of end users. CGE s CIO, who has been with CGE for slightly less than a year, was hired to be the central point for IT across all regions. The CIO has engaged with the various business units to understand their processes and received various complaints about the stability of the existing Citrix infrastructures. The CIO feels that the majority of Citrix infrastructure issues are due to a lack of centralized control and common platforms. Some regions have older versions of XenApp, while some are more current. As CGE moves forward, the CIO plans to use a single vendor for the entire solution, and wants to ensure that the new infrastructure is virtualized and fault tolerant. End-User Layer Overview CGE has 10,350 employees, approximately 4,700 of which access the Citrix environments daily. Peak logon times are Monday through Friday, from 8:00 a.m. 10:00 a.m., based on local, regional time zones. Technicians and engineers are shift workers who rotate to accommodate a 24 hours a day, seven days a week schedule. End user distribution is as follows:

The majority of end users connect using CGE-owned HP laptop and desktop devices. Over 90 percent of these devices are Windows 7-based, as CGE is in the process of completing a Windows XP to Windows 7 migration. CGE has standardized all these devices on Citrix Online Plug-in for Windows12.1, and is in the process of testing Receiver for Windows 4.2. In the past, some end users have complained about slowness when typing, which may indicate issues with latency. CGE also allows end users to connect using non-corporate-owned devices. Many end users connect from personal computers and mobile devices such as Apple ipads and iphones. End users are instructed to download Citrix Receiver from either the Citrix website or the Android or Apple app stores. End users can be grouped into six separate categories: Executives/Management Regional upper- and mid-level management staff. Back Office End users that provide functions such as accounting, administration, human resources, and finance. Research End users focus mainly on discovering new energy fields and sources. Engineers End users who work with technicians in a senior lead role for both technical and management functions. There is approximately one engineer for every five technicians. Technicians Field workers who service the oil and gas equipment. Sales Primary customer-facing group. End-user groups and numbers are as follows:

The engineers, technicians, and research groups access Citrix applications primarily in an office-type environment, but may need to access these applications while in the gas and oil fields. In these scenarios, end users connect to Citrix using local Internet connections, ranging from a wireless access point to a tethered mobile device. To prevent printer driver issues and sprawl, CGE tries to limit end users to their default printer when accessing Citrix. The IT department at CGE s headquarters has mandated that only the Citrix Universal Print Driver be utilized. As each region manages its own Citrix infrastructure, this has been difficult to enforce. Each end user s home directory is mapped when accessing a Citrix session; the drive-mapping letter varies based on the end user s region. End-user data is stored on different network device types and shares ranging from a Windows CIFS share to an NAS appliance. Corporate IT is unsure if end-user data is being backed up in all regions. CGE hopes to implement formal, corporate-wide standards in the new Citrix environment. Access Layer Overview Since each region has its own Citrix environment, end users are fairly isolated within their specific regions. In each region, NetScaler Gateway and Web Interface provide access for internal and external end users. In some regions, Citrix Secure Gateway is still being utilized for external access. This is primarily due to a past budget constraint, but CGE hopes to provide a redundant and fault-tolerant Citrix access solution for all regions with the new environment. Confusion with the use of the appropriate URL also occurs for end users travelling among regions. A common access point that routes end users to their closest datacenter would most

likely reduce this confusion. As CGE is sensitive to the research that is being conducted toward the development of new energy types and methods, external access to the Citrix environment must be as secure as possible. Currently, internal and external end users employ single-factor authentication; however, the development of a two-factor authentication process is desired. Access Controllers Overview The following table outlines the utilization of Web Interface, StoreFront, NetScaler Gateway, and Citrix Secure Gateway in the various Citrix environments. Resource Layer Personalization Overview The following table outlines the current overall profile strategy:

Corporate IT would like to streamline the profile management solution. Numerous end users complain about slow logon and logoff times, and routine profile corruption is also a concern. It is common for IT to have to reset end-user profiles on a daily basis. CGE hopes to provide a stable end-user profile platform by implementing a standardized set of hardware to host profiles and by employing Citrix Profile Management. Citrix policies vary from region to region, but corporate IT has tried to enforce the following policy settings (at a minimum): Technicians and engineers require USB mapping for various field devices such as flow meters and sonar devices. Since the majority of the remaining end-user groups probably do not need USB mapping, this could be disabled for those groups in the new environment. Corporate IT feels that most end users require only their default printer within a Citrix session. However, other end-user groups (primarily Back Office) need to access multiple printers with advanced printing functionality, such as stapling. In all cases, the need to limit native print drivers is critical. Applications Overview The majority of end users utilize published applications delivered through one of the regional XenApp farms. Some end-user groups require a full desktop instead of published applications. CGE mandates that no new software (agents) may be deployed in the current desktop infrastructure.

The following table provides additional details about the applications and desktops used throughout the Citrix environments.

Image Design Overview The following table outlines current application specifics. All servers are Windows 2008 R2 running XenApp 6.5, and all are virtual machines. Applications are delivered based on grouping. For example, Office Suite is installed on a dedicated set of servers.

Control Layer Infrastructure Services Active Directory As the solution integrates with Active Directory, resources must be easy to manage and maintain within the directory structure. The following details CGE s typical organizational unit (OU) structure for the XenApp environments. Overview

Databases Overview

CGE manages seven XenApp 6.5 farms one for each region. A variety of SQL server versions host the farm databases. Some databases are located on a shared SQL cluster, while others are standalone. The following table provides an overview of each environment, the database location, and the database configuration. Licensing Overview As each region currently manages its own Citrix infrastructure, licensing types vary from region to region. Some regions have more licenses than end users, while others sometimes reach their limit. Each region has its own Citrix and Microsoft license servers. Corporate IT will be consolidating the Citrix and Microsoft licenses under a common corporate agreement in the new Citrix environment. This will allow for better cost control and appropriate distribution of licenses. If needed, additional licenses will be procured to support the new Citrix solution. This may involve purchasing additional Microsoft and Citrix licenses to support a disaster recovery model. The following details the current Citrix and Microsoft license types.

XenApp Controllers Overview All regions use virtualized XenApp 6.5 servers. Some regions currently use Provisioning Services 6.1, but CGE wants to simplify management processes by moving to Provisioning Services 7.6 in each region. Although there are no test farms in the current Citrix environments, CGE would like to incorporate dedicated test environments in the new Citrix solution. These new test environments should utilize a minimum of storage. The following table details the XenApp environments for each region.

End users in some regions often complain about slow application enumeration and launch issues. Corporate IT hopes that these issues will be resolved with the new Citrix solution.

Hardware Layer Storage Overview Depending on the region, the physical hosts that provide hardware virtualization use a variety of local and SAN-based storage. Using local storage has prevented virtual machines from moving to another host in the event of a host failure, creating some regional capacity issues. Corporate IT is unsure if end-user data is being backed up in all regions. CGE hopes to implement global formal standards in the new Citrix environment. A fault-tolerant solution is required for hardware virtualization and end-user data storage. The following table describes the different storage types based on region: Networking Overview CGE utilizes regional private networks. Not all regions connect directly to each other. The network links range in size from 5 Mbps to 10 Mbps. The networks are congested at times among regions, causing large file copies to be scheduled during off hours to minimize disruption. CGE currently has a project underway to increase the bandwidth among regions and reduce latency for the new Citrix environment. The following diagram details the links among the regions.

Each region has a separate Internet connection of varying capacity and utilizes its own local network connection for Internet traffic. Microsoft and routing policies are in place to direct Internet-bound traffic to use this local Internet connection. The goal was to reduce the amount traffic on the links among regions, saving bandwidth for interregional traffic. For external Citrix access, each region uses its local Internet connection. The NetScaler Gateways and Citrix Secure Gateways are placed in a demilitarized zone (DMZ). Appropriate firewall ports are configured to allow the Citrix traffic to navigate to the internal resources. Control Hosts Overview As CGE acquired several companies within a short period of time, it did not change any of the acquired companies infrastructures. This has resulted in regional inconsistency in hypervisor platforms and versions and with hardware vendors. Corporate IT hopes to streamline the infrastructure to ensure corporate standards are followed. At a minimum, a standard hypervisor platform must be used to allow IT resources to train on a common hypervisor platform and to quickly assist in other regions when needed. For the new Citrix solution, CGE has budgeted for the replacement of aging infrastructure equipment, where needed, including the hypervisor platform. Procurement of the best infrastructure components within this planned budget must be ensured. Operations Layer Support Overview In the current configuration, each region is responsible for supporting its end users and infrastructure. This often leads to confusion for end users who travel, as

well as the for the help desk members who work with these end users. Corporate IT hopes to develop a centralized support structure from the end-user layer to the infrastructure layer. The CIO envisions a model that allows an end user to call one number for support. Regional staff will support the help desk 24 hours a day, seven days a week. If first-tier help desk support is unable to resolve the issue in a timely manner, a second-tier support team would be engaged.

This has often resulted in lengthy resolution of issues due to improper training. To alleviate this, the CIO has mandated that the first-tier help desk and second-tier support teams be properly trained in the products being implemented in the new Citrix solution. Testing and Change Control Overview An analysis revealed that none of the regions have a proper test environment. At best, some regions have a few test XenApp servers in their production farms that are used for testing. In addition, the procedures for implementing changes to the systems vary from region to region. Some regions have a documented change control process, while others install changes as application owners or end users request them. This has resulted in overall poor performance of the Citrix environments and has caused outages in some regions. The CIO has mandated that in the new Citrix solution, a change control board must approve changes, and a separate test environment must be deployed. Operations Overview Citrix Rollups and hotfixes are applied sporadically throughout the Citrix farms. The following table details the implementation of Citrix Rollups. Backups of the Aberdeen, Houston, and London SQL databases are conducted daily via SQL. A nightly backup of the Windows server ensures that the local SQL backup is captured. However, the restoration process has not been tested. The remaining locations lack SQL administrators, so it is unclear if SQL backups are being performed. The CIO recognizes this gap and is taking steps to ensure that all Citrix databases are routinely backed up. For the short term, the SQL administrators in the Houston location will assume responsibility for the SQL backups in the locations that lack SQL administrators.

Since each region has operated independently, no central disaster recovery plan exists. Corporate IT hopes to provide a seamless disaster recovery solution for all locations and believes that it may be possible to utilize regional resources with minimal overhead. Corporate IT feels that it is likely that, in the event of a disaster, only a subset of a region s end users would require a disaster recovery solution, and believes that approximately 50 percent of regional end users would be a good starting point. Monitoring Overview The Houston location is the only location using EdgeSight. Corporate IT uses EdgeSight for license trending and occasional end-user troubleshooting. Interviews with the IT staff using EdgeSight revealed that EdgeSight could probably be better utilized. The help desk staff has tried using EdgeSight, but has felt overwhelmed and would prefer a much simpler interface to troubleshoot end-user issues. CGE recently purchased Tivoli, an antivirus program, and is in the process of rolling it out to all locations. Corporate IT has requested from Citrix Consulting any specific monitoring metrics and alerts related to the Citrix environment. CGE realizes that effective monitoring will allow them to be proactive in addressing issues before they cause critical outages. The following is CGE s current antivirus policy: Periodic scanning of servers must be conducted at 1:00 a.m., local time, each morning. All workstations and servers must have antivirus software installed, and real-time scanning must be enabled. Periodic updating of antivirus software is required. Currently, antivirus updates are automatically delivered at 8:00 a.m., 1:00 p.m., 4:00 p.m., and 11:00 p.m., local time. Only vendor-required exclusions may be used, and all exclusions must be configured for both real-time and periodic scans. Real-time antivirus scanning must be configured to scan files when they are accessed and written. All servers must be configured to scan their local drives, and all remote network drive scanning must be disabled. Corporate IT has shared several Citrix articles relating to Citrix product antivirus exclusions with the regions. It is unclear if the regions have implemented these exclusions.

In the past, some end users have complained about slowness when typing, which may indicate issues with latency. CGE also allows end users to connect using non-corporate-owned devices. Many end users connect from personal computers and mobile devices such as Apple ipads and iphones. End users are instructed to download Citrix Receiver from either the Citrix website or the Android or Apple app stores. End users can be grouped into six separate categories: Executives/Management Regional upper- and mid-level management staff. Back Office End users that provide functions such as accounting, administration, human resources, and finance. Research End users focus mainly on discovering new energy fields and sources. Engineers End users who work with technicians in a senior lead role for both technical and management functions. There is approximately one engineer for every five technicians. Technicians Field workers who service the oil and gas equipment. Sales Primary customer-facing group. End-user groups and numbers are as follows:

The engineers, technicians, and research groups access Citrix applications primarily in an office-type environment, but may need to access these applications while in the gas and oil fields. In these scenarios, end users connect to Citrix using local Internet connections, ranging from a wireless access point to a tethered mobile device. To prevent printer driver issues and sprawl, CGE tries to limit end users to their default printer when accessing Citrix. The IT department at CGE s headquarters has mandated that only the Citrix Universal Print Driver be utilized. As each region manages its own Citrix infrastructure, this has been difficult to enforce. Each end user s home directory is mapped when accessing a Citrix session; the drive-mapping letter varies based on the end user s region. End-user data is stored on different network device types and shares ranging from a Windows CIFS share to an NAS appliance. Corporate IT is unsure if end-user data is being backed up in all regions. CGE hopes to implement formal, corporate-wide standards in the new Citrix environment. Access Layer Overview Since each region has its own Citrix environment, end users are fairly isolated within their specific regions. In each region, NetScaler Gateway and Web Interface provide access for internal and external end users. In some regions, Citrix Secure Gateway is still being utilized for external access. This is primarily due to a past budget constraint, but CGE hopes to provide a redundant and fault-tolerant Citrix access solution for all regions with the new environment. Confusion with the use of the appropriate URL also occurs for end users travelling among regions. A common access point that routes end users to their closest datacenter would most

likely reduce this confusion. As CGE is sensitive to the research that is being conducted toward the development of new energy types and methods, external access to the Citrix environment must be as secure as possible. Currently, internal and external end users employ single-factor authentication; however, the development of a two-factor authentication process is desired. Access Controllers Overview The following table outlines the utilization of Web Interface, StoreFront, NetScaler Gateway, and Citrix Secure Gateway in the various Citrix environments. Resource Layer Personalization Overview The following table outlines the current overall profile strategy:

Corporate IT would like to streamline the profile management solution. Numerous end users complain about slow logon and logoff times, and routine profile corruption is also a concern. It is common for IT to have to reset end-user profiles on a daily basis. CGE hopes to provide a stable end-user profile platform by implementing a standardized set of hardware to host profiles and by employing Citrix Profile Management. Citrix policies vary from region to region, but corporate IT has tried to enforce the following policy settings (at a minimum): Technicians and engineers require USB mapping for various field devices such as flow meters and sonar devices. Since the majority of the remaining end-user groups probably do not need USB mapping, this could be disabled for those groups in the new environment. Corporate IT feels that most end users require only their default printer within a Citrix session. However, other end-user groups (primarily Back Office) need to access multiple printers with advanced printing functionality, such as stapling. In all cases, the need to limit native print drivers is critical. Applications Overview The majority of end users utilize published applications delivered through one of the regional XenApp farms. Some end-user groups require a full desktop instead of published applications. CGE mandates that no new software (agents) may be deployed in the current desktop infrastructure.

The following table provides additional details about the applications and desktops used throughout the Citrix environments.

Image Design Overview The following table outlines current application specifics. All servers are Windows 2008 R2 running XenApp 6.5, and all are virtual machines. Applications are delivered based on grouping. For example, Office Suite is installed on a dedicated set of servers.

Control Layer Infrastructure Services Active Directory As the solution integrates with Active Directory, resources must be easy to manage and maintain within the directory structure. The following details CGE s typical organizational unit (OU) structure for the XenApp environments. Overview

Databases Overview

CGE manages seven XenApp 6.5 farms one for each region. A variety of SQL server versions host the farm databases. Some databases are located on a shared SQL cluster, while others are standalone. The following table provides an overview of each environment, the database location, and the database configuration. Licensing Overview As each region currently manages its own Citrix infrastructure, licensing types vary from region to region. Some regions have more licenses than end users, while others sometimes reach their limit. Each region has its own Citrix and Microsoft license servers. Corporate IT will be consolidating the Citrix and Microsoft licenses under a common corporate agreement in the new Citrix environment. This will allow for better cost control and appropriate distribution of licenses. If needed, additional licenses will be procured to support the new Citrix solution. This may involve purchasing additional Microsoft and Citrix licenses to support a disaster recovery model. The following details the current Citrix and Microsoft license types.

XenApp Controllers Overview All regions use virtualized XenApp 6.5 servers. Some regions currently use Provisioning Services 6.1, but CGE wants to simplify management processes by moving to Provisioning Services 7.6 in each region. Although there are no test farms in the current Citrix environments, CGE would like to incorporate dedicated test environments in the new Citrix solution. These new test environments should utilize a minimum of storage. The following table details the XenApp environments for each region.

End users in some regions often complain about slow application enumeration and launch issues. Corporate IT hopes that these issues will be resolved with the new Citrix solution.

Hardware Layer Storage Overview Depending on the region, the physical hosts that provide hardware virtualization use a variety of local and SAN-based storage. Using local storage has prevented virtual machines from moving to another host in the event of a host failure, creating some regional capacity issues. Corporate IT is unsure if end-user data is being backed up in all regions. CGE hopes to implement global formal standards in the new Citrix environment. A fault-tolerant solution is required for hardware virtualization and end-user data storage. The following table describes the different storage types based on region: Networking Overview CGE utilizes regional private networks. Not all regions connect directly to each other. The network links range in size from 5 Mbps to 10 Mbps. The networks are congested at times among regions, causing large file copies to be scheduled during off hours to minimize disruption. CGE currently has a project underway to increase the bandwidth among regions and reduce latency for the new Citrix environment. The following diagram details the links among the regions.

Each region has a separate Internet connection of varying capacity and utilizes its own local network connection for Internet traffic. Microsoft and routing policies are in place to direct Internet-bound traffic to use this local Internet connection. The goal was to reduce the amount traffic on the links among regions, saving bandwidth for interregional traffic. For external Citrix access, each region uses its local Internet connection. The NetScaler Gateways and Citrix Secure Gateways are placed in a demilitarized zone (DMZ). Appropriate firewall ports are configured to allow the Citrix traffic to navigate to the internal resources. Control Hosts Overview As CGE acquired several companies within a short period of time, it did not change any of the acquired companies infrastructures. This has resulted in regional inconsistency in hypervisor platforms and versions and with hardware vendors. Corporate IT hopes to streamline the infrastructure to ensure corporate standards are followed. At a minimum, a standard hypervisor platform must be used to allow IT resources to train on a common hypervisor platform and to quickly assist in other regions when needed. For the new Citrix solution, CGE has budgeted for the replacement of aging infrastructure equipment, where needed, including the hypervisor platform. Procurement of the best infrastructure components within this planned budget must be ensured. Operations Layer Support Overview In the current configuration, each region is responsible for supporting its end users and infrastructure. This often leads to confusion for end users who travel, as

well as the for the help desk members who work with these end users. Corporate IT hopes to develop a centralized support structure from the end-user layer to the infrastructure layer. The CIO envisions a model that allows an end user to call one number for support. Regional staff will support the help desk 24 hours a day, seven days a week. If first-tier help desk support is unable to resolve the issue in a timely manner, a second-tier support team would be engaged. In order to facilitate this troubleshooting model, the first-tier help desk and second-tier support teams would require access to the Citrix infrastructure. The CIO would prefer a centralized console for the help desk team, but it is not a requirement. In the past, some regions had training budgets, while others did not. This has often resulted in lengthy resolution of issues due to improper training. To alleviate this, the CIO has mandated that the first-tier help desk and second-tier support teams be properly trained in the products being implemented in the new Citrix solution. Testing and Change Control Overview An analysis revealed that none of the regions have a proper test environment. At best, some regions have a few test XenApp servers in their production farms that are used for testing. In addition, the procedures for implementing changes to the systems vary from region to region. Some regions have a documented change control process, while others install changes as application owners or end users request them. This has resulted in overall poor performance of the Citrix environments and has caused outages in some regions. The CIO has mandated that in the new Citrix solution, a change control board must approve changes, and a separate test environment must be deployed. Operations Overview Citrix Rollups and hotfixes are applied sporadically throughout the Citrix farms. The following table details the implementation of Citrix Rollups. Backups of the Aberdeen, Houston, and London SQL databases are conducted daily via SQL. A nightly backup of the Windows server ensures that the local SQL backup is captured. However, the restoration process has not been tested. The remaining locations lack SQL administrators, so it is unclear if SQL backups are being performed. The CIO recognizes this gap and is taking steps to ensure that all Citrix databases are routinely backed up. For the short term, the SQL administrators in the Houston location will assume responsibility for the SQL backups in the locations that lack SQL administrators.

Since each region has operated independently, no central disaster recovery plan exists. Corporate IT hopes to provide a seamless disaster recovery solution for all locations and believes that it may be possible to utilize regional resources with minimal overhead. Corporate IT feels that it is likely that, in the event of a disaster, only a subset of a region s end users would require a disaster recovery solution, and believes that approximately 50 percent of regional end users would be a good starting point. Monitoring Overview The Houston location is the only location using EdgeSight. Corporate IT uses EdgeSight for license trending and occasional end-user troubleshooting. Interviews with the IT staff using EdgeSight revealed that EdgeSight could probably be better utilized. The help desk staff has tried using EdgeSight, but has felt overwhelmed and would prefer a much simpler interface to troubleshoot end-user issues. CGE recently purchased Tivoli, an antivirus program, and is in the process of rolling it out to all locations. Corporate IT has requested from Citrix Consulting any specific monitoring metrics and alerts related to the Citrix environment. CGE realizes that effective monitoring will allow them to be proactive in addressing issues before they cause critical outages. The following is CGE s current antivirus policy: Periodic scanning of servers must be conducted at 1:00 a.m., local time, each morning. All workstations and servers must have antivirus software installed, and real-time scanning must be enabled. Periodic updating of antivirus software is required. Currently, antivirus updates are automatically delivered at 8:00 a.m., 1:00 p.m., 4:00 p.m., and 11:00 p.m., local time. Only vendor-required exclusions may be used, and all exclusions must be configured for both real-time and periodic scans. Real-time antivirus scanning must be configured to scan files when they are accessed and written. All servers must be configured to scan their local drives, and all remote network drive scanning must be disabled. Corporate IT has shared several Citrix articles relating to Citrix product antivirus exclusions with the regions. It is unclear if the regions have implemented these exclusions.

Testlet 1 Executive Summary Project Overview CGE is a global, diversified, upstream (exploration and production) oil and gas company headquartered in North America. CGE s three main operating areas are North America, Europe, and Southeast Asia. CGE also has a portfolio of international exploration opportunities. CGE began in North America as a small, upstream oil and gas company. Through acquisitions, CGE grew quickly and acquired companies globally. This led to a decentralized IT model, both from systems and personnel perspectives. CGE currently utilizes several Citrix technologies to provide application virtualization to a global end-user base spread across several continents. Its current IT model for application virtualization is based on regional locations; each region hosts its own Citrix environment to support its local end-user base. CGE is moving toward a global IT model in which the entire application and desktop virtualization environment will be hosted in three data centers, each with a highly available NetScaler pair. CGE would like to provide dedicated desktops to some end-user groups to alleviate past issues with applications and performance. In addition, an Internet upgrade project is underway to eliminate slow connections at all sites. This will improve latency and bandwidth issues throughout the environments. CGE engaged Citrix Consulting to determine whether best practices are being followed in its existing Citrix environments; to provide a design document for a new, consolidated Citrix environment; and to point out risks that should be resolved before moving to this new environment. This deliverable represents the output of the requirements gathering phase and will be used as an input during the architectural design phase of this engagement. Through interactive meetings, Citrix Consulting obtained information regarding CGE s existing Citrix XenApp environments and strategic goals. By reviewing this information, CGE can understand and methodically address those areas that represent the most profound risks, improve various facets of its current environments, and prepare for the future design phase of a consolidated environment. Project Goals During the course of the project, CGE and Citrix Consulting identified a number of project goals. The following summarizes these goals: Perform a detailed assessment of the Citrix components supporting the existing Citrix environments, which include XenApp 6.x, XenServer, and NetScaler Gateway. Review relevant peripheral components that support the existing Citrix environments (for example, Active Directory, storage, SQL, networking) to determine if each can support current production workloads and a new Citrix environment. Identify operational and environmental improvements to better account for the environments growth. Overview CGE has locations spread across three primary regions North America, Europe, and Southeast Asia with its primary headquarters located in Houston. Sub regions exist within each region, each with its own Citrix infrastructure. Once power and cooling upgrades are complee, Houston will be the primary datacenter and London will be the secondary datacenter. The following diagram details the locations and network connection types.

Business Layer Overview Since CGE expanded quickly through acquisitions, corporate IT left infrastructure management up to the acquired companies. As a result, some regions have wellrun Citrix environments, while others experience critical outages that simultaneously affect hundreds of end users. CGE s CIO, who has been with CGE for slightly less than a year, was hired to be the central point for IT across all regions. The CIO has engaged with the various business units to understand their processes and received various complaints about the stability of the existing Citrix infrastructures. The CIO feels that the majority of Citrix infrastructure issues are due to a lack of centralized control and common platforms. Some regions have older versions of XenApp, while some are more current. As CGE moves forward, the CIO plans to use a single vendor for the entire solution, and wants to ensure that the new infrastructure is virtualized and fault tolerant. End-User Layer Overview CGE has 10,350 employees, approximately 4,700 of which access the Citrix environments daily. Peak logon times are Monday through Friday, from 8:00 a.m. 10:00 a.m., based on local, regional time zones. Technicians and engineers are shift workers who rotate to accommodate a 24 hours a day, seven days a week schedule. End user distribution is as follows:

The majority of end users connect using CGE-owned HP laptop and desktop devices. Over 90 percent of these devices are Windows 7-based, as CGE is in the process of completing a Windows XP to Windows 7 migration. CGE has standardized all these devices on Citrix Online Plug-in for Windows12.1, and is in the process of testing Receiver for Windows 4.2. In the past, some end users have complained about slowness when typing, which may indicate issues with latency. CGE also allows end users to connect using non-corporate-owned devices.

CGE is moving toward a global IT model in which the entire application and desktop virtualization environment will be hosted in three data centers, each with a highly available NetScaler pair. CGE would like to provide dedicated desktops to some end-user groups to alleviate past issues with applications and performance. In addition, an Internet upgrade project is underway to eliminate slow connections at all sites. This will improve latency and bandwidth issues throughout the environments. CGE engaged Citrix Consulting to determine whether best practices are being followed in its existing Citrix environments; to provide a design document for a new, consolidated Citrix environment; and to point out risks that should be resolved before moving to this new environment. This deliverable represents the output of the requirements gathering phase and will be used as an input during the architectural design phase of this engagement. Through interactive meetings, Citrix Consulting obtained information regarding CGE s existing Citrix XenApp environments and strategic goals. By reviewing this information, CGE can understand and methodically address those areas that represent the most profound risks, improve various facets of its current environments, and prepare for the future design phase of a consolidated environment. Project Goals During the course of the project, CGE and Citrix Consulting identified a number of project goals. The following summarizes these goals: Perform a detailed assessment of the Citrix components supporting the existing Citrix environments, which include XenApp 6.x, XenServer, and NetScaler Gateway. Review relevant peripheral components that support the existing Citrix environments (for example, Active Directory, storage, SQL, networking) to determine if each can support current production workloads and a new Citrix environment. Identify operational and environmental improvements to better account for the environments growth. Overview CGE has locations spread across three primary regions North America, Europe, and Southeast Asia with its primary headquarters located in Houston. Sub regions exist within each region, each with its own Citrix infrastructure. Once power and cooling upgrades are complee, Houston will be the primary datacenter and London will be the secondary datacenter. The following diagram details the locations and network connection types.

Business Layer Overview Since CGE expanded quickly through acquisitions, corporate IT left infrastructure management up to the acquired companies. As a result, some regions have wellrun Citrix environments, while others experience critical outages that simultaneously affect hundreds of end users. CGE s CIO, who has been with CGE for slightly less than a year, was hired to be the central point for IT across all regions. The CIO has engaged with the various business units to understand their processes and received various complaints about the stability of the existing Citrix infrastructures. The CIO feels that the majority of Citrix infrastructure issues are due to a lack of centralized control and common platforms. Some regions have older versions of XenApp, while some are more current. As CGE moves forward, the CIO plans to use a single vendor for the entire solution, and wants to ensure that the new infrastructure is virtualized and fault tolerant. End-User Layer Overview CGE has 10,350 employees, approximately 4,700 of which access the Citrix environments daily. Peak logon times are Monday through Friday, from 8:00 a.m. 10:00 a.m., based on local, regional time zones. Technicians and engineers are shift workers who rotate to accommodate a 24 hours a day, seven days a week schedule. End user distribution is as follows:

The majority of end users connect using CGE-owned HP laptop and desktop devices. Over 90 percent of these devices are Windows 7-based, as CGE is in the process of completing a Windows XP to Windows 7 migration. CGE has standardized all these devices on Citrix Online Plug-in for Windows12.1, and is in the process of testing Receiver for Windows 4.2. In the past, some end users have complained about slowness when typing, which may indicate issues with latency. CGE also allows end users to connect using non-corporate-owned devices. Many end users connect from personal computers and mobile devices such as Apple ipads and iphones. End users are instructed to download Citrix Receiver from either the Citrix website or the Android or Apple app stores. End users can be grouped into six separate categories: Executives/Management Regional upper- and mid-level management staff. Back Office End users that provide functions such as accounting, administration, human resources, and finance. Research End users focus mainly on discovering new energy fields and sources. Engineers End users who work with technicians in a senior lead role for both technical and management functions. There is approximately one engineer for every five technicians. Technicians Field workers who service the oil and gas equipment. Sales Primary customer-facing group. End-user groups and numbers are as follows:

The engineers, technicians, and research groups access Citrix applications primarily in an office-type environment, but may need to access these applications while in the gas and oil fields. In these scenarios, end users connect to Citrix using local Internet connections, ranging from a wireless access point to a tethered mobile device. To prevent printer driver issues and sprawl, CGE tries to limit end users to their default printer when accessing Citrix. The IT department at CGE s headquarters has mandated that only the Citrix Universal Print Driver be utilized. As each region manages its own Citrix infrastructure, this has been difficult to enforce. Each end user s home directory is mapped when accessing a Citrix session; the drive-mapping letter varies based on the end user s region. End-user data is stored on different network device types and shares ranging from a Windows CIFS share to an NAS appliance. Corporate IT is unsure if end-user data is being backed up in all regions. CGE hopes to implement formal, corporate-wide standards in the new Citrix environment. Access Layer Overview Since each region has its own Citrix environment, end users are fairly isolated within their specific regions. In each region, NetScaler Gateway and Web Interface provide access for internal and external end users. In some regions, Citrix Secure Gateway is still being utilized for external access. This is primarily due to a past budget constraint, but CGE hopes to provide a redundant and fault-tolerant Citrix access solution for all regions with the new environment. Confusion with the use of the appropriate URL also occurs for end users travelling among regions. A common access point that routes end users to their closest datacenter would most

likely reduce this confusion. As CGE is sensitive to the research that is being conducted toward the development of new energy types and methods, external access to the Citrix environment must be as secure as possible. Currently, internal and external end users employ single-factor authentication; however, the development of a two-factor authentication process is desired. Access Controllers Overview The following table outlines the utilization of Web Interface, StoreFront, NetScaler Gateway, and Citrix Secure Gateway in the various Citrix environments. Resource Layer Personalization Overview The following table outlines the current overall profile strategy:

Corporate IT would like to streamline the profile management solution. Numerous end users complain about slow logon and logoff times, and routine profile corruption is also a concern. It is common for IT to have to reset end-user profiles on a daily basis. CGE hopes to provide a stable end-user profile platform by implementing a standardized set of hardware to host profiles and by employing Citrix Profile Management. Citrix policies vary from region to region, but corporate IT has tried to enforce the following policy settings (at a minimum): Technicians and engineers require USB mapping for various field devices such as flow meters and sonar devices. Since the majority of the remaining end-user groups probably do not need USB mapping, this could be disabled for those groups in the new environment. Corporate IT feels that most end users require only their default printer within a Citrix session. However, other end-user groups (primarily Back Office) need to access multiple printers with advanced printing functionality, such as stapling. In all cases, the need to limit native print drivers is critical. Applications Overview The majority of end users utilize published applications delivered through one of the regional XenApp farms. Some end-user groups require a full desktop instead of published applications. CGE mandates that no new software (agents) may be deployed in the current desktop infrastructure.

The following table provides additional details about the applications and desktops used throughout the Citrix environments.

Image Design Overview The following table outlines current application specifics. All servers are Windows 2008 R2 running XenApp 6.5, and all are virtual machines. Applications are delivered based on grouping. For example, Office Suite is installed on a dedicated set of servers.

Control Layer Infrastructure Services Active Directory As the solution integrates with Active Directory, resources must be easy to manage and maintain within the directory structure. The following details CGE s typical organizational unit (OU) structure for the XenApp environments. Overview

Databases Overview

CGE manages seven XenApp 6.5 farms one for each region. A variety of SQL server versions host the farm databases. Some databases are located on a shared SQL cluster, while others are standalone. The following table provides an overview of each environment, the database location, and the database configuration. Licensing Overview As each region currently manages its own Citrix infrastructure, licensing types vary from region to region. Some regions have more licenses than end users, while others sometimes reach their limit. Each region has its own Citrix and Microsoft license servers. Corporate IT will be consolidating the Citrix and Microsoft licenses under a common corporate agreement in the new Citrix environment. This will allow for better cost control and appropriate distribution of licenses. If needed, additional licenses will be procured to support the new Citrix solution. This may involve purchasing additional Microsoft and Citrix licenses to support a disaster recovery model. The following details the current Citrix and Microsoft license types.

XenApp Controllers Overview All regions use virtualized XenApp 6.5 servers. Some regions currently use Provisioning Services 6.1, but CGE wants to simplify management processes by moving to Provisioning Services 7.6 in each region. Although there are no test farms in the current Citrix environments, CGE would like to incorporate dedicated test environments in the new Citrix solution. These new test environments should utilize a minimum of storage. The following table details the XenApp environments for each region.

End users in some regions often complain about slow application enumeration and launch issues. Corporate IT hopes that these issues will be resolved with the new Citrix solution.

Hardware Layer Storage Overview Depending on the region, the physical hosts that provide hardware virtualization use a variety of local and SAN-based storage. Using local storage has prevented virtual machines from moving to another host in the event of a host failure, creating some regional capacity issues. Corporate IT is unsure if end-user data is being backed up in all regions. CGE hopes to implement global formal standards in the new Citrix environment. A fault-tolerant solution is required for hardware virtualization and end-user data storage. The following table describes the different storage types based on region: Networking Overview CGE utilizes regional private networks. Not all regions connect directly to each other. The network links range in size from 5 Mbps to 10 Mbps. The networks are congested at times among regions, causing large file copies to be scheduled during off hours to minimize disruption. CGE currently has a project underway to increase the bandwidth among regions and reduce latency for the new Citrix environment. The following diagram details the links among the regions.

Each region has a separate Internet connection of varying capacity and utilizes its own local network connection for Internet traffic. Microsoft and routing policies are in place to direct Internet-bound traffic to use this local Internet connection. The goal was to reduce the amount traffic on the links among regions, saving bandwidth for interregional traffic. For external Citrix access, each region uses its local Internet connection. The NetScaler Gateways and Citrix Secure Gateways are placed in a demilitarized zone (DMZ). Appropriate firewall ports are configured to allow the Citrix traffic to navigate to the internal resources. Control Hosts Overview As CGE acquired several companies within a short period of time, it did not change any of the acquired companies infrastructures. This has resulted in regional inconsistency in hypervisor platforms and versions and with hardware vendors. Corporate IT hopes to streamline the infrastructure to ensure corporate standards are followed. At a minimum, a standard hypervisor platform must be used to allow IT resources to train on a common hypervisor platform and to quickly assist in other regions when needed. For the new Citrix solution, CGE has budgeted for the replacement of aging infrastructure equipment, where needed, including the hypervisor platform. Procurement of the best infrastructure components within this planned budget must be ensured. Operations Layer Support Overview In the current configuration, each region is responsible for supporting its end users and infrastructure. This often leads to confusion for end users who travel, as

well as the for the help desk members who work with these end users. Corporate IT hopes to develop a centralized support structure from the end-user layer to the infrastructure layer. The CIO envisions a model that allows an end user to call one number for support. Regional staff will support the help desk 24 hours a day, seven days a week. If first-tier help desk support is unable to resolve the issue in a timely manner, a second-tier support team would be engaged. In order to facilitate this troubleshooting model, the first-tier help desk and second-tier support teams would require access to the Citrix infrastructure. The CIO would prefer a centralized console for the help desk team, but it is not a requirement. In the past, some regions had training budgets, while others did not. This has often resulted in lengthy resolution of issues due to improper training. To alleviate this, the CIO has mandated that the first-tier help desk and second-tier support teams be properly trained in the products being implemented in the new Citrix solution. Testing and Change Control Overview An analysis revealed that none of the regions have a proper test environment. At best, some regions have a few test XenApp servers in their production farms that are used for testing. In addition, the procedures for implementing changes to the systems vary from region to region. Some regions have a documented change control process, while others install changes as application owners or end users request them. This has resulted in overall poor performance of the Citrix environments and has caused outages in some regions. The CIO has mandated that in the new Citrix solution, a change control board must approve changes, and a separate test environment must be deployed. Operations Overview Citrix Rollups and hotfixes are applied sporadically throughout the Citrix farms. The following table details the implementation of Citrix Rollups. Backups of the Aberdeen, Houston, and London SQL databases are conducted daily via SQL. A nightly backup of the Windows server ensures that the local SQL backup is captured. However, the restoration process has not been tested. The remaining locations lack SQL administrators, so it is unclear if SQL backups are being performed. The CIO recognizes this gap and is taking steps to ensure that all Citrix databases are routinely backed up. For the short term, the SQL administrators in the Houston location will assume responsibility for the SQL backups in the locations that lack SQL administrators.

Since each region has operated independently, no central disaster recovery plan exists. Corporate IT hopes to provide a seamless disaster recovery solution for all locations and believes that it may be possible to utilize regional resources with minimal overhead. Corporate IT feels that it is likely that, in the event of a disaster, only a subset of a region s end users would require a disaster recovery solution, and believes that approximately 50 percent of regional end users would be a good starting point. Monitoring Overview The Houston location is the only location using EdgeSight. Corporate IT uses EdgeSight for license trending and occasional end-user troubleshooting. Interviews with the IT staff using EdgeSight revealed that EdgeSight could probably be better utilized. The help desk staff has tried using EdgeSight, but has felt overwhelmed and would prefer a much simpler interface to troubleshoot end-user issues. CGE recently purchased Tivoli, an antivirus program, and is in the process of rolling it out to all locations. Corporate IT has requested from Citrix Consulting any specific monitoring metrics and alerts related to the Citrix environment. CGE realizes that effective monitoring will allow them to be proactive in addressing issues before they cause critical outages. The following is CGE s current antivirus policy: Periodic scanning of servers must be conducted at 1:00 a.m., local time, each morning. All workstations and servers must have antivirus software installed, and real-time scanning must be enabled. Periodic updating of antivirus software is required. Currently, antivirus updates are automatically delivered at 8:00 a.m., 1:00 p.m., 4:00 p.m., and 11:00 p.m., local time. Only vendor-required exclusions may be used, and all exclusions must be configured for both real-time and periodic scans. Real-time antivirus scanning must be configured to scan files when they are accessed and written. All servers must be configured to scan their local drives, and all remote network drive scanning must be disabled. Corporate IT has shared several Citrix articles relating to Citrix product antivirus exclusions with the regions. It is unclear if the regions have implemented these exclusions QUESTION 1 Which licensing changes should a Citrix Architect recommend to enable the HDX Mobile feature in CGE's Jurong and Makassar offices?

It simplifies home drive cleanup. C. It minimizes the required storage needed for folder redirection. D. It improves data accuracy in volatile environments.

Correct Answer: D /Reference: : Enable Active Write-Back to allow Citrix UPM to synchronize profile data during the user session, instead of waiting to synchronize the entire profile upon user logout. This prevents profiles from not synchronizing all data and from being corrupted. Active Write-Back prevents this by synchronizing files during the entire user session, so when the user logs off, there will be minimal profile data (if any) that must be synchronized. A direct benefit of this setting is that if a virtual desktop crashes or gets reset instead of properly shutdown, users need not have to worry about files not being synchronized.

Testlet 1 Executive Summary Project Overview CGE is a global, diversified, upstream (exploration and production) oil and gas company headquartered in North America. CGE s three main operating areas are North America, Europe, and Southeast Asia. CGE also has a portfolio of international exploration opportunities. CGE began in North America as a small, upstream oil and gas company. Through acquisitions, CGE grew quickly and acquired companies globally. This led to a decentralized IT model, both from systems and personnel perspectives. CGE currently utilizes several Citrix technologies to provide application virtualization to a global end-user base spread across several continents. Its current IT model for application virtualization is based on regional locations; each region hosts its own Citrix environment to support its local end-user base. CGE is moving toward a global IT model in which the entire application and desktop virtualization environment will be hosted in three data centers, each with a highly available NetScaler pair. CGE would like to provide dedicated desktops to some end-user groups to alleviate past issues with applications and performance. In addition, an Internet upgrade project is underway to eliminate slow connections at all sites. This will improve latency and bandwidth issues throughout the environments. CGE engaged Citrix Consulting to determine whether best practices are being followed in its existing Citrix environments; to provide a design document for a new, consolidated Citrix environment; and to point out risks that should be resolved before moving to this new environment. This deliverable represents the output of the requirements gathering phase and will be used as an input during the architectural design phase of this engagement. Through interactive meetings, Citrix Consulting obtained information regarding CGE s existing Citrix XenApp environments and strategic goals. By reviewing this information, CGE can understand and methodically address those areas that represent the most profound risks, improve various facets of its current environments, and prepare for the future design phase of a consolidated environment. Project Goals During the course of the project, CGE and Citrix Consulting identified a number of project goals. The following summarizes these goals: Perform a detailed assessment of the Citrix components supporting the existing Citrix environments, which include XenApp 6.x, XenServer, and NetScaler Gateway. Review relevant peripheral components that support the existing Citrix environments (for example, Active Directory, storage, SQL, networking) to determine if each can support current production workloads and a new Citrix environment. Identify operational and environmental improvements to better account for the environments growth. Overview CGE has locations spread across three primary regions North America, Europe, and Southeast Asia with its primary headquarters located in Houston. Sub regions exist within each region, each with its own Citrix infrastructure. Once power and cooling upgrades are complee, Houston will be the primary datacenter and London will be the secondary datacenter. The following diagram details the locations and network connection types.

Business Layer Overview Since CGE expanded quickly through acquisitions, corporate IT left infrastructure management up to the acquired companies. As a result, some regions have wellrun Citrix environments, while others experience critical outages that simultaneously affect hundreds of end users. CGE s CIO, who has been with CGE for slightly less than a year, was hired to be the central point for IT across all regions. The CIO has engaged with the various business units to understand their processes and received various complaints about the stability of the existing Citrix infrastructures. The CIO feels that the majority of Citrix infrastructure issues are due to a lack of centralized control and common platforms. Some regions have older versions of XenApp, while some are more current. As CGE moves forward, the CIO plans to use a single vendor for the entire solution, and wants to ensure that the new infrastructure is virtualized and fault tolerant. End-User Layer Overview CGE has 10,350 employees, approximately 4,700 of which access the Citrix environments daily. Peak logon times are Monday through Friday, from 8:00 a.m. 10:00 a.m., based on local, regional time zones. Technicians and engineers are shift workers who rotate to accommodate a 24 hours a day, seven days a week schedule. End user distribution is as follows:

The majority of end users connect using CGE-owned HP laptop and desktop devices. Over 90 percent of these devices are Windows 7-based, as CGE is in the process of completing a Windows XP to Windows 7 migration. CGE has standardized all these devices on Citrix Online Plug-in for Windows12.1, and is in the process of testing Receiver for Windows 4.2. In the past, some end users have complained about slowness when typing, which may indicate issues with latency. CGE also allows end users to connect using non-corporate-owned devices. Many end users connect from personal computers and mobile devices such as Apple ipads and iphones. End users are instructed to download Citrix Receiver from either the Citrix website or the Android or Apple app stores. End users can be grouped into six separate categories: Executives/Management Regional upper- and mid-level management staff. Back Office End users that provide functions such as accounting, administration, human resources, and finance. Research End users focus mainly on discovering new energy fields and sources. Engineers End users who work with technicians in a senior lead role for both technical and management functions. There is approximately one engineer for every five technicians. Technicians Field workers who service the oil and gas equipment. Sales Primary customer-facing group. End-user groups and numbers are as follows:

The engineers, technicians, and research groups access Citrix applications primarily in an office-type environment, but may need to access these applications while in the gas and oil fields. In these scenarios, end users connect to Citrix using local Internet connections, ranging from a wireless access point to a tethered mobile device. To prevent printer driver issues and sprawl, CGE tries to limit end users to their default printer when accessing Citrix. The IT department at CGE s headquarters has mandated that only the Citrix Universal Print Driver be utilized. As each region manages its own Citrix infrastructure, this has been difficult to enforce. Each end user s home directory is mapped when accessing a Citrix session; the drive-mapping letter varies based on the end user s region. End-user data is stored on different network device types and shares ranging from a Windows CIFS share to an NAS appliance. Corporate IT is unsure if end-user data is being backed up in all regions. CGE hopes to implement formal, corporate-wide standards in the new Citrix environment. Access Layer Overview Since each region has its own Citrix environment, end users are fairly isolated within their specific regions. In each region, NetScaler Gateway and Web Interface provide access for internal and external end users. In some regions, Citrix Secure Gateway is still being utilized for external access. This is primarily due to a past budget constraint, but CGE hopes to provide a redundant and fault-tolerant Citrix access solution for all regions with the new environment. Confusion with the use of the appropriate URL also occurs for end users travelling among regions. A common access point that routes end users to their closest datacenter would most

likely reduce this confusion. As CGE is sensitive to the research that is being conducted toward the development of new energy types and methods, external access to the Citrix environment must be as secure as possible. Currently, internal and external end users employ single-factor authentication; however, the development of a two-factor authentication process is desired. Access Controllers Overview The following table outlines the utilization of Web Interface, StoreFront, NetScaler Gateway, and Citrix Secure Gateway in the various Citrix environments. Resource Layer Personalization Overview The following table outlines the current overall profile strategy:

Corporate IT would like to streamline the profile management solution. Numerous end users complain about slow logon and logoff times, and routine profile corruption is also a concern. It is common for IT to have to reset end-user profiles on a daily basis. CGE hopes to provide a stable end-user profile platform by implementing a standardized set of hardware to host profiles and by employing Citrix Profile Management. Citrix policies vary from region to region, but corporate IT has tried to enforce the following policy settings (at a minimum): Technicians and engineers require USB mapping for various field devices such as flow meters and sonar devices. Since the majority of the remaining end-user groups probably do not need USB mapping, this could be disabled for those groups in the new environment. Corporate IT feels that most end users require only their default printer within a Citrix session. However, other end-user groups (primarily Back Office) need to access multiple printers with advanced printing functionality, such as stapling. In all cases, the need to limit native print drivers is critical. Applications Overview The majority of end users utilize published applications delivered through one of the regional XenApp farms. Some end-user groups require a full desktop instead of published applications. CGE mandates that no new software (agents) may be deployed in the current desktop infrastructure.

The following table provides additional details about the applications and desktops used throughout the Citrix environments.

Image Design Overview The following table outlines current application specifics. All servers are Windows 2008 R2 running XenApp 6.5, and all are virtual machines. Applications are delivered based on grouping. For example, Office Suite is installed on a dedicated set of servers.

Control Layer Infrastructure Services Active Directory As the solution integrates with Active Directory, resources must be easy to manage and maintain within the directory structure. The following details CGE s typical organizational unit (OU) structure for the XenApp environments. Overview

Databases Overview

CGE manages seven XenApp 6.5 farms one for each region. A variety of SQL server versions host the farm databases. Some databases are located on a shared SQL cluster, while others are standalone. The following table provides an overview of each environment, the database location, and the database configuration. Licensing Overview As each region currently manages its own Citrix infrastructure, licensing types vary from region to region. Some regions have more licenses than end users, while others sometimes reach their limit. Each region has its own Citrix and Microsoft license servers. Corporate IT will be consolidating the Citrix and Microsoft licenses under a common corporate agreement in the new Citrix environment. This will allow for better cost control and appropriate distribution of licenses. If needed, additional licenses will be procured to support the new Citrix solution. This may involve purchasing additional Microsoft and Citrix licenses to support a disaster recovery model. The following details the current Citrix and Microsoft license types.

XenApp Controllers Overview All regions use virtualized XenApp 6.5 servers. Some regions currently use Provisioning Services 6.1, but CGE wants to simplify management processes by moving to Provisioning Services 7.6 in each region. Although there are no test farms in the current Citrix environments, CGE would like to incorporate dedicated test environments in the new Citrix solution. These new test environments should utilize a minimum of storage. The following table details the XenApp environments for each region.

End users in some regions often complain about slow application enumeration and launch issues. Corporate IT hopes that these issues will be resolved with the new Citrix solution.

Hardware Layer Storage Overview Depending on the region, the physical hosts that provide hardware virtualization use a variety of local and SAN-based storage. Using local storage has prevented virtual machines from moving to another host in the event of a host failure, creating some regional capacity issues. Corporate IT is unsure if end-user data is being backed up in all regions. CGE hopes to implement global formal standards in the new Citrix environment. A fault-tolerant solution is required for hardware virtualization and end-user data storage. The following table describes the different storage types based on region: Networking Overview CGE utilizes regional private networks. Not all regions connect directly to each other. The network links range in size from 5 Mbps to 10 Mbps. The networks are congested at times among regions, causing large file copies to be scheduled during off hours to minimize disruption. CGE currently has a project underway to increase the bandwidth among regions and reduce latency for the new Citrix environment. The following diagram details the links among the regions.

Each region has a separate Internet connection of varying capacity and utilizes its own local network connection for Internet traffic. Microsoft and routing policies are in place to direct Internet-bound traffic to use this local Internet connection. The goal was to reduce the amount traffic on the links among regions, saving bandwidth for interregional traffic. For external Citrix access, each region uses its local Internet connection. The NetScaler Gateways and Citrix Secure Gateways are placed in a demilitarized zone (DMZ). Appropriate firewall ports are configured to allow the Citrix traffic to navigate to the internal resources. Control Hosts Overview As CGE acquired several companies within a short period of time, it did not change any of the acquired companies infrastructures. This has resulted in regional inconsistency in hypervisor platforms and versions and with hardware vendors. Corporate IT hopes to streamline the infrastructure to ensure corporate standards are followed. At a minimum, a standard hypervisor platform must be used to allow IT resources to train on a common hypervisor platform and to quickly assist in other regions when needed. For the new Citrix solution, CGE has budgeted for the replacement of aging infrastructure equipment, where needed, including the hypervisor platform. Procurement of the best infrastructure components within this planned budget must be ensured. Operations Layer Support Overview In the current configuration, each region is responsible for supporting its end users and infrastructure. This often leads to confusion for end users who travel, as

well as the for the help desk members who work with these end users. Corporate IT hopes to develop a centralized support structure from the end-user layer to the infrastructure layer. The CIO envisions a model that allows an end user to call one number for support. Regional staff will support the help desk 24 hours a day, seven days a week. If first-tier help desk support is unable to resolve the issue in a timely manner, a second-tier support team would be engaged. In order to facilitate this troubleshooting model, the first-tier help desk and second-tier support teams would require access to the Citrix infrastructure. The CIO would prefer a centralized console for the help desk team, but it is not a requirement. In the past, some regions had training budgets, while others did not. This has often resulted in lengthy resolution of issues due to improper training. To alleviate this, the CIO has mandated that the first-tier help desk and second-tier support teams be properly trained in the products being implemented in the new Citrix solution. Testing and Change Control Overview An analysis revealed that none of the regions have a proper test environment. At best, some regions have a few test XenApp servers in their production farms that are used for testing. In addition, the procedures for implementing changes to the systems vary from region to region. Some regions have a documented change control process, while others install changes as application owners or end users request them. This has resulted in overall poor performance of the Citrix environments and has caused outages in some regions. The CIO has mandated that in the new Citrix solution, a change control board must approve changes, and a separate test environment must be deployed. Operations Overview Citrix Rollups and hotfixes are applied sporadically throughout the Citrix farms. The following table details the implementation of Citrix Rollups. Backups of the Aberdeen, Houston, and London SQL databases are conducted daily via SQL. A nightly backup of the Windows server ensures that the local SQL backup is captured. However, the restoration process has not been tested. The remaining locations lack SQL administrators, so it is unclear if SQL backups are being performed. The CIO recognizes this gap and is taking steps to ensure that all Citrix databases are routinely backed up. For the short term, the SQL administrators in the Houston location will assume responsibility for the SQL backups in the locations that lack SQL administrators.
