4 The evolution of virtualization: Virtualization is turning today s data centers into strategic assets Virtualization technologies have created a major paradigm shift. In the past, organizations worked with a model where applications and services were tightly associated with a physical infrastructure. The physical infrastructure consisted of servers, storage, network cables, switches, routers, and firewalls. All of these components were separate pieces of hardware on the network, and specialized teams were dedicated to managing these IT assets. Abstracting the physical infrastructure away from applications and services by using virtualization technologies has disrupted the traditional ways of thinking about data center design. Virtualization technologies make it possible to easily provision IT resources on commodity hardware. In addition, the entire notion of virtualized data centers has evolved by enabling elastic provisioning, metered services, self-service, and resources on demand. When these capabilities are combined with the power of virtualization, IT departments realize the full benefits of deploying virtualized data centers. Virtualization vendors have made significant improvements to their hypervisors, which are thin layers of software that mediate interactions between virtual machines and the physical hardware. These hypervisor vendors have also made major improvements to their management frameworks, which make it possible to automate features such as high availability, dynamic resource allocation, advanced power management, automated storage allocation, and disaster recovery. Cloud computing is the culmination of all the advantages a virtual data center has to offer and is changing the way IT resources are utilized. Users want the ability to access infrastructure resources how and when they choose. IT teams are asked to accommodate this shift in the consumption model but still deal with the security, compatibility, and compliance issues associated with delivering that convenience to application business owners and developers. Cloud computing solves these problems. These combined technological advances enable a more efficient service delivery model that provides key business benefits to any organization looking for lower TCO and higher ROI. These advantages stem from key areas where virtualization makes a major difference, which include: Lower capital and operational expenditures Increased IT agility in servicing customer requests Enhanced business continuity Streamlined solution development and deployment Improved security and management A stronger foundation for future innovations, such as private clouds Lower capital and operational expenditures Historically, when an organization needed to deploy a new service or application, many steps and man-hours were necessary to determine the requirements for the server hardware, for the hardware installation, and for the network infrastructure that was needed to support the new hardware deployment. Virtualization significantly reduces hardware capital expenditures and cost of IT overhead involved with delivering new services or applications. Provisioning virtual machines is much faster than setting up physical servers, and the new application or service can be tested, deployed, and even failed over in a fraction of the time that it takes in a physical deployment. In addition to the reduction in capital expenditures due to fewer physical servers, IT organizations will see decreased operating expenditures because of reductions in support overhead. Because fewer physical servers are required, there are also significant reductions in data center floor space, power costs, HVAC equipment, network cables and switches, and labor costs for maintenance and repair. The combination of lower capital and operating expenditures is one of the primary drivers for moving to a virtualized data center. Fewer physical servers means reductions in: Data center floor space Power costs HVAC equipment Network cables and switches Labor costs for hardware maintenance and repair Increased IT agility in servicing customer requests Business units need to act quickly to show value back to their company. If a new service or application can provide a competitive advantage, the group wants it online now. In a traditional physical data center, there was a significant lag between the time from envisioning to deployment due to hardware procurement and installation delays. With a virtualized data center, new services and applications can be tested and deployed in record time because it takes only minutes to create a new virtual machine. 4

5 Enhanced business continuity Achieving high levels of application availability prior to virtualization could be complex and costly. IT groups needed to buy multiple physical servers, not only for the primary data center, but also for a failover location, so that the backup data center could be activated in the event of a disaster at the primary data center. Virtualization makes operating systems highly portable and therefore reduces the cost and complexity of deploying live failover environments. Streamlined solution development and deployment Software development teams often require a number of servers dedicated to the software development process. Complex, multitier applications require even more servers. Prior to virtualization, staging a development environment was time consuming and costly. Virtualization streamlines this process as administrators of virtualized data centers can configure development and test environments that let developers quickly create virtual machines, complete with the operating systems, storage, and virtual networks. Developers can focus on creating software that gives their businesses and customers an edge in a competitive global marketplace. Improved security and management Virtualization gives IT organizations enhanced control over the application and service infrastructure. Through a single pane of glass, server administrators can see the status of the virtual machines, their physical host servers, the storage used by the virtual infrastructure, and the operating systems running on those virtual machines. Automated alerting and reporting is integrated in the management console. A single IT group can now monitor resources that formerly required multiple groups, thus reducing administrative costs and increasing security and control over the entire virtualized data center. A stronger foundation for future innovations, such as private clouds Virtualization s new compute model lays a solid foundation for efficient and agile IT. This paves the way for rapid assessment and adoption of future data center workloads. One example is the deployment of a private cloud. A private cloud provides total control and private use of cloud resources and legacy resources that IT owns. These resources are combined to form a complete compute platform or enterprise-wide data center through aggregation and federation, regardless of their actual physical characteristics or location. The private cloud is the full realization and instantiation of all that virtualization and advanced management of a fully virtualized environment has to offer. Virtualizing mission-critical Microsoft applications and services Given the number of advantages that can accrue by virtualizing applications and services, you may want to consider moving your current Microsoft Windows-based servers to a virtual environment. In this section, we ll examine some mission-critical Microsoft applications and services and see what specific benefits you can gain by virtualizing them. Mission-critical Microsoft applications Microsoft application owners have historically been concerned about virtualizing key applications such as Microsoft Exchange Server, Microsoft Office SharePoint Server, and Microsoft SQL Server. However, with major advancements in virtualization and storage technologies, fears that might have been valid in the past no longer apply. With new virtual data center enabling technologies, such as those provided by VMware vsphere and Microsoft Windows Server 2008 R2 Hyper-V, and modern storage, backup, replication, and disaster recovery solutions from EMC, Microsoft application owners can significantly reduce the risk of new technology adoption and push application use cases to their limits. Microsoft application owners have made a number of assumptions about virtualizing their applications that have caused them to be reluctant about moving to a virtualized data center. Some of these assumptions include: Virtualization is not supported Although true in the past, Microsoft has expanded its support for application and operating system virtualization through their Windows Server Virtualization Validation Program. 5

6 The University of Plymouth recently moved a 50,000-seat deployment of Exchange Server 2007 to a virtual deployment and found: The number of server racks decreased from 32 to 2 a 93 percent savings on floor space Estimated annual savings on their electricity bill was about $90,000, saving about 170 tons of CO 2 per year from being produced Exchange Server 2007 runs better in a virtual environment than the university s previous non-virtualized Exchange Server implementations VMware VMotion and VMware High Availability (HA) improve resource availability and flexibility Server provisioning time was reduced from months to minutes Disaster recovery time was reduced from weeks or months to less than an hour Successes have led to a virtualization-first policy Source: The firm doesn t want to be the first one to virtualize the application Virtualization is considered a mainstream technology by Microsoft, and adoption of server virtualization is accelerating each year. Virtual servers can t provide the raw compute power required for applications Modern hypervisors, such as VMware and Hyper-V, can support up to eight virtual processors and up to 255 GB of RAM per virtual machine. Overall, virtualization provides the best server and storage utilization, with a number of virtualization solution providers providing broad functionality, such as dynamic load balancing, virtual machine cloning and backup, and advanced disaster restart and recovery. Microsoft Exchange Server Organizations have a long history of running Exchange Server and see it as a key business enabler. In many instances, a business can come to a stop if Exchange Server mail services become unavailable. IT organizations have built sophisticated back-end infrastructures to support their Exchange Server organizations. Given the success that IT groups have had with their current infrastructures, why would a firm look to virtualizing Exchange Server? Virtualizing Exchange Server enables: Increased capacity and scale Reduced environmental impact Increased flexibility Improved availability Simplified disaster recovery Exchange Server represents a collection of servers that perform different roles. Almost all of these roles lend themselves to virtualization. These include the Active Directory, Client Access Server, Hub Transport Server, Edge Server, and Mailbox Server roles. Only the Unified Messaging Server role is problematic in terms of virtualization, as Microsoft recommends that you deploy this role on a physical server. By virtualizing Exchange Server, you can support more mailboxes on the same hardware. For example, on a 16-core server running Exchange Server where all roles are run on a single server, you can host up to 8,000 mailboxes. However, if you take advantage of the ability to split the Exchange Server roles among different virtual machines and partition resources based on what each server role Figure 1: Virtualizing Exchange Server means supporting more mailboxes on the same hardware requires, you can host up to 16,000 mailboxes on similar hardware. 1 Depending on your deployment, you can see up to a five-times consolidation of Exchange Serverbased servers into virtual machines. This also eliminates the need to provision dedicated standby 6

7 servers. Since the standby servers can be virtualized, you don t need to purchase and provision duplicate hardware to support standby services. Pairing a virtualized Exchange Server organization with EMC storage and replication technologies enables important advantages in the areas of high availability, cost-effectiveness, and simplicity: High availability is simplified by eliminating the complexity of Microsoft failover clustering and presents a single high availability solution to be applied to all Exchange Server roles. The virtualized solution is more cost effective because you can use the standard editions of Windows Server and Exchange Server. Reliability is improved because advanced virtualization technologies include automated routines for moving virtual machines when physical servers need to be serviced or taken offline and replication technologies can be used for system cloning. For Office SharePoint Server deployments, EMC has found that you can reach up to a 13 percent performance increase while realizing power consumption savings of an average of 79 percent. In addition, there are significant cost savings when you consider that you can reach server consolidation ratios of from 5:1 to 10:1. These advantages in high availability, cost-effectiveness, and reliability make virtualizing Exchange Server the best decision not only when you look at total cost of ownership and return on investment, but also when you look at superior high availability and reliability. Microsoft Office SharePoint Server Reflecting an increasing need for global collaborative technology platforms, one in three North American and Western European organizations now use the Office SharePoint Server suite of collaboration information sharing and content management tools. The Office SharePoint Server role as an enterprise collaboration platform calls for high availability and data mobility, two key capabilities provided by virtualization technology. Office SharePoint Server architects and administrators have used a number of methods to ensure that Office SharePoint Server is always online and performs to user expectations. Given a successful physical implementation of Office SharePoint Server, why would an IT organization want to consider virtualizing Office SharePoint Server? Office SharePoint Server is a multitier application that includes at least a web front end, an indexing server, and a back-end database server. Virtualization and advanced storage and replication technologies enable you to: Scale out beyond the Internet Information Services (IIS) connections-per-second limits Save up to 81 percent on power bills Greatly simplify high availability and disaster recovery Employ a consistent replication scheme In terms of performance (omitting the SQL backend which has been virtualized in other tests showing EXCELLENT performance), across three baseline tests, on average: Our virtualized SharePoint Server infrastructure farm out-performed the physical SharePoint farm by 4 percent, But only used 26 percent of the electrical power (watts) required to power the physical server infrastructure put another way, that s a 74 percent power saving over physical, put yet another way, going physical means 380 percent more power Watts versus 3952 Watts. 6 power cords versus 22. Source: virtualgeek.typepad.com/virtual_geek/ 2008/07/virtualizing-sh.html Many IT groups have avoided virtualizing Office SharePoint Server because they ve heard that virtualizing databases is not recommended. In the section about virtualizing SQL Server, you ll see that this is not necessarily true and that there are a number of valid scenarios for virtualizing databases. However, even if an IT group decides not to virtualize the database component of Office SharePoint Server, there are other tiers in an Office SharePoint Server solution that are ideal candidates for virtualization. Many organizations choose to virtualize one tier at a time in a specific order, starting with virtualizing the web front ends, then the query servers, then the application servers, then the indexing servers, and finally the database servers. While potential cost savings and performance will vary with each individual deployment of Office SharePoint Server, EMC has found that you can reach up to a 13 percent performance increase while realizing a power consumption savings of an average of 79 percent. In addition, there are significant cost savings when you consider that you can reach server consolidation ratios of from 5:1 to 10:1. When all tiers of the Office SharePoint Server solution are hosted in a virtualized data center, you can also use advanced high availability and replication technologies to streamline uptime and disaster recovery. For example, by combining technologies from VMware and EMC, you can host the Office SharePoint Server tiers in a VMware vsphere cluster and then use EMC Symmetrix Remote Data Facility (SRDF ), EMC MirrorView, and EMC RecoverPoint to enhance high availability and disaster recovery. Hyper-V used in conjunction with Microsoft System Center Virtual Machine Manager and EMC technologies can also provide a level of high availability and disaster recovery. 7

8 Office SharePoint Server administrators often need to deal with the challenge of re-indexing when they recover from a disaster. By using virtualization, you can keep all tiers of the solution consistent, as you preserve the linkage between the web front-end servers, the indexing servers, and the SQL databases. This avoids the need to re-index because the entire solution is preserved together, not just the individual components. In addition, EMC has consistency technology built into RecoverPoint, EMC CLARiiON, MirrorView, and SRDF. This time-based linkage for federated applications greatly simplifies and speeds recovery so that employees can get back to work as quickly as possible. Microsoft SQL Server SQL Server helps organizations manage data in a variety of formats and is the back-end database for a number of Microsoft and non-microsoft technologies. Organizations can store data from structured, semi-structured, and unstructured documents, such as images and rich media, directly within the database. SQL Server also includes a number of integrated services that enable firms to do more with their data, such as query, search, synchronize, report, and analyze. However, with limited resources and increasing demands, today s enterprises must address the following challenges with SQL Server: Consolidate multiple database applications scattered throughout the enterprise Ensure information access, availability, and continuity Maximize server and storage utilization, and deliver optimal system performance Manage upgrades and migration Reduce demands on limited IT resources and budgets Reduce the complexity of technology choices Manage IT costs, and reduce the risk of business disruption Similar to Exchange Server, SQL Server architects and administrators have devised sophisticated methods to solve these problems. Given the long experience IT groups have had with managing SQL Server deployments, why would they consider virtualizing SQL Server? The major reasons that IT organizations virtualize SQL Server include: Lower cost per database instance Strong isolation of databases Fast and simple scaling and provisioning of databases Enhanced data protection For example, consider a physical SQL Server environment. In this example, there are 20 dualprocessor physical servers, and each of the 20 servers requires a SQL Server Standard Edition license. If you virtualized this SQL Server deployment, you could potentially consolidate the 20 physical servers into two physical servers and use just two SQL Server Enterprise Edition licenses. This leads to significant savings in hardware and software costs. Figure 2: Virtualization enables you to consolidate 20 physical servers and 20 SQL Server licenses to just two physical servers and two SQL Server Enterprise Edition licenses 8

9 There are other benefits your organization can gain by virtualizing SQL Server. Some of these include: Consolidate servers with physical to virtual migration, and support the same number of workloads with better performance on fewer physical servers. Enable workload isolation with a combination of operating system and database isolation. Improve security partitioning by placing resources that belong to different security zones or interests on separate virtual machines. Ensure that each database has the resources it needs by creating resource reservations, priorities, and minimum and maximum limits. Load balance database workloads with the use of advanced virtual high availability and distributed resource allocation technologies. You can provision SQL Server faster in a virtual environment by using virtual provisioning templates, host profiles, and lab and lifecycle management technologies. Scaling SQL Server is easier with the availability of granular adjustment of virtual resource allocations and the ability to dynamically hot add CPUs or memory to support the solution. Virtualization enables you to deploy SQL Server in minutes instead of in weeks. In addition, you can benefit from advanced data protection and management with a combination of virtualization and storage technologies. For example, VMware and EMC provide virtualization and storage and replication solutions that make the following available to SQL Server administrators: Advanced backup with rotating Microsoft Volume Shadow Copy Service (VSS) clones Improved management to seed report and analysis servers and to help set up test and dev cloning Superior high availability powered by virtual machine level switchover Streamlined disaster recovery enabled by technologies such as RecoverPoint and VMware Site Recovery Manager When you combine virtualization with advanced storage and replication technologies, you benefit from lower cost per SQL Server instance, strong isolation, higher security, and the ability to more quickly and easily create and manage all SQL Server database instances. Infrastructure improvements ease the path to virtualizing Microsoft business-critical applications Adopting a virtualized data center for the 21st century provides the ideal opportunity for refreshing the existing data center with the hardware and supporting infrastructure required to optimize virtualization. Key areas for optimization include storage, backup and replication, archiving, and deduplication. Storage Storage performance is critical in a virtualized data center. The virtual data center hosting Microsoft line of business applications will benefit from advances in storage automation that maximize performance. For example, the new EMC Fully Automated Storage Tiering (FAST) technology will automate the movement of data across multiple storage tiers, including flash storage, based upon business policies, predictive models, and real-time access patterns. Storage arrays employing FAST technology leverage flash drive performance together with the cost-effective capacities of SATA hard drives for improved return on investment and lower total cost of ownership. This new technology will be available on EMC Symmetrix V-Max systems later this year. Quality of service is another important performance issue to consider when you virtualize Microsoft mission-critical applications. You can use EMC Navisphere Quality of Service Manager for CLARiiON management to monitor, limit, and set performance targets for applications that run on your CLARiiON storage arrays. You can quickly detect problems when they occur and immediately allocate resources. Navisphere Quality of Service Manager makes it easier to share storage systems and meet service levels, application by application. 9

10 Figure 3: FAST Automates movement and placement of data based on changing needs Backup and restore Backup is one of the biggest challenges that customers need to address. EMC technologies and solutions help make backups easier to manage, non-disruptive, faster, and more cost-effective. Backup performance can be severely degraded due to server consolidation in a virtualized data center. Solutions such as EMC Replication Manager manage EMC point-in-time replication technologies through a centralized management console. Replication Manager coordinates the entire data replication process from discovery and configuration to the management of multiple application consistent disk-based replicas. You can also auto-discover your replication environment and enable streamlined management by scheduling, recording, and cataloging replica information, in addition to configuring auto-expiration. The EMC NetWorker Module for Microsoft Applications delivers a unified solution for protecting Microsoft server applications, including Exchange Server, SQL Server, Office SharePoint Server, Data Protection Manager, Hyper-V, and Active Directory. It enables EMC NetWorker to leverage the VSS framework for consistent point-in-time application snapshots and delivers quick recovery and off-host backup. This delivers time savings, less impact on the host CPU, and fewer burdens on the network. Recovery Source Clone copy with Replication Manager Tape Restore time Log playback time Recovery Time Minutes TIME Assumes snaps twice per day Multiple hours Figure 4: EMC Replication Manager reduces restoration time from hours to minutes Business continuity and disaster recovery For business continuity, EMC RecoverPoint provides an enterprise-scale solution designed to protect application data on heterogeneous SAN-attached servers and storage arrays. RecoverPoint runs on an out-of-band appliance and combines industry-leading, continuous data protection technology with a bandwidth-efficient, no-data-loss, continuous replication technology, enabling it to protect data both locally and remotely. With RecoverPoint, administrators can implement a single, unified solution to 10

11 protect and/or replicate data across heterogeneous storage with minimal to no data loss as compared to traditional host and array snapshots or disk-to-tape backup products. Administrators can simplify management and reduce costs, recover data at a local or remote site at any point in time, ensure continuous replication to a remote site without impacting performance, and ensure application and database recoverability and consistency in the event of a failure. The ability to enable rapid and consistent recovery is key for mission-critical application environments. Timely recovery of operations that have been disrupted because of a disaster situation is critical and necessitates solutions and expertise that ensures systems are brought back online in a sequential order based on levels of importance to the business. Additionally, virtualization now provides opportunities to deploy cost-effective business continuity and disaster recovery. Archiving Intelligent archiving enables you to gain a cost-effective, online archive for your organization s non-changing data assets so that you can minimize risk, control costs, and increase content reuse. Modern archiving solutions enable you to focus on active production information. You can apply common archiving services such as retention, distribution, and security across a variety of content types, while automating data movement to the most appropriate storage tier. The result is more secure archived data at the lowest total cost. 60 Reduce Production Storage Capacity Requirements 160 Improve Backup and Recovery Capacity Requirements (TB) Production capacity requirements without archiving Production capacity requirements after shortcutting and deletion Storage (GB) Year 1 Year 3 Year 5 0 Current Storage Archive Effect on Storage ROI/TCO with EMC SourceOne Management Free up your production storage for newest content Decelerate recurring production storage purchases and reclaim production capacity ROI/TCO with EMC SourceOne Management Substantially shorten time required for each full backup by shrinking production environment Equally important shorter backups lead to shorter recovery times Figure 5: EMC SourceOne Management reduces production storage requirements and improves backup and recovery performance EMC SourceOne Management for Microsoft Exchange is a next-generation archiving solution that helps you reduce operational costs while enforcing record-keeping policies in compliance with internal governance as well as with industry and government regulations. EMC SourceOne Management for Microsoft Exchange moves information that is no longer actively used so that production storage is freed for newer content, backup times are significantly shortened, the cost of the backup infrastructure is reduced, and fewer demands are made on the network. In addition, with EMC SourceOne Management for Microsoft Exchange, you can improve user productivity by providing seamless access to archived content. You gain proactive information management to help with litigation readiness, including a centralized archive to accelerate largevolume discovery searches and to enable secure legal hold. Additionally, you get the flexibility of a solution that scales to meet large enterprise needs yet that offers a simple footprint for midsize organizations. 11

12 Deduplication Data deduplication solutions identify and eliminate redundant data so that you store it only once. Data deduplication enables you to address the problem of exploding data growth and deduplicate at the right place production source or backup target and at the right time immediately or scheduled to achieve maximum back-end storage reduction and optimal performance. Sourcebased data deduplication is ideal for virtualization solutions, such as VMware vsphere, by reducing infrastructure impact. Policy-based target data deduplication provides the flexibility to deduplicate immediately at backup, to schedule deduplication for later to achieve maximum performance, or to turn-off deduplication for data that doesn t profile well. EMC Avamar backup and recovery solutions use patented global data deduplication technology to identify redundant data at the source, minimizing backup data before it is sent over the LAN/WAN. With Avamar, you can achieve new levels of data reduction and enable fast, secure backup for your virtual environments, remote offices, and data center LANs. You will reduce backup time, growth of secondary storage, and network utilization. Avamar-deduplicated backups function like full backups and can be recovered in just one step, without your restoring full backups and subsequent incrementals. In addition, Avamar verifies backup data recoverability and encrypts data for secure electronic backups. Retain. Replicate. Recover. Deduplicate everything without changing anything Simplify backup, archiving, and disaster recovery with easy integration across workloads, infrastructures, and backup software Never back up the same data twice Revolutionize your backup by moving less data to solve your toughest VMware, NAS, and remote office backup challenges Figure 6: Data Domain deduplicates exiting data while Avamar deduplicates data at the source Data Domain, an EMC company, provides deduplication storage systems that dramatically reduce the amount of disk storage that is needed to retain and protect enterprise data. By identifying redundant files and data as they are being stored, Data Domain systems provide a storage footprint that is from 10 to 30 times smaller, on average, than the original data set. Backup data can then be efficiently replicated and retrieved over existing networks for streamlined disaster recovery and consolidated tape operations. With Data Domain, you simplify backup, archiving, and disaster recovery with easy integration with your current workloads and current backup software and infrastructure. 12
