2 Agenda Introduction Company Profile Imperial Parking Before Virtualization The Challenge, Drivers & Requirements The Solution Design & Benefits Disaster Recovery Failover Procedure & Summary Achieved Virtualization, Results & Summary Q&A

3 Introduction Presenters Mike Gower - I.T. Blueprint Solutions Consulting Inc. Chris Fraser - Long View Systems Topic Server consolidation and business continuity using VMware ESX and Network Appliance (NetApp) SnapMirror technology

4 Company Profile Imperial Parking Corporation Full suite of parking and transportation services to a wide variety of clients across North America Statistics 35 offices, 1,800 parking facilities, 425,000 spaces in Canada and the United States and 3,700 employees Web URL

5 Environment Before Virtualization 38 physical servers NT 4.0 & 2003 Active Directory mixed infrastructure. SQL, Oracle, Exchange, Citrix, Great Plains, and custom LOB Apps User requirements Business Continuity Support new company initiatives Limitations Success by heroic effort Complex environment Lack of Documentation Development environment

6 The Challenge Mix of Hardware The Desktop server Specialty servers Old hardware Recoverability New projects Need to support new corporate initiatives Mixed environment and unfinished migrations/projects Both NT 4 and 2003 AD Power and Cooling Consumption and Cooling in current Data Center at capacity

7 Key Drivers and Requirements Support growth New projects Corporate growth Reliable and Agile technology Manageability Time to implement new systems Governance model Revitalization of technology New infrastructure vs. using existing Business continuity Ability to recover all specified systems!

8 The Solution Selection of Partner Long View Systems Technology Selection VMware ESX HP Proliant Servers Network Appliance Storage Implementation Provision new systems P2V existing systems Systems Management Vendor Support

9 Why Long View Systems? Local presence Vancouver and Calgary Ability to support Impark operations continentally Offices also located in Edmonton, Denver and Houston North American coverage through VTN Expertise in products selected VAC & Premier VIP Enterprise Partner 30+ VCPs on staff NetApp Platinum Partner HP Platinum Partner Storage Management & Server Consolidation are 2 of our 8 core practices Our culture of flexibility and a get it done attitude Our people

10 Servers & Software Virtual Infrastructure Starter Kit consisting 4 VIN nodes, Virtual Center & P2V starter kit. (Starter Kits no longer available) ESX Servers: 4 HP Proliant DL585s, each with 4-way AMD Opteron 2.4 GHz Dual Core processors & 32 GB PC3200 SDRAM, 8 NIC ports, 2 Qlogic HBAs Virtual Center Server: HP Proliant DL385, 2 way AMD Opteron 2.4 GHz Dual Core processor & 4 GB PC3200 SDRAM

11 Storage Technologies Storage Network Appliance 3020HA storage configured with initial 2TB of storage with SnapMirror license HP StorageWorks (Backup) Snapshots Network Appliance Snapshot technology Replication NetApp SnapMirror Integrated feature that provides automated file system or LUN replication of a volume onto a remote filer

12 High Level Infrastructure Design

13 Additional Solution Components Management tools HP Systems Insight Manager HP SNMP Agents & HP Advanced ilo (Lights-out) Altiris Server and Infrastructure Management solution Governance Model Introduction of governance model for Service Delivery and Service Support based on ITIL Co-Location site Implementation of a warm lights-out co-location environment

14 Consolidation Approach Complete infrastructure refresh New virtual machines created for all key systems P2V migration of high risk or legacy systems

15 Design Category Assignment Servers and Storage designated into a service level category (Gold, Silver, Bronze) Gold and Silver: Each VM is configured with its own Flex Volume Separate VMDKs created for Operating System and Data drives VM Operating System Drive C VMDK App and Data Drive E VMDK Special Case Transactional Databases use an RDM and use an NTFS native format for the Data Drive instead of a VMDK file Bronze Shares common Flex Volume and LUN

16 Design Benefits Granular Control Flexible Failover Single VM or entire Data Center Minimal Impart to Environment Only changes replicated across WAN Future Considerations Maximize Disk Storage

20 Network Topology

21 Disaster Recovery Failover Procedure Using VMware and Network Appliance SnapMirror technologies Demo of procedures to recover a single failed server to the Disaster Recovery site

22 Disaster Recovery Summary Solution: Calgary setup as warm site Calgary configured as a separate network. Required routing added to allow all locations to access co-location network Calgary DNS server setup to act as a tertiary DNS server All branches DHCP scopes setup to include Calgary DNS server All branches VPN devices configured with 2 nd VPN tunnel to Calgary All replicated VMs have static MAC addresses DHCP MAC reservations used When a VM comes up in Calgary, DNS is updated for clients Assumptions: - All locations use DNS for name resolution (Not I.P. Addresses) - No hard-coding of server I.P. information in applications

23 Achieved Virtualization Virtual Environment (Production) 23 virtual servers (not included Development) Migrated services of 6 physical servers onto new core VMs P2V d 9 physical servers 30+ virtual machines considered direct hardware replacements ($370K Cost avoidance) Production virtual infrastructure running: NT 4.0 & Windows 2000 (de-commissioning) Windows File & Print, IIS, SQL, Oracle, DCs & Line of business applications, Citrix

24 Virtual Infrastructure 3 Early Q107 pilot HA & upgrade VC Late Q107 Migrate to VI3

25 Summary: Imperial Parking Key Benefits $480,000+ in avoided costs and/or savings ROI Year 1 Server Hardware Consolidation Business Continuity implemented Management and governance of systems Standardization of systems and processes Support new initiatives Full potential of savings yet to be realized By virtualizing unsupported infrastructure, we ve added a component of recoverability that we previously did not have.
