3. Why Virtualization? Business Benefits for Hennepin County Slows physical growth in the Data Center facilities; with the rate of the server farm growing 60% per year, the Data Center would be out of floor space by 2011 Replaces many, underutilized servers with fewer, more powerful servers Lowers hardware, software and datacenter costs. A VM is approximately Half the monthly cost of a physical server! In 2007 EITS saved nearly $1,000,000 in defered hardware purchasing alone, due to virtualization! Provides a scalable server solution to meet variable business demands Improves server “time to deployment” from approximately two months to less than a week Provides the foundational technology for disaster recovery/business continuity for Windows-based applications

4. Virtualization Project Stages Design, Plan, Document – July ‘06 Pilot “Go Live”- Nov. 2006 –ESX 2.5 three node cluster –VC 1.5 Production Deployment – Feb. 2007 –ESX 3.0 two new three node clusters –VC 2.0

5. Rack Space Comparison 120 physical servers = 4 - 8 servers per rack fully using at least 20 racks 120 virtual servers on 6 Hosts = 3 servers per rack over 3 racks (and there’s still room in the racks for more servers) =

7. Current VI3 Environment 10 VI3 Hosts at Primary Data Center 6 - Hosts for Production Servers 4 - SUSE Linux Vignette Web Portal 10 VI3 Hosts at Secondary Data Center 3 - Hosts for Production Servers 3 - Hosts for Windows Test and Dev Servers 4 - SUSE Linux Vignette Web Portal

8. Hardware HP Proliant DL 585 G2’s (Sorry DELL!) –4 dual core CPU’s –32 GB –Local drives –SAN Attached – IBM DS 8100

9. Networking

13. SAN Design 2.4 TB

14. Default VM Settings Memory: 512 MB C: drive: 9 GB (soon to be 12GB) D: drive: 10 - 50 GB [upon request; RDM] CD/ISO: Common file ISO repository – “VMISO” LUN Presented to all VI3 hosts. VM Template Update Frequency: Quarterly

15. Resource Pools PreProd Development Production – Standard Production - High

16. HJIP – IBM MQ Series Brokers and Websphere App Servers Internet web portal presence - Vignette (SUSE Linux) 180+ VM Servers and growing 20 to 1 or higher Consolidation Ratio Goal Server Virtualization is now offered as a Production Enterprise Service What is Currently Virtualized?

17. Overcoming the stigma – Not for just testing anymore Network design limitations – No L2 –No Site to Site VMotion - Yet Backup and Recovery of image files requires large amounts of SAN storage Everyone wants their own virtual environment! Policies and procedures defined and in place Licensing applications per CPU Virtual Challenges?

18. Virtual successes 135 days of uptime Acceptance of Virtualization in Production OpsMgr 2007 100% virtual SQL Server 2005 virtualized No experience (or consultants) necessary!

19. Next Generation: Upgrade to VC 2.5/ VI 3.5 – 4 HP DL585 G5 w/64 GB, 4 quad core. 3 more clusters planned this year Site-to-Site Recovery for DR/BC Bidirectional SAN mirror replication Integrated Patching of Hosts and VM’s Virtualize DMZ Virtual Appliances – Started APEX – Virtualize PeopleSoft and Oracle Test/Dev implementation PowerShell – Automation of Adminstration What’s in the Future?
