  1. Hennepin County Central IT Enterprise Virtualization Services (EVS) October 01, 2008 - VMUG Michael T. Brown Hennepin County Enterprise Virtualization Administrator

  2. Virtualization Team VI ESX Host Team • Val Ross – Team Supervisor and Virtualization Program Manager • Michael Brown - VI Administrator • Robert Backer - VI Administrator Backup • Chris Gaasch – Network and SAN Architect • Rick McLagan - QA and Resource Management • Becki McDonald - Project Manager VM AdminTeam • Robert Backer, Reg Giacomini - VM Deployment and Configuration • Bob Lerner - VM Imaging and template design • Jerry Stenberg - VM Security Management Support • Larry Ingram – Manager (approves purchases and signs the checks!) • Val Ross -VM Gatekeeper All requests for VM’s go through the server request system. Customers HSPHD, Public Defender’s Office, EHD – Remedy, Taxpayer Services, Public Works, MHP, IT Development, Enterprise IT Services and YOU!

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

  6. 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

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

  8. Networking

  9. SAN Design 2.4 TB

  10. 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

  11. Resource Pools • PreProd • Development • Production – Standard • Production - High

  12. What is Currently Virtualized? • 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

  13. Virtual Challenges? • 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

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

  15. What’s in the Future? • 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
