  1. IT Consolidation and Virtualization L A Technology Forum September 25, 2008

  2. What problems will virtualization address? • Contains operational sprawl by consolidating onto fewer but more powerful physical systems • Substantially decreases space, power, HVAC, and network requirements for the existing and new Data Center • Eases Disaster Recovery and Business Continuity by taking advantage of the virtual infrastructure hardware independence and application portability • Improves adaptability and responsiveness to customer requests by leveraging existing physical platforms • Changes the service delivery model from departmental to enterprise

  3. Wintel server growth projection - 2010 Consolidation ratio of 25:1 on Quad processor servers 5% Physical Servers 95% Virtualized Servers

  4. Data Center space projection • Assumptions: • Server growth of 100 servers per year: • 2006 – 2007 where 25% are physical and 75% virtual • 2007 – 2008 where 15% are physical and 85% virtual • 2008 – 2010 where 5% are physical and 95% virtual

  5. Data Center power projection

  7. Where are we today? • Deployed VMWARE ESX 3 infrastructure at both Downey and Orange County Data Centers • Established virtualization as the primary form of Wintel server hosting • Deployed over 400 virtual servers into production across both Data Centers • Shut down approximately 200 physical servers which equates to: • Space: Approximately 10 racks worth of servers • Electricity: 70 kVA = $103,883 per year • Cooling: 263,463 BTUs = $114,590 per year • Overall savings = $218,473 per year • Enabled automatic intra-Data Center failover • Created and tested manual DR failover for inter-Data Center failover • 8 VMWARE ESX clusters • 48 HP DL585 servers • 192 processors • 3072 GB memory • 34 TB EMC usable storage

  8. What applications have we virtualized? Web Servers – IIS/Cold Fusion, OAS, Tomcat, Apache Database – SQL, Oracle, Access Exchange – OWA, Exchange 2003 Security – AV Portals, PatchLink, Cisco Security Agent Active Directory Microsoft Softgrid Citrix XenApp 4.5 DNS, Network Management GIS Servers Learning Management Systems (LMS) And many more…

  9. Challenges encountered along the way… • Underestimated the resources required for planning and administrative support • One dedicated migration team (customer coordinator, migration admin, system/network admin) can execute about 20 migrations per week • “Hot” migrations did not work as advertised, requiring application shutdown and extended unanticipated outages • Pre-migration checklist was not fully developed during planning • Underestimated the time required to coordinate and receive customer approvals • Customer resistance primarily due to the lack of understanding of virtualization concepts • Better management of customer expectations is needed with ongoing communication • Insufficient SAN disk space

  10. Virtualization goals for 2008-09 • Virtualization of 25% of the remaining Wintel physical servers • Virtualization of Data Center network components • Unified IP – Storage network infrastructure • Virtualization of desktop services • Implement a virtual desktop delivery infrastructure • Implement a virtual application delivery infrastructure • Implement thin client desktops • Storage virtualization • “Thin” storage provisioning
