  1. Green IT Focus: Server Virtualization

  2. Why Server Virtualization Matters • Reduces number of physical servers and total cost of ownership • Decreases Data Center space and cooling requirements • Saves an estimated 7000kWh of electricity annually per server, or about $700 in energy costs • Eliminates approximately 4 tons of CO2 for each server virtualized (equivalent to removing 1.5 cars from highway)

  3. Project Goals Initial proposal • Increased performance and scalability • Improved redundancy and disaster recovery • Reduced total cost of ownership • Simplified backups • Matched development/test/production platforms Added Green IT significant benefits • Reduced energy usage and physical footprint • Less heat generated, less cooling required

  4. Timeline and Key Milestones February 2006 Initial proposal developed August 2006 30 virtual servers deployed in main cluster October 2008 79 virtual servers in main cluster, total of 102 virtual servers in production

  5. Phase I Implementation Before After

  6. Before After

  7. Green Results • Current estimated net power savings: 23.4kW • Fewer physical servers in the Data Center results in less heat generated, less cooling costs, and less physical space required • Decreased costs for server related deliveries and disposal of packing materials & e-waste • Power utilities provide incentives based on net reduction in kW/hours to help offset capital investment

  8. Next Steps • Virtualized desktops • Blade servers for further power savings • Dynamic Power Management (ability to power off idle hosts) • Warm-site recovery • Virtual server hosting service for campus units
