3. Green IT and VITA Transformation Efforts • Data Centers are huge CO2 factories • 1 full rack of blade servers = 20-25 kW = peak demand of 30 homes in California • U.S. data centers = 45 billion kWh, 1.5% of total consumption* • This electricity use has more than doubled since 2000 • Every server removed or powered down saves ~12.5 tons of CO2 emissions • Equivalent to taking ~1.5 cars off the road (12,000 miles @ 20 mpg) or planting 55 trees a year * EPA report to Congress on Data Center Energy Efficiency, July 2007 What is VITA doing…….

4. VITA IT Transformation - Energy Savings How Transformation Contributes to Energy and Environmental Savings • Provide energy efficient technology and products for the Commonwealth such as ENERGY STAR qualified computers, printers and monitors • Reduce the costs of power and cooling through the consolidation and virtualization of the IT server infrastructure • Promote environmental improvement by increasing levels of efficiency that ultimately reduce greenhouse gas emissions • Promote teleworking initiatives to save on energy and emissions • Audit compliance with “green” or “emissions” objectives, regulation and standards • Work toward establishing an enterprise-wide awareness to staff the expected power management settings requirements and best practices for energy conservation - Ensure that everyone understands their personal responsibility to do so

5. Server Consolidation through Virtualization – Energy Savings Reduce the costs of power and cooling through the consolidation and virtualization of the IT server infrastructure • While servers operate primarily in a 24/7 active mode state, consumption efficiencies are best gained through workload consolidation and server virtualization efforts • For approximately 344 physical servers that have been consolidated through virtualization and based on an actual physical to virtual ritual ratio at that point in time, EnergyStar based estimations using the U.S. EPA and U.S. DOE energy savings calculator yield an anticipated annual cost savings of 83K. VMWare estimations for energy cost savings • A single server can provide as may as 200 virtual servers using VMware. • A virtualized server providing 100 virtual servers uses 16% the power of the 100 servers and reduces the heat generated accordingly. • Virtualizing 100 servers reduces annual energy costs by $525K. • Assumptions: $6500 & 550 watts/ 2 cpu server; $0.10/KWH; 12000 miles/yr; 20mpg; 1,341 # CO2 / KWH.

10. Worldwide Server Market: Cost of Management Ramps Dramatically Worldwide IT Spending on Servers, Power and Cooling, and Management/Administration (US$B) Physical Server Installed Base (Millions) Many Servers, Much Capacity, Low Utilization = $140B unutilized server assets We Spend $0.50 in Power & Cooling For Every $1.00 in Hardware

11. HP delivers profit/watt, not just performance/watt Scaling IT faster than cost with c-Class, IPM & Thermal Logic versus 50% more servers 25% lower airflow 50% more servers 26% drop in Temp 50% more servers 37% less power Source: HP, C. Bash, W. Vinson, 2006
