Where Does the Power Go?

Compute resources and particularly servers are at the heart of a complex, evolving system!

2

x86 Servers are Driving Power Consumption

Servers = 40% of total data center electricity use and primary driver of remaining consumption

Volume servers = 85% of all server electricity use

Up from 70% in 2000 at 17% CAGR

Start by solving the problem “upstream” at the source!

Reduce Costs and Power Consumption

For every server virtualized, save…

~$700 and ~7,000 kWh / year $300 in carbon offsets over lifetime

4 tons of CO2 emissions / year

10:1 consolidation = 80-90% less energy

Plus Power down underutilized physical servers, saving 40% Desktop management reduces PC power usage 35% / year

Reduce energy costs by 80% Power down servers without affecting applications or users

Green your datacenter while decreasing costs and improving service levels

Example of Savings and Environmental Impact Virtualize 100 servers and …

• Save $661,899 in annual Server & cooling energy usage (kWh) • Save $525,00 in Physical Hardware & $66,189 in Annual energy Cost • These savings are equivalent to:

• Planting 2,000 trees • Taking 150 cars off the highway • Annual CO2 Emission (lbs/kg) 887,607 lbs & 402,612 kg
