● Resulting power draws per rack have grown eightfold since 1996
● Average (Peak) kW per rack• 2000: 1kW• 2006: 2-4kW• 2010: 6kW+
● Over 40% of data center customers report power demand outstripping supply
● Power density is increasing with new server form factors
● Power and cooling budgets have become difficult to predict …
● And the pace of technology continues unabated …

Virtualization myths
● Virtualization always increases efficiency
● I don’t need to worry about power and cooling when virtualizing
● High density and high efficiency cannot coexist
● Virtualization requires high density data centers

● UPS efficiency has large effect on data center efficiency because total IT load goes through it
● Improvement over typical from 80% to 96% efficiency at 20% load corresponds to loss reduction of 80%
● Electricity savings can pay for the UPS in many cases
● Side effect of high efficiency design: UPS is nearly silent

● Over half the power and cooling losses in a data center are fixed and do not vary with the IT load (so efficiency degrades as IT load declines)
● Oversizing is therefore a primary contributor to inefficiency
● Virtualization and server power management will make this problem worse, if power and cooling are sized to peak IT loads that are not typical
● New power and cooling devices can scale in capacity, reducing fixed losses

● Poor utilization of capacity is a primary cause of inefficiency
● Software can identify available capacity (even by rack) and help prevent creation of stranded capacity
● Side effect is you can fit more IT equipment in the power and cooling “envelope” of the data center
● Energy management can identify efficiency improvement opportunities
