The bad news
Demand is up Price is up Oversupply is running out
The good news
Hardware manufacturers (finally) realise power is an issue
Energy policy high on government’s agenda IFL opening a new data centre
Demand is up
Demand is up
Average power per rack increasing Higher power servers Higher density deployments
High usage increasing faster Blade servers

Power challenges
Available supply Limits on supply from grid Delay on increasing supply
Cooling the data centre Chilled air has maximum capacity Increasing use of water cooled racks
Price is up

Hardware manufacturers respond
HP
“Server and data center power management: Our work proposed temperature-aware scheduling, hardware-software co-ordination to enforce power budgets, and new blade designs for lower power. Our optimizations are individually successful in reducing system power by 20-50%.”
IBM
“The need for more performance from computer equipment in data centers has driven the power consumed to levels that are straining thermal management in the centers.”
Sun Microsystems
AMD
Intel
“Silicon and Platform Innovation—New materials, manufacturing techniques, and architectural approaches (such as multicore processors) will deliver substantial improvements in performance per watt over the next few years. This will enable ongoing increases in datacenter compute density, without driving up power and thermal requirements.”
Government energy policy
Why are electricity prices so high?
Generating capacity shortfall of 7-16GW by 2015
Equivalent to about 20% of current capacity Uncertainty about security of supply
Government agenda
Energy review due by end of July Nuclear power “back on the agenda with a
vengeance” (Tony Blair, 16th May 2006)
Possible price review
OFGEM consulted the market regarding price review
Initial decision that review not justified (but not ruled out)
Commitment to work with business to resolve issue
New data centre
Reynolds House
Additional 13,000 sq ft (gross) 2 MW power 200 watts / sq ft Average 15 – 20 Amps / rack (3.5 – 4.5 kW)
