I notice with great interest that power is starting to push its way to the front of the agenda when discussing any projects these days. While at Tech.Ed this year we were told that Microsoft are building a large DC in Ireland "because of ambient air temperature" Its cold most of the time
. I didn’t appreciate what this meant until I read the article below which suggests allowing your DC to run at a balmy 32 C (much like any married man’s living room *

At that rate, the United States will need 30 new 1,000-megawatt power plants by 2015 just to support data center usage."
