So the actual claim is that 90% of the power is wasted. Add the specifier "as heat" implies (to me) that the other 10% is converted into something other than heat. 100% of the power in a data center turns into heat. The question ultimiately is how much of that energy consumption could be avoided while accomplishing the descired task. -- Grant Edwards grant.b.edwards Yow!
