Got a copy of the Cassatt Energy Efficiency Survey. Highlights are as follows:

From the responses we received from IT professionals and facilities managers we learned several interesting facts:
63% of you are either working on a data center energy-efficiency project now or expect to within the next year
43% of you have a data center that is within 25% of its maximum power capacity
61% of you are aware that the EPA recommends turning off idle servers to save energy, but over 30% say you don’t know how many servers are idle at any given time
Server power management software is the energy saving strategy that large companies selected most frequently as their next step for the future (29%)
