Individual server behavior does not equal aggregate behavior
I recently had an email discussion with some colleagues regarding an interesting question: If server power use varies with utilization, why does UPS output in most data centers stay flat from hour to hour? Conventional wisdom says that the power … Continue reading

Is the datacenter just another department in energy terms?
Atlanta-based start-up JouleX seems to think so. I have just finished a report on the company which is trying to establish a lead in the field of Enterprise Energy Management (EEM). This emerging area of eco-efficient IT is characterized by … Continue reading

More uncertainty for datacenter operators over CRC
Whoever decided to put the word “commitment” into the title of the UK’s latest piece of environmental legislation must be kicking themselves for not having another noun to hand. Substituting “commitment” for the words “idea”, “proposal” or perhaps “thing-we-thought-up-but-might-not-actually-do” would … Continue reading

Successful GEIT Case Studies: Facilities Innovation
Facilities Innovation case studies document facilities-based projects that significantly and quantifiably improve data center energy efficiency. Because these projects are undertaken in a live data center with availability requirements, judicious planning, detailed monitoring, and careful documentation are fundamental to their … Continue reading
