The datacenter in Atlanta is located in Suwanee which is north of Atlanta. The Building is operated by Quality Technology Services (www.qualitytech.com). I know since they occupy half of the building. -- Brian Raaen Network Engineer On Wednesday 01 October 2008, Alex Ru

Google not counting electricity losses from power cords etc gives the image that it doesn't really want to account everything and want to skew the numbers as much as possible. I would be far more interested in a metric that shows the amount of power used for each MIPS of CPU power (or whatever CPU

Re: Google's PUE

I can't comment on the cost to a large data center, but I just finished renovating our small data center here in New York City by putting in a cogeneration system. We installed a natural gas microturbine, and are recapturing the waste heat to drive an absorption chiller. The rough rule of thu

RE: Google's PUE

I only quickly read this, but have the following question, should google like to answer it... Of the six datacenters, where are they all physically located? Someone should get on the bandwagon of having a PUE standard that is climate based. A PUE of 1.3 in the Caribbean is way impressive than 1.3
