Facebook takes on Mother Nature by using open air cooling for N.C. data center

Facebook's data center in North Carolina.Facebook has managed to make its newest data center in North Carolina more efficient than the one it built in Prineville, Ore., despite the sweltering heat of the Carolina summer. By using open-air cooling and its Open Compute Foundation servers, Facebook has achieved a PUE score of 1.07 (the Prineville facility has a PUE of 1.09). PUE, or power usage effectiveness, is a metric that divides how much energy a data center uses in total by how much its IT equipment uses, and the closer you are to one the more efficient your data center is.
