Global metric for data center efficiency adopted

The EU, U.S., Japan, and the Green Grid industry group are using PUE, or power-usage effectiveness, as the metric for gauging and comparing energy use.

IT professionals are set to benefit from the use of a single metric to measure data center efficiency, after organizations from Europe, Japan, and the U.S. agreed to work together on a global framework.

The agreement, announced Tuesday, was reached by the EU Code of Conduct, the U.S. Department of Energy and Environmental Protection Agency, and Japan's Ministry of Economy, Trade and Industry, along with the Green Grid--a data center industry consortium that includes heavyweights like Hewlett-Packard, Dell, Intel, and Microsoft.

"The ultimate goal is to create a set of globally accepted metrics for data center energy efficiency," said Tom Brey, secretary of the Green Grid, in a statement.
