EPA Preps Energy Star Server Spec

The Environmental Protection Agency is moving closer to finalizing an Energy Star efficiency rating for servers, which will help data center managers compare energy usage among vendors. The EPA has completed the third draft of its spec for Energy Star server ratings, and Mark Fontecchio at Server Farming has details.

“The spec includes a matrix for power supply efficiency requirements,” Mark writes. “For example, if the server has a multi-output power supply, the supply should be at 82% efficiency when the server is at full load. The spec also sets power consumption limits for when the server is idle. For a single-socket server, the limit is 60 watts; for 2-3 socket servers, the limit is 151-221 watts depending on how much memory is installed; and for four-socket servers, the limit is 271 watts.”
