Joyent Tools Cut Data Center Power Consumption

September 20th, 2012

New tools are appearing in the ongoing battle to reduce energy consumption in a data center, and some of these tools are also designed to boost a data center's power usage effectiveness (PUE) rating. Google, Facebook, Yahoo, and Microsoft compete to get to the lowest possible PUE measure in their newest data centers.

PUE compares how much total electricity a data center imports to get a unit of computing done. Most older enterprise data centers have a PUE of 1.9- 2.0; they consume almost twice as much power as what's actually devoted to computing. The extra power is needed for heating/cooling, lights, and auxiliary systems, with cooling being the biggest culprit.
