Enterprise IT Planet’s Green blog has a post up this morning about an international agreement reached over the weekend that may help build momentum for a common vocabulary when it comes to measuring datacenter efficiency
Over the weekend, news emerged of an international agreement to establish data center energy efficiency. The agreement is between The Green Grid (U.S.-based industry group), the U.S. Environmental Protection Agency, the European Commission Joint Research Centre, the Japan Ministry of Economy, Trade and Industry, and the Green IT Promotion Council (Japan-based industry group). For now the agreement is limited to these three regions, but could expand to include others such as China and India in the future.
The agreement establishes the Power Usage Effectiveness (PUE) as the “preferred energy efficiency metric.”
Included in the agreement is a set of guiding principles, but notably missing are rules about how total energy should be measured. According to the post, a task force is working on these details.
