New Energy Productivity Metric Unveiled by The Green Grid
In the past, I’ve written about Power Usage Efficiency (PUE) as a benchmark for measurement in data centers. I have also pointed you to the Green Grid as a major industry resource for data center information. In an article featured on DataCenterKnowledge.com there is exciting new information that the Green Grid, along with a global task force, has standardized on a new equation that quantifies “useful work” produced by a data center based on the amount of energy it consumes.
Data Center energy Productivity (DCeP) has been in development since 2009. Simply, it is computed as (useful work consumed) / (total energy consumed), and the computation allows each user to define useful work as it is applicable to their own business. An example given by the Green Grid is that a retail business may use number of sales, while an online search company might use the number of completed searches as their measurement for useful work.
