Data Center Energy Productivity (DCeP) - The New Metric on the Data Center Block

Posted on April 21, 2014 by Paula Alves

Improving energy efficiency has continually challenged data center managers over the past decade. At the heart of the matter lies the ongoing debate as to what exactly is the best metric or combination of metrics by which to monitor performance and make improvements.

Up until now Power Usage Effectiveness (PUE) has been the most common metric used. However, PUE has inherent limitations that the industry has attempted to overcome by introducing new metrics such as Green Energy Coefficient (GEC), Energy Reuse Factor (ERF), and Carbon Usage Effectiveness (CUE).
