What energy efficiency metrics can be used by IT managers to measure and maintain the implementation of cost savings and green initiatives in data centers? This paper looks at the background of the problem and explores the reasons why energy savings in the data center is an important issue. Included are interviews and survey results from IT professionals serving at four unique organizations. A model of the measureable components of a data center is created to provide a framework for organizing metrics and communicating results throughout the corporation. The strengths and weaknesses of two of the most common data center metrics, PUE and DCP, are examined closely. Finally, the paper concludes with future metric recommendations and a proposed credit-based system that could be applied to encourage closer management of these metrics.
