Data center infrastructure efficiency (DCIE) is a metric that is used for determining the energy efficiency of a data center unit. This metric is articulated as a percentage and is calculated by dividing IT equipment power by total facility power. The concept of DCIE was refined by members of the Green Grid, a well recognized industry group focusing on data center energy efficiency. With the help of this tool, one can estimate the amount of power that is being consumed by data center for further analysis.
