Data center infrastructure efficiency (DCIE) is the reciprocal of PUE and is expressed as a percentage that improves as it approaches 100%. How to Determine PUE1. Take a measurement of energy use at or near the facility's utility meter. If the data center is in a mixed-use facility or office building, take a measurement only at the meter that is powering the data center. If it is not on a separate utility meter, estimate the amount of power being consumed by the non-data center portion of the building and remove it from the equation. 2. Measure the … Power Usage Effectiveness (PUE) definition sponsored by SearchDataCenter.com, powered by WhatIs.com an online computer dictionary
