  2. Power usage effectiveness - Wikipedia

    en.wikipedia.org/wiki/Power_usage_effectiveness

    Accuracy in the IT load is one of the major factors affecting the measurement of the PUE metric, as utilization of the servers has an important effect on IT energy consumption and hence the overall PUE value". [10] For example, a data center with high PUE value and high server utilization could be more efficient than a data center with low PUE ...

    PUE measures the percentage of power used by overhead devices (cooling, lighting, etc.). The average USA data center has a PUE of 2.0, [86] meaning two watts of total power (overhead + IT equipment) for every watt delivered to IT equipment. State-of-the-art data centers are estimated to have a PUE of roughly 1.2. [87]

    It is an addition to the power usage effectiveness (PUE) definition and was first proposed by Greenqloud. [1] The Green Grid has developed the Power Usage Effectiveness metric [2] or PUE to measure a data centers' effectiveness of getting power to IT equipment. What the PUE tells in simple terms is how much extra energy is needed for each ...

    Data center infrastructure efficiency (DCIE), is a performance improvement metric used to calculate the energy efficiency of a data center. DCIE is the percentage value derived, by dividing information technology equipment power by total facility power. [1] [2] [3]

    The best PUE a data center can have is 1: an ideal situation, with no extra energy use. When PUE was introduced, studies found that the industry-average PUE was between 2.5 and 3. In more recent studies, the average PUE fell to about 1.7 by using this framework. PUE began the shift of the data-center industry towards energy efficiency. [5]
