As of the end of Q2 2015, Facebook's Prineville data center had a power usage effectiveness (PUE) of 1.078 and its Forest City data center had a PUE of 1.082. [15] In October 2015, Allied Control has a claimed PUE ratio of 1.02 [16] through the use of two-phase immersion cooling using 3M Novec 7100 fluid.
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]
A clothes dryer using a demand response switch to reduce peak demand Daily load diagram; Blue shows real load usage and green shows ideal load.. Demand response is a change in the power consumption of an electric utility customer to better match the demand for power with the supply. [1]
The power measurement is often the average power used while running the benchmark, but other measures of power usage may be employed (e.g. peak power, idle power). For example, the early UNIVAC I computer performed approximately 0.015 operations per watt-second (performing 1,905 operations per second (OPS), while consuming 125 kW).
