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]
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.
[1] [2] To calculate simple WUE, a data center manager divides the annual site water usage in liters by the IT equipment energy usage in kilowatt hours (Kwh). Water usage includes water used for cooling, regulating humidity and producing electricity on-site. [ 3 ]
NEW YORK (Reuters) - U.S. data-center power demand could nearly triple in the next three years, and consume as much as 12% of the country's electricity, as the industry undergoes an artificial ...
In computing, performance per watt is a measure of the energy efficiency of a particular computer architecture or computer hardware.Literally, it measures the rate of computation that can be delivered by a computer for every watt of power consumed.
Energy Logic is a vendor-neutral approach to achieving energy efficiency in data centers.Developed and initially released in 2007, the Energy Logic efficiency model suggests ten holistic actions – encompassing IT equipment as well as traditional data center infrastructure – guided by the principles dictated by the "Cascade Effect."
