Power usage effectiveness
Encyclopedia
Power usage effectiveness (PUE) is a measure of how efficiently a computer data center
uses its power; specifically, how much of the power is actually used by the computing equipment (in contrast to cooling and other overhead).
PUE is the ratio of total amount of power used by a computer data center
facility to the power
delivered to computing equipment.
PUE was developed by a consortium called The Green Grid
. PUE is the inverse of data center infrastructure efficiency
(DCiE). An ideal PUE is 1.0. Anything that isn't considered a computing device in a data center (i.e. lighting, cooling, etc.) falls into the category of facility power usage.
