Abstract:
1. A method of correlating power in a data center, comprising: supplying power to a portion of a data center through a power distribution line, the portion of the data center including a plurality of computers that draw power through a circuit breaker; monitoring CPU utilization of a statistical sample of the plurality of computers, the statistical sample being a statistically significant number of the plurality of computers that is less than all of the plurality of computers; calculating an estimated individual power draw for each of the statistical sample of the plurality of computers based on the utilization; calculating an estimated total power draw for each of a plurality of different times from the estimated individual power draw of each of the statistical sample of the plurality of computers to generate a plurality of estimated total power draw values for the plurality of different times; monitoring actual power draw at the power distribution line by the portion of the data center and generating a plurality of actual power draw values for the plurality of different times; fitting a function to a plurality of pairs of actual power draw values and estimated power draw values, each pair of the plurality of pairs comprising an actual draw value and an estimated draw value for the same time; and storing the function.
