ABSTRACT:
A method of managing data center power usage based on service commitments. A power and capacity management utility measures performance characteristics of applications hosted by a data center that include power consumption and transaction processing time. When the performance characteristics are above (or below) a first pre-defined target range, the utility decreases (or increases, respectively) a clock rate and processor voltage of one or more active servers. When the performance characteristics are within the first target range and the clock speed is above (or below) a second pre-defined target range, the utility activates (or deactivates, respectively) one or more inactive (or active, respectively) servers. When the size of an inactive server pool is above a third pre-defined target range, the utility moves inactive servers to an unallocated server pool. When the size of the inactive server pool is below the third target range, the utility allocates additional servers.
