摘要：
A mechanism, in a data processing system, is provided for logical partition defragmentation. The mechanism gathers resource requirements for a plurality of logical partitions running in a plurality of power domains within one or more servers. The mechanism determines optimal hardware utilization for the plurality of logical partitions. The mechanism migrates one or more of the plurality of logical partitions to run in a subset of the plurality of power domains such that at least one power domain within the plurality of power domains is unused. The mechanism puts the at least one unused power domain in a low power state.
