Abstract
In a shared storage system for supporting virtual machines, virtual machine images are opportunistically migrated between logical storage units to free up physical storage units and achieve better storage hardware resource utilization and reduced power consumption by powering down freed-up physical storage units. The destination for the opportunistic migration of a virtual machine is selected based on the extent to which the physical storage units are shared between the logical storage unit in which the virtual image is currently stored and the destination. In situations where the demand for storage hardware resources increases, the powered-down physical storage units may be opportunistically powered up to meet the increased demand.
