Abstract
An operating state of each of a plurality of storage units of a storage system is periodically monitored, including a storage capacity, a throughput, and overlap of clients associated with the storage units. In response to a request to redistribute data from a first of the storage units to another storage unit, a cost factor for each of remaining storage units to relocate the data of the first storage unit to each of the remaining storage units is determined. A cost factor of each of the remaining storage units is determined based on at least one of the storage capacity, the throughput, or the overlap of clients of the storage unit. A second of the storage units having a lowest cost factor amongst the remaining storage units is selected. At least a portion of the data of the first storage unit is migrated to the second storage unit.
