Abstract
In a storage system including plural source storage devices, a target storage device selects which source storage device to accept a copy request from the target storage device so as to minimize the load on the entire system. The system calculates first and second load values for job loads being processed. System load values for the system are derived from job load value of a specific data, and respective load values for first and second source storage devices. The system compares the system load values to select a storage device to provide the data copy so as to minimize the load on the entire system.
