ABSTRACT:
A host computer requests a storage device to perform a data transfer operation using information about the data transfer source/destination regions as a parameter. The storage device internally transfers data from a source disk device to a destination disk device. When the transfer of the data is completed, the storage device notifies the host computer that the operation has been completed. The host computer receives the notification and updates the storage location of the data to the destination region.
