Patent ID: 8645655

Claim:
A computing device system comprising at least one storage subsystem and a plurality of computing devices connected to the storage subsystem, wherein the storage subsystem comprises: a plurality of physical storage devices of different response performance; a memory storing virtual logical volume management information associating a pool including actual storage areas of the physical storage devices with at least one virtual logical volume comprising the pool; and a processor which executes processing of assigning an actual storage area included in the virtual logical volume to one of the plurality of computing devices, wherein at least one computing device of the plurality of computing devices configures rearrangement reference information showing whether an access characteristic related to a task executed on the plurality of computing devices is considered as a decision criterion for transfer destination determination in rearrangement processing of transferring data between the actual storage areas of the physical storage devices of different response performance, and wherein the processor of the storage subsystem refers to the rearrangement reference information and, based on an access characteristic of the plurality of computing devices with respect to the actual storage areas assigned to the plurality of computing devices, executes rearrangement processing of transferring data stored in the actual storage areas to different actual storage areas in the physical storage devices of different response performance.
