Computing device system and information managing method for rearrangement of data based on access characteristic related to a task

An information management method for a computing device system comprising at least one storage subsystem and a plurality of computing devices connected to the at least one storage subsystem, the at least one storage subsystem comprising:

• a plurality of physical storage devices of different response performances;
• a memory configured to store virtual logical volume management information associating a pool including actual storage areas of the plurality of physical storage devices with at least one virtual logical volume comprising the pool;
• and
• a processor configured to execute processing for assigning an actual storage area included in the at least one virtual logical volume for one of the plurality of computing devices,
• the information management method comprising:
• configuring, by at least one computing device of the plurality of computing devices, rearrangement reference information showing whether a characteristic of accesses counted with respect to each of a plurality of predetermined units is considered as a decision criterion for transfer destination determination in rearrangement processing of transferring data between the actual storage areas of the plurality of physical storage devices of the different response performances,
• referencing, by the processor, the rearrangement reference information, and
• executing, by the processor, rearrangement processing so as to transfer data stored in the actual storage areas to different actual storage areas in the plurality of physical storage devices of the different response performances, 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.
