摘要： Multiple storage area groups into which multiple storage areas provided by multiple storage devices are classified with reference to storage area attributes are managed. The multiple logical volumes to which, in accordance with a write request to at least one address included in multiple addresses in the logical volume, at least one storage area included in the multiple storage areas is allocated are provided. In accordance with the access condition of the at least one address in the logical volume, the data written to the at least one address by the write request is migrated from the at least one storage area included in one of the multiple storage area groups to at least one storage area in another storage area group included in the multiple storage area groups.

摘要： A virtual storage system is equipped with a plurality of storage systems and a virtualization device for virtualizing the plurality of storage systems logically into a single storage resource provided to a host computer. When one of the storage systems receives a command from the host computer, in the event that the storage system itself is not in possession of a function corresponding to the command, the storage system retrieves a storage system in possession of a function corresponding to the command and transfers this command to the storage system in possession of the function corresponding to the command.

摘要： A computer system dynamically assigns the storage capacity from pool volumes to the access target in the higher-level system, and can immediately respond to the change of the status of the pool comprising the pool volumes. A control device sets the access target for the host computer to access, each time a write to the access target occurs from the host computer, from the pool assigned to the access target to the write area of the access target. The control device performs the processing of assigning the storage capacity from the logical volume in the pool. The control device defines the logical volumes in advance, compiles the same into a management group as a preliminary for the pool and, in accordance with the change of the pool status, adds the logical volumes from the management group to the pool.

摘要： The present invention allocates a suitable physical device to each volume page according to the state transition command relating to paired volumes. A plurality of logical devices forming a logical storage area of a plurality of physical devices of varying performance are tiered according to the performance of the physical devices to form a pool volume, and each of the areas of the primary logical volume, secondary logical volume and pool volume are managed by a controller, divided into a primary page, secondary page and pool page. Upon receiving a pair formation-related command from the host computer, the controller allocates pool pages belonging to the same tier to the primary page and secondary page, and upon subsequently receiving a pair-related state transition command, the controller allocates a pool page, in a different tier from the primary page, to the secondary page.
