摘要： One or more storage systems are connected to one or more storage boxes comprising multiple storage devices. Multiple storage areas provided by one or more storage boxes include an allocated area, which is a storage area that is allocated to a virtual volume, and an empty area, which is a storage area that is not allocated to any logical volume. Multiple owner rights corresponding to multiple storage areas are set in one or more storage systems. A storage system having an empty area owner right changes an empty area to the allocated area by allocating the empty area. In a case where a configuration change (a relative change in the number of storage boxes with respect to the number of storage systems) is performed, a first storage system that exists after the configuration change sets, in the first storage system, either more or fewer owner rights than the owner rights, which have been allocated to the first storage system before the configuration change.

摘要： A storage system manages correspondence relationships between physical addresses and logical addresses inside a storage device, as well as logical spaces provided by a plurality of storage devices, and when a determination is made as to whether first data and second data are stored in the same storage device in a case in which the first data and the second data are exchanged inside a logical space, and the determination is found to be affirmative, the storage device replaces the logical address corresponding to the first data with the logical address corresponding to the second data without changing the physical address of the physical area in which the first data is stored and the physical address of the physical area in which the second data is stored.
