    摘要: A storage system comprises a virtual volume configured of multiple virtual areas and a pool configured of multiple actual area groups of different performances. The controller of the storage system manages which actual areas are assigned to which virtual areas and the access load on the actual areas assigned to the virtual areas. The controller, if the access load of a first actual area assigned to a first virtual area is inappropriate for a first actual area group comprising the first actual area, migrates data to a second actual area in a second actual area group which is appropriate for the access load of the first actual area from the first actual area. The controller performs data migration between actual areas for achieving data allocation at a certain point of time based on history information which is the information related to a virtual area at a point of time in the past and an actual area assigned to the virtual area. Data allocation is the allocation of data in a virtual area to an actual area in an actual area group.

    摘要: A first virtual storage and a second virtual storage share an external LU (Logical Unit) inside an external storage. The first virtual storage comprises a first LU, which comprises multiple first virtual areas and conforms to thin provisioning, and an external capacity pool, which is a storage area based on the external LU, and which is partitioned into multiple external pages, which are sub-storage areas. The second virtual storage comprises a second LU, which comprises multiple second virtual areas and conforms to thin provisioning. In a data migration from the first LU to the second LU, for a data migration from a first virtual area, to which an external page has been allocated, to a second virtual area, the first virtual storage notifies the second virtual storage of a migration-source address, which is an address of the first virtual area, and an external address, which is an address of the external page that has been allocated to this virtual area, and the second virtual storage stores a corresponding relationship between the notified migration-source address and external address.

    摘要: The present invention efficiently changes a volume size while maintaining a copy pair as-is. A PVOL and a SVOL #1 are in a pair state and are synchronized. The PVOL and a SVOL #2 are in a restore state. Upon instruction of expansion of the size of the PVOL, the size of a copy-destination SVOL #1 is first expanded, the size of the PVOL is then expanded, and the size of the SVOL #2 is lastly expanded. In the case of a PSUS state, only the size of the PVOL is expanded, and the size of the SVOL is left as-is.

    摘要: A pool that is a storage area group composed of a plurality of real pages based on a plurality of RAID groups is managed. The storage system carries out the rebuild processing that includes the steps of copying each of data that has been stored into all allocated real pages among all real pages based on a specific RAID group to an unallocated real page based on at least one RAID group separate from the specific RAID group, allocating a real page of each copy destination to each virtual page of an allocated destination of an allocated real page of each copy source, and canceling an allocation of an allocated real page of each copy source to a virtual page.

    摘要: A second storage maps a migration source volume to a virtual volume of a migration destination volume according to storage virtualization technology. A host system including a host switches an access path from an access path to the migration source volume to an access path to the migration destination volume. The second storage executes copy processing of migrating, from the migration source volume to the migration destination volume, data in an assigned area of a virtual volume according to thin provisioning of the migration source volume based on the information contained in the first thin provisioning information in the first storage, and copying that data from the migration destination volume to a virtual volume according to thin provisioning of a copy destination volume in the second storage. The second storage associates the virtual volume of the copy destination volume with the migration destination volume in substitute for the original virtual volume.

    摘要: With a computer system having a host computer and first and second storage apparatuses, the second storage apparatus virtualizes first logical units in the first storage apparatus and provides them as second logical units to the host computer, collects configuration information about each first logical unit, and sets each piece of the collected configuration information to each corresponding second logical unit. The host computer adds a path to the second logical units and deletes a path to the first logical units. The second storage apparatus copies data stored in the first logical units to a storage area provided by the second storage device and associates the storage area with the second logical units.
