摘要： Since the whole storage device is blocked according to the conventional data saving method when failure occurs to the storage device in a storage subsystem, so that when failure occurs to two storage devices at the same time within a same RAID group, double failure is caused and data loss occurs. In order to solve the problem, the present invention divides a storage device into storage areas of predetermined units, constructs RAID groups from two or more storage areas, and when failure occurs to the storage area, selects a data migration destination storage area from either the RAID group in which failure has occurred or the RAID group other than the RAID group in which failure has occurred, migrates the data stored in the storage area where failure has occurred to the selected data migration destination storage area, and blocks only the storage area where failure has occurred.

摘要： A storage system coupled to a host has a nonvolatile semiconductor storage device that includes a nonvolatile semiconductor memory configured by a plurality of pages, and a storage controller coupled to the semiconductor storage device. In the case where data stored in the plurality of pages become unnecessary, with this plurality of pages being the basis of a region of a logical volume based on the nonvolatile semiconductor storage device, the storage controller transmits, to the nonvolatile semiconductor storage device, an unnecessary reduction request for reducing the number of pages that are the basis of the region having the unnecessary data stored therein. On the basis of the unnecessary reduction request, the nonvolatile semiconductor storage device invalidates the plurality of pages that are the basis of the region having the unnecessary data stored therein.

摘要： A first storage control apparatus unit has a first logical volume. A second storage control apparatus unit has a second logical volume, which is a virtual logical volume and is mapped to the first logical volume, and a third logical volume that is associated with the first logical volume. The second storage control apparatus unit receives, from a host, an I/O command which has information including, as information denoting an I/O-destination area, an ID of the second logical volume and an address of an area of the second logical volume. The second storage control apparatus unit identifies a logical volume having an area that serves as an entity of the I/O-destination area, and a storage control apparatus unit that has this logical volume.

摘要： A package controller of a flash package, upon receiving an update data write request with respect to a first logical storage area corresponding to a first LU that is treated as a backup target, manages a first physical storage area as a backup storage area in a state where pre-update data is maintained, newly allocates a second physical storage area to the first logical storage area, and writes the update data to the second physical storage area. The package controller, upon receiving an update data write request with respect to a second logical storage area corresponding to a second LU that is treated as a non-backup target, manages a third physical storage area allocated to the second logical storage area as an invalid storage area, and writes the update data to a fourth physical storage area newly allocated to the second logical storage area. The package controller performs control so as to use the first physical storage area to provide backup data for the first LU, and delete pre-update data stored in the third physical storage area.
