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 pool, which is configured by multiple actual areas, is formed on the basis of two or more storage devices. A second storage control apparatus (DKC) determines, for each storage device, an unused capacity to be given to a first DKC with respect to each first DKC based on an unused capacity of each storage device and a request value of each storage device for each first DKC, and gives, for each first DKC, the unused capacity for each storage device determined with respect to the first DKC, to this first DKC. The request value of the storage device is based on a performance value, which is a value related to the performance of this storage device. The total capacity of multiple actual areas allocated to the virtual volumes by the first DKC is equal to or less than the unused capacity given with respect to each storage device.

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.
摘要翻译：由于当存储子系统中的存储装置发生故障时，根据传统的数据保存方法阻止整个存储装置，使得当在同一RAID组内同时发生两个存储装置的故障时，引起双重故障，数据丢失发生。为了解决该问题，本发明将存储装置划分为预定单元的存储区域，从两个以上的存储区域构成RAID组，当存储区域发生故障时，从两个以上的存储区域中选择数据迁移目的地存储区域发生故障的RAID组或发生故障的RAID组以外的RAID组将存储在发生故障的存储区域中的数据迁移到选定的数据迁移目的地存储区域，并且仅阻止存储区域发生故障
