Regarding a distributed storage system including a plurality of nodes, a first node among the plurality of nodes judges whether the same data as first data, which is written to a first virtual partial area managed by the first node from among a plurality of virtual partial areas, exists in the virtual partial area managed by another node among the plurality of nodes; when the same data as the first data exists in the other node, the first node executes inter-node deduplication for changing allocation of either one of logical partial areas for the first virtual partial area or the virtual partial area of the other node to which the same data is written, to the other logical partial area; and when I/O load on the first node after execution of the inter-node deduplication of the first virtual partial area and the predicted value is less than a first threshold, the first node executes the inter-node deduplication of a second virtual partial area managed by the first node from among the plurality of virtual partial areas obtained by dividing the virtual storage area.

Distributed storage system and control method for distributed storage system

A storage control apparatus performs, for each virtual area to which a physical area is allocated, any one of coarse-grained management for managing a correspondence relationship between a virtual area and a physical area in a first size unit, and fine-grained management for managing a correspondence relationship between a virtual area and a physical area in a second size unit smaller than the first size unit. The storage control apparatus manages mapping information that expresses a correspondence relationship between a virtual area and a physical area. The storage control apparatus performs at least one of change of any of fine-grained virtual areas to a coarse-grained virtual area and change of any of coarse-grained virtual areas to a fine-grained virtual area, based on the number of duplication areas of each virtual area and a size of the mapping information.

Proposed are a storage apparatus and its control method capable of restoring data of a virtual page to an appropriate device hierarchy according to its data value. This storage apparatus stores, in a backup-destination storage medium, data stored in the respective physical pages allocated with the virtual volume and management information of the virtual volume including information concerning the device hierarchy to which the respective physical pages belong according to a backup command of the virtual volume, and allocates a physical page of the same device hierarchy as the device hierarchy of the physical page that was allocated before the backup to each of the restoration-target virtual pages of the virtual volume, respectively, and writes corresponding data, which was read from the storage medium, into each of the allocated physical pages according to a restoration command of the virtual volume and based on the management information of the virtual volume stored in the storage medium.

Storage apparatus and its control method

Deduplication is executed in a storage device having low random access performance, such as an optical disk library. When an optical disk that is not inserted into an optical disk drive needs to be accessed in order to execute binary compare, data to be binary compared is stored in a temporary memory area in order to postpone the binary compare, and on the timing when the optical disk is inserted, the postponed binary compare is executed. Before second deduplication, which is deduplication between data to be stored in the storage device and the data in the optical disk library, is executed, first deduplication, which is deduplication between the data to be stored in the storage device and the data in the temporary memory area, is executed.

Information processing system

Availability of an information system including a storage apparatus and a host computer is improved. A host system includes a first storage apparatus provided with a first volume for storing data, and a second storage apparatus for storing the data sent from the first storage apparatus. In case of a failure occurring in the first storage apparatus, the host sends the data to be sent to the first storage apparatus to the second storage apparatus.

Information system and data transfer method

A secondary subsystem reads first differential data recorded in a magnetic tape device into a magnetic disk device, and manages such data based on second differential data that was created based on the read first differential data and differential management information. Then, whether differential data exists in partial data is determined based on the differential management information, and, if such differential data exists, the partial data is read into a cache memory, and differential data is applied to the partial data. Meanwhile, if differential data does not exist, the partial data is read into the buffer. Moreover, new full data is recorded by writing the partial data, which was read into the cache memory or the buffer, onto the magnetic tape device in parallel with other read processing.
