    摘要: In file de-duplication using hash value comparison, hash values of all target files must be calculated and actual data of all files must be read for hash value calculation, so that the processing time was long. The present invention provides a file storage system comprising a controller and a volume storing a plurality of files, the volume including a first directory storing a first file and a second file and a second directory storing a third file being created, wherein the controller migrates actual data of the second file to the third file, sets up a management information of the second file so that the third file is referred to when the second file is read, and if the sizes of actual data of the first file and the actual data of the third file are identical and the binaries of the actual data of the first file and the actual data of the third file are identical, sets up a management information of the first file to refer to the third file when reading the first file.

    摘要: Each time the file access request is received, it is discriminated whether there is an ACL which corresponds with the file system of the type following the switching in the file designated by the file access request. In cases where the judgment result is that there is no such ACL, an ACL which corresponds with the file system of the type following the switching is generated on the basis of an ACL which corresponds with the file system of the type prior to the switching which is associated with the designated file, and the ACL thus generated is used to control access in accordance with the received file access request.

    摘要: There has never been disclosed a method of executing migration on a fine-grained basis than a file system basis in a manner that is transparent to clients in a storage system with a plurality of servers to which a global name space is applied. In a storage system with a plurality of servers and a disk subsystem, which is coupled to the plurality of servers, a file system in the disk subsystem is assigned a first identifier, which is unique throughout the storage system, at least one of directories contained in the file system is assigned a second identifier, which is unique throughout the storage system, and a file contained in the file system is assigned a third identifier, which is unique throughout the file system. The server identifies a file below the directory that has the second identifier by the second identifier and by the third identifier.

    摘要: A control unit of a storage system controller receives an access command to a first file specifying a first access position in the first file. A storage apparatus stores management information of the first file and management information of each of subfiles obtained by dividing the first file. The management information of the first file contains information associating a data position in the first file and management information of a subfile containning data at the data position. The management information of each of the subfiles contains information associating a data position in the corresponding subfile and a physical storage position. The control unit references the management information of the first file to identify the management information of the subfile containning the data at the first access position, and references the management information of the identified subfile to identify a physical storage position of the first access position.

    摘要: To inhibit deterioration in the I/O performance of a file even if the file includes an area that is frequently accessed.An access account of the file is recorded, an area of the file is split into a plurality of partial areas at least one or more times if the access count exceeds a split threshold, the partial area (partial area including a hotspot with frequent access) in which the access count exceeded the split threshold is minimized, data corresponding to that partial area is ultimately uncompressed, and data corresponding to the other partial areas is compressed.

    摘要: An information processing system having a storage apparatus and a file sharing server. The storage apparatus comprises a plurality of storage devices for providing logical devices to store data; and a first processing unit for providing virtual logical units based on a mapping relation between the logical devices and the virtual logical units and being operative to switch the mapping relation dynamically according to an external request. The file sharing server comprises a cache memory including cache extents and a second processing unit controlled to provide the virtual logical units of the storage apparatus to a host system by using the cache extents, managing the mapping relation between the logical devices and the virtual logical units. The mapping between a logical unit and a logical device is dynamically switched as the logical devices store data provided from the host system according to external requests.
