    摘要: Proposed are a computer system and a data migration method which enable an improved response performance to a data access request from the user.A client computer or an application on a second file server transmits an access request for access to data stored in a first storage area to a second file server and, if an access request from the client computer is received, the second file server migrates data from a first storage area of a first storage apparatus to a second storage area of a second storage apparatus and, if an access request from the application on the second file server is received, data is migrated from the first storage area of the first storage apparatus to a third storage area of a third storage apparatus.

    摘要: The prior art information system could not migrate a file in a file sharing system provided by a file storage to a plurality of cloud storages having different forms of connection and different properties, and therefore, could not manage the files via a single Stub information. The present invention provides a data mover program in a file storage to select one or more migration destination cloud storages based on a migration policy, a connection information table of cloud storages and a property information table of cloud storages. Then, a Stub information of the migrated file is created, and an identification information of the file in the cloud storage is stored in a file information table. When access occurs from a client to a file storage, the data mover program downloads a file from the cloud storage stored in the file information table corresponding to the Stub information and provides the file to the client.

    摘要: Provided is a computer system containing plural storage systems which manages the bandwidth of the storage systems in accordance with storage area attributes. The computer system is characterized in that: a control unit incorporates related file information in metadata, the related file information containing information for identifying a second file which to be write-accessed in conjunction with access to a first file by a client computer, and an access type of the write access. The control unit refers to the related file information to obtain the second file and the access type when the first file is accessed by the client computer. The control unit reads, from the obtained second file stored in the disk device, data corresponding to the obtained access type, to store the read data in a cache memory.

    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: Recently, along with the increase in the importance of data protection, there are increasing demands for constructing a computer system capable of protecting data even when widespread disaster occurs. In order to reduce the risk of data loss even when widespread disaster occurs, the present invention computes the risk of data loss for each replication relationship of data (combination of storage subsystems storing the same data), and allocates data so that the risks of losing data of all replication relationships are optimized.
