摘要： An object of the present invention is to dynamically transfer a virtual file server within a cluster that is configured by a plurality of file servers in which virtual file servers are set up. A storage system includes: a first file server; a second file server; and a disk subsystem, in which: the first file server and the second file server each include a virtual file server control unit that sets up the virtual file server; the virtual file server includes a routing table that stores path information necessary for communication; and the virtual file server started up in the second file server determines a communication path by using the routing table used by the virtual file server in the first file server after taking a failover from the virtual file server of the first file server to the second file server.

摘要： Provided is a storage system as follows. A server holds a management table that serves to manage a mount point of a file system. The management table stores a file system identifier that uniquely identifies the file system within the storage system, mount point information that indicates the mount point of the file system, and a management server identifier that indicates an identifier of the server that manages the file system. The contents stored in the management table of each server are the same. Upon reception of a request to obtain a file handle, each server returns the file handle requested to be obtained. The file handle indicates, uniquely within the storage system, the storage area on the disk subsystem in which the file relating to the request is stored.

摘要： The present invention relates to a migration of a file from a path denotative NAS server to an ID denotative NAS server. In a file management device according to one embodiment, a migration-use path denotative NAS access section obtains a file deposit location from the path denotative NAS server, selects a migration target file based on the deposit location, and sends a read request with the deposit location of the migration target file to the path denotative NAS server, so as to obtain the migration target file. A migration-use denotative NAS access section 44 generates a write request with the migration target file, sends it to the ID denotative NAS servers, and writes the file therein. In addition, the migration-use ID denotative NAS access section registers a GUID received from the ID denotative NAS servers in a file name/GUID management table, together with the file name of the migration target file.

摘要： A system for controlling spinning of a disk is provided to prevent deterioration of the access response speed and to suppress the power consumption. The system includes a controller controlling a file system, and a disk array system storing data of the file system. The disk array system includes a plurality of logical volumes, each of which is configured by at least one disk device, and a disk controller controlling data input/output to/from the plurality of logical volumes. The plurality of logical volumes includes at least one first type logical volume which is controlled so that spinning of a disk device that configures the logical volume can be stopped, and at least one second type logical volume which is controlled so that spinning of a disk device that configures the logical volume cannot be stopped. Data satisfying a predetermined condition is stored in the second type logical volume.

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 storage system conducting remote copy functions such that, when data is updated at a local site, contents of the update can be referred to in real time by storage at a remote site. A disk-control unit at a remote site receives file data written in accordance with an update of a file in a storage system at a local site and a history of the file-management information from the storage system at the local site and stores the data and the history. A file-system processing unit refers to the history and updates the file-management information in a file-system cache in accordance with the update of the file in the storage system at the local site. When a client issues a read request, the file-system processing unit refers to the file-management information updated in the file-system cache and transfers the contents of the update of the file to the client.

摘要： A system for performing efficient backup in an environment where a plurality of file servers exist, making the plurality of file servers externally look like a single apparatus. The present invention provides a computer system comprising hosts, first and second file servers connected to the hosts, and a storage system connected to the first and second file servers. The second file server determines that a file as a backup object is managed by the first file server, and notifies the first file server of an instruction of backup. In response to this instruction, the first server sends the second file server an identifier of a storage device that stores duplicate data of the file in question. Based on the received identifier, the second file server sets a path to that storage device, and obtains the backup data from that storage device.
