摘要： Disclosed is a system in which an index registration unit registers an index, which will be used for search processing, as a partitioned index which is partitioned on a time series basis, and a search means reads indexes older than a specified point in time, which is used as a search base point, to perform search processing, thereby searching for information based on a point in time in the past.

摘要： A system which includes at least one client, a plurality of file servers, each having a file system, and a switch logically arranged between the client and the plurality of file servers to provide file access services which virtually render the plurality of file systems accessible as a single file system, termed a ‘pseudo file system’, when viewed from the terminal. The switch distributes a command that starts generation of snapshots to the plurality of file servers, which file servers formulate respective snapshots responsive to the command that starts formation of the snapshots. The switch sets the plurality of snapshots, generated by the plurality of file servers, so as to be associated with the file system structure of the virtual file system at the time of formation of the snapshots.

摘要： Each of the sites interconnected to one another through a wide area network includes at least one client, a switch device logically disposed between the client and at least one server including a storage device, for providing to the client a file access virtually unifying of a plurality of storage devices, and an analysis device connected to the switch device. The switch device takes log information on the file access from the client. The analysis device determines data to be migrated to the server in a site to which the client belongs or the server in a site in vicinity of the site to which the client belongs, and commands the switch device to migrate the data. The switch device migrates the data based on the command from the analysis device.

摘要： Disclosed is a file access service system including at least one client, a plurality of file servers each having a function for limiting amount of use of a respective storage resource, and a switch apparatus inserted between the client and the plurality of file servers. The switch apparatus, based upon a set value of amount of use of a storage resource that has been set in the switch apparatus, sets a set value that limits amount of use of each storage resource in a respective one of the file servers. The switch apparatus surveys amount of use of each storage resource periodically in each of the file servers and, based upon the result of the survey controls the set value of the amount of use of each storage resource in each of the file servers.

摘要： Disclosed is a storage management system including at least one client, a first server having a primary storage, a second server having a secondary storage, and an intermediate device logically arranged between the client and the first and second servers. The primary storage includes a stub file in which there is recorded the position information of the real file migrated from the primary storage to the secondary storage. The intermediate device exercises control so that, when a file access request of the primary storage of a first server, issued by the client, is received by the intermediate device, the intermediate device receives the file access request and, if the file to be accessed is a stub file, and the access request necessitates accessing to the real file, the intermediate device accesses the real file of the secondary storage using the information of the stub file to return a response.

摘要： Disclosed is a data management apparatus comprising a message transfer/analysis unit that receives an object data access request from a client and returns a response; an object metadata storage unit that stores, as metadata, a set of ancillary information on data for an object and a data area corresponding to the ancillary information; an object metadata management unit that performs reading, updating, and registration processing for the metadata; a data conversion unit that sends the data access request to a data access unit, extracts object data; and a data access unit that sends a data access command, specified by the data conversion unit, to a file server or a database server and sends response data, received from the file server or the database server, to the data conversion unit.
