摘要： Techniques to assure genuineness of data stored on a storage device are provided. The storage device includes a storage controller that conducts I/O operations and management operations. A description of management operations and corresponding timestamps are recorded to an operation log stored in a memory. The memory additionally stores an attribute for each storage volume of the storage device. Write access to each of the storage volumes is dependent on the attribute.

摘要： A hierarchical storage system comprises a host computer and a storage system. The storage system comprises at lease two kinds of storage devices, a first tier storage and a second tier storage. The first tier storage is a high performance (or high cost) storage device, and the second tier storage is a lower performance (or lower cost) storage device. The storage system creates a virtual volume based on the first and second tier storages, and enables the host computer to access the virtual volume. A file system in the host computer knows which region of the virtual volume corresponds to the first tier storage and which region of the virtual volume corresponds to the second tier storage. When the file system receives a command to migrate a file from the first tier to the second tier storage, e.g., from a user, the file system examines the address information of the virtual volume where the file resides, and instructs the storage system to migrate the blocks of the designated addresses.

摘要： A method for migrating a block of data within a storage system includes migrating first data stored in a first storage volume of a first storage subsystem to a second storage volume in a second storage subsystem. The first data is a block of data that is presented to a host so that the first data may be accessed by the host. First setting information relating to the first data is copied from a first setting volume to a second setting volume. The first and second setting volumes are provided in the first and second storage subsystems, respectively. The second storage volume is presented to the host, so that the host may access the first data stored in the second storage volume via a communication network.

摘要： A computer system which has a plurality of computers and a storage device subsystem connected to the plurality of computers. The storage device subsystem has a plurality of storage devices and a plurality of interfaces, through which the subsystem is connected to the computers. One of the plurality of computers has a management means for holding therein data indicative of the storage devices and a connection relationship between the computers and storage device subsystem. Each computer, when wanting a new device, informs the management means of its capacity and type. The management means receives its notification and selects one of the storage devices which satisfies the request. And the management means instructs the storage device subsystem to set predetermined data in such a manner that the computer can access the selected device. The management means also returns predetermined data to the computer as a device assignment requester, the assignment requester computer modifies setting thereof to allow the computer in question can use the assigned device.

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.

摘要： In a storage area network (SAN), when a host accesses a storage system, the host is certified to restrict any unauthorized access. The storage system includes an access setting section and a certifying section to restrict accesses from respective hosts. When a host accesses data on a disk, the host issues an inquiry to a file server program of a host to receive information of a physical location of a file containing the data on the disk. The host accesses the disk according to the information. Simultaneously, the file server program allows, by a disk management program, the access to the area specified by the access request from the host.

摘要： A database update method for a computer system having a host computer and a storage sub-system where a database is maintained is disclosed. The storage sub-system includes first and second storage units containing duplicated data. The host computer accesses the first storage unit for data reading and the second storage unit for data writing. If incomplete processing to read is in process when an access request for data writing occurs, the host computer commands the stop of volume duplication of the first and second storage units and issues a write request. In response to this command, data is stored into only the second storage unit. Upon the completion of both read and write processing, the host computer commands the restart of volume duplication of the first and second control units to reflect the data stored into the second storage unit in the first storage unit.
