摘要： A first storage control device is provided with a virtual LU for showing a logical volume possessed by a second storage control device as if it were its own volume. When data processing requested from a host device is, for example, a specific processing of large load (such as direct backup, logical volume copy, and so on), whether or not the requested processing can be executed by the second storage control device is judged. When it is executable, a command is transmitted to the second storage control device to make it take over the processing.

摘要： Tables (FIGS. 11 and 12) for stipulating information (WWN: WorldWide Name) for primarily identifying computers, information (GID: Group ID) for identifying a group of the computers and a logical unit number (LUN) permitting access from the host computer inside storage subsystem, in accordance with arbitrary operation method by a user, and for giving them to host computer. The invention uses management table inside the storage subsystem and gives logical unit inside storage subsystem to host computer group arbitrarily grouped by a user in accordance with the desired form of operation of the user, can decide access approval/rejection to the logical unit inside the storage subsystem in the group unit and at the same time, can provide the security function capable of setting interface of connection in the group unit under single port of storage subsystem without changing existing processing, limitation and other functions of computer.

摘要： When a bus is used as a data communication channel, data within a disk unit cannot be reproduced or copied into a spare disk while a control unit is making read/write processing based on a request from a host computer, or vice versa. Thus, a loop is constructed by a fiber channel capable of time division multiplex function, and the processing between the disk unit and the spare is performed not through the control unit so that the data within the disk can be copied into the spare while the processing between the host computer and the disk unit is being performed, or both processing operations can be executed in parallel.

摘要： According to the present invention, techniques for performing security functions in computer storage subsystems in order to prevent illegal access by the host computers according to logical unit (LU) identity are provided. In representative embodiments management tables can be used to disclose the Logical Unit in the storage subsystem to the host computers in accordance with the users operational needs. In a specific embodiment, accessibility to a storage subsystem resource can be decided when an Inquiry Command is received, providing systems and apparatus wherein there is no further need to repeatedly determine accessibility for subsequent accesses to the Logical Unit. Many such embodiments can maintain relatively high performance, while providing robust security for each LU.

摘要： A distributed information retrieval system in which the central computer is connected to a plurality of terminal devices and the management information includes a set of retrieval keys kept on the central computer side where the primary retrieval is achieved. The secondary retrieval thereafter is executed on the terminal side to reduce the load imposed on the central computer and to improve the response time for forwarding an answer to the user of the retrieval system.
