Publication number: 20090228676Abstract: Proposed are a storage system and its management method having at least two storage apparatuses capable of partitioning an internal resource into logical partitions and managing the logical partitions, and which replicates data written into a primary volume of a primary storage apparatus as the replication source storage apparatus to a secondary volume of a secondary storage apparatus as the replication destination storage apparatus. With this storage system and its management method, configuration information of the logical partition, to which the primary volume belongs, is sent to the secondary storage apparatus, and the configuration of the logical partition to which the secondary volume belongs is set based on the configuration information of the logical partition to which the primary volume belongs.Type: ApplicationFiled: April 25, 2008Publication date: September 10, 2009Inventors: Yuki NAGANUMA, Hironori Emaru, Toshimichi Kishimoto, Nobuhiro Maki

Patent number: 7512888Abstract: A method for performing a system reconfiguration of a storage system includes displaying a configuration window visually showing a configuration of a plurality of components in the storage system within an operation screen. An input area is displayed within the operation screen, the input area being provided for entering one or more components to be reconfigured. A performance window is displayed within the operation screen, the preference window providing bandwidth utilization information of one or more of the components in the storage system. The configuration window, performance window, and the input area are all viewable at the same time without activating another operation screen.Type: GrantFiled: November 13, 2002Date of Patent: March 31, 2009Assignee: Hitachi, Ltd.Inventors: Shoji Sugino, Kozue Fujii, Toshimichi Kishimoto, Dai Taninaka

Patent number: 7426517Abstract: The time (response time) from the issue of a display request for the display of constructional information to the obtaining of predetermined desirable constructional information and the completion of display is long when a terminal device having (a graphical user interface) to manage and control the operation of a storage system by using a storage managing server is used. To reduce response time, the storage managing server receives a first request issued from a storage managing terminal for executing the processing of the storage managing server, and a second request for executing processing including the communication of constructional information of a storage device between the storage device and the storage managing server. The storage managing server starts processing with respect to the second request before the storage managing server transmits a response to the first request to the storage managing terminal.Type: GrantFiled: March 3, 2004Date of Patent: September 16, 2008Assignee: Hitachi, Ltd.Inventors: Toshimichi Kishimoto, Shuichi Yagi

Patent number: 7366838Abstract: In an exclusive lock management in common to both the In-Band and the Out-of-band, a lock control technique of a storage system capable of removing the factor that may cause the discrepancy in the configuration information in a disk array system is disclosed. In the storage system, a shared memory in a DKC of a storage subsystem has lock management information for uniformly managing the operation authority for the configuration information in the shared memory that is used in common by both the channels of the host terminals and the management client terminals, and a CPU in the DKC gives the operation authority for changing the configuration information to either the host machine or the management client based on the lock management information in the shared memory in response to an access request from the host terminals or the management client terminals.Type: GrantFiled: November 17, 2006Date of Patent: April 29, 2008Assignee: Hitachi, Ltd.Inventors: Dai Taninaka, Toshimichi Kishimoto

Patent number: 7150041Abstract: A storage system has an RMI interface for managing a storage. In starting an access, a WWW server distributes a storage manager program including an authentication function to a WWW browser of a manager. After a manager authentication by using a registered manager information file, an RMI management object dynamically creates an authentication key unique to the manager and an RMI interface having a limited function corresponding to the authentication key, and transmits the authentication key to a storage management program of the manager. An authenticated manager is allowed to imitatively use the RMI interface in accordance with the authentication key.Type: GrantFiled: December 18, 2001Date of Patent: December 12, 2006Assignee: Hitachi, Ltd.Inventors: Toshimichi Kishimoto, Yoshio Mitsuoka
