Publication number: 20070150680Abstract: A storage device system includes an information processing device and at least first and second storage devices. The first and second storage devices are equipped with first and second storage volumes, respectively. The information processing device generates first data including a first instruction that is to be executed by the second storage device, and sends a write request to a first write request section to write the first data according to a first communications protocol in the first storage volume. When the first data written in the first storage volume is the command to be executed by the second storage device, the first storage device sends to a second write request section a write request to write the first data according to a second communications protocol in the second storage volume. The second storage device executes the first command set in the first data that is written in the second storage volume.Type: ApplicationFiled: February 16, 2007Publication date: June 28, 2007Inventors: Naohisa Kasako, Shuji Kondo, Toru Suzuki, Takeshi Koide

Patent number: 7216209Abstract: It is an object of the present invention to conduct data transfer or data copying between a plurality of storage systems, without affecting the host computer of the storage systems. Two or more auxiliary storage systems 100B, 100C are connected to a primary storage system 100A connected to a host device 180. The auxiliary storage systems 100B, 100C read journals of data update from the primary storage system 100A at respective independent timings, save the journals in prescribed logical volumes JNL 2, JNL 3, produce copying of the data present in the primary storage system 100A based on the journals present in the logical volumes JNL 2, JNL 3 at the independent timings, and save the copies in auxiliary logical volumes COPY 1, COPY 3. The primary storage system 100A holds the journals till both auxiliary storage systems 100B, 100C read the journals and restore. The timing of journal read can be controlled according to the journal quantity, processing load, and the like.Type: GrantFiled: January 28, 2004Date of Patent: May 8, 2007Assignee: Hitachi, Ltd.Inventor: Naohisa Kasako

Patent number: 6892203Abstract: A technique is described to enable exclusive control on a file basis in a storage system while remote double recording is performed between storage controllers. A first shared-file controller has a table that stores control information used for excluding read and write to that file on a file basis. When the shared-file controller receives a data write request, it sets access to the file as exclusive, and then issues a command to a second shared file controller to set control information for that file. After data is written into a storage medium and mirrored to a second storage medium, a copy of the file management information is stored in memories of the shared-file controllers. The consistency of the file management information is maintained between the two file controllers by copying the file management information over the network.Type: GrantFiled: August 16, 2002Date of Patent: May 10, 2005Assignee: Hitachi, Ltd.Inventors: Naohisa Kasako, Shigeru Kishiro, Takahiko Takeda
