Patent number: 7107486Abstract: To provide a storage management device capable of performing restore at a high speed. In the storage management device that manages backup and restore of data stored in a storage device, a temporary restored image is created by applying each required delta image to the full backup image, a reverse delta image before the application of the applied delta image is created, and a number of delta application blocks concerning the applied delta image is recorded as cost information of applying delta. The delta backup restore unit determines a restore method by comparing a number of blocks, which is changed when restore is performed by applying each piece of the reverse delta image, with a number of blocks, which is changed when the restore is performed by applying each delta image, with reference to the cost information of applying delta.Type: GrantFiled: June 15, 2004Date of Patent: September 12, 2006Assignee: Hitachi, Ltd.Inventors: Wataru Okada, Hirokazu Ikeda, Masahide Sato

Publication number: 20060036825Abstract: Transfer of data and replication of data among several storage devices are executed without imposing a load on the computer connected to the storage system. For example, a first host computer monitors usage rates of transfer groups TG11, TG12 and physical path usage rate on a storage device interconnect physical path 50, and when either a usage rate or physical path usage rate goes above a predetermined value, issues to the first storage device 20 an instruction to allocate a reserved volume R11, R12. The first host adaptor 21 receiving the reserved volume R11, R12 allocation request allocates reserved volume R11 to transfer group TG1, whereby a virtual transfer volume is formed by transfer volume T11 and the reserved volume R11 allocated thereto. As a result, capacity of the virtual transfer volume is increased by the equivalent of the reserved volume R11 capacity, so that additional transfer frames may be stored.Type: ApplicationFiled: October 17, 2005Publication date: February 16, 2006Inventors: Nobuhiro Maki, Yuri Hiraiwa, Katsuhisa Miyata, Masahide Sato

Patent number: 6996828Abstract: A physical memory of a single computer is divided for each of a plurality of operating system (OS). A first OS is first loaded into the computer and runs. A multi-OS management program common to a plurality of OSs is incorporated into a virtual address space of the first OS as a device driver of the first OS. The multi-OS management program incorporated as the device driver is rearranged in a memory area shared by OSs so that the multi-OS management program has the same virtual address in any OS. In this state, the second OS program itself is loaded in the virtual address space of the second OS by execution of the multi-OS management program in the first OS. Execution of the multi-OS management program is switched from the multi-of management program in the first OS to the multi-OS management program in the second OS. Then, the second OS is started by execution of the multi-OS management program in the second OS to thereby run the plurality of OSs on the single computer.Type: GrantFiled: August 29, 2000Date of Patent: February 7, 2006Assignee: Hitachi, Ltd.Inventors: Shinji Kimura, Toshiaki Arai, Masahide Sato, Toshikazu Umezu
