Patent number: 7430648Abstract: 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: GrantFiled: February 16, 2007Date of Patent: September 30, 2008Assignee: Hitachi, Ltd.Inventors: Naohisa Kasako, Shuji Kondo, Toru Suzuki, Takeshi Koide

Patent number: 7213114Abstract: Two data centers located in the vicinity are connected using a synchronous transfer copy function, and one of the data centers is coupled with a third data center disposed at a remote location by an asynchronous remote copying function. The order whereat a storage sub-system located in the vicinity has received data from a host is consistently guaranteed, and the third data center holds the data. Further, each storage sub-system includes a function whereby, during normal operation, data can be exchanged and the data update state can be obtained by the storage sub-systems located in the two data centers that do not directly engage in data transmission.Type: GrantFiled: August 12, 2004Date of Patent: May 1, 2007Assignee: Hitachi, Ltd.Inventors: Toshio Nakano, Katsunori Nakamura, Mikito Ogata, Yoshinori Okami, Seiichi Higaki, Hiroshi Abei, Shigeru Kishiro, Teruo Nagasawa, Takeshi Koide

Patent number: 6845435Abstract: According to the present invention, techniques for performing real time backup of data in the presence of a pending hazard, such as a natural disaster, or the like. Embodiments can provide data storage controllers, networked data storage systems, methods and the like, that detect imminent hazardous conditions and alter backup behavior to provide greater integrity of backed up data. In a representative embodiment according to the present invention, update of the primary data is temporarily suspended after the recognition of a probable occurrence of a hazardous event. By suspending updating the primary data temporarily, the increase of un-updated secondary data can be prevented, so that lost data is decreased. Then, the un-updated secondary data can be updated quickly or exclusively, in order to avoid un-updated secondary data.Type: GrantFiled: January 14, 2004Date of Patent: January 18, 2005Assignees: Hitachi, Ltd., Hitachi Information Technology Co., Ltd.Inventors: Teruo Nagasawa, Takahisa Kimura, Takeshi Koide

Patent number: RE43600Abstract: In a data processing system in which main and sub disk storage devices are under the control of individual each disk control devices, the write processing time is reduced by selectively sending data according to the command-chaining time between main and sub disk control devices. A section for judging cable length and function of the sub disk control device 36 estimates command-chaining time between a pair of main and sub disk storage devices. The channel command analyzing section 31 estimates the number of records to be transferred and the length of a record using a LOCATE RECORD command. The command judgment section for the sub disk control device 32 optimizes the command-chain to be issued to the sub disk control device using the above-mentioned information. Then, the section for issuing command to the sub disk control device 35 issues the optimized command chain. Thus, a shorter transmission time is realized by either sending individual records or an entire track of data.Type: GrantFiled: July 9, 2003Date of Patent: August 21, 2012Assignee: Hitachi, Ltd.Inventors: Koji Ozawa, Kazuhide Sano, Takeshi Koide, Katsunori Nakamura
