Patent number: 8296468Abstract: A storage controller that performs user-friendly information display, simplifies updating of support information, has external storage controllers to provide sufficient input/output performance, and expands the range of external storage controllers to be supported; and a controlling method for that storage controller. The storage controller includes a code extract/convert unit for converting a first code indicating a vendor name and/or device name of an external storage controller, obtained based on inquiry data transmitted from the external storage controller, into a second code indicating a real vendor name and/or real device name of the external storage controller. The storage controller creates support information that compiles information of each model regarding whether or not it can be connected to the respective external storage controllers. Furthermore, a path control system and a timeout time can be set for the respective external storage controllers.Type: GrantFiled: September 29, 2011Date of Patent: October 23, 2012Assignee: Hitachi, Ltd.Inventors: Kosaku Kambayashi, Dai Taninaka

Patent number: 6993636Abstract: Disk units operable under control of different disk control units hold the same data. Under circumstances in which data is duplexed, when data is duplexed again after data that is generally saved as backup data was accessed for reading and writing, in order to efficiently duplex data, update places of both original data and sub-data updated during the duplexing of data is interrupted are registered on an access information management table of an original disk control unit. When the original disk control unit receives a duplexing resume command, the duplexing of data may be efficiently reorganized by copying original data corresponding to an access place produced during the duplexing is interrupted from information of the access information management table to the backup data or by copying the backup data to the original data.Type: GrantFiled: September 30, 2003Date of Patent: January 31, 2006Assignee: Hitachi, Ltd.Inventors: Hitoshi Shiozawa, Koji Ozawa, Takahisa Kimura, Kazuhito Suishu, Kosaku Kambayashi, Katsunori Nakamura
