Patent number: 6912614Abstract: A controller refers to an address translation table and searches for the logical address of a valid logical block used by a host computer. Then, the controller reads from a disk array only a physical stripe that includes the physical block of a physical address corresponding to the valid logical address. Based on the read physical stripe, the controller restores data of a failing disk drive and writes the restored data in a spare disk drive that is used in place of the failing disk drive.Type: GrantFiled: August 30, 2002Date of Patent: June 28, 2005Assignee: Kabushiki Kaisha ToshibaInventor: Haruo Tomita

Patent number: 6901479Abstract: A controller retrieves effective logical addresses sequentially according to a copy of an address translation table at the time of the start of storage capacity expansion in the process of expanding the storage capacity of a disk array by adding a disk drive to the disk array. The controller stores the data in the logical address into a restructured write buffer each time an effective logical address is retrieved. The controller writes one stripe worth of data blocks including one stripe of logical blocks and a logical address tag block into an empty area different from the area in which the data to be updated has been stored in the data array each time one stripe worth of logical blocks of data is accumulated in the write buffer.Type: GrantFiled: January 29, 2003Date of Patent: May 31, 2005Assignee: Kabushiki Kaisha ToshibaInventor: Haruo Tomita

Patent number: 6886068Abstract: In writing all logical blocks in a data stripe in a disk array, a controller generates a logical address tag block corresponding to these logical blocks. The controller stores the logical address tag block in logical address tag block areas ensured other than data areas on the disk array which store the data stripe.Type: GrantFiled: August 30, 2002Date of Patent: April 26, 2005Assignee: Kabushiki Kaisha ToshibaInventor: Haruo Tomita

Patent number: 6233648Abstract: A disk storage system with a RAID architecture includes a write buffer having a storage capacity corresponding to one stripe, a buffer management table, and a controller.
