摘要： Times at which requests for a data read or data write from/to a logical volume are received are stored in memory as access times of a RAID group making up the logical volume. When a predetermined time has elapsed after the access time, a number of the hard disk drives according to the redundancy of the RAID group are set to a power saving mode. Assume there are first hard disk drives and second hard disk drives having shorter lifes and the RAID group exceeds a predetermined time after the access time. When the RAID group consists of only the first drives, a number of the first drives according to the redundancy of the RAID group are set to a power saving mode and when it consists of only the second drives, an arbitrary number of second drives are set to a power saving mode.

摘要： Spare disk drives are provided to a chassis for storing storage devices, and, when any one of the storage devices configuring RAID fails, the storage controller copies data of the failed storage device to a spare storage device, and recognizes an additional storage device inserted into the spare disk drive as the spare storage device. Thereafter, when the foregoing storage device fails, the storage controller reproduces data of the failed storage device, copies this data to an additional storage device inserted into the spare disk drive, and recognizes the additional storage device inserted into the spare disk drive as a spare storage device. Subsequently, when the foregoing storage device fails, the storage controller reproduces data of the failed storage device and copies this data to an additional storage device inserted into the spare disk drive. RAID 6 is maintained thereby.

摘要： To enable reduction of the data capacity while inhibiting degradation of read performance.If any of a plurality of host systems issues a request to write duplicate data as objective data which is identical to already stored data, a processor for a disk controller controls a data transfer control unit so that part of the duplicate data will be kept in accordance with a specific rule instead of entirely eliminating writing of the duplicate data.

摘要： A storage controller of the present invention reduces maintenance work by the user by irreplaceably mounting the respective component parts inside an enclosure. A plurality of disk drives, which comprise a spare drive, and repair slots are arranged in close proximity in a matrix on the front side inside the enclosure. A backboard is disposed rearward of the respective disk drives. A plurality of control boards are arranged rearward of the backboard by being stacked one atop the other. A plurality of disk drives and a plurality of batteries respectively stacked one atop the other are arranged on the one side of the respective control boards. A plurality of power devices stacked one atop the other are arranged on the other side of the respective control boards. A plurality of cooling fans are arranged in the center part of the enclosure. The respective parts are affixed to the enclosure so as to be irreplaceable under normal circumstances.
