摘要： A magnetic disk array device is equipped with ATA magnetic disks, at least one disk array controller for controlling the ATA magnetic disks, and at least one processing offload function module provided between the disk array controller and the ATA magnetic disk. The disk array controller outputs one of a standard processing FC command for performing a standard processing such as a read or write processing, and an offload processing FC command for performing a vendor-unique offload processing. The processing offload function module performs a command mapping for the standard processing FC command and issues to the ATA magnetic disk a corresponding ATA command, and prepares a group of ATA commands for the offload processing FC command for optimum processing in an ATA protocol.

摘要： A storage system includes a plurality of disk apparatuses configuring a plurality of RAID groups, a spare disk apparatus, and a controller. The controller is adapted to copy data stored in a disk apparatus, whose error count exceeds a first threshold, to the spare disk apparatus. If an error count of a disk apparatus included in a RAID group exceeds a second threshold which is lower than the first threshold, the controller is adapted to check error counts of other disk apparatuses included in the same RAID group. If any of the error counts of the other disk apparatuses included in the same RAID group exceeds the second threshold, the controller is adapted to change the first value of the first disk apparatus and the other disk apparatuses included in the same RAID group.

摘要： The storage system includes a disk controller for receiving write commands from a computer, and a plurality of disk devices in which data is written in accordance with the control of the disk controller. The size of the first block which constitutes the data unit handled in the execution of the input/output processing of the data in accordance with the write command by the disk controller is different from the size of the second block which constitutes the data unit handled in the execution of the input/output processing of data by the plurality of disk devices. The disk controller issues an instruction for the writing of data to the disk devices using a third block unit of a size corresponding to a common multiple of the size of the first block and the size of the second block.
