摘要： A disk array controller 11 decides whether a command received from a host 20-22 is a write command or a read command. If it is a write command, the disk array controller 11 generates a data block, parity block and redundancy code block from the received data, and stores the data dispersed among the plurality of disk devices D00 -D0N. If it is a read command, the disk array controller 11 uses the parity block and redundancy code block to decide whether there is an error in the read data block, and in the event there is an error in the read data block, it is corrected using the parity block and redundancy code block.

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： Conventional methods for appending a validation code are not applicable to a disk array system in which the disk array comprises disk devices having a fixed sector length. The present invention solves this problem by separating validation codes from data blocks, bundling them together in blocks that can be easily matched with sectors, and carrying out all the associated management and control by hardware, such as coordination between validation codes and data blocks and operations of reading from and writing into the disk devices, thereby offering the same level of reliability as with conventional systems.
