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： In a storage system for performing data backup using a battery during blackout, when the blackout continues for a long time, problems such as the loss of volatile memory data due to the consumption of battery capacity and the difference in recovery time between controller units after power recovery occur during restarting of the system. The present invention solves the problems by selecting (a1) battery backup or (a2) saving of data in a nonvolatile device based on the battery capacity or setting of modes, and selecting (b1) inhibiting restart of the system or (b2) storing of data in the volatile memory to a nonvolatile memory means and performing access via write-through based on the remaining capacity of the battery when restarting the system after power recovery. Further, the system enables to increase and decrease the volatile memory capacity of the write area and mutually confirms synchronization of controller units and contents of volatile memories. Thereby, the system enables to prevent data loss and inconsistency of data.

摘要： This storage system supplies, to a plurality of computers, a plurality of duplicate volumes (CVOLs) (corresponding to duplicates of a master volume (MVOL) upon which is stored an electronic object (EO) that is common to the plurality of computers). Both the MVOL and the CVOLS are virtual logical volumes that follow sync provisioning. In the plurality of CVOLs, a plurality of physical regions that are allocated to the MVOL (i.e. regions in which the electronic object is stored) (PAs) are allocated. A storage, when writing an electronic module (EM) to which the EO is applied to the first CVOL, copies data within a first PA that is allocated to the virtual region (VA) that is the write destination to a second PA, writes the EM to the second PA, and moreover allocates the second PA to a VA of the write destination, instead of the first PA. And the storage allocates the second PA to a VA within the second CVOL corresponding to the VA of the write destination, instead of the PA that is allocated to that VA.

摘要： A storage control apparatus of the present invention reduces the frequency of disk drive failures. An error management part manages the number of times errors occur in respective disk drives. A disk drive in which the number of errors meets or exceeds a threshold value is selected as a disk drive to be restarted. A restart control part commences difference management prior to restarting the disk drive targeted for restart. A difference management part manages parity group-related update locations using a difference bitmap. After commencing difference management, the restart control part restarts the disk drive in which the error was detected. This makes it possible to resolve an error caused by a firmware hangup or the like.
