    摘要: A RAID control apparatus and control method. The RAID control apparatus includes disk devices and disk control devices including a cache memory that stores cache data of a logical unit, and control unit, upon the logical units present in different disk devices being concatenated to each other, switching in-charge disk control devices such that a disk control device is in charge of access to the concatenated logical units without writing back the cache data stored in a cache memory of a source disk control device to the disk device.

    摘要: A storage apparatus includes a copy control unit for managing a copy session for copying an copy source data area in at least one of the first to the Mth copy source disk groups to an copy destination data area in a corresponding copy destination disk group, setting a first to an Mth copy session groups, each of the copy session groups including one or more copy sessions from the ith copy source disk group to the ith copy destination disk group as the copy session, and performing repeatedly a selection operation for cyclically selecting a copy session from each of the first to the Mth copy session groups in a predetermined sequence and a control operation for cyclically executing copy processing on a predetermined copy processing unit basis for the M copy sessions selected by the selection operation in a predetermined sequence for a prescribed number of times.

    摘要: A save control section included in a storage apparatus continuously performs writeback by which a data group is read out from a plurality of storage sections of the storage apparatus and by which the data group is saved in a data group storage section of the storage apparatus, or staging by which a data group saved in the data group storage section is distributed and stored in the plurality of storage sections according to storage areas of the data group storage section which store a plurality of data groups. An output section of the storage apparatus outputs in block a data group including the data stored in each of the plurality of storage sections. The data group storage section has the storage areas for storing a data group.
