    摘要: Availability of an information system including a storage apparatus and a computer is improved. First and second storage apparatuses execute remote copy of copying data written into a first primary volume from the computer to a second primary volume, at least one of the first and second storage apparatuses executes local copy of copying the data written into the first or second primary volume in a self-storage apparatus to the corresponding first or second secondary volume, and the computer switches the destination of a write request of the data from the first storage apparatus to the second storage apparatus in case of a failure occurring in the first storage apparatus.

    摘要: A storage group configured by a plurality of storage devices is configured by a plurality of storage sub-groups, and the respective storage sub-groups are configured from two or more storage devices. A sub-group storage area, which is the storage area of the respective storage sub-groups, is configured by a plurality of rows of sub-storage areas. A data set, which is configured by a plurality of data elements configuring a data unit, and a second redundancy code created on the basis of this data unit, is written to a row of sub-storage areas, a compressed redundancy code is created on the basis of two or more first redundancy codes respectively created based on two or more data units of two or more storage sub-groups, and this compressed redundancy code is written to a nonvolatile storage area that differs from the above-mentioned two or more storage sub-groups.
