    摘要: A control apparatus, coupled to a storage medium via communication links, controls data write operations to the storage medium. A cache memory is configured to store a temporary copy of first data written in the storage medium. A processor receives second data with which the first data in the storage medium is to be updated, and determines whether the received second data coincides with the first data, based on comparison data read out of the storage medium, when no copy of the first data is found in the cache memory. When the second data is determined to coincide with the first data, the processor determines not to write the second data into the storage medium.

    摘要: According to an embodiment, a storage apparatus including: a plurality of storage media of which a first RAID is composed, a logical storage area of the first RAID for storing data being set over; a plurality of expansion storage media of which a second RAID is composed; a spare storage medium that is different from in any of the storage media or the expansion storage media; and a configuration control unit that when the spare storage medium is set in the first RAID, sets the logical storage area in the storage media, and when the expansion storage media are set in the storage apparatus, sets the expansion storage media in the second RAID, excludes the spare storage medium that is set in the first RAID, and moves the logical storage area that is set in the first RAID to the second RAID.
