摘要： A flash memory controller is configured to hold a read pattern defining an order of selection of read options specifying a parameter value for a read from the flash memory chip. The flash memory controller is configured to execute error correction on data read from the flash memory chip in accordance with the read command. The flash memory controller is configured to designate a next read option specified in the read pattern to read the data from the flash memory chip in a case where all errors in the read data are not corrected by the error correction.

摘要： The first storage apparatus provides a primary logical volume, and the second storage apparatus has a secondary logical volume. When the first storage apparatus receives a write command to the primary logical volume, a package processor in a flash package allocates first physical area in the flash memory chip to first cache logical area for write data and stores the write data to the allocated first physical area. And when the package processor receives journal data creation command form the processor, allocates the first physical area to second journal area for journal data without storing journal data corresponding to the write data.

摘要： A first storage system comprises a first RAID group comprising multiple first storage devices, which constitute the basis of a first logical volume. A second storage system comprises a second RAID group comprising multiple second storage devices, which constitute the basis of a second logical volume. The RAID configuration of the first RAID group and the RAID configuration of the second RAID group are the same, and the type of a compression/decompression function of the respective first storage devices and the type of a compression/decompression function of the respective second storage devices are the same. Compressed data is read from a first storage device without being decompressed with respect to the data inside a first logical volume, and the read compressed data is written to a second storage device, which is in the same location in RAID in the second RAID group as the location in RAID of this first storage device.

摘要： A cache control apparatus comprises a primary cache part, a secondary cache part for caching data destaged from the primary cache part, and a controller connected to the primary cache part and to the secondary cache part. The secondary cache part has a first storage part and a second storage part having a lifetime longer than that of the first storage part. The controller determines whether the data destaged from the primary cache part is to be stored in the first storage part or the second storage part in the secondary cache part, based on a use state indicating whether or not the data has been updated, and stores the data in the first storage part or the second storage part determined.
