    摘要: A storage unit includes a cache memory, a cache controller which accesses the cache memory, one or more disk units, a data receiving unit, a merge interpolation determination unit, a data readout unit, a write data generation unit and a data write unit. The data receiving unit receives, from the cache controller, unit readout data that includes update records updated by the cache controller and is unit of data read from the cache memory. The merge interpolation determination unit determines whether the received unit readout data is merge interpolated. The data readout unit reads, from the disk unit, data corresponding to the unit readout data when the unit readout data is determined to be merge interpolated. The write data generation unit generates data to be written to the disk unit by merge interpolating the unit readout data. The data write unit writes, to the disk unit, the generated data.

    摘要: A storage apparatus has a plurality of storage media including each storage area in which a stripe is set extending over the storage area of the plurality of storage media. An access unit that writes a format data into the storage area, wherein when the plurality of storage media are formatted, the access unit writes an unformatted-state identifier indicating incompletion of formatting into at least a portion of storage area to be included in the stripe, or when the storage area to be included in the stripe is accessed for writing new data, the access unit reads out existing data stored in the storage area included in the stripe to be accessed. And when the unformatted-state identifier is detected from the existing data that has been read out, the access unit writes the new data or the format data to be written by formatting into the storage area.

    摘要: A storage apparatus includes a plurality of first storage mediums in which data is redundantly stored and a controller. The controller includes a formatting section which performs formatting in each of the plurality of first storage mediums, a detection section which detects a failure that has occurred in the plurality of first storage mediums, a control section which makes the formatting section stop the formatting at the time of the detection of the failure by the detection section and which rebuilds the data stored in the plurality of first storage mediums in which the failure has occurred in a second storage medium other than the plurality of first storage mediums, and a rebuild processing section which rebuilds the data stored in the plurality of first storage mediums in the second storage medium in accordance with instructions from the control section.
