    摘要: An input/output scheduling unit forms input/output groups obtained by grouping inputs/outputs to/from a disk apparatus. The input/output scheduling unit defines a ratio of the time during which each input/output group uses the disk apparatus and defines quanta &tgr;1 to &tgr;3 during which each input/output group can continuously use the disk apparatus on the basis of the defined time ratios. When input/output requests are received from a plurality of input/output groups to the disk apparatus, the input/output scheduling unit performs the time-sharing for sequentially switching the allocating times &tgr;1 to &tgr;3 between the input/output groups which competed and using the disk apparatus. Further, an allocating time of the remaining quanta is distributed to the quanta on the shortage side by an allocating time control unit in accordance with a degree of jam of each input/output group.

    摘要: A disk array control apparatus controls a disk array having a redundant configuration with two or more disk devices and a spare disk provided for lack of redundancy in the disk array. And the disk array control apparatus includes a failure detecting unit for detecting the lack of redundancy in the disk array, and a rebuilding control unit for performing rebuilding processing on a dedicated spare disk device assigned to the disk array with the lack of redundancy, the dedicated spare disk being the spare disk dedicatedly assigned to the two or more disk arrays including the disk devices having a same characteristic as that of the spare disk.

    摘要: A response of a disk device during rebuild can be sped up. A disk array control device determines whether or not there is a normal read request during rebuild. If there is a read request during rebuild, data is read by sequentially switching a plurality of disk devices in a certain block size unit lower than a block size in which each disk device reads data during normal read.

    摘要: A device adaptor that controls a disk, wherein a storage area is divided into a plurality of blocks, detects a block that includes a read error. Next, the device adaptor detects a write omission in blocks that are within a predetermined range from the block that includes the read error. To be specific, the device adaptor reads data from the blocks that are in the vicinity of the block that includes the unrecovered read error in a suspect disk. Next, the device adaptor reads from a redundant disk, data of a block that corresponds to the block that includes the unrecovered read error (data of block “B” in an example shown in FIG. 1) and compares the read data to the data read from the suspect disk to detect the write omission.

    摘要: An indoor unit of an air conditioner includes a cross flow fan and an indoor heat exchanger. The cross flow fan generates a flow of air. The heat exchanger has a two row part and a one row part. The one row part has an area that is smaller than the two row part, and is disposed so that it overlaps one part of the two row part in an air transit direction. Furthermore, during a cooling operation, a refrigerant flows to the two row part before flowing to the one row part.
