摘要： The present invention enables to secure data reliability by avoiding data loss in an early failure period of an operation of a disk array system to which no particular measures have been taken conventionally. A controller of the disk array system stores first data to be stored in a HDD into a part of the region of one or more HDDs of an overall storage region composed of a plurality of HDDs and stores backup data of the stored first data into a part of the region of one or more HDDs in such a manner that they may be stored in the different HDDs. When there are no enough free space regions to store the first data in the overall storage region, the region in which the backup data is stored is overwritten to be used.

摘要： A disk array system is provided, which can improve data reliability by verifying addressing correctness of data access by applying a redundant code to user data even if using an HDD compatible with serial ATA, etc. whose sector length cannot be extended. When writing the object data to an HDD, a controller stores partly-extracted data of the object data in a control area and performs an XOR operation between the partly-extracted data and a check code generated by calculations. Then, the operation-resultant data (CC-embedded data) are returned to the object data and written in the HDD. Also, when reading the object data from the HDD, the controller fetches the CC-embedded data, performs an. XOR operation between the fetched data and the check code, and compares and collates the operation-resultant data with the partly-extracted data in the control area to check the addressing correctness and restore the user data.

摘要： A storage apparatus and its control method capable of implementing thin provisioning and reducing power consumption of storage devices are provided. The storage apparatus classifies a plurality of storage devices, which provide a pool with a storage resource, into a plurality of groups; performs thin provisioning operation by setting some of the plurality of groups to an active mode, in which the storage devices belonging to the groups are made to enter an activated state; sets other groups to a power-saving mode in which the storage devices are made to enter a power-saving state; and sequentially switches between the group(s) in the active mode and the group(s) in the power-saving mode among the plurality of groups.
