摘要： Times at which requests for a data read or data write from/to a logical volume are received are stored in memory as access times of a RAID group making up the logical volume. When a predetermined time has elapsed after the access time, a number of the hard disk drives according to the redundancy of the RAID group are set to a power saving mode. Assume there are first hard disk drives and second hard disk drives having shorter lifes and the RAID group exceeds a predetermined time after the access time. When the RAID group consists of only the first drives, a number of the first drives according to the redundancy of the RAID group are set to a power saving mode and when it consists of only the second drives, an arbitrary number of second drives are set to a power saving mode.

摘要： A disk array apparatus capable of reducing a disk drive fault rate where a time-out failure has occurred. The disk array apparatus includes a plurality of disk drives, and a control unit for performing data input/output processing of the disk drives in response to a data input/output request from a host system. The control unit includes: a memory for storing control information for specifying a failure of at least one of the disk drives, and failure information of the faulty disk drive, a circuit for specifying, from the failure information, the disk drive in which a time-out failure has occurred, and issuing an instruction to retry a control command to the disk drive, and a circuit for outputting a control signal to the faulty disk drive in order to hard reset the disk drive if the disk drive does not recover from the failure.

摘要： A disk array system having first and second housings and a controller for controlling the first and second housings. Fiber channel hard disk drives are received in the first housing, and serial ATA hard disk drives are received in the second housing. When reading data stored in a serial ATA hard disk drive in the second housing, the controller reads a plurality of pieces of data including the data to be read and parity data for the plurality of pieces of data from all the hard disk drives of an RAID group to which the hard disk drive storing the data to be read belongs. Thus, the controller examines whether the plurality of pieces of data including the data to be read are written in the hard disk drives with erroneous contents or not.

摘要： Proposed is a storage apparatus capable of alleviating the burden of maintenance work when a failure occurs in a part configuring the storage apparatus. This storage apparatus includes multiple disk drives and spare disk drives, and multiple controllers. When a failure occurs, this storage apparatus determines the operability status of the storage apparatus based on failure information. When operation can be continued, the storage apparatus continues to operate without performing any maintenance such as part replacement, and if operation cannot be continued, data is migrated to another storage apparatus.

摘要： The present invention aims to provide a high-reliability, low-cost disk array by emulating an ATA drive so that it can be used in the same way as an FC drive. To achieve this object, a disk array system of the present invention includes: a storage device having a logical unit logically set therein; the storage device includes: a plurality of disk devices having a first interface; and an interface converter converting between signals of the first interface adapted for the disk device and signals of a second interface adapted for the control device. The interface converter includes: a response time monitor portion for monitoring a time until a response is received from the disk device according to the data input/output request; and a notification issue portion for issuing to the control device a notification about an operative state of the disk device according to the monitored response time.
