摘要： A RAID-group converting apparatus converts two RAID groups into one RAID group. The RAID-group converting apparatus includes: a data-reading unit that reads at least non-parity data from data including the non-parity data and parity data, for each stripe from a plurality of recording media belonging to the two RAID groups; a parity-generating unit that generates two parities using the data belonging to a same stripe read by the data-reading unit; and a parity-writing unit that writes the two parities generated by the parity-generating unit into a parity storage area belonging to the same stripe.

摘要： Even if failure, or the like, occurs during the encryption process, the encryption process is surely resumed. A flag changing unit changes an encryption flag of one disk to being encrypted after an encryption request is received and before the encryption of the data stored on the one disk is started. The flag changing unit changes the encryption flag of the one disk to having been encrypted and changes the encryption flag of the other disk to being encrypted before copying the encrypted data from the one disk to the other disk is started. The flag changing unit changes the encryption flag of the other disk to having been encrypted after copying to the other disk is completed.

摘要： A plurality of music apparatus 10 to 30 such as an electronic musical instrument and a microphone apparatus are connected by wireless to a mixer apparatus 40. A Bluetooth module is adopted as wireless communication means to construct a piconet with mixer apparatus 40 functioning as a master and music apparatus 10 to 30 functioning as slaves. Audio signals and MIDI data from music apparatus 10 to 30 are transmitted by wireless to mixer apparatus 40 through isosynchronous communication procedure using Bluetooth modules 11, 21, 31, 41. In mixer apparatus 40, with regard to the MIDI data, music tone signals based on the MIDI data are produced, whereafter the produced music tone signals and the aforesaid audio signals transmitted by wireless are mixed. Wiring by means of cables between a plurality of music apparatus and a mixer apparatus is abolished, thereby eliminating the cumbersomeness of wiring and the restrictions accompanying the wiring.

摘要： In a disk array system, when a failure occurs in a disk unit under control, a disk controller performs a rebuild process for rebuilding data stored on the faulty disk unit on a spare disk unit (HS). When a rebuild control section accepts an I/O request from a host before completing the rebuild process in all target areas, the rebuild control section specifies a management unit area including a target area of the I/O request and determines whether the rebuild process is completed in the management unit area. If the rebuild process is not completed in the management unit area, the rebuild control section performs the rebuild process in the management unit area by a rebuild process section and rebuilds data on the HS. After that, an I/O request handling section handles the I/O request.

摘要： A RAID apparatus that at least duplicates identical data to store thus duplicated data, which, when an instruction of writing data is given, writes data to a local cache and to a mirror cache, and writes data of the local cache to a primary disk and writes data of the mirror cache to a secondary disk. When an instruction of reading out data is given, and specified data is retained in the caches, the RAID apparatus outputs valid data of the local cache or the mirror cache, while when specified data is not retained in the caches, the RAID apparatus outputs valid data of the primary disk or the secondary disk.

摘要： A storage system has a plurality of disk storage devices and a controller for controlling the plurality of disk storage devices, and diagnosis of a write miss to a disk of the disk storage device. The controller for controlling the plurality of disk storage devices attaches an ID to write data, and after write access to the disk drive, the controller reads the write data from the disk drive, and compares the ID of the read data and the attached ID. The controller updates the ID for each write command. Therefore the old write data and the new write data can be identified, accurate diagnosis is possible, and the failure of an individual disk drive can be detected immediately.
