| Abstract: | In recent years,the performance of processors has continuously and rapidly been im-proving.On the other hand,the processing capability of a computer system has been increasing rapidly owing to the adoption of the multiprocessor.However,the performance of I/Ostorage systems has not been able to keep pace with such progress and many applications arenow limited by the speed of the storages rather than by the capability of the CPU. The bot-tleneck is going to be broken through by a storage system with an array of multiple disks ofa small diameter. This paper presents a new and reliable disk array of high reliability,theRedundant Array of Inexpensive Disks level seven(RAID7),in which the data storing unitwith the extended Hamming code is used. |
