Method for employing doubly striped mirroring of data and reassigning data streams scheduled to be supplied by failed disk to respective ones of remaining disks

摘要

The reliability of supplying data stored in a plurality of different memories to different users is enhanced by (a) dividing each of the memories into primary and secondary sections, (b) partitioning the data into successive blocks and (c) storing the blocks of data in sequence in respective ones of the primary sections. Then storing in sequence the blocks of data that have been stored in the primary section of one of the memories in respective ones of the secondary sections of the other ones of said disks.
