Abstract
Enhancing management of controllers in a RAID system when a post-write-cache of a is disabled, by supplying a stripe buffer that stores sequential write requests—and before such requests are actually written in to the physical disc drives. The stripe buffer can temporarily store data, until the data level reaches the stripe buffer size. Thereafter, contents of the stripe buffer can be flushed onto disc.
