摘要: Several new disk arrays have recently been proposed in which the parity groupings are uniformly distributed throughout array so that extra workload created by a failure can be evenly shared all surviving disks, resulting best possible degraded mode performance. Many now also put multiple spare disks expensive service calls deferred. Furthermore, sparing scheme called sparing, spaces actually array. This means after rebuild will logically different from original The authors present an algorithm for constructing and maintaining with repeated uniform group distribution is achieved each successive failure. >
