Disk arrays are commonly designed to ensure that stored data will always be able to withstand a disk failure, but meeting this goal comes at a significant cost in performance. We ...
—Disk scrubbing periodically scans the contents of a disk array to detect the presence of irrecoverable read errors and reconstitute the contents of the lost blocks using the bui...
Disk arrays (RAID) have been proposed as a possible approach to solving the emerging I/O bottleneck problem. The performance of a RAID system when all disks are operational and th...
Batch-correlated failures result from the manifestation of a common defect in most, if not all, disk drives belonging to the same production batch. They are much less frequent tha...
Redundant arrays of independent disks (RAID) provide an ecient stable storage system for parallel access and fault tolerance. The most common fault tolerant RAID architecture is R...
