摘要： Exemplary embodiments of the present invention comprise a method for the use of an intra-disk redundancy storage protection operation for the scrubbing of a disk. The method comprises initiating a disk scrubbing operation upon each disk of a plurality of disks that are comprised within a storage disk array, issuing a disk scrubbing command for a predetermined segment of the disks that are comprised within the storage disk array at a predetermined time interval, and identifying an unrecoverable segment on a disk. The method further comprises determining if unrecoverable sectors comprised within the unrecoverable segment can be reconstructed, and reconstructing the unrecoverable sectors of the unrecoverable segment and relocating the segment to a spare storage location on the disk in the event that the segment cannot be reconstructed within its original storage location.

摘要： A mechanism is provided for controlling a solid state storage device in which the solid state storage comprises erasable blocks each comprising a plurality of data write locations. Input data is stored in successive groups of data write locations, each group comprising write locations in a set of erasable blocks in each of a plurality of logical subdivisions of the solid state storage. The input data is error correction encoded such that each group contains an error correction code for the input data in that group. Metadata, indicating the location of input data in the solid state storage, is maintained in memory. An indication of validity of data stored in each data write location is also maintained. Prior to erasing a block, valid input data is recovered from the group containing write locations in that block. The recovered data is then re-stored as new input data.

摘要： For movement of partial data segments within a computing storage environment having lower and higher levels of cache by a processor, a whole data segment containing one of the partial data segments is promoted to both the lower and higher levels of cache. Requested data of the whole data segment is split and positioned at a Most Recently Used (MRU) portion of a demotion queue of the higher level of cache. Unrequested data of the whole data segment is split and positioned at a Least Recently Used (LRU) portion of the demotion queue of the higher level of cache. The unrequested data is pinned in place until a write of the whole data segment to the lower level of cache completes.
