摘要： Systems and methods are provided that confront the problem of failed storage integrated circuits (ICs) in a solid state drive (SSD) by using a fault-tolerant architecture along with one error correction code (ECC) mechanism for random/burst error corrections and an L-fold interleaving mechanism. The systems and methods described herein keep the SSD operational when one or more integrated circuits fail and allow the recovery of previously stored data from failed integrated circuits and allow random/burst errors to be corrected in other operational integrated circuits. These systems and methods replace the failed integrated circuits with fully functional/operational integrated circuits treated herein as spare integrated circuits. Furthermore, these systems and methods improve I/O performance in terms of maximum achievable read/write data rate.

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.
