摘要： A method of de-duplicating duplicate data in a data storage system that includes identifying a plurality of portions of data, comparing each portion of the data to identify duplicate data and identifying a link associated with each duplicate data, determining whether a Hamming link-separation-distance between the identified link and all other existing links is greater than twice the Hamming radius of an error correction code in the data storage system, and then replacing the duplicate data with the identified link.

摘要： Data for deduplication is received. The received data is deduplicated if selected conditions corresponding to the deduplication are satisfied, wherein the selected conditions include a deduplication ratio, a data deduplication threshold, and a data quiescence measure. Deduplication of the received data is discontinued if the selected conditions corresponding to the deduplication are not satisfied.

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 efficient track destage in secondary storage in a more effective manner, for temporal bits employed with sequential bits for controlling the timing for destaging the track in a primary storage, the temporal bits and sequential bits are transferred from the primary storage to the secondary storage. The temporal bits are allowed to age on the secondary storage.

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.
