摘要：
A data storage system includes a data storage array configured for de-duplication of duplicate data therein by: identification of a plurality of portions of data; a comparison of each portion of the data to identify duplicate data and identification of a link associated with each duplicate data; a determination of whether a Hamming link-separation-distance of the identified link is greater than twice a Hamming radius of an error correction code in the data storage system; and replacement of the duplicate data with the identified link when it is determined that the Hamming link-separation-distance is greater than twice the Hamming radius.
