    摘要: This embodiment (a system) addresses and reduces the RAID build time by only rebuilding the used blocks and omitting the unused blocks. This starts after a disk drive from a RAID system is failed and replaced and storage controller starts the process of rebuilding the data on the new disk drive. Storage controller determines the logical volumes that must be rebuilt, send a message requesting only used blocks for these logical volumes from the volume manager and then uses this information and only rebuild the used blocks for the failed disk system.

    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.

    摘要: A mirrored storage system for applications is provided, which enables and supports the variation and dynamic adaptation of the Recovery Point Objectives (RPO) based on policies. Furthermore, methods are provided for running such a mirrored storage system. Said mirrored storage system comprises a first storage system and at least one further storage system, wherein said first and said further storage system are connected via at least one mirror link. An application accesses said mirrored storage system via a network. Therewith, the data to be stored as response to a write command of said application can be mirrored according to a configurable time-varying RPO requirement of the application transmitting the corresponding write command.

    摘要: A method to sequentially deduplicate data, wherein the method receives a plurality of computer files, wherein each of the plurality of computer files comprises a label comprising a file name, a file type, a version number, and file size, and stores that plurality of computer files in a deduplication queue. The method then identifies a subset of the plurality of computer files, wherein each file of the subset comprises the same file name but a different version number, and wherein the subset comprises a maximum count of version numbers, and wherein the subset comprises a portion of the plurality of computer files. The method deduplicates the subset using a hash algorithm, and removes the subset from said deduplication queue.
