    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: 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 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: Various embodiments for optimized power savings in a storage virtualization system are provided. First meta data for physical resources which describes a power status of a storage resource in one of a powered-on/read-write, powered-on/read only, and powered-off power state is created. Second meta data for each of the physical storage resources which determines an actual performance of the physical storage resources and which supports optimization of a powering-on and a powering-off of the physical storage resources is created. A write request from one of a host and application to logical and virtual storage resource is executed.

    摘要: A method to select a deduplication protocol for a data storage library comprising a plurality of data storage devices configured as a RAID array, by establishing a normal deduplication protocol, a RAID failure deduplication protocol, and a multiple storage device failure deduplication protocol. The method receives host data comprising a plurality of interleaved data blocks. If the system is operating without any storage device failures, then the method processes the host data using the normal deduplication protocol. If the system is operating with a storage device failure, then the method processes the host data using the RAID failure deduplication protocol. If the system is operating with multiple storage device failures, then the method processes the host data using the multiple storage device failure deduplication protocol.
