  • Deterministic data verification in storage controller
    Patent number: 8819502
    Abstract: Exemplary method, system, and computer program embodiments for performing deterministic data verification by a storage controller are provided. Each of a plurality of concurrent write tasks is configured to be placed in a plurality of overlapping data storage ranges by performing at least one of: implementing a data generation function for generating pseudo-random data using a data seed, and generating a range map, the range map utilized as a lookup data structure to verify a chronological order for performing the plurality of concurrent write tasks, wherein a data address space is first designated in the range map as undetermined. Each of a plurality of read tasks is analyzed by comparing data read from a sub range in the plurality of overlapping data storage ranges against the data seed associated with the sub range.
