Deterministic data verification in storage controller

A system for performing deterministic data verification in a computing storage environment, comprising:

• a memory;
• and
• a storage controller including a processing device coupled to the memory and operational in the computing storage environment, wherein the storage controller is adapted for configuring each of a plurality of concurrent write tasks to be placed in a plurality of overlapping data storage ranges by:
• 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, the generating including generating a plurality of nodes, wherein each node represents a range from a starting address offset to an ending address offset;
• and
• analyzing each of a plurality of read tasks 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.

A computer program product for performing deterministic data verification by a storage controller operational in a computing storage environment, the computer program product comprising a non-transitory computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:

• a first executable portion for configuring each of a plurality of concurrent write tasks to be placed in a plurality of overlapping data storage ranges by:
• 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, the generating including generating a plurality of nodes, wherein each node represents a range from a starting address offset to an ending address offset;
• and
• a second executable portion for analyzing each of a plurality of read tasks 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.
