Abstract
Apparatus and circuitry are provided for supporting collection and/or verification of data integrity information. A circuitry in a storage controller is provided for creating and/or verifying a Data Integrity Block (“DIB”). The circuitry comprises a processor interface for coupling with the processor of the storage controller. The circuitry also comprises a memory interface for coupling with a cache memory of the storage controller. By reading a plurality of Data Integrity Fields (“DIFs”) from the cache memory through the memory interface based on information received from the processor, the DIB is created in that each DIF in the DIB corresponds to a respective data block.
