Abstract:
1. A method, comprising: discovering by redundant array of independent disks (RAID) controller circuitry domain variables, the RAID controller circuitry being comprised in a circuit card, the domain variables comprising block size of a frame payload portion, number of logical block addresses in a given domain, and RAID stripe size; discovering at least one data block comprising logical block address information; and executing a mapping operation by logical block address mapping circuitry comprised in the circuit card, the mapping operation being to translate the logical block address information from a first domain to a second domain and being based upon the domain variables, the first domain comprising a logical domain, the second domain comprising a physical domain; and disabling, on an input/output transaction basis, the logical block address mapping circuitry, while continuing to permit operation of the RAID controller circuitry.
