Performing data writes in parity protected redundant storage arrays

A system for performing a data write operation in a storage array utilizing a Redundant Array of Independent Disks (RAID) configuration with parity information, comprising:

• means for calculating a first physical disk identifier, a physical Logical Block Address (LBA), a data size, and a span identifier from the data write operation;
• means for creating a first request command frame for retrieving an existing data block from the storage array, the first request command frame including at least one of the calculated first physical disk identifier, the calculated physical LBA, the calculated data size, and the calculated span identifier;
• means for calculating at least one second physical disk identifier from the data write operation;
• means for creating at least one second request command frame for retrieving at least one existing parity data block from the storage array, the at least one second request command frame including the calculated at least one second physical disk identifier and at least one of the calculated physical LBA, the calculated data size, or the calculated span identifier;
• means for calculating at least one new parity data block utilizing the existing data block, a new data block, and the at least one existing parity data block;
• means for altering the first request command frame to operate as a first write command frame;
• and
• means for altering the at least one second request command frame to operate as at least one second write command frame.

A non-transitory computer-readable medium having computer-executable instructions for performing a method for performing a data write operation in a storage array utilizing a Redundant Array of Independent Disks (RAID) configuration with parity information, the method comprising:

• calculating a first physical disk identifier, a physical Logical Block Address (LBA), a data size, and a span identifier from the data write operation;
• creating a first request command frame for retrieving an existing data block from the storage array, the first request command frame including at least one of the calculated first physical disk identifier, the calculated physical LBA, the calculated data size, and the calculated span identifier;
• calculating at least one second physical disk identifier from the data write operation;
• creating at least one second request command frame for retrieving at least one existing parity data block from the storage array, the at least one second request command frame including the calculated at least one second physical disk identifier and at least one of the calculated physical LBA, the calculated data size, or the calculated span identifier;
• calculating at least one new parity data block utilizing the existing data block, a new data block, and the at least one existing parity data block;
• altering the first request command frame to operate as a first write command frame;
• and
• altering the at least one second request command frame to operate as at least one second write command frame.
