Abstract
A RAID parity data generation offload system includes a RAID storage controller device that determines that a RAID parity data storage device loading for a RAID parity data storage device exceeds a loading threshold, and then generates and transmits a RAID parity data generation offload command associated with a RAID parity data update required in response to a RAID primary data update. A first RAID primary data storage device receives the RAID parity data generation offload command, and then retrieves current parity data from the RAID parity data storage device, and performs an XOR operation using the current parity data, current primary data, and updated primary data associated with the RAID primary data update in order to generate updated parity data. The first RAID primary data storage device then provides the updated parity data for storage on the RAID parity data storage device in place of the current parity data.
