Abstract
A method and system for rebuilding a Redundant Array of Independent Disks (“RAID”), the system comprising a RAID engine comprising one or more processing devices that facilitate packet communications with a plurality of storage devices, the packet communications including Read/Write-Rebuild opcodes and settings that prioritize read and write requests associated with a RAID rebuild of the plurality of storage devices, the Read/Write-Rebuild opcodes including rebuild input/output (“IO”) read requests that read good portions of data and parity information from a set of the plurality of storage devices, and rebuild IO write requests that write data to a new one of the plurality storage devices wherein the written data includes data that is reconstructed by the RAID engine based on the data and the parity information.
