Abstract
In a network storage device that includes a plurality of data storage drives, error correction and/or recovery of data stored on one of the plurality of data storage drives is performed cooperatively by the drive itself and by a storage host that is configured to manage storage in the plurality of data storage drives. When an error-correcting code (ECC) operation performed by the drive cannot correct corrupted data stored on the drive, the storage host can attempt to correct the corrupted data based on parity and user data stored on the remaining data storage drives. In some embodiments, data correction can be performed iteratively between the drive and the storage host. Furthermore, the storage host can control latency associated with error correction by selecting a particular error correction process.
