Abstract:
Methods and systems for a storage environment are provided. For example, one method includes receiving a request from a storage server at an offload engine for reconstructing data lost due to a failed storage device of a parity group having a plurality of storage devices; retrieving data and parity by the offload engine from the parity group storage devices that are operational; determining by the offload engine XOR of the retrieved data and parity; presenting XOR of data and parity by the offload engine to the storage server with context information associated with the retrieved data; and reconstructing lost data by the storage server using the XOR of data and parity and the context information provided by the offload engine.
