Abstract
A RAID system includes a storage enclosure comprising a plurality of independent data storage devices. A processor is associated with the storage enclosure. The processor is configured for processing data for the plurality of storage devices of the storage enclosure. The processor is configured to receive a request to read intermediate XOR data based on data stored in two or more of the plurality of storage devices of the storage enclosure. The processor is further configured to read data from each of the two or more storage devices in response to receiving the request. The processor is configured to determine intermediate XOR data based on the data read from the two or more storage devices of the storage enclosure. The intermediate XOR data may be provided to a RAID storage controller and may be used in an XOR-based recovery process.
