  • Back-annotation in storage-device array
    Patent number: 7644303
    Abstract: In one embodiment, a method for reading data from a storage-device array including three or more storage devices. The array has a plurality of sector levels, each sector level containing one sector on each storage device in the array at corresponding addresses across the storage devices. Each sector level includes (i) parity data stored on a first storage device and (ii) information stored on the two or more remaining storage devices. The parity data for a current sector level is generated from the information stored at the current sector level on the remaining storage devices.
