Xyratex Technology Limited, Havant, Great Britain, has been assigned a patent (9,405,623) developed by Taranta, II, Eugene Mathew, Casselberry, FL, for a “method of, and apparatus for, layout rectification of erasure encoded storage systems.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “There is provided a method of recovering configuration metadata from an erasure encoded RAID array. The RAID array includes raw data including a plurality of codewords encoded using Reed-Solomon encoding. The codewords include message data and checksum data, and the configuration metadata includes parameters relating to the layout of the RAID array. The method includes reading, from the RAID array, raw data including message data and checksum data. Then a set of linear equations are defined using the message data and checksum data. The linear equations are then solved and then, from the solved linear equations, one or more parameters relating to the layout of the RAID array are determined.“

The patent application was filed on September 25, 2013 (14/037,075).
