Data reconstruction in distributed storage system with key-based addressing
By Francis Pelletier | September 9, 2016 at 3:04 pmDatrium, Inc., Sunnyvale, CA, has been assigned a patent (9,417,955) developed by Patterson, III, R. Hugo, Los Altos, CA, Wang, Zhe, Cupertino, CA, and Huang, Mark L., Seattle, WA, for a “data reconstruction in distributed data storage system with key-based addressing.“
The abstract of the patent published by the U.S. Patent and Trademark Office states: “In a Distributed Virtual Array data storage system, data chunks making up data containers are stored in a key order in storage devices according to layouts specified in a layout data structure. When any of the storage devices becomes inaccessible, the storage devices iteratively return, in storage order, their stored chunks. Chunks belonging to the same container are identified and, if that container had a chunk in the inaccessible storage device, are used to reconstruct the inaccessible chunk. The chunks of the container are then stored according to an updated layout. The keys are independent of physical storage locations.“
The patent application was filed on October 22, 2014 (14/520,610).
