Datrium Assigned Patent
Alternate storage arrangement in distributed storage system with key-based addressing
By Francis Pelletier | January 7, 2020 at 2:16 pmDatrium, Inc., Sunnyvale, CA, has been assigned a patent (10,514,982) developed by Wang, Zhe, Cupertino, CA, Patterson, R. Hugo, Los Altos, CA, and Huang, Mark L., Seattle, WA for an “alternate storage arrangement in a 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 and identified by keys, which are independent of physical storage locations, are written in storage devices according to layouts specified in a layout data structure. When any of the storage devices becomes inaccessible, the chunks nominally designated to be written in the inaccessible storage devices are instead written to alternate devices. Information indicating writing to an alternate device may be included in or along with such chunks so as to make them easily identifiable during later reconstruction or re-writing to the intended storage device when it again becomes available.”
The patent application was filed on December 12, 2014 (14/568,700).
