Datrium, Inc., Sunnyvale, CA, has been assigned a patent (10,146,684) developed by Hsu, Windsor, San Jose, CA, and Patterson, R. Hugo, Los Altos, CA, for a “distributed data parallel method for reclaiming space.

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Techniques for copying forward live data within storage regions used by a file system to new storage regions are provided. Storage regions refer to ranges of persistent storage within a storage medium. One or more live-clump-identifying workers identify a set of live-clump-references. The live-clump references are references to live clumps that belong to live objects. Live clumps represent a unit of data. After identifying the set of live-clump-references, one or more container-identifying workers identify a set of storage regions that contain clumps that correspond to the set of live-clump references. After identifying the set of storage regions corresponding to the set of live-clump-references, a plurality of copy-forward task workers perform copy-forward operations on the set of storage regions to copy live data to new storage regions.

The patent application was filed on October 24, 2016 (15/332,790).
