Regents of University of Minnesota Assigned Patent

Regents of the University of Minnesota, Minneapolis, MN, has been assigned a patent (11513898) developed by Elyasi, Mehran, Falcon Heights, MN, and Mohajer, Soheil, Plymouth, MN, for “exact repair regenerating codes for distributed storage systems.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A distributed storage system includes a plurality of nodes comprising a first node, wherein a total number of nodes in the distributed storage system is represented by n, wherein a file stored in the distributed storage system is recovered from a subset of a number of nodes represented by k upon a file failure on a node in the distributed storage system, and wherein a failed node in the plurality of nodes is recovered from a number of helper nodes of the plurality of nodes represented by d. Upon detecting a failure in the first node, each helper node of the number of helper nodes is configured to determine a repair-encoder matrix, multiply a content matrix by the repair-encoder matrix to obtain a repair matrix, extract each linearly independent column of the repair matrix, and send the linearly independent columns of the repair matrix to the first node.”

The patent application was filed on 2020-06-19 (16/906505).
