ScaleFlux Assigned Patent

ScaleFlux, Inc., San Jose, CA, has been assigned a patent (10,044,500) developed by Zhong, Hao, Los Gatos, CA, Sun, Fei, Irvine, CA, and Liu, Yang, Milpitas, CA, for an “error correction coding redundancy based data hashing.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Storage infrastructures and methods that generate hash values based on error correction codes. A system is provided that includes: a code retrieval system implemented on a host having logic for issuing a redundancy read command to a storage system to retrieve a redundancy code for an identified data block, and a hashing system implemented on the host for hashing the redundancy code to generate a hash value based on the redundancy code. A storage system is also provided that includes: a memory for storing data blocks and associated redundancy codes, and a controller having: an input/output for receiving a hash value read command for a specified data block from a host and returning a hash value, a decoding system that extracts a redundancy code associated with the specified data block, and an in-memory hashing system for computing a hash operation on the redundancy code.”

The patent application was filed on May 13, 2016 (15/154,035).
