Quantum Assigned Two Patents

Joint de-duplication-erasure coded distributed storage
Quantum Corporation, San Jose, CA, has been assigned a patent (10,853,187) developed by Arslan, Suayb S., Goker, Turguy, Irvine, CA, and Wideman, Roderick B., Shakopee, MN, for a “joint de-duplication-erasure coded distributed storage.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Methods and apparatus deduplicate and erasure code a message in a data storage system. One example apparatus includes a first chunking circuit that generates a set of data chunks from a message, an outer precoding circuit that generates a set of precoded data chunks and a set of parity symbols from the set of data chunks, a second chunking circuit that generates a set of chunked parity symbols from the set of parity symbols, a deduplication circuit that generates a set of deduplicated data chunks by deduplicating the set of precoded chunks or the set of chunked parity symbols, an unequal error protection (UEP) circuit that generates an encoded message from the set of deduplicated data chunks, and a storage circuit that controls the data storage system to store the set of deduplicated data chunks, the set of parity symbols, or the encoded message.”

The patent application was filed on February 26, 2019 (16/285,320).

Global storage solution with logical cylinders and capsules
Quantum Corporation, San Jose, CA, has been assigned a patent (10,846,177) developed by Saliba, George, Boulder, CO, for a “global storage solution with logical cylinders and capsules.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Example apparatus and methods control a data storage system to store data in a self-describing logical data storage capsule using a logical cylindrical recording format. Example apparatus and methods assign a searchable, globally unique identifier to the capsule and associate the globally unique identifier with a user. The logical data storage capsule is migrated from a first data storage medium to a second data storage medium without translating or reformatting the data storage capsule. The data storage capsule contains information describing to a data storage device how to migrate the capsule without translating or reformatting the data storage capsule. Example apparatus and methods dynamically select an error correction approach for storing data in the data storage capsule, de-duplicate, and encrypt the data storage capsule. The data storage capsule may be local, or may be part of a cloud-based storage system.”

The patent application was filed on October 28, 2019 (16/665,756).
