Quantum Assigned Two Patents

Media allocation in partitioned removable media storage library
Quantum Corporation, San Jose, CA, has been assigned a patent (9,311,147) developed by Wideman, Roderick B., Shakopee, MN, for a “method for media allocation in a partitioned removable media storage library.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”An open systems based media storage library system, (10) for use by one or more hosts, (5) includes a first hosted partition, (12A) and a pool partition, (14). The first hosted partition, (12A) can be accessed by one of the hosts, (5). Additionally, the first hosted partition, (12A) includes a plurality of first hosted resources, (16, 18). The plurality of first hosted resources, (16, 18) can include a plurality of first hosted storage slots, 16) and a plurality of first hosted storage media, (18). The plurality of first hosted storage slots, (16) includes one or more first physical storage slots, (16P) and one or more first logical storage slots, (16L). The plurality of first hosted storage media, (18) are positioned within the first physical storage slots, (16P). The pool partition, (14) is inaccessible by any of the hosts, (5). The pool partition, (14) includes a plurality of pool resources, (20, 22). One of the plurality of pool resources, (20, 22) is selectively assigning to the first hosted partition, (12A).“

The patent application was filed on October 20, 2010 (12/908,732).

Combined asynchronous and synchronous fountain code storage in object store
Quantum Corporation, San Jose, CA, has been assigned a patent (9,304,852) developed by Reinart, John, Roseville, MN, for a “combined asynchronous and synchronous fountain code storage in an object store.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Example apparatus and methods produce a set of rateless erasure codes, (e.g., fountain codes) for a file stored in a primary data store, (e.g., hard drive) or in an archive system. The archive system may store the file in a redundant array of independent disks, (RAID). A first subset of the rateless erasure codes are stored in an object storage using a synchronous protocol. A second subset of rateless erasure codes are stored in the object storage using an asynchronous protocol. The object storage system may inform the archive system when desired redundancy has been achieved or when desired redundancy has been lost. The archive system may buffer rateless erasure codes before providing the codes to the object storage to improve performance. A failure in the archive system or object storage system may be mitigated by retaining the file in the primary data store until the desired redundancy is achieved.“

The patent application was filed on February 13, 2014 (14/179,726).
