Quantum Assigned Patent

Quantum Corporation, San Jose, CA, has been assigned a patent (9,727,437) developed by Reinart, John, Roseville, MN, for a “dynamically controlling erasure code distribution in an object store.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Example apparatus and methods monitor conditions in an object storage system. The conditions monitored may include a load balance measure in the system, a capacity balance measure in the system, a fault tolerance measure in the system, or a usage pattern measure in the system. A distribution plan or redistribution plan for storing or moving erasure codes in the object storage system may be determined based on the conditions. The distribution plan or the redistribution plan for the erasure codes may be updated dynamically in response to changing conditions in the object storage system. The distribution or redistribution may depend on a weighted combination of the load balance measure, the capacity balance measure, the fault tolerance measure, or the usage pattern measure so that responding to one sub-optimal condition, (e.g., load imbalance) does not create a different sub-optimal condition, (e.g., unacceptable fault tolerance).“

The patent application was filed on February 18, 2014 (14/183,310).
