Quantum Assigned Two Patents

Efficient high/low energy zone solid state device data storage
Quantum Corporation, San Jose, CA, has been assigned a patent (9,846,613) developed by Arslan, Suayb, Irvine, CA, and Goker, Turguy, Vista, CA, for an “efficient high/low energy zone solid state device data storage.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Methods and apparatus associated with storing data in high or low energy zones are described. Example apparatus include a data storage system, (DSS) that protects a message using an erasure code, (EC). A location in the DSS may have an energy efficiency rating or a latency. Example apparatus include circuits that produce EC encoded data that has a likelihood of use, that select a location to store the EC encoded data in the DSS based on the energy efficiency rating, the latency, or the likelihood of use, that store the EC encoded data in the location, and that compute an order of retrieval for EC encoded data stored in the location. The order of retrieval may be based on the energy efficiency rating or the latency. The EC encoded data may also have a priority based on the number of erasures for which the EC corrects.”

The patent application was filed on January 26, 2016 (15/006,403).

Clustered storage network
Quantum Corporation, San Jose, CA, has been assigned a patent (9,804,804) developed by Maroney, John E., and Chakravarty, Tridib, Irvine, CA, for a “clustered storage network.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A data storage network is provided. The network includes a client connected to the data storage network; a plurality nodes on the data storage network, wherein each data node has two or more RAID controllers, wherein a first RAID controller of a first node is configured to receive a data storage request from the client and to generate RAID parity data on a data set received from the client, and to store all of the generated RAID parity data on a single node of the plurality of nodes.”

The patent application was filed on March 10, 2014 (14/202,908).
