DDN Assigned Patent

DataDirect Networks, Inc., Chatsworth, CA, has been assigned a patent (9,639,457) developed by Piszczek, Michael J., Laurel, MD, Cope, Jason M., Harker, William J., Columbia, MD, Fugini, Thomas E., Mt. Airy, MD, and Uppu, Pavan Kumar, Laurel, MD, for a “data storage system and method for data migration between high-performance computing architectures and data storage devices using storage controller with distributed XOR capability.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “In the data storage system the storage area network performs XOR operations on incoming data for parity generation without buffering data through a centralized RAID engine or processor. The hardware for calculating the XOR data is distributed to incrementally calculate data parity in parallel across each data channel and may be implemented as a set of FPGAs with low bandwidths to efficiently scale as the amount of storage memory increases. A host adaptively appoints data storage controllers in the storage area network to perform XOR parity operations on data passing therethrough. The system provides data migration and parity generation in a simple and effective matter and attains a reduction in cost and power consumption.“

The patent application was filed on December 20, 2012 (13/722,171).
