The Regents of University of California Assigned Patent

The Regents of the University of California, Oakland, CA, has been assigned a patent (10,187,088) developed by Jafarkhani, Hamid, and Hajiaghayi, Mahdi, Irvine, CA, for a “cost-efficient repair for storage systems using progressive engagement“.

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”An apparatus or method for minimizing the total accessing cost, such as minimizing repair bandwidth, delay or the number of hops including the steps of minimizing the number of nodes to be engaged for the recovery process using a polynomial-time solution that determines the optimal number of participating nodes and the optimal set of nodes to be engaged for recovering lost data, where in a distributed database storage system, for example a dynamic system, where the accessing cost or even the number of available nodes are subject to change results in different values for the optimal number of participating nodes. An MDS code is included which can be reused when the number of participating nodes varies without having to change the entire code structure and the content of the nodes”.

The patent application was filed on April 17, 2015 (14/689,870).
