Here Data Technology Assigned Patent

Here Data Technology, Shenzhen, China, has been assigned a patent (11,188,404) developed by Zhang, Jingyao, Zhu, Jian, and Hao, Bin, Guangdong, China, for “methods of data concurrent recovery for a distributed storage system and storage medium thereof.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Disclosed is a method of data concurrent recovery for a distributed storage system, that is, a method for synchronous repair of multiple failed nodes with a minimum recovery bandwidth when a node in a distributed storage system fails. First an assistant node is selected to get helper data sub-block, then the repair matrix related to the data block stored in the node to be repaired is constructed, and finally the lost data block is reconstructed by multiplying the repair matrix and the helper data helper data sub-block, the missing data block is reconstructed by decoding, wherein the node to be recovered includes all failed systematical nodes, or all or partly failed parity nodes. The method is applicable to concurrently recover multiple failed nodes at minimal recovery bandwidth, and the nodes to be recovered are selected according to the demand to reduce the recovery bandwidth as much as possible.”

The patent application was filed on July 10, 2018 (17/059,439).
