Tsinghua University Assigned Patent

Tsinghua University, Beijing, China, has been assigned a patent (10,346,245) developed by Zhang, Guangyan, and Zheng, Weimin, Beijing, China, for “data storage system and data storage method.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “The data storage system and the data storage approach based on redundant arrays of independent disks, (RAID) is provided. The storage system includes: an RAID controller, and a storage device subsystem. This storage device subsystem includes a plurality of first physical storage devices for data storage and a plurality of second physical storage devices for parity storage. First physical storage devices are divided into a plurality of sets of first disks which are independent from each other. The data accesses to different sets of first disks will not interfere with each other. These second disks are shared by all the sets of first disks. The RAID controller stores data in each set of first disks and stores parity information in multiple shared second disks by the RAID mechanism. The storage system combines the parity from different RAID volumes into one shared set and this improves the performance and reliability of the whole storage system.”

The patent application was filed on December 9, 2014 (15/533,924).
