University of Florida Research Foundation, Inc., Gainesville, FL, has been assigned a patent (9,772,794) developed by Li, Tao, Gainesville, FL, and Zhou, Ruijin, Sunnyvale, CA, for a "method and apparatus for big data cloud storage resource management."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A system and method for storage resource management using copy-on-write/read snapshots to redirect the I/O requests without moving the virtual disk is disclosed herein. The system includes storage pools, a virtualized server, and a centralized data center management server. The virtualized server includes a base disk and a virtualized disk having a copy-on-write and a copy-on-read snapshot process responsive to an I/O request that merges a previous snapshot stored on a first one of the plurality storage pools with the base disk stored on a second one of the plurality of storage pools, while it fetches a new snapshot to be stored on a third one of the plurality of storage pools from the previous snapshot or the base virtual disk. The system includes a performance model, employing an exponentially weighted moving average with an adjustable sliding window."

The patent application was filed on June 6, 2016 (15/174,657).
