Qnap Assigned Patent

Qnap Systems, Inc., New Taipei, Taiwan, has been assigned a patent (11544012) developed by Hsu; Chin-Hsing, New Taipei, Taiwan, for “distributed storage system and data synchronization method applied thereto.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A distributed storage system and a data synchronization method are used with a network. The system includes a first network host and a second network host. A first file system directly writes data generated by the first network host into a first software-simulated persistent memory. The data in the first software-simulated persistent memory is stored into a first remote block device and cached, respectively. The cached data is stored into a first persistent storage by asynchronous writeback mechanisms. The first remote block device transmits the received data to the second software-simulated persistent memory through the network. The data transmitted to the second software-simulated persistent memory is cached, and the cached data is stored into a second persistent storage by asynchronous writeback mechanisms. The second network host replaces the first network host to provide services when the first network host is out of service.”

The patent application was filed on 2021-10-13 (17/500069).
