Abstract
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.
