1. RDMA+NVM remote persistence

    Problem Due to RDMA NIC implementation, RNIC doesn’t have remote persistent flush primitives. So one-sided write data from clients will write to the volatile cache on RNIC first and then RNIC directly sends ACK back before writing data to PM. As a result, a power loss will break remote data persistence easily.
