NVME NETWORKED STORAGE IMPLEMENTATION METHOD, TERMINAL, SERVER, AND SYSTEM

摘要

The present invention relates to the field of data transmission, and in particular, to a method for implementing NVMe over fabrics, a terminal, a server, and a system. The method in embodiments of the present invention includes: generating, by a terminal, a non-volatile memory express NVMe instruction; sending, by the terminal, the NVMe instruction to an SQ in a server by using RDMA; when the NVMe instruction indicates a data read operation, receiving, by the terminal by using the RDMA, to-be-read data sent by the server; or when the NVMe instruction indicates a data write operation, sending, by the terminal, to-be-written data to the server by using the RDMA; receiving, by the terminal, an NVMe completion instruction sent by using the RDMA by the server; and writing, by the terminal, the NVMe completion instruction into a CQ in the terminal. In solutions of the embodiments of the present invention, the RDMA and an NVMe are combined, a CQ in the NVMe is set in the terminal, and an SQ in the NVMe is set in the server, so that a quantity of interactions between the terminal and the server in one NVMe operation can be decreased and CQ processing complexity can be reduced, thereby improving NOF performance.
