A method for implementing NVMe over fabrics includes generating, by a terminal, a NVMe instruction, where the NVMe instruction indicates a data read operation or a data write operation. The method further includes sending, by the terminal by using remote direct memory access (RDMA), the NVMe instruction to a submission queue (SQ) that is stored in a server. When the NVMe instruction indicates the data read operation, the method includes receiving, by the terminal by using the RDMA, to-be-read data sent by the server. Alternatively, when the NVMe instruction indicates the data write operation, the method includes sending, by the terminal, to-be-written data to the server by using the RDMA. The method further includes 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 completion queue (CQ) that is set in the terminal.
