Abstract
This application discloses a network interface card so as to improve reliability of a storage apparatus using an RDMA network and improve storage access performance of a single QP connection. A network interface card includes a parser and at least one shared connector, where the parser is configured to distribute a received first remote direct memory access RDMA packet to a first shared connector in the at least one shared connector; and the first shared connector is configured to establish a QP connection to a peer network device, and determine a first queue pair QP corresponding to a first controller based on the first RDMA packet, so as to implement communication with the first controller, where the first shared connector is separately connected to a plurality of controllers including the first controller, and one QP corresponding to each of the plurality of controllers corresponds to the first shared connector.
