Network interface card, storage apparatus, and packet receiving method and sending method

A network interface card, comprising a scheduler and at least one shared connector, wherein

• the scheduler is configured to select, from a plurality of queue pairs QPs of a plurality of controllers in position, a second QP that is corresponding to a second shared connector and has a message to be sent, wherein the second shared connector is one of the at least one shared connector;
• the second shared connector is configured to establish a QP connection to a peer network device, and send, to a host client, a message in a storage space corresponding to the second QP in a form of a second remote direct memory access RDMA packet;
• and the second shared connector is separately connected to the plurality of controllers, and one QP corresponding to each of the plurality of controllers is corresponding to the second shared connector.

A storage apparatus, comprising a network interface card (NIC) and a plurality of controllers, wherein the network interface card is separately connected to each of the plurality of controllers, and the network interface card comprise a parser and at least one shared connector, wherein

• the parser is configured to distribute a received first RDMA packet to a first shared connector in the at least one shared connector;
• and
• the storage apparatus is configured to establish a QP connection to a peer network device via the first shared connector, and determine a first QP corresponding to a first controller based on the first RDMA packet, so as to implement communication with the first controller, wherein the first shared connector is separately connected to a plurality of controllers comprising the first controller, and one QP corresponding to each of the plurality of controllers is corresponding to the first shared connector.
