Abstract: This application discloses a network interface card, a controller, a storage apparatus, and a packet sending method, and relates to the storage field to reduce a delay of an RDMA read operation. The network interface card includes: a second processing module, configured to: in response to a doorbell signal of a first controller, obtain a first work queue element WQE from a first send queue SQ corresponding to the first controller, where the doorbell signal indicates that there is a to-be-sent message in a storage space to which at least one WQE points in the first SQ, the first WQE includes indication information, and the indication information indicates a type of a first remote direct memory access RDMA packet scheduled by the first WQE; and a second transceiver module, configured to.

Abstract: The technology of this application relates to a network interface card. The network interface card includes a parser and at least one shared connector. The parser receives a first SEND message that is from a host client and that corresponds to a first QP connection, and distributes the first SEND message to a first shared connector in the at least one shared connector. The first SEND message includes an RDMA operation command. The first shared connector obtains NVME information that is sent to a first controller and that corresponds to the first QP connection. The first shared connector interacts with a second controller when a disconnection event of a link between the first shared connector and the first controller is detected. The first shared connector obtains a WQE from the second controller. The first shared connector sends a first RDMA message corresponding to the first QP connection to the host client based on the WQE.
