NETWORK INTERFACE CARD, MESSAGE TRANSCEIVING METHOD, AND STORAGE APPARATUS

WIPO Patent Application WO/2022/179417

A1

The present application relates to the field of storage. Disclosed are a network interface card, a message transceiving method, and a storage apparatus, which are used for preventing the disconnection of a QP connection when a certain controller fails, thereby improving the reliability of the storage apparatus. The network interface card comprises: a parser and at least one shared connector. The parser receives a first SEND message that is from a host client and corresponds to a first QP connection, and distributes the first SEND message to a first shared connector in the at least one shared connector, wherein the first SEND message comprises an RDMA operation command. The first shared connector obtains, according to the RDMA operation command and the current stage of an RDMA operation, NVME information that is sent to a first controller and corresponds to the first QP connection, interacts with a second controller upon detecting a disconnection event of a link with the first controller, such that the second controller acquires the NVME information, acquires a WQE from the second controller, wherein the WQE is obtained by the second controller according to the NVME information, and according to the WQE, sends, to the host client, a first RDMA message corresponding to the first QP connection.
