Data processing method, device and equipment based on network card and readable storage medium

The invention discloses a data processing method, device and equipment based on a network card and a readable storage medium, and the method comprises the steps: dividing an initial block storage message into N unit storage messages with a target storage length based on the unit storage length, generating a redundancy check value of each unit storage message, generating N access block storage messages according to the N unit storage messages and the N redundancy check values, performing message format conversion on the unit storage messages in the N access block storage messages through a remote direct access protocol to obtain N unit network messages, and generating N transmission network messages according to the N unit network messages and the N redundancy check values; the storage length of the N unit network messages is equal to the target storage length; and sending the N transmission network messages to a second device, so that the second device writes the N transmission network messages into a node st
