DATA PROCESSING METHOD, REMOTE DIRECT MEMORY ACCESS NETWORK CARD, AND DEVICE

摘要

The present application provides a data processing method, an RNIC, and a device. The method comprises: a first RNIC receiving a remote direct memory access (RDMA) write request sent by a second RNIC, the RDMA write request comprising first data and a data persistence flag, the data persistence flag being used to indicate that the first data is data to be persisted; according to the RDMA write request, the first RNIC sending a DMA write request to a first processor, to instruct the first processor to write the first data into a first device, the first RNIC and the first processor belonging to the first device, the second RNIC belonging to a second device, and the two devices communicating on the basis of an RDMA approach; and according to the data persistence flag, the first RNIC determining that the first data is the data to be persisted, and the first RNIC instructing the first processor to save the first data into a non-volatile memory of the first device. Thus, the present invention reduces the load of an RDMA network during remote memory persistence.
