Abstract

The embodiments of the invention relate to the technical field of communications, and particularly relate to a data writing method and a relevant device for reducing the time delay of the data writing process. In the embodiments, after a server network card receives a data writing request command sent by a client server, on the one hand, the server network card directly analyzes the data writing request command, and returns a first data reading command to a client processor, so as to store data to be written into a storage area of the server network card; and on the other hand, the server network card transmits the data writing request command to the server, so that when a second data reading command returned by the server is received, the data to be written can be directly transmitted from the storage area of the server network card to a storage area pointed by a second target address.

Description

technical field [0001] The embodiment of the present invention relates to the communication field, and in particular to a data writing method and a server-side network card. Background technique [0002] figure 1 It exemplarily shows a structural diagram of a connection relationship between a client (called Initiator in English) and a server (called Target in English) in the prior art. Such as figure 1 As shown, the client processor 111 (referred to as Initiator X86 in English) is connected to the Remote Direct Memory Access (RDMA) Converged Ethernet (RDMA over Converged Ethernet, ROCE) through the client network card 112, and through The ROCE is connected to the switch 113 , and the client processor 111 is connected to the storage area 121 of the client. The server-side processor 115 (called Target X86 in English) is connected to the server-side network card 114, and the server-side network card 114 is connected to the switch 113 by the NVME protocol (NVMEover Fabric, re...
