Problems solved by technology

[0003] However, due to the need to intrude into the user system, there are requirements for the operating system type, version, and system resources of the user system. Not only is it difficult to implement, but it will also cause additional data transmission overhead and affect the overall performance of the storage cluster.

Abstract

The embodiment of the invention provides a data transmission method and device and a distributed storage system. The data transmission method applied to a switch comprises the steps of, in response to a received data packet sent by a request end, judging whether the data packet is a storage protocol data packet or not; if yes, finding a corresponding target storage node in a preset I / O request routing rule by utilizing storage message characteristics of the storage protocol data packet, wherein the preset I / O request routing rule comprises a corresponding relation between storage characteristic information of data and target storage node information; and issuing the storage protocol data packet to the target storage node, so that the target storage node processes the storage protocol data packet, and synchronizes control information of the storage protocol data packet to other storage nodes of the distributed storage system.

Description

technical field [0001] The embodiments of this specification relate to the field of computer technology, and in particular, to a data transmission method. One or more embodiments of this specification also relate to a data transmission device, a distributed storage system, a computing device, and a computer-readable storage medium. Background technique [0002] In a distributed storage system, data access services are generally distributed to different storage nodes based on a certain strategy. Based on the distributed storage system, I / O needs to be sent to the corresponding storage nodes according to the decentralized strategy. At present, a supporting dedicated client or customized multi-path software is usually installed in the user system, and the storage node is directly selected at the source of the user system and delivered. The data packet is sent to the corresponding storage node. [0003] However, due to the need to intrude into the user system, there are requir...
