Abstract

The invention provides a controller cluster of a storage system, a message transmission method of the controller cluster and a readable storage medium, and belongs to the technical field of block chains. The message transmission method comprises: a window layer of an initiator node activating a communication path of a driver layer, and an exchange layer newly building an initiator instance and sending a request instruction to a response end node through the driver layer; the communication layer of the response end node newly building a response end instance according to the received sending request instruction, the window layer updating the serial number, and the communication layer calling a channel to send the message of the message queue to the communication layer of the initiating endnode from the driving layer; and the communication layer of the initiating end node receiving the message through the driving layer, transmitting the message to the window layer after the message is received, and notifying the window layer to upload the message to the application module.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a controller cluster of a storage system, a message transmission method thereof, and a readable storage medium. Background technique [0002] In the storage system, in order to achieve high reliability, a group of independent storage controllers join together to form a cluster, which provides external services as a single system. Each storage controller in the cluster is a node. Nodes in a cluster can communicate not only with other nodes in the cluster, but also with nodes in other clusters in the local area network. The traditional computer communication method is represented by TCP / UDP. The former uses a connection-oriented protocol to provide reliable services without error, packet loss, or repetition, and arrives in order. The connection request is more complicated and the transmission efficiency is low. The latter adopts a connectionless protocol, which is t...
