Storage controller node communication method, device and equipment and storage medium

Abstract

The invention discloses a storage controller node communication method, which comprises the following steps of: respectively distributing ports for a plurality of communication links between two storage controller nodes in a storage controller to obtain port information corresponding to the plurality of communication links; wherein the number of the plurality of communication links is greater than2; acquiring communication data, and judging whether a target communication link exists by utilizing the port information; wherein the target communication link is an idle communication link; if thetarget communication link exists, using the target communication link to transmit the communication data; according to the method, a plurality of communication links are established between two storage controller nodes, and when communication data is transmitted, port information of the plurality of communication links is utilized to determine a target communication link and transmit the communication data; by utilizing the method, the data transmission rate can be improved, and the problem of relatively low reliability of the storage controller is solved; in addition, the invention also provides a storage controller node communication device, equipment and a computer readable storage medium, which also have the above beneficial effects.

Description

technical field [0001] The present invention relates to the technical field of storage controllers, in particular to a storage controller node communication method, a storage controller node communication device, a storage controller node communication device, and a computer-readable storage medium. Background technique [0002] A storage controller (storage controller) is a key component of a storage system and is used to perform data transmission tasks. In order to ensure the stability of the storage controller, most of the current storage controllers adopt a dual-control scheme, that is, a storage controller is composed of two storage controller nodes, and the two storage controller nodes serve as backups for each other. When , another node can still complete the task independently. Two storage controller nodes use an NTB (NonTransparent Bridge, non-transparent bridge) link as a communication link to provide data transmission for the two nodes to back up each other's dat...
