Abstract

The present invention discloses a network communication method, apparatus, device, and medium for a multi-controller storage server, relating to the field of network communication technology, including: obtaining a target serial port instruction initiated for a target controller node; executing the target serial port instruction to establish a communication transmission link between a target global shared network communication system and the target management system using each local shared network communication system corresponding to the target management system; if the communication transmission link cannot be successfully established, selecting another global shared network communication system from at least two global shared network communication systems as the current new target global shared network communication system, and re-jumping to the step of obtaining the target serial port instruction initiated for the target controller node through the serial port expansion card of the target global shared network communication system. The present invention improves the communication reliability of the multi-controller storage server by optimizing the communication sharing and redundant design management between the controller nodes in the multi-controller storage server.
