An intelligent cooling control system and control method for a server

Abstract

Disclosed are an intelligent heat radiation control system and method. The intelligent heat radiation control system is arranged in a Godson server, a signal input end of the BMC (baseboard management controller) chip is connected with temperature sensors through an I2C multichannel switcher, a signal output end of the same is respectively connected with a watchdog and a hardware monitor, an output end of the hardware monitor is connected with fans through a selector switch chip, an output end of the watchdog is connected with a switch enabling signal input end of the selector switch chip, and the signal input end of the BMC chip is connected with pins. The intelligent heat radiation control method includes programming heat radiation control programs, setting level of each pin, detecting the level of the pins and calling the corresponding heat radiation control programs by the BMC chip, outputting low level by the watchdog to control disconnection of an access of the BMC chip and the control signal input ends of the fans, outputting high level by the selector switch chip to control all fans to operate in full speed, and reading temperature of measure points of the temperature sensors and adjusting rotation speed of the fans by the BMC chip. The intelligent heat radiation control system and method can intelligently identify types of server crates and automatically call heat radiation strategies corresponding to servers.

Description

technical field [0001] The invention relates to a heat dissipation control system. In particular, it relates to an intelligent heat dissipation control system and control method for a server capable of intelligently identifying the type of a server chassis and automatically invoking a heat dissipation strategy corresponding to the server. Background technique [0002] An excellent server cooling system design should first ensure the maximum thermal power consumption requirements of each component, and secondly, on this basis, it can adapt to the maximum and intelligently reduce the fan speed to achieve the purpose of energy saving and noise reduction. [0003] At present, most server cooling systems can basically automatically test the temperature state inside the server and intelligently adjust the fan speed from time to time. However, most of the solutions only design cooling systems for a certain server, and seldom involve cooling solutions for different types of servers...

AI Technical Summary

Problems solved by technology

The disadvantage of this method is that each server corresponds to a cooling control software version, which brings difficulties to product management, increases the types and difficulties of material control, and is prone to errors

[0005] On the other hand, the commonly used heat dissipation control methods are based on the fact that the heat dissipation control main chip can work normally, without considering the failure of the heat dissipation control main chip
