An intelligent heat dissipation control method applied to blade servers

Abstract

The invention provides an intelligent heat-radiation control method applied to a blade server. A system comprises blade calculation nodes, fan systems and a system management center SMC, wherein the blade calculation nodes are connected with the system management center SMC through an IPMI protocol, and the system management center SMC reads current calculation load and temperature from the blade nodes through the IPMI protocol or sends instructions to the blade nodes to adjust CPU frequency of the blade nodes and memory frequency of the blade nodes for controlling blade power consumption; simultaneously, each fan is independently connected with the system management center SMC through I2C protocols, feeds back rotational speed information to the system management center SMC or receives the instructions from the system management center SMC to adjust the rotational speed of the fan; furthermore, each blade and each fan carry out communication with the system management center SMC through independent addresses to guarantee independence in a control system.

Description

technical field [0001] The invention relates to the technical field of server heat dissipation, in particular to an intelligent heat dissipation control method applied to blade servers. Background technique [0002] With the development of cloud computing technology, people's demand for high-density computing servers is becoming stronger and stronger, and blade servers, as a small-volume, high-density server architecture, are increasingly welcomed by builders of large computer rooms and become a server application However, the high density brings about an increasing demand for system cooling capacity, so the requirements for fan speed and wind pressure will also continue to increase. This phenomenon will bring two negative problems. [0003] First, the increase of fan speed and wind pressure will inevitably increase the power consumption of the fan, and the blade server used as a high-density computing cluster has relatively large requirements for electric power, and the inc...

Problems solved by technology

[0002] With the development of cloud computing technology, people's demand for high-density computing servers is becoming stronger and stronger, and blade servers, as a small-volume, high-density server architecture, are increasingly welcomed by builders of large computer rooms and become a server application However, the high density brings about an increasing demand for system cooling capacity, so that the requirements for fan speed and wind pressure will also continue to increase. This phenomenon will bring two negative problems

[0003] First, the increase of fan speed and wind pressure will inevitably increase the power consumption of the fan, and the blade server used as a high-density computing cluster has relatively large requirements for electric power, and the increase of fan power consumption will make the blade system Part of the application or performance has to be sacrificed to ensure the overall power supply of the blade system

[0004] Second, due to the increase in design technical difficulty brought about by the high speed and high wind pressure of the fan, the failure rate of the fan tends to increase, and once a fan of the system fails, all system blades must enter the protection state , may cause the entire server to stop directly or run inefficiently
