Abstract

The invention provides a centralized control management method for a large server radiator fan, which aims to achieve the effects of optimal system radiation and energy saving in a way that a monitoring management module monitors temperatures of each node and an exchange module of a system in real time, performs grouping management on fans in a fan disk and senses and controls rotating speeds of the fans through an SMBUS. The system architecture comprises a hot plug control module, a fan control module, a delay module, a fan disk front-end switch and fault indication module and the monitoring management module, wherein the hot plug control module is used for protecting a power supply and signals in a hot-plug of the fan disk; the fan control module is used for sensing and controlling the rotating speeds of the fans; the fan disk front-end switch and fault indication module is used for switching the fan disk on / off and giving an alarm for failing fans; and the monitoring management module reads the temperatures of all the modules and monitors and manages all the fans through the system management bus.

Description

technical field [0001] The invention relates to the field of computer communication, in particular to a control method for a fan of a large-scale server system with more than 32 channels. Background technique [0002] Multi-channel server is developed along with the development of computer technology. The original intention of the invention of the computer is to improve computing power and process complex data. However, with the development of technology and the progress of the times, in some fields such as scientific computing and financial systems, higher and higher requirements are placed on the processing capabilities of computers. In the past few decades, it can be said that it is an era of continuous innovation in computer technology, and new system architectures continue to emerge. From the initial single-CPU system to the later multi-CPU system, chip manufacturers are constantly exploring new system architectures. System application vendors are also constantly rese...
