Abstract
The invention discloses an energy-saving and noise-reduction server fan regulation and control method, which belongs to the computer technology field. The energy-saving and noise-reduction server fan regulation and control method comprises the following steps: firstly, FW reads CPU Thermal Margin, the parameter of TDP (Thermal Design Power) is used for calculating the temperature point of the CPU of the model; secondly, the FW reads the current temperature of the CPU and reads the current PWM (Pulse Width Modulation) of a fan; and finally, according to the temperature point, the current temperature of the CPU and the current PWM of the fan, new PWM of the fan is calculated, and the revolving speed of the fan is regulated by taking the new PWM of the fan as a criterion until the temperature of the CPU is controlled to be near the temperature point. Compared with the prior art, the energy-saving and noise-reduction server fan regulation and control method can lower the revolving speed of the fan on the premise that system performance is not affected and the cooling requirement of a system is met, so that the power consumption of the fan is lowered, and fan noise is lowered so as to achieve purposes on saving energy and reducing noise for a server.
Description
Technical field
The present invention relates to field of computer technology, specifically a kind of server fan regulate and control method of energy-saving and noise-reducing.
Background technology
FW is server monitoring administrative unit; FAN is fan module.
PWM is the abbreviation of Pulse Width Modulation, and Chinese " pulse-length modulation " by name, is to utilize the numeral of microprocessor to export the very effective technology of the one that mimic channel is controlled.What this patent was expressed is the dutycycle of fan.
PECI is platform environment formula control interface, and PECI is the english abbreviation of Platform Environment Control Interface.
Along with computer technology, the development of Internet technology, requires to get more and more to number of servers, server room construction is had higher requirement, and to the control index of machine room noise, and more harsh to the control index of machine room electricity consumption.How can reduce energy consumption of machine room and noise just becomes urgent problem.
Summary of the invention
Technical assignment of the present invention is to provide a kind of server fan regulate and control method of energy-saving and noise-reducing.
Technical assignment of the present invention is realized in the following manner, and FW is connected with TACH signal by pwm signal with at least one FAN, and FW and CPU are interconnected by PECI bus;
Method of operating is as follows:
First, FW reads CPU Thermal Margin, and the parameter of TDP is for calculating the temperature spot of this model CPU; Secondly, FW reads CPU Current Temperatures, reads the current PWM of fan; Finally, according to temperature spot, CPU Current Temperatures, the current PWM of fan calculates the fan PWM making new advances, and taking this new fan PWM as benchmark, regulates rotation speed of the fan, until cpu temperature is controlled near temperature spot.
Described pwm signal is the signal of controlling rotation speed of the fan, and TACH signal is the fan rotating speed signals that reads acquisition.
When CPU Current Temperatures is during lower than temperature spot, PWM reduces gradually, and rotation speed of the fan reduces gradually, and cpu temperature is during higher than temperature spot, and PWM increases gradually, and rotation speed of the fan increases gradually, until cpu temperature is controlled near temperature spot to server system steady operation.
