Abstract

The invention provides a fan energy-saving control method, system, terminal and storage medium, including: setting the corresponding relationship between the shutdown duration and the pulse signal difference; setting the BMC to store the current environment variable after receiving the shutdown signal, the environment variable Including the shutdown time and the fan pulse signal during shutdown; collect the previous shutdown time and the current startup time, and calculate the current shutdown duration according to the previous shutdown time and the current startup time; according to the current shutdown duration and the corresponding relationship Query the difference value of the corresponding pulse signal; collect the fan pulse signal during the previous shutdown, and use the difference between the fan pulse signal during the previous shutdown and the difference between the corresponding pulse signal as the fan control pulse signal for the current startup. The invention can control the fan speed during the start-up process of the server, so as to achieve the effect of fan energy saving.

Description

technical field [0001] The present invention relates to the technical field of servers, in particular to a fan energy-saving control method, system, terminal and storage medium. Background technique [0002] In the server field, BMC is mainly implemented by Embedded Linux. The boot process is to start the bootloader program first, then start the Kernel and Application. During this process, the BMC cannot perform complex services, and the events that will trigger the boot process may include: update the BMC firmware , command to trigger reset BMC, AC off / on server. [0003] The time for the BMC to perform the boot process is generally between 3 and 8 minutes. Only after the BMC is powered on can a suitable fan control algorithm intervene. At present, the general design of the server is that before the BMC is started, the fan speed is fixed at 100% duty cycle. In the data center environment, this period of time consumes power. SUMMARY OF THE INVENTION [0004] In view of t...
