Intelligent control method suitable for server fan in private cloud system under low-temperature environment

Abstract

The invention provides an intelligent control method suitable for a server fan in a private cloud system under a low-temperature environment and belongs to the field of private cloud servers. According to the intelligent control method provided by the invention, temperature is detected by adding an intelligent temperature control chip below a CPU (central processing unit) and a bridge blade on a server mainboard to judge whether the fan needs to be started or not. An environment temperature point that the chip intends to detect can be configured by the chip through a resistor connected with the exterior of the chip; after the temperature reaches the monitoring point, low level can be output by a corresponding pin of the chip; the fan is powered up to be started by matching an external control circuit; when the environment temperature is lower than the set temperature point, the fan is not powered up. The problem that the starting failure of the server is caused due to the fact that the powered-up fan is uncontrollable under the low-temperature fan is solved; through the intelligent control of the fan in the private cloud system under a special environment, the normal operation of the system at low temperature is guaranteed, and the product stability is improved.

Description

[0001] Technical field [0002] The present invention involves the field of private cloud servers. Specifically, it is suitable for intelligent control methods for server fan fan in the low -temperature environment private cloud system. Background technique [0003] At present, the fan control in the private cloud server system usually uses BIOS or BMC or the management module on the server motherboard for temperature collection control fan speed. Because BIOS and BMC startup takes a certain period of time, the fan during the startup process is in an out of control at the default speed speed at the default speed speed.Rotating, it will not affect the server startup at room temperature, but at low temperature environments, there is no industrial -grade products because the processor and other chips are not industrial -grade, and the local measures need to be warmed at low temperature. At this time, if the fan is runningDisposal the heat generated by the chip may cause the server ...

AI Technical Summary

Problems solved by technology

[0003] At present, the fan control in the private cloud server system usually uses the BIOS or BMC or management module on the server motherboard to collect temperature and control the fan speed, because both BIOS and BMC are required to start For a certain period of time, the fan is in an out-of-control state during the startup process and rotates at the default speed. It will not have any impact on the startup of the server under normal temperature conditions. Measures such as preheating are required to raise the temperature. At this time, if the fan is running, the heat generated by the chip will be dissipated, which may cause the server to start abnormally at low temperature.
