[0011] Glossary:

[0012] IPMI: Intelligent Platform Management Interface (Intelligent Platform Management Interface) is an open standard hardware management interface specification that defines a specific method for embedded management subsystems to communicate. IPMI information is communicated through the Baseboard Management Controller (BMC), which is located on the IPMI-compliant hardware component. Using low-level hardware intelligent management instead of operating system management, users can utilize IPMI to monitor the physical health characteristics of the server, such as temperature, voltage, fan working status, power supply status, etc. And more importantly, IPMI is an open and free standard, and users do not need to pay extra fees for using this standard. There are two main advantages: first, this configuration allows for out-of-band server management, and second, the operating system is not burdened with transferring system state data.

Abstract

The invention relates to the field of servers, and particularly to an operating system based CPU temperature obtaining method. The method comprises the following steps of: A) a BMC determining whether a CPU temperature obtained from the ME is correct; B) if the CPU temperature obtained from the ME is correct, applying the temperature to a heat dissipation system; C) if the CPU temperature obtained from the ME is not correct, the BMC obtaining the CPU temperature by using the BIOS; and D) applying the CPU temperature obtained in step C to the heat dissipation system. According to the method, for the problem in the existing scheme according to which the BMC obtains the temperature, improvement and optimization are performed: a candidate scheme is added, so that two schemes can be selected to obtain the CPU temperature, the correctness of the temperature can be determined and checked, and it is ensured that the temperature provided to the heat dissipation system is correct, thereby enabling the heat dissipation system to work normally, improving reliability of the heat dissipation system, and meanwhile avoiding fan noise pollution and wasting of power caused by an invalid temperature.

Description

technical field [0001] The invention relates to the field of servers, in particular to a method for obtaining CPU temperature under an operating system. Background technique [0002] In the field of servers, as servers become more integrated and more popular, manufacturers and users pay more and more attention to cooling systems. Different heat dissipation systems, obtaining accurate CPU temperature is one of the necessary conditions for heat dissipation. At present, the fan cooling system controlled by BMC obtains the CPU temperature through ME. First, ME reads the CPU temperature in PECI mode, then BMC communicates with ME, sends a series of command requests and ME responses, and finally obtains the temperature value, such as figure 1 shown. [0003] Most of the existing methods for BMC to obtain temperature are no problem, but there is a small probability that there will be problems. When BMC and ME communicate, if BMC does not receive a response from ME on time after ...
