Embodiment 1

[0038] Embodiment 1 of the present invention proposes a system and method for automatically adjusting the CPU voltage alarm threshold, which is used to solve the problem that the CPU voltage alarm threshold is fixed in the prior art, and the influence of the CPU model and Load Line value is not considered, resulting in false alarms of the BMC voltage alarm. question. It also solves the problem that the VR Load Line value of the CPU power supply cannot be automatically adjusted according to the CPU model in the prior art solution, the setting of the voltage alarm threshold is not accurate enough, and the problem that the alarm cannot be issued in time when the actual voltage is abnormal.

[0039] Such as figure 2 A schematic connection diagram of a system for automatic adjustment of the CPU voltage alarm threshold in Embodiment 1 of the present invention is given. The system includes a baseboard management controller BMC, a platform control center PCH, a central processing uni...

Embodiment 2

[0061] Based on Embodiment 1 of the present invention, a system for automatically adjusting the CPU voltage alarm threshold is proposed, and Embodiment 2 of the present invention also proposes a method for automatically adjusting the CPU voltage alarm threshold. Such as image 3 It is a flowchart of a method for automatically adjusting the CPU voltage alarm threshold in Embodiment 2 of the present invention.

[0062] In step S201: the platform control center communicates with the central processing unit, acquires the model information of the central processing unit, and feeds the model information back to the baseboard management controller;

[0063] In step S202: the baseboard management controller invokes the pre-stored information of all CPUs according to the model information, reads the actual output voltage value of the power supply module through the PMBUS, and monitors whether the actual voltage value exceeds the voltage alarm threshold.

[0064] The method also includ...

Abstract

The invention provides a system and method for automatically adjusting a CPU voltage alarm threshold value. The system comprises a BMC, a PCH, a CPU and a VR. The BMC is in communication connection with the PCH; the PCH is in communication connection with the CPU; the CPU is in communication connection with the voltage output end of the VR; the BMC device is also in communication connection with the enabling end of the VR; the VR receives a voltage regulation instruction sent by the BMC to supply power to the CPU; the PCH identifies the model of the CPU through the inherent code of the CPU and feeds back the model information to the BMC; and after receiving the model information, the BMC calls all pre-stored CPU information according to the model information, and then automatically adjusts a CPU voltage alarm threshold. Based on the system, the invention further provides a method for automatically adjusting the CPU voltage alarm threshold value. According to the invention, the problem that BMC voltage monitoring data is not accurate enough or misinformation is avoided, and the accuracy of fault diagnosis and the reliability of server operation are improved.

Description

technical field [0001] The invention belongs to the technical field of server voltage monitoring, and in particular relates to a system and method for automatically adjusting a CPU voltage alarm threshold. Background technique [0002] BMC voltage alarm is an important part of the server system fault diagnosis system. When the server is running, the BMC will sample the output voltage of each VR on the motherboard in real time, and compare and judge with the voltage alarm threshold stored in the BMC. If the sampled voltage value exceeds the threshold setting, the BMC will judge the voltage state as If there is an exception, an alarm message is sent to the system and recorded in the BMC log. Among all the BMC voltage alarms, the CPU voltage is the most important one. How to ensure that the BMC can accurately determine whether the CPU voltage status is normal is very important. The actual voltage value of the CPU will be affected by the Load Line (load line) value and the max...
