Problems solved by technology

In this binary judgment situation, the system cannot monitor the operation status of the fan controller and the fan at the same time, and the customer insists on using this discrete signal to judge whether the fan control is normal. How to provide an effective method for the server to monitor the fan control at the same time? The operating status of the controller and fan becomes very important

Embodiment Construction

[0025] refer to figure 1 Shown is a schematic diagram of the operating environment of a preferred embodiment of the fan error detection system 100 of the present invention. In this embodiment, the fan error detection system 100 is installed and operated in the server 1, the server 1 includes, but not limited to, a BMC controller (Baseboard Management Controller) 10, a memory 12, a central processing unit (CPU ) 13 and display 14. The BMC controller includes a communication pin (Communication Pin) 11 , and connects the server 1 and the fan controller 2 through the communication pin 11 , and the fan controller 2 is electrically connected to the fan wall 3 . The fan wall 3 is equipped with one or more sets of fans 30 for cooling the server 1 by heat dissipation. The memory 12 may be memory, Flash ROM, Hard disk or other disks.

[0026] In this embodiment, when the potential of the communication pin 11 is high for 5 seconds, it is determined that the fan controller 2 is damaged...

Abstract

The invention discloses a fan error detection system and method which are applied to a server. The server comprises a BMC (Baseboard Management Controller), wherein the server and a fan controller are connected through communication pins of the BMC, the fan controller is electrically connected to a fan wall, and one or more groups of fans are mounted on the fan wall. The fan error detection system comprises a potential detection module, an abnormality reporting module, and an abnormality processing module, wherein the potential detection module continuously monitors the pin voltages of the communication pins between the server and the fan controller; the abnormality reporting module detects whether abnormalities of the fans or the fan controller occur or not according to the pin voltages; in case of the abnormalities of the fans or the fan controller, the abnormality processing module reduces the CPU frequency of the server to lower the system temperature of the server. The fan error detection system and method have the advantages that the abnormalities of the fans and the fan controller can be detected at the same time; in case of the abnormalities of the fans or the fan controller, the CPU frequency of the server can be reduced to lower the lower system temperature of the server.

Description

technical field [0001] The present invention relates to a server cooling monitoring system and method, in particular to a server fan error detection system and method. Background technique [0002] In server development projects, the method of cabinet shared fan control is generally adopted, and there are many (39) servers in the entire cabinet sharing a group of fan walls. The composition of the fan wall includes a set of fan controllers and 30 sets of fans. Among them, 3 servers are connected to the fan controller, so as to know whether the fan is operating normally. [0003] Among them, the truth table for judging the operating status of the fan and the fan controller and the meanings contained in it are as follows: the binary value of GPIOO3_TACH3_VPR1 is high (HIGH) indicating that the fan controller is abnormal; the binary value of GPIOO3_TACH3_VPR1 is low (LOW) indicating the fan speed Abnormal, the abnormal situation includes the speed is too slow, the speed is too...
