Monitoring device and monitoring method for equipment fan

Abstract

The invention discloses a monitoring device for an equipment fan. The monitoring device comprises a fan rotating speed detection device, a signal detection circuit and an alarm module, wherein the fanrotating speed detection device is arranged on a fan module of equipment, a first receiving end of the signal detection circuit is connected with the fan rotating speed detection device, a second receiving end of the signal detection circuit is connected with a fan in-place signal end of the fan module, and an output end of the signal detection circuit is connected with the alarm module; when thesignal detection circuit detects that the rotating speed of the fan module is zero and determines that the fan module is not in place, the alarm module is controlled to give a fan fault alarm. Therefore, the situation of fan fault false alarm caused by abnormal change of the fan rotating speed threshold in the BMC chip is avoided, fan fault false alarm events are reduced, interference to operation and maintenance of a data center is reduced, and the situation that the failure rate of the whole server is higher than an actual value is reduced. The invention further discloses a monitoring method of the equipment fan, and the monitoring method has the above beneficial effects.

Description

technical field [0001] The invention relates to the technical field of server monitoring, in particular to a monitoring device and a monitoring method for equipment fans. Background technique [0002] In a server system, a BMC (Baseboard Management Controller, baseboard management controller) is usually used to monitor and manage the health status of the mainboard. Some important parameters on the motherboard, such as voltage, temperature, and power consumption, are monitored and recorded through the BMC. The monitoring and regulation of the fan speed is also realized through the fan control module inside the BMC. The monitoring and control link of the fan speed of the server is mainly composed of the following links: First, the BMC collects the temperature register information of the key parts of the motherboard and key components through the I2C bus, and then converts the register value inside the BMC to form the temperature register information that we can identify. The ...

[0003] However, during the actual use of the server, the fan speed threshold may suddenly change abnormally, causing the originally normal fan speed to be identified as an abnormal speed. After the BMC chip 102 determines that the speed is abnormal, the fan failure indicator will light up. 103, leading to false alarms, which greatly interferes with the operation and maintenance of the data center, and also has a bad impact on the failure rate of the server as a whole
