Description
Technical Field
The present invention relates to the field of server heat dissipation, and in particular, to a method and a system for controlling a server fan, an electronic device, and a storage medium.
Background
Currently, the server industry is increasingly competitive, and all mass manufacturers have realized the basic functions of the server; the types of servers available for clients to select are more and more, and the performance requirements of clients on the servers are also higher and higher. Thus, the user experience becomes increasingly important in meeting the conditions of normal use of the server. At present, it is proposed by a client that when a current server is in an inactive (initialization state of the BMC and a dead state in the working process of the BMC) at the BMC (Baseboard Manager Controller, baseboard management controller), the fan rotation speed cannot be effectively regulated and controlled, so that the power consumption of the server is high, meanwhile, the noise problem is serious, and the user experience is very poor.
After the server is powered on, the PCH (Platform Controller Hub, integrated south bridge) informs the BMC of the information of PCIE (Peripheral Component Interconnect Express, high-speed serial computer expansion bus standard) card through the bus; meanwhile, the BMC also obtains the temperature of each temperature measuring point of the server through the temperature sensor, and then sends PWM (pulse width modulation) to control the fan according to the heat dissipation strategy. Because the software system of the BMC is long in initialization process, the problem of dead downtime often occurs, and the fan cannot be controlled to effectively radiate the server. Therefore, the prior art proposes to process PWM using a CPLD (Complex Programmable Logic Device ) when performing fan control; CPLD, judge BMC normal work; if the BMC works normally, the CPLD thoroughly transmits PWM sent by the BMC to control the fan, and when the BMC is inactive, the CPLD controls the fan at a fixed rotating speed given by heat dissipation, so that abnormal work caused by overhigh temperature of the server is avoided. However, since the CPLD only performs fan control at a fixed rotational speed; in order to meet the heat dissipation requirement of the highest configuration of the server, the fan rotation speed setting must be very high (such as 80% -100%); however, most server shipment configurations do not use the highest configuration, and in this case, the high rotation speed of the fan brings high power consumption and high noise, and gives the client agent a poor experience.
Therefore, a method for controlling a fan of a server is needed to reasonably set the rotational speed of the fan during BMC inactive, and improve the user experience.

Example 1
As shown in fig. 1, an embodiment of the present application provides a server fan regulation architecture: after the server is electrified, PCH is connected with BMC through a bus; the BMC is connected with a temperature Sensor (Sensor) and a programmable logic device (CPLD) through an I2C bus, the CPLD also receives PWM sent by the BMC and transmits the PWM to the fan, and the BMC receives a feedback signal returned by the fan. Specifically, by using the server fan regulation and control architecture provided by the embodiment of the present application, a process for regulating and controlling a rotation speed of a server fan includes:
s1, the BMC acquires server configuration information and sensor temperature information.
Specifically, when the PCIE device performs hot plug, the PCH informs the BMC of the information of the PCIE card through the ESPI/LPC bus, and the BMC reads the PCIE device information accessed out-of-band by the server and updates the configuration information of the server; and re-reading and updating the server configuration information every time the server is powered on by direct current. Meanwhile, the BMC can acquire the temperature of the temperature measuring points of the server through the temperature sensor and update the temperature information of the sensor. The server configuration information includes types and kinds of a CPU, a memory, a hard disk, a board card, and the like.
S2, the BMC acquires server configuration information and sensor temperature information to determine fan control information, and writes the fan control information into the programmable logic device.
Because the heat dissipation capacity required by the server is different under different server configurations, the application takes the server configuration and the sensor temperature as influencing factors to formulate a server heat dissipation strategy, and the heat dissipation strategy comprises fan control information corresponding to different server configurations and different sensor temperatures. After identifying the server configuration information, the BMC converts the heat dissipation policy of the heat dissipation server under the configuration into fan control information in combination with the sensor temperature, for example: the rotating speed of the fan is 10% within 1 min; 1-2 min, the rotating speed of the fan is 15%; 2-3 min, the rotating speed of the fan is 30; 3-4 min, the rotating speed of the fan is 45%; the rotating speed of the fan is 50% after more than 4 min; the BMC was dead and the fan speed was 60%. It can be understood that the fan control information provided by the application can be regarded as the corresponding relation between the time node after the server is powered on and the fan rotating speed and the corresponding fan rotating speed when the server is dead, and the change of the fan rotating speed along with the time shows a stepwise increasing trend.
The BMC transmits the fan control information to the programmable logic device through the I2C, and updates the fan control information in real time according to the server configuration. The programmable logic device is provided with a nonvolatile Memory area, which may be preferably a UFM (UsrFlash Memory) or any other Memory module applicable to the programmable logic device.
S3, judging the working state of the BMC.
Specifically, after the server is powered on, the working state of the BMC is judged. Judging whether the BMC works normally or not according to whether the programmable logic device can receive a watchdog signal sent by the BMC or not in a first preset period after the server is electrified by the alternating current power supply; if the programmable logic device receives a watchdog signal sent by the BMC in a first preset period, judging that the BMC can work normally; if the programmable logic device does not receive the watchdog signal sent by the BMC in the first preset period, the BMC is judged to not work normally and is still in an initialized state. Then, continuously monitoring whether the programmable logic device can receive the watchdog signal sent by the BMC, and if the programmable logic device does not receive the watchdog signal sent by the BMC in a second preset period after the server alternating current power supply is electrified, determining that the BMC is in a dead state at the moment; if the programmable logic device receives a watchdog signal sent by the BMC in a second preset period after the server alternating current power supply is electrified, the BMC is determined to be initialized, and the programmable logic device starts to enter a normal working state.
S4, determining the rotating speed of the fan according to the working state of the BMC so as to complete regulation and control of the server fan.
If the BMC is in a normal working state, the programmable logic device directly regulates and controls the server fan according to PWM issued by the BMC in real time. If the BMC is in an initialized state, the control right of the BMC is released, the programmable logic device reads fan control information stored in the nonvolatile storage area, a power-on time node after the server is powered on in an alternating mode is determined through an internal timer arranged in the programmable logic device, and a proper fan rotating speed is obtained according to the corresponding relation between the power-on time node and the fan rotating speed; the programmable logic device generates corresponding PWM according to the fan rotating speed, and the rotating speed of the server fan is controlled through the PWM; if the BMC is in an initialized state, the control right of the BMC is also released, the programmable logic device reads the fan control information stored in the nonvolatile storage area, inquires the fan rotating speed corresponding to the dead state of the BMC, generates corresponding PWM, and controls the rotating speed of the fan of the server through the PWM.
