Description

Technical Field

[0001] The present application relates to the field of heat dissipation processing technology, and in particular to a fan speed regulation method, device, computer equipment and storage medium. Background Art

[0002] The current fan speed adjustment method for heat-generating devices cannot accurately determine the status of the heat-generating device by relying solely on the baseboard management controller. When the heat-generating device fails, if the temperature sent by the heat-generating device to the baseboard management controller is always a fixed value, the baseboard management controller believes that the heat-generating device is in a normal state and will always adjust the speed according to this temperature. The fan speed cannot be guaranteed and the heat dissipation demand cannot be met. When the temperature of the heat-generating device changes from having a reading to not having a reading, abnormal speed adjustment is performed. If the status of the heat-generating device changes from being in place to not being in place, the baseboard management controller believes that the heat-generating device does not exist and will not enter abnormal speed adjustment. The fan speed cannot be guaranteed and the heat dissipation demand cannot be met. If the heat dissipation control is performed according to the model, and the control data value is fixed, the heat dissipation demand of the heat-generating device when the status is abnormal cannot be met.

[0056] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0057] At present, with the rapid development of AI technology, ChatGPT, Metaverse, and big data processing, the demand for AI servers is increasing. How to ensure the efficient and safe operation of AI servers has become particularly important. The heat dissipation design of the key components of heat-generating devices in AI servers is more prominent. How to ensure the heat dissipation of heat-generating devices is the key to extending the service life of heat-generating devices.

[0058] The fan speed control method provided in this application can be applied to Figure 1In the application environment shown in the figure. In the server, there is a heat generating device, and the heat generating device is provided with a fan for cooling. The heat generating device includes a graphics processing unit (GPU), a programmable logic device (FPGA), a network card, and a physical processing unit (PPU). In modern server architecture, in order to enhance the reliability of monitoring of heat generating devices, a collaborative working mode of a basic input and output system (BIOS) and a baseboard management controller (BMC) is adopted. The heat generating device is connected to both the basic input and output system (BIOS) and the baseboard management controller (BMC). In the example, when the heat generating device is a graphics processing unit (GPU), the baseboard management controller determines whether the graphics processing unit has been correctly installed and is in an active state by parsing the SMBIOS (System Management BIOS) information provided by the BIOS, which serves as a preliminary means of confirming the in-place state of the graphics processing unit. In addition, the baseboard management controller also uses the I2 C (Inter-Integrated Circuit) bus to directly communicate with the graphics processing unit to independently verify its physical existence. These two methods are redundant with each other. As long as any one of them indicates that the graphics processor is in place, it can be determined that the graphics processor is operating normally, thereby ensuring that even if the graphics processor itself fails, it will not affect the abnormal speed regulation strategy of the server fan and maintain the cooling efficiency of the system.

[0059] In one embodiment, Figure 2 As shown, a fan speed control method is provided, which is applied to Figure 1 The baseboard management controller in the example is used to illustrate, including the following steps:

[0060] Collecting working data of the heat generating device, analyzing the working data to determine whether the real-time temperature of the heat generating device can be read normally;

[0061] In response to the real-time temperature of the heat generating device being read normally, the fan of the heat generating device is controlled to enter a normal speed adjustment mode; in response to the real-time temperature reading of the heat generating device being abnormal, whether the heat generating device is in place is determined through an integrated circuit bus;

[0062] In response to determining that the heat generating device is in place through the integrated circuit bus, controlling the fan of the heat generating device to enter an abnormal speed adjustment mode; in response to determining that the heat generating device is not in place through the integrated circuit bus, determining whether the heat generating device is in place through a basic input and output system;

[0063] In response to the basic input and output system determining that the heat generating device is in place, the fan of the heat generating device is controlled to enter an abnormal speed regulation mode; in response to the basic input and output system determining that the heat generating device is not in place, the fan of the heat generating device is controlled to enter a normal speed regulation mode.

[0064] Among them, taking the heat-generating device as a graphics processor (GPU) as an example, the baseboard management controller determines the status of the graphics processor through the system basic input and output information (System Management BIOS, SMBIOS) sent by the BIOS as a redundant way for the baseboard management controller to determine the status of the graphics processor through the I2C integrated circuit bus. Any one of them in place represents that the graphics processor is in place, ensuring that the status of the graphics processor in place is not affected by the failure of the graphics processor, so that the baseboard management controller can make the server fan enter abnormal speed regulation. Confirming the status of the graphics processor in place through the system basic input and output information of the BIOS can achieve further accurate judgment when the baseboard management controller cannot know the status of the graphics processor in place, ensuring that the status of the graphics processor in place can be accurately detected.

[0065] like Figure 2 As shown, in this embodiment, the collecting of the working data of the heat generating device and parsing the working data to determine whether the real-time temperature of the heat generating device can be read normally include:

[0066] In response to the server being started, collecting system basic input and output information through a basic input and output system;

[0067] The baseboard management controller determines whether the heat generating device has been correctly installed and / or the activity status of the heat generating device by parsing the basic input and output information of the system;

[0068] In response to the heat generating device being correctly installed and / or the activity state of the heat generating device being normal, the working data of the heat generating device in the basic input and output information of the system is parsed, and whether the real-time temperature of the heat generating device can be read normally is determined by whether the real-time temperature of the heat generating device exists in the working data.

[0069] Specifically, when the server starts, the BIOS collects information related to the server's hardware peripherals, and information about heat-generating devices such as the graphics processor is also collected. The BIOS sends an IPMI command to the baseboard management controller through the KCS channel, and sends the system basic input and output information collected by the BIOS to the baseboard management controller. The baseboard management controller determines whether the graphics processor is in place or not through the system basic input and output information. When the graphics processor fails, if the temperature of the graphics processor changes from being readable to being unreadable, the baseboard management controller first determines whether the graphics processor is in place through the I2C channel. If it is in place, the fan is put into abnormal speed regulation mode. If the baseboard management controller cannot obtain the graphics processor in place status through the I2C channel, the baseboard management controller continues to determine whether the graphics processor is in place through the system basic input and output information. If it is in place, the fan is put into abnormal speed regulation mode.

[0070] like Figure 3 As shown, in this embodiment, the fan speed regulation method further includes:

[0071] In response to the server being started, polling the bandwidth of the heat generating device through the basic input and output system;

[0072] The basic input and output system monitors the bandwidth of the heat generating device to determine whether the bandwidth of the heat generating device changes;

[0073] In response to the broadband of the heat generating device not changing, controlling the fan of the heat generating device to enter a normal speed regulation mode;

[0074] In response to abnormal fluctuations in the bandwidth of the heat generating device, the basic input and output system sends an alarm message to a baseboard management controller, so that the baseboard management controller tracks the bandwidth changes of the heat generating device in real time;

[0075] In response to the baseboard management controller detecting that the bandwidth of the heat generating device changes, the real-time temperature of the heat generating device within a preset time period is collected, and it is determined whether the real-time temperature of the heat generating device within the preset time period is the same value;

[0076] In response to the real-time temperature of the heat generating device being the same value within a preset time period, controlling the fan of the heat generating device to enter an abnormal speed regulation mode;

[0077] In response to the real-time temperature of the heat generating device not being the same value within a preset time period, the fan of the heat generating device is controlled to enter a normal speed regulation mode.

[0078] Taking the heat-generating device as a graphics processor (GPU) as an example, in order to further improve the performance monitoring level of the server, the BIOS integrates a continuous graphics processor bandwidth monitoring function. Once an abnormal fluctuation in the graphics processor bandwidth is detected, the BIOS will immediately send an alarm message to the baseboard management controller through the KCS (Keyboard Controller Style) channel, allowing the baseboard management controller to track the bandwidth changes of the graphics processor in real time. This instant feedback mechanism helps the baseboard management controller quickly identify potential graphics processor performance issues.

[0079] Furthermore, the preset duration is preferably 3 minutes. When the baseboard management controller observes a change in the GPU state, especially if the GPU temperature remains unchanged for 3 consecutive minutes, this may indicate that the GPU has encountered some kind of failure or limitation. At this time, the baseboard management controller will automatically start the abnormal control program and adjust the system strategy to cope with potential thermal management or performance challenges. These advanced monitoring and management strategies together build a robust and flexible GPU health monitoring system to ensure that the server can maintain optimal performance and stability under complex workloads and environmental conditions.

[0080] A continuous polling GPU bandwidth detection mechanism is added to the BIOS. When an abnormal change occurs in the GPU bandwidth, the BIOS sends relevant information to the baseboard management controller through the KCS channel, so that the baseboard management controller can monitor the GPU bandwidth change in a timely manner. When the GPU status changes and the GPU temperature obtained by the baseboard management controller is the same value within 3 minutes, the baseboard management controller enters the abnormal control mode.

[0081] Once the GPU status is confirmed to be abnormal, the BMC will immediately start the abnormal speed regulation process, dynamically adjust the server fan speed, enhance the heat dissipation efficiency, and effectively prevent the risk of overheating caused by GPU failure, thereby avoiding possible system performance degradation or hardware damage.

[0082] In this embodiment, controlling the fan of the heat generating device to enter the abnormal speed regulation mode includes:

[0083] The fan speed of the heat generating device is adjusted according to the bandwidth state of the heat generating device and the real-time temperature of the heat generating device.

[0084] Specifically, the fan speed adjustment of the heat generating device according to the bandwidth state of the heat generating device and the real-time temperature of the heat generating device includes:

[0085] In response to the bandwidth state of the heat generating device being normal, determining whether the real-time temperature of the heat generating device is within a normal operating temperature range, if so, maintaining the fan speed of the heat generating device unchanged, if not, obtaining a target speed value corresponding to the fan according to the real-time temperature of the heat generating device, and controlling the fan speed of the heat generating device to be equal to the target speed value;

[0086] In response to the bandwidth state of the heat generating device being abnormal, a target speed value corresponding to the fan is acquired according to the real-time temperature of the heat generating device, and the fan speed of the heat generating device is controlled to be equal to the target speed value.

[0087] This embodiment ensures that the server can enter the abnormal fan speed regulation mode 100%, increase the fan speed, and ensure the heat dissipation effect. In the abnormal speed regulation mode, the fan speed of the heat generating device is reasonably controlled according to whether the bandwidth state of the heat generating device is normal and the real-time temperature of the heat generating device is reasonably combined to ensure the heat dissipation of the heat generating device, thereby extending the service life of the heat generating device.

[0088] like Figure 4 As shown, in this embodiment, controlling the fan of the heat generating device to enter the normal speed regulation mode includes:

[0089] S11, obtaining the name of the heat generating device, and obtaining the fan speed range of the heat generating device according to the name of the heat generating device;

[0090] S12, obtaining a correlation between a fan speed value of the heat generating device and a temperature value of the heat generating device, and obtaining a target speed value corresponding to the fan according to the real-time temperature of the heat generating device;

[0091] S13, controlling the fan speed of the heat generating device to be equal to the target speed value within the fan speed range of the heat generating device.

[0092] When the fan of the heat generating device enters the normal speed regulation mode, the fan speed range of the heat generating device can be obtained based on the name of the heat generating device, and the fan speed of the heat generating device can be reasonably controlled within the fan speed range of the heat generating device.

[0093] In this embodiment, obtaining the name of the heat generating device and obtaining the fan speed range of the heat generating device according to the name of the heat generating device includes:

[0094] Obtaining a name of the heat generating device, where the name of the heat generating device includes one of a graphics processing unit (GPU), a field programmable logic device (FPGA), a network card, and a physical processing unit (PPU);

[0095] According to the name of the heat generating device, a heat dissipation configuration file corresponding to the heat generating device is determined, and according to the heat dissipation configuration file, a fan speed range of the heat generating device is acquired.

[0096] It is understandable that the heat generating device is not only applicable to the graphics processing unit (GPU), but can also be regulated in a similar manner for other server components such as FPGA, network card, PPU, etc. When an abnormality occurs in the heat generating device, it is ensured that the server can enter abnormal speed regulation to extend the service life of the heat generating device.

[0097] In this embodiment, the fan speed adjustment method further includes:

[0098] Obtaining a correlation between a fan speed value and a fan air volume value of the heat generating device, and obtaining an actual fan speed value through an actual fan air volume value corresponding to the heat generating device according to the correlation between the fan speed value and the fan air volume value of the heat generating device;

[0099] According to the correlation between the fan speed value of the heat generating device and the temperature value of the heat generating device, the fan theoretical speed value is obtained through the current temperature value of the heat generating device;

[0100] When the fan theoretical speed value is less than the fan actual speed value, a difference between the fan actual speed value and the fan theoretical speed value is obtained as a speed correction value to correct the fan theoretical speed value.

[0101] By comparing the difference between the fan theoretical speed value of the heat generating device and the fan actual speed value, the fan theoretical speed value can be corrected to achieve more accurate temperature regulation of the heat generating device.

[0102] In the above-mentioned fan speed regulation method, when the real-time temperature reading of the heat generating device is abnormal, firstly, whether the heat generating device is in place is determined through the integrated circuit bus, and secondly, when the integrated circuit bus determines that the heat generating device is not in place, whether the heat generating device is in place is determined through the basic input and output system. Any one of them being in place represents that the heat generating device is in place, which ensures that the in-place state of the heat generating device is not affected by the failure of the heat generating device, so that the baseboard management controller can accurately know the in-place state of the heat generating device, and let the fan of the heat generating device enter the abnormal speed regulation mode, which solves the disadvantage of the traditional fan speed regulation that the abnormal speed regulation only relies on the temperature sensor for regulation, ensures the heat dissipation of the heat generating device, and extends the service life of the heat generating device.

[0103] In one embodiment, Figure 5 As shown, a fan speed regulating device 10 is provided, comprising: a heat generating device temperature monitoring module 1, a temperature-based regulating module 2, a first in-situ regulating module 3, and a second in-situ regulating module 4.

[0104] The heat generating device temperature monitoring module 1 is used to collect the working data of the heat generating device, and analyze the working data to determine whether the real-time temperature of the heat generating device can be read normally.

[0105] The temperature control module 2 is used to control the fan of the heat generating device to enter a normal speed regulation mode in response to the real-time temperature of the heat generating device being read normally, and to determine whether the heat generating device is in place through an integrated circuit bus in response to an abnormal real-time temperature reading of the heat generating device.

[0106] The first in-place control module 3 is used to control the fan of the heat generating device to enter an abnormal speed regulation mode in response to determining that the heat generating device is in place through the integrated circuit bus, and to determine whether the heat generating device is in place through a basic input and output system in response to determining that the heat generating device is not in place through the integrated circuit bus.

[0107] The second in-place control module 4 is used for controlling the fan of the heat generating device to enter an abnormal speed regulation mode in response to determining that the heat generating device is in place through the basic input and output system, and for controlling the fan of the heat generating device to enter a normal speed regulation mode in response to determining that the heat generating device is not in place through the basic input and output system.

[0108] In this embodiment, the collecting of the working data of the heat generating device and analyzing the working data to determine whether the real-time temperature of the heat generating device can be read normally include:

[0109] In response to the server being started, collecting system basic input and output information through a basic input and output system;

[0110] The baseboard management controller determines whether the heat generating device has been correctly installed and / or the activity status of the heat generating device by parsing the basic input and output information of the system;

[0111] In response to the heat generating device being correctly installed and / or the activity state of the heat generating device being normal, the working data of the heat generating device in the basic input and output information of the system is parsed, and whether the real-time temperature of the heat generating device can be read normally is determined by whether the real-time temperature of the heat generating device exists in the working data.

[0112] In this embodiment, the Figure 5 As shown, a fan speed regulating device 10 is provided, which also includes: a broadband monitoring module 5 and a temperature constant control module 6.

[0113] In response to the server startup, the broadband monitoring module 5 polls the broadband of the heat generating device through the basic input and output system; the basic input and output system monitors the broadband of the heat generating device to determine whether the broadband of the heat generating device changes; in response to the broadband of the heat generating device not changing, the fan of the heat generating device is controlled to enter the normal speed regulation mode; in response to the broadband of the heat generating device showing abnormal fluctuations, the basic input and output system sends an alarm message to the baseboard management controller, so that the baseboard management controller tracks the bandwidth changes of the heat generating device in real time.

[0114] In response to the baseboard management controller detecting that the bandwidth of the heat generating device has changed, the temperature constant control module 6 collects the real-time temperature of the heat generating device within a preset time period, and determines whether the real-time temperature of the heat generating device is the same value within the preset time period; in response to the real-time temperature of the heat generating device being the same value within the preset time period, the fan of the heat generating device is controlled to enter an abnormal speed regulation mode; in response to the real-time temperature of the heat generating device not being the same value within the preset time period, the fan of the heat generating device is controlled to enter a normal speed regulation mode.
