Description

Technical Field

[0001] The present disclosure relates to the field of server technology, and in particular to a fan testing method, device, equipment and storage medium. Background Art

[0002] As the computing power of servers increases, their power consumption also increases. As power consumption increases, how to effectively dissipate heat from servers has become an urgent problem to be solved.

[0003] Some current technologies install fans in servers and use the fans to dissipate heat for the servers. However, as the power consumption of the server increases, the speed of the fans also increases. At high speeds for a long time, the fans are prone to failure, which in turn causes the server cooling system to be abnormal. In the case of an abnormality in the cooling system of the server, the heat generated during the operation of the server will increase the temperature of its hardware, which in turn causes hardware damage or system crashes. It can be seen that the reliability of the fans is closely related to the cooling reliability of the server.

[0004] At present, some technologies can only detect fans that have already had problems. Based on this detection method, when a fan failure is detected, the heat generated by the server may have caused hardware damage and other problems. Therefore, the heat dissipation reliability of the server needs to be improved. Summary of the invention

[0005] In view of this, the present disclosure provides a fan testing method, a fan testing device, an electronic device, and a computer-readable storage medium, which can improve the heat dissipation reliability of a server.

[0008] According to a preset speed change logic, the speed of the fan is controlled to cyclically change between the minimum test speed and the maximum test speed for a target time, and actual operation data of the fan is collected;

[0009] Acquiring theoretical operation data of the fan that matches the speed change logic;

[0010] A test result of the fan is determined according to a difference between the actual operation data and the theoretical operation data, and the test result is used to characterize whether the fan has a potential fault.

[0011] In a second aspect, the present disclosure provides a fan testing device, the device comprising:

[0012] A rotation speed acquisition module, used to acquire the minimum test rotation speed and the maximum test rotation speed of the fan;

[0013] A speed control module, used to control the speed of the fan to cyclically change between the minimum test speed and the maximum test speed for a target duration according to a preset speed change logic, and to collect actual operation data of the fan;

[0014] A calculation module, used for obtaining theoretical operation data of the fan that matches the speed change logic;

[0015] The test result generating module is used to determine the test result of the fan according to the difference between the actual operation data and the theoretical operation data, and the test result is used to characterize whether the fan has a potential fault.

[0016] In a third aspect, the present disclosure provides an electronic device, comprising: a memory and a processor, wherein the memory and the processor are communicatively connected to each other, computer instructions are stored in the memory, and the processor executes the above method by executing the computer instructions.

[0017] In a fourth aspect, the present disclosure provides a computer-readable storage medium having computer instructions stored thereon, the computer instructions being used to enable a computer to execute the above method.

[0018] In the technical solutions of some embodiments of the present disclosure, when the speed of the fan is controlled to cycle between the lowest test speed and the highest test speed for a target time according to the speed change logic, the speed of the fan is in a dynamic change process, so that the fan needs to continuously respond to the speed adjustment to rotate at different speeds, which is equivalent to applying a certain performance pressure to the fan. In this way, when there is a potential fault problem in the fan, based on such a performance stress test, the actual operating data of the fan may show abnormal phenomena, and then, based on these abnormal phenomena, the fan with potential fault problems can be determined. In this way, fans with potential fault problems can be replaced or configured in advance to avoid server heat dissipation problems caused by fan failures, thereby improving the heat dissipation reliability of the server.

[0037] It is understandable that the above notification and the process of obtaining user authorization are merely illustrative and do not constitute a limitation on the implementation of the present disclosure.

[0038] The reliability of the fan in the server is closely related to the heat dissipation reliability of the server. At present, in some technologies, it is impossible to detect the potential failure of the fan in advance when the fan is still in normal operation, and thus it is impossible to repair or replace the fan that may fail in advance. This results in that when the fan failure is detected, the server may have already experienced problems such as downtime due to heat dissipation failure, which greatly reduces the heat dissipation reliability of the server.

[0039] To solve the above problems, we analyzed the fan's operating data and found that before the fan actually fails, its operating data will also show some abnormal phenomena, such as abnormal current changes, abnormal fan speed changes, etc. The higher the frequency of abnormal phenomena in the fan's operating data, the higher the potential risk of failure.

[0040] Based on this, the present disclosure provides a fan testing method, which can improve the heat dissipation reliability of a server. The fan testing method can be applied to a test device. The test device can be a baseboard management controller (BMC) in a server, or can be other devices independent of the server (i.e., the test device can be not one of the components in the server).

[0041] Combined with reference Figure 1 A complex programmable logic device (CPLD) and a monitoring module may be installed in the fan. The test equipment may communicate with the CPLD and the monitoring module. The test equipment may send control commands to the fan through the CPLD. For example, the test equipment may send the following command 1) to the CPLD to turn off the fan's automatic speed control function based on temperature:

[0042] 1)ipmitool.exe-I lanplus-H ip-U username-P password raw 0x30 0x300x010x00

[0043] For another example, the test equipment sends the following command 2) to the complex programmable logic device to set the fan speed:

[0044] 2)ipmitool.exe-I lanplus-H ip-U username-P password raw 0x30 0x300x020xff 0xThe percentage of the rotation speed in hexadecimal

[0045] The monitoring module may include but is not limited to components such as sensors, such as a temperature sensor, a speed sensor, a current sensor, etc. Through the monitoring module, the test device can obtain information such as the actual temperature, actual speed, and actual current of the fan.

[0046] based on Figure 1 The structure shown in the figure is combined with the reference Figure 2 , which is a flow chart of a fan testing method provided in some embodiments of the present disclosure. Figure 2 In the present invention, the fan testing method may include the following steps:

[0047] Step S201, obtaining the lowest test speed and the highest test speed of the fan.

[0048] In this embodiment, the minimum test speed may be the fan speed corresponding to when the server is in an idle state. The idle state refers to the state when the central processing unit or other hardware resources in the server are not executing tasks. In the idle state, the power consumption of the server can be low, and the heat dissipation can be less. The fan speed at this time can be used as the minimum speed during the operation of the fan. The maximum test speed may be the maximum speed allowed by the fan.

[0049] The maximum speed allowed by the fan can be burned into the complex programmable logic device of the fan. Therefore, by sending a command to the complex programmable logic device in the fan to obtain parameters, the maximum speed can be obtained, that is, the above-mentioned maximum test speed can be obtained. At the same time, the fan speed when the server is in an idle state can be obtained through server management software, etc., that is, the above-mentioned minimum test speed can be obtained.

[0050] In some other embodiments, the minimum test speed and the maximum test speed can also be set according to actual needs. For example, the maximum test speed can be less than the maximum speed allowed by the fan but greater than the minimum test speed. In these embodiments, the test device can provide a human-computer interaction interface. Through the human-computer interaction interface, the user can input the minimum test speed and the maximum test speed of the fan according to actual needs.

[0051] Step S202, according to the preset speed change logic, control the speed of the fan to cyclically change between the lowest test speed and the highest test speed for a target time, and collect actual operation data of the fan.

[0052] In this embodiment, the actual operation data may include at least one of an actual rotation speed, an actual current magnitude, an actual temperature, and an actual amplitude of the fan.

[0053] The speed change logic can be used to specify the change in fan speed and the duration of the fan at each speed. Based on different speed change logics, the fan speed can be controlled to change differently between the minimum test speed and the maximum test speed. For example, assume that the minimum test speed is 15 rpm and the maximum test speed is 250 rpm. Speed ​​change logic A specifies that the change in fan speed is 20 rpm and the duration of the fan at each speed is 25 seconds; speed change logic B specifies that the change in fan speed gradually increases according to the rule of 10 rpm, 20 rpm, and 30 rpm, and the duration of the fan at each speed is 20 seconds. Then:

[0054] 1) When the fan speed is controlled to change from the lowest test speed to the highest test speed according to the speed change logic A, the fan can be first controlled to run at a speed of 15 rpm for 25 seconds, and then the fan speed is increased by 20 rpm, and then the fan is controlled to run at a speed of 35 rpm for 25 seconds, and then the fan speed is increased by 20 rpm, and then the fan is controlled to run at a speed of 55 rpm for 25 seconds, and so on, until the fan speed reaches the highest test speed.

[0055] 2) When the fan speed is controlled to change from the lowest test speed to the highest test speed according to the speed change logic B, the fan can be first controlled to run at 15 rpm for 20 seconds, and then the fan speed is increased by 10 rpm, and then the fan is controlled to run at 25 rpm for 20 seconds, and then the fan speed is increased by 20 rpm, and then the fan is controlled to run at 45 rpm for 20 seconds, and so on, until the fan speed reaches the highest test speed.

[0056] It can be seen from the above speed change logic A and speed change logic B that the speed change rules of the fan are different according to different speed change logics.

[0057] Furthermore, within the target duration, the fan speed can be controlled to change cyclically between the lowest test speed and the highest test speed according to the speed change logic. The so-called cyclic change means that according to the speed change logic, the fan is controlled to change from the lowest test speed to the highest test speed, then the fan is controlled to change from the highest test speed to the lowest test speed, and then the fan is controlled to change from the lowest test speed to the highest test speed, and so on, until the target duration is reached.

[0058] According to different speed change logics, when the fan speed is controlled to cycle between the minimum test speed and the maximum test speed, the target duration can be the same or different. For example, according to speed change logic A, the fan speed can be controlled to cycle between the minimum test speed and the maximum test speed for 12 hours, according to speed change logic B, the fan speed can be controlled to cycle between the minimum test speed and the maximum test speed for 10 hours, and then according to speed change logic C, the fan speed can be controlled to cycle between the minimum test speed and the maximum test speed for 12 hours.

[0059] Since the fan speed is in a dynamic change process when it is controlled to cycle between the lowest test speed and the highest test speed according to the speed change logic, the fan speed needs to continuously respond to the speed adjustment within the target time to rotate at different speeds. In this way, on the one hand, the fan's speed switching ability, as well as the fan's response time and stability when the fan switches between different speeds can be effectively detected; on the other hand, it is equivalent to applying a certain performance pressure to the fan. In this way, when there is a potential fault problem in the fan, based on such a performance stress test, the actual operation data of the fan may be abnormal, and then, based on these abnormal phenomena, the fan with a potential fault problem can be determined.

[0060] Based on the above description, controlling the fan speed to cycle between the lowest test speed and the highest test speed for a target duration according to the speed change logic can also be understood as stimulating potential problems that may exist in the fan.

[0061] Generally speaking, whether the speed change logic is reasonably designed has a direct impact on whether the potential problems that may exist in the fan can be successfully triggered. Therefore, the corresponding speed change logic can be designed based on the maximum performance pressure that the fan can withstand. In the subsequent embodiments of the present disclosure, two better speed change logics are provided, which will not be repeated here.

[0062] Continue reading Figure 1 When the fan speed is controlled to cycle between the minimum test speed and the maximum test speed according to the speed change logic, the actual operation data of the fan can be collected through complex programmable logic devices and monitoring modules (such as current sensors, temperature sensors, etc.). When the fan may have a potential fault, the actual operation data of the fan may include more abnormal information, such as a high frequency of abnormal sudden changes in the actual current size, and the actual temperature is too high. When the fan does not have a potential fault, the actual operation data of the fan may include less abnormal information, or no abnormal information.

[0063] Step S203, obtaining theoretical operation data of the fan that matches the speed change logic.

[0064] In this embodiment, the theoretical operation data may include at least one of a theoretical rotation speed, a theoretical current magnitude, a theoretical temperature, and a theoretical amplitude of the fan.

[0065] Specifically, the theoretical operation data may refer to the normal operation data changes of the fan when the speed of the fan changes according to the speed change logic when there is no potential fault in the fan, such as normal speed change, normal current change, normal temperature change, normal amplitude change, etc. For example, as the speed of the fan gradually increases, the current of the fan will also gradually increase in proportion, and there will be no or less sudden current changes. For another example, when the speed of the fan is controlled to change from 20 rpm to 30 rpm, the speed of the fan will not suddenly change to 80 rpm, etc.

[0066] Since the theoretical speed of the fan is known based on the speed change logic, the theoretical operating data such as the theoretical current size, theoretical temperature and theoretical amplitude of the fan that match the speed change logic can be calculated based on relevant theoretical calculation formulas. For example, according to the calculation formula between the fan speed and the current size, the theoretical current size of the fan corresponding to the theoretical speed can be obtained according to the theoretical speed of the fan. For another example, according to the product characteristic curve of the fan, the theoretical temperature of the fan corresponding to the theoretical speed can be determined according to the theoretical speed of the fan.

[0067] Step S24, determining the test result of the fan according to the difference between the actual operation data and the theoretical operation data.

[0068] Specifically, the test result can be used to characterize whether the fan has a potential fault. According to the relevant description of step S22, when the fan has a potential fault, its actual operation data may not be completely the same as the theoretical operation data. For example, when the fan has a potential fault, when the fan speed is controlled to change from 20 rpm to 30 rpm, the actual speed of the fan may have a sudden change of 80 rpm at a higher frequency, etc., but in the theoretical speed of the fan, there will be no or a low frequency of 80 rpm. Therefore, by comparing the actual operation data with the theoretical operation data, and according to the difference between the two, the test result of the fan can be determined.

[0069] In summary, in the technical solutions of some embodiments of the present disclosure, when the speed of the fan is controlled to cycle between the lowest test speed and the highest test speed for a target time according to the speed change logic, the speed of the fan is in a dynamic change process, so that the fan needs to continuously respond to the speed adjustment to rotate at different speeds, which is equivalent to applying a certain performance pressure to the fan. In this way, when there is a potential fault problem in the fan, based on such a performance stress test, the actual operating data of the fan may show abnormal phenomena, and then, based on these abnormal phenomena, the fan with potential fault problems can be determined. In this way, fans with potential fault problems can be replaced or configured in advance to avoid server heat dissipation problems caused by fan failures, thereby improving the heat dissipation reliability of the server.

[0070] Combined with reference Figure 3 , is a schematic diagram of the cyclic change of the fan speed provided by some embodiments of the present disclosure. Figure 3 In step S202, according to the preset speed change logic, controlling the fan speed to cycle between the minimum test speed and the maximum test speed for a target duration may include:

[0071] During the target time, the fan speed is controlled to increase gradually so that the fan speed changes from the lowest test speed to the highest test speed, and the fan speed is controlled to decrease gradually so that the fan speed changes from the highest test speed to the lowest test speed.

[0072] Specifically, the fan speed may be controlled to change from the lowest test speed to the highest test speed in the following manner:

[0073] 11) Obtain the current first actual speed of the fan.

[0074] like Figure 1 As shown, the first actual rotation speed of the fan can be obtained through a rotation speed sensor or the like.

[0075] 12) If the first actual rotation speed does not reach the maximum test rotation speed, a first target rotation speed to be increased by the rotation speed of the fan is determined based on the first actual rotation speed.

[0076] In this embodiment, the first actual speed can be proportional to the first target speed. That is, the larger the first actual speed, the larger the first target speed; the smaller the first actual speed, the smaller the first target speed. Specifically, a speed of a first preset ratio of the first actual speed can be used as the first target speed. For example, 10% of the first actual speed is used as the first target speed. That is, when the first actual speed is 20 rpm, the first target speed is 2 rpm; when the first actual speed is 30 rpm, the first target speed is 3 rpm. And so on. When the first actual speed is high, the first target speed to be increased by the fan also increases accordingly, making the speed change of the fan more obvious, which is conducive to detecting potential fault problems of the fan. When the first actual speed is low, the first target speed to be increased by the fan also decreases accordingly, so as to avoid excessive changes in the speed of the fan and the omission of potential fault problems.

[0077] 13) When the fan rotates at a first actual speed for a first preset time, controlling the fan speed to increase to a first target speed.

[0078] In this way, on the one hand, during this time period, the actual operation data of the fan at various speeds can be collected, and on the other hand, the performance stress detection scenario of the fan can also be simulated.

[0079] In some embodiments, when the first actual rotation speed reaches the maximum test rotation speed, the fan can be controlled to rotate at the maximum test rotation speed for a first preset time, and then the fan can be controlled to change from the maximum test rotation speed to the minimum test rotation speed.

[0080] Specifically, the fan speed may be controlled to change from the highest test speed to the lowest test speed in the following manner:

[0081] 21) Obtain the second current actual speed of the fan.

[0082] 22) If the second actual rotation speed does not reach the minimum test rotation speed, a second target rotation speed at which the rotation speed of the fan is to be reduced is determined based on the second actual rotation speed.

[0083] 23) When the fan rotates at the second actual speed for the second preset time, the fan speed is controlled to decrease to a second target speed.

[0084] The above steps 21) to 23) are the reverse processes of steps 11) to 13), and the principles are basically similar, which will not be described here.

[0085] In this embodiment, the first preset time length is the same as the second preset time length.

[0086] In some other embodiments, the first preset duration is different from the second preset duration.

[0087] Combined with reference Figure 3 After controlling the fan speed from the highest test speed to the lowest test speed according to the above steps 21) to 23), it can be determined whether the cyclic change duration of the fan speed reaches the target duration. If it reaches the target duration, the test ends; if it does not reach the target duration, the fan speed is controlled from the lowest test speed to the highest test speed according to the above steps 11) to 13), and the fan speed is controlled from the highest test speed to the lowest test speed according to the above steps 21) to 23, and the cycle is repeated until the target duration is reached.

[0088] exist Figure 3 In the illustrated embodiment, by controlling the fan speed to change successively between the lowest test speed and the highest test speed, the fan speed adjustment function can be detected, and then based on the actual operation data of the fan, it can be determined whether the fan has a potential fault.

[0089] Combined with reference Figure 4 , is a schematic diagram of the cyclic change of fan speed provided in some other embodiments of the present disclosure. Figure 4 and Figure 3 Basically similar, the main differences are: Figure 4 In the process, after each change in the speed of the controlled fan, it is necessary to determine whether the speed difference between the actual speed of the fan and the theoretical speed that the fan should reach reaches the speed difference threshold. If so, the fan test process is exited and information indicating the test abnormality is prompted. If not, the fan test continues.

[0090] Specifically, assuming that the first preset ratio is 10%, when the fan changes from the lowest test speed to the highest test speed, the calculation formula of the first theoretical speed can be shown as expression (1):

[0091] y1=x1+x1*10% (1)

[0092] Wherein, y1 represents the first theoretical speed, and x1 represents the first actual speed. The meaning of expression (1) is: on the basis of the first actual speed, after increasing the first target speed of 10%*the first actual speed, the obtained theoretical speed should be y1. If the test equipment sends a control instruction to the fan, and controls the fan speed to increase the first target speed, the difference between the actual fan speed detected by the sensor and the theoretical speed reaches the speed difference threshold, indicating that the speed adjustment of the fan has failed. In this case, the fan test process can be exited. In this way, invalid tests on the fan can be reduced.

[0093] Corresponding to expression (1), when the fan changes from the highest test speed to the lowest test speed, the calculation formula of the second theoretical speed can be shown as expression (2):

[0094] y2=x2-x2*10% (2)

[0095] Wherein, y2 represents the second theoretical speed, and x2 represents the second actual speed. The meaning of expression (2) is: on the basis of the second actual speed, after reducing the second target speed by 10%*the second actual speed, the second theoretical speed obtained should be y. If the test equipment sends a control instruction to the fan, and controls the fan speed to reduce the second target speed, the difference between the actual fan speed detected by the sensor and the second theoretical speed reaches the difference threshold, indicating that the speed adjustment of the fan has failed. In this case, the fan test process can be exited. In this way, invalid tests on the fan can be reduced.

[0096] Combined with reference Figure 5 , is a schematic diagram of the cyclic change of fan speed provided in some other embodiments of the present disclosure.

[0097] based on Figure 5 In step S202, according to the preset speed change logic, controlling the fan speed to cycle between the minimum test speed and the maximum test speed for a target duration may include:

[0098] determining a speed difference between a maximum test speed and a minimum test speed;

[0099] When the fan rotates at the lowest test speed for a third preset time, controlling the speed of the fan to increase the speed difference so as to adjust the speed of the fan from the lowest test speed to the highest test speed;

[0100] When the fan rotates at the maximum test speed for a fourth preset time period, the speed of the fan is controlled to reduce the speed difference, so as to adjust the speed of the fan from the maximum test speed to the minimum test speed.

[0101] Figure 5 and Figure 3 The difference is: Figure 3 It controls the fan speed to change gradually between the lowest test speed and the highest test speed. Figure 5 The fan speed is controlled to jump directly from the lowest test speed to the highest test speed, or the fan speed is controlled to jump directly from the highest test speed to the lowest test speed. In this way, different test scenarios for the fan can be constructed. Based on different test scenarios, different potential faults that may exist in the fan can be detected, and the detection of the fan is more accurate.

[0102] Specifically, with Figure 3 akin, Figure 5In the process, after controlling the fan speed to change from the highest test speed to the lowest test speed, it is necessary to determine whether the fan cycle change duration reaches the target duration. If so, exit; if not, continue the test. The relevant principles are not described here.

[0103] In this embodiment, the third preset time length is the same as the fourth preset time length.

[0104] In some other embodiments, the third preset time length is different from the fourth preset time length.

[0105] Combined with reference Figure 6 , is a schematic diagram of the cyclic change of fan speed provided in some other embodiments of the present disclosure. Figure 6 and Figure 5 Basically similar, the main difference is: after each change in the speed of the fan, it is necessary to determine whether the speed difference between the actual speed of the fan and the theoretical speed that the fan should reach reaches the speed difference threshold. If so, exit the fan test process and prompt information indicating the test abnormality. If not, continue to test the fan. For related principles, see Figure 4 The description is not repeated here.

[0106] Furthermore, in some other embodiments, each time the speed of the fan is controlled to change, the method of the present disclosure may further include:

[0107] Randomly determine the amount of change in fan speed and the duration of fan operation at each speed;

[0108] According to the randomly determined change amount, the rotation speed change of the fan is controlled, and according to the randomly determined operation time, the operation time of the fan at each rotation speed is controlled.

[0109] Relative to Figures 3 to 6 The fan speed is controlled to change according to a specific rule. In this embodiment, the fan speed is controlled randomly. Figures 3 to 6 Potential faults that cannot be detected in the method shown may be detected in this embodiment, and the detection of the fan is more comprehensive.

[0110] In some embodiments, determining the test result of the fan according to the difference between the actual operation data and the theoretical operation data in step S204 may include:

[0111] If the difference between the actual operating data and the theoretical operating data at the same speed reaches the data difference threshold, it is determined that the fan has a potential fault;

[0112] If the difference between the actual operating data and the theoretical operating data at the same speed does not reach the data difference threshold, it is determined that there is no potential fault in the fan.

[0113] Specifically, when any of the following situations occurs, it can be determined that the fan has a potential fault, otherwise, it can be determined that the fan does not have a potential fault:

[0114] When the actual operation data includes the actual rotation speed of the fan, the rotation speed difference between the actual rotation speed and the theoretical rotation speed at the same rotation speed reaches a first data difference threshold;

[0115] When the actual operation data includes the actual current of the fan, the speed difference between the actual current and the theoretical current at the same speed reaches a second data difference threshold;

[0116] When the actual operation data includes the actual temperature of the fan, the temperature difference between the actual temperature and the theoretical temperature at the same speed reaches a third data difference threshold;

[0117] When the actual operation data includes the actual amplitude of the fan, the amplitude difference between the actual amplitude and the theoretical amplitude at the same rotation speed reaches a fourth data difference threshold.

[0118] In some embodiments, the actual operation data includes a plurality of actual operation data of the fan at the same rotation speed;

[0119] When determining the test result of the fan according to the difference between the actual operation data and the theoretical operation data, the method further includes:

[0120] According to a plurality of actual operating data at the same speed, an average value of the operating data of the fan at the corresponding speed is obtained;

[0121] The test result of the fan is determined according to the distribution of the data sizes of the plurality of actual operation data relative to the average value of the operation data.

[0122] Specifically, multiple actual current magnitudes at the same speed are used as an example for explanation. If the absolute value of the difference between the actual current magnitudes exceeding a specified number and the average current magnitude among the multiple actual current magnitudes is greater than a threshold, it can be considered that the frequency of abnormal current mutations of the fan is high, and the fan may have a potential fault problem; otherwise, it can be considered that the fan does not have a potential fault problem.

[0123] The fan test results are determined by the distribution of actual operating data, and the results are relatively accurate and objective.

[0124] In summary, combined with reference Figure 7 , a flowchart of a fan test provided for some embodiments of the present disclosure.

[0125] Figure 7 In the fan test, the following steps are included:

[0126] Step S701, build a test environment and install a monitoring module on the fan.

[0127] Specifically, when setting up the test environment, it is necessary to check whether the power supply, grounding, etc. of the test environment meet the safety standards to ensure the safety of the test environment.

[0128] Also, it is necessary to verify whether the monitoring module can accurately read and record data to ensure that subsequent tests proceed normally.

[0129] Step S702: The server is turned on and enters the idle state.

[0130] Specifically, before testing, it is necessary to ensure that the server operating system has been running stably for a period of time without abnormalities. At the same time, shut down all unnecessary background services and applications to reduce interference with the test results. In simple terms, it is to prevent the server from being in an overheated state, so as to avoid the baseboard control manager controlling the fan to run faster when the server is overheated, resulting in the inability to control the fan speed as needed.

[0131] Step S703, clear the server operating system (ie, OS) and baseboard control manager (BMC) logs, and create a new fan speed and current monitoring log.

[0132] Step S704, starting the fan current monitoring process and the fan speed monitoring process of the baseboard manager control (BMC).

[0133] Step S705, controlling the rotation speed of the fan to change gradually, so that the rotation speed of the fan cycles between the lowest test rotation speed and the highest test rotation speed for a target time length.

[0134] Step S706, controlling the fan speed to switch between the lowest test speed and the highest test speed, and looping for a target time.

[0135] Step S707, collect log information for data analysis to obtain test results.

[0136] This completes the description of the method disclosed herein. The method disclosed herein can be used to detect the fan in the server before the server leaves the factory, so as to ensure the heat dissipation reliability of the server leaving the factory. Of course, the method disclosed herein can be used to detect the fan in the server during the daily maintenance of the server. Here, the use scenario of the method disclosed herein is not limited.
