In order to facilitate understanding of the embodiments of the present application and further analyze and propose technical problems to be specifically solved by the present application, the following briefly introduces related technical solutions of the present application.

However, in the related art, a serial line between the PC and the server is required to be connected to control the fan rotation speed, and it is difficult to flexibly adjust the fan rotation speed depending on the serial line.

In summary of the defects and shortcomings of the related art, the embodiments of the present application mainly solve the following technical problems: how to more flexibly adjust the rotational speed of the server fan to reduce the noise of the server fan.

Based on the above technical problem, the embodiment of the present application is mainly applied to a server test scenario, please refer to fig. 2, fig. 2 is an application environment schematic diagram of a method for reducing noise of a server in the test scenario provided by the embodiment of the present application, as shown in fig. 2, the environment may include a server, a PC and a noise monitor, where the noise monitor is used to monitor noise of a fan on a fan board of the server and display a noise decibel value in real time; the hanging lug of the server is provided with a test mode switching button which is electrically connected with the BMC, the BMC can detect a signal triggered by the button when maintenance personnel or testing personnel trigger the button, so that the server in work enters a test mode, and the BMC can adjust the rotating speed of a fan on a fan plate to reduce fan noise when the server enters the test mode; the server and the PC can be connected through a serial port line, a maintenance worker or a test worker can enter the BMC management system through software (such as a browser or an application program) on the PC, a test mode switching button is also arranged on an interface of the BMC management system, and the maintenance worker or the test worker can enable the server in work to enter a test mode by triggering the test mode switching button on the BMC interface.

The following describes in detail a method for reducing server noise in a test scenario and related devices provided in the embodiments of the present application with reference to the accompanying drawings.

Referring to fig. 3, fig. 3 is a schematic flowchart of a method for reducing server noise in a test scenario according to an embodiment of the present disclosure, where the method may be applied to the environment shown in fig. 2, and as shown in fig. 3, the method may include steps 301 to 303:

301: the BMC obtains a test mode instruction, and the test mode instruction is used for indicating the BMC to enter a test mode.

In the embodiment of the application, the test scene refers to that a maintenance worker or a testing worker executes a test task of the server in the machine room, the server has a test mode, and the BMC can enable the server to enter the test mode by one key based on the triggering of the test mode switching button. The test mode switching button can be an external button arranged on a hanger of the server or a button arranged on a BMC interface. According to the noise decibel value displayed by the noise monitor, a maintenance worker or a test worker can trigger a test mode switching button on a hanger of the server to enable the test mode switching button arranged on the BMC interface to be triggered under the condition that the PC end enters the BMC interface (for example, under the condition that the noise of a fan of the server exceeds 90 decibels). When the BMC detects a signal triggered by the test mode switching button, a test mode instruction is obtained, and the test mode instruction is used for indicating the BMC to control the server to enter a test mode or enabling the server to enter the test mode through interaction with a server system. For example, the BMC may calculate the fan noise according to the rotation speed of the fan by using an existing noise calculation formula, and display the fan noise on the BMC interface, and the maintenance personnel or the test personnel may trigger the test mode switching button according to the fan noise displayed on the BMC interface. In the embodiment, a maintenance worker or a test worker can enable the server to enter the test mode by triggering the test mode switching button on the hangers or the BMC interface of the server, and the operation is convenient and rapid.

302: the BMC obtains a target noise value.

In the embodiment of the application, the target noise value can be a noise value appointed by a maintenance worker or a testing worker before the testing mode is started; or after the test mode is started, when the maintenance personnel or the test personnel adjust to different gears through an external button on a hanger of the server or a button arranged on a BMC interface, the gear corresponds to a noise value; or may also be a default value such as: 90 decibels. The BMC can acquire a target rotating speed value corresponding to the target noise value and then sends a fan rotating speed adjusting instruction to a fan plate of the server. That is, the BMC may automatically send a fan speed adjustment command based on a default value or a set value, where the fan speed adjustment command is used to instruct the fan plate to adjust the speed of the fan, so that the speed of the fan is lower than or equal to the target speed value.

303: and the BMC executes a fan adjusting strategy according to the target noise value, wherein the adjusting strategy is used for setting the rotation number of the fan of the server.

In some possible embodiments, when entering the test mode, if the server is executing the test task and/or there is a test task in the queue, the BMC detects a lowest noise value required by the executing test service, and if the value is less than or equal to the target noise value, the BMC sends a fan speed adjustment instruction to the fan board, so that the test task can be ensured to be normally executed even when the fan speed is reduced, and if the value is greater than the target noise value, the BMC does not send the fan speed adjustment instruction, so as to avoid that the test task cannot be normally executed due to the reduction of the fan speed. Illustratively, as shown in fig. 4A, the BMC interface displays that the server is executing a signal integrity/power integrity test service, the progress bar displays that the completion progress is 90%, if the minimum fan speed required by the signal integrity/power integrity test is a1, the noise generated by a1 is the lowest noise value n1, and if n1 is less than or equal to the target noise value and the current noise of the server fan exceeds the target noise value, the BMC sends a fan speed adjustment instruction to the fan board to adjust the fan speed to a1; if n1 is larger than the target noise value, it indicates that the current execution signal integrity/power integrity test cannot reduce the fan rotation speed, and the BMC does not send a fan rotation speed adjustment instruction to the fan plate.

Optionally, as shown in fig. 4B, for example, when detecting that the lowest noise value required by the executing test service is greater than the target noise value, the BMC indicates that the currently executed signal integrity/power integrity test requires a large wind speed to meet the heat dissipation requirement, and at this time, the BMC may pop up a prompt box to inquire whether to interrupt the test service, and if the selection is yes by the maintenance person or the test person, the BMC stops the signal integrity/power integrity test service in response to the operation, and sends a fan speed adjustment instruction to the fan board; if the maintenance personnel or the testing personnel select no, the signal integrity/power integrity test service needs to be executed continuously, and the BMC does not send a fan rotating speed adjusting instruction to the fan plate so as to keep the current rotating speed.

Optionally, as shown in fig. 4C, for the testing service (e.g., signal integrity/power integrity test) being performed by the server, the BMC may display the minimum required fan speed a1 and the corresponding noise floor n1 on the BMC interface.

Optionally, the BMC may further display at least one recommended service on the BMC interface, where noise of the at least one recommended service is less than a target noise value, for example, as shown in fig. 4D, the at least one recommended service may be a signal integrity test, a power integrity test, and the like, a maintenance person or a test person may select a part or all of the at least one recommended service, the BMC may terminate the test task being executed based on the selection of the maintenance person or the test person, if the selected recommended service is one recommended service, the BMC immediately executes the service, if the selected recommended services are multiple recommended services, the BMC adds the multiple recommended services to the task queue, and sequentially executes the multiple recommended services based on the selection of the user; and if the executing test task can not be suspended, adding the selected at least one recommended service into a task queue by the BMC, and executing the selected at least one recommended service after the current test task is executed. Optionally, the BMC may further display all the test services on the BMC interface, and highlight the test services whose noise floor is smaller than the target noise value, so as to indicate that the services may be executed in the test mode; test transactions having a noise floor greater than or equal to the target noise value are grayed out to indicate that they cannot be executed in the test mode.

In some possible embodiments, when entering the test mode, if the server has no test task being executed or no test task is in the queue, the BMC directly sends a fan speed adjustment instruction to the fan board to adjust the speed of the fan to be lower than the target speed value corresponding to the target noise value.

Optionally, as shown in fig. 4D, for example, the BMC may still display at least one recommended service on the BMC interface, where noise of the at least one recommended service is less than the target noise value, the service person or the tester may select some or all of the at least one recommended service, and the BMC may execute the some or all of the services based on the selection of the service person or the tester, such as: if one recommended service is selected, the BMC immediately executes the service, if a plurality of recommended services are selected, the BMC adds the recommended services into a task queue, sequentially executes the recommended services based on the selection of a user, and sends a fan rotating speed adjusting instruction to the fan plate under the condition that maintenance personnel or testing personnel select at least one recommended service.

Optionally, after the server enters the test mode, the BMC may shield a target test service whose noise floor is greater than or equal to a target noise value, where the target test service is a test service whose ratio of power to overall power of the server is greater than or equal to a preset threshold. Such as: the target test service may be a pressure test, a stability test, and the like, and the preset threshold may be 50% or 75%, and the threshold is set by a maintenance person or a tester after entering the BMC management system (specifically, before step 301). It should be appreciated that the stress test and the stability test generally require that the CPU and the memory are at full speed, and that the full speed operation of the CPU and the memory can reach more than 95% of the speed of the whole machine, and the power in this scenario is also relatively high. In the test mode, the power of the server generally cannot meet the requirements of the pressure test and the stability test, so that the BMC can shield the target test service under the condition that the server enters the test mode, so as to develop the test service of the low-speed signal and the power signal without a full configuration scene. For example, as shown in fig. 5A, the BMC may display the currently unexecutable test service on the BMC interface, such as: in the pressure test and the stability test, when a maintenance worker or a test worker needs to set or operate a certain displayed service, for example, as shown in fig. 5B, the BMC pops up a window asking whether to execute the service, and if the selection is yes, the BMC does not need to send a fan speed adjustment instruction, and if the selection is no, the BMC sends a fan speed adjustment instruction.

It should be noted that, in some possible embodiments, in the test mode starting process, a maintenance person or a test person may modify the target noise value, or modify the rotation speed values corresponding to different gears of the manual fan adjustment button, based on which the target noise values corresponding to different gears may also change, so that the BMC needs to perform an operation of obtaining the target noise value in real time, and then perform a fan adjustment policy according to the target noise value.

In some possible embodiments, after entering the test mode, the maintenance person or the test person may trigger the test mode switching button on the ear or on the BMC interface again to turn off the test mode, optionally, in the test mode, when the BMC detects that the test mode switching button is triggered, the interface shown in fig. 5C may be popped up to inquire whether the maintenance person or the test person finishes the test mode, if so, the test mode is immediately finished to enter the normal operating state, and if not, the test mode is maintained. Optionally, the query may also be performed in a voice broadcast manner, in the test mode, when the BMC detects that the test mode switching button is triggered, the BMC queries, in a voice manner, whether the maintenance worker or the test worker ends the test mode, optionally, the BMC may recognize the voice of the maintenance worker or the test worker, and determines whether to end the test mode based on a voice recognition result, optionally, the BMC may further prompt the maintenance worker or the test worker to end the test mode by pressing two test mode switching buttons on the BMC interface, and long-pressing the test mode switching button on the BMC interface indicates to maintain the test mode, so as to facilitate remote operation. Optionally, for the test task being executed displayed on the BMC interface, a maintenance person or a test person may double-click the test task, then pop up parameters such as a performance index and an execution progress tested by the test task, and the maintenance person or the test person double-clicks the test task again, that is, hide the parameters such as the performance index and the execution progress tested by the test task. Optionally, in the test mode, the BMC detects whether there is a currently executed test task, and if there is no test task currently executed within a certain period of time, exemplarily, as shown in fig. 5D, pops up an inquiry interface whether to end the test mode, and the maintenance staff or the test staff may select to directly end the test mode or select to keep the test mode.

It should be understood that, in the case that the fan plate receives the fan speed adjustment instruction, the fan plate may analyze the instruction and then obtain a target speed value of the fan, so as to adjust the speed of the fan to the target speed value. Such as: the target speed value may be 30% of the full speed of the fan. Illustratively, the fan board may cause the speed of the fan to be less than the target speed value by adjusting a Pulse Width Modulation (PWM) signal of the fan based on the fan speed adjustment command. After the fan of the control server reduces the rotating speed, maintenance personnel or testing personnel can start to test the server. For example, the BMC may also control an on-site status of a fan on a fan board and display a speed of the fan on the BMC interface. In this embodiment, when the server enters the test mode, the BMC may adjust the rotation speed of the server fan to a target rotation speed value according to a preset target noise value, so that the fan noise is lower than the target noise value (for example, 90 db).

Illustratively, the method further comprises:

Specifically, in the example of fig. 5B, if the maintenance staff or the testing staff selects to execute the target test service such as the pressure test and the stability test, the BMC outputs, to the maintenance staff or the testing staff, the first prompt information indicating that the CPU of the server is in the down-conversion working state and the second prompt information indicating that the CPU of the server is in the off-conversion working state under the condition that the control server starts the target test service, as shown in fig. 5E, the BMC may display the first prompt information on the BMC interface first, and then display the second prompt information after several seconds. Certainly, the BMC may also display the first prompt message and the second prompt message at the same time, or put the first prompt message and the second prompt message in the same pop-up window for display, which is not limited herein. For example, the service person or the tester may also start the target test service by a manual or program instruction. In the embodiment, under the condition that the server starts the target test service, the first prompt information that the CPU is in the frequency reduction working state is output, and maintenance personnel, testing personnel or users can be prompted not to adjust the rotating speed of the fan at will, so that the CPU is prevented from being in the speed reduction working state; in addition, the second prompt information for closing the test mode is output, so that maintenance personnel or test personnel can close the test mode conveniently, and development of target test business is facilitated.

It can be seen that, in the embodiment of the present application, the BMC controls the server to enter the test mode when acquiring the test mode instruction, then acquires the target noise value, and executes the fan adjustment policy according to the target noise value, so as to reduce the number of revolutions of the fan of the server. Maintenance personal or tester can adjust the rotational speed of server fan without input speed governing instruction like this, can promote the efficiency of the rotational speed regulation of fan, under the condition that the server got into test mode, can carry out corresponding regulation strategy, make fan speed drop to predetermine under the rotational speed to reduce fan noise, when having promoted the flexibility of server fan speed regulation, can also reach the effect that the noise that the effective control fan rotational speed produced was realized to a key. In addition, after the test mode is started, the server fan is in a low-speed working mode, the fan noise is controlled to be under a preset decibel value, the heat dissipation of the CPU is effectively guaranteed, and the comfort level of the test environment can be improved.

It should be noted that, the embodiment shown in fig. 3 is described by using a BMC as an execution main body, and the method for reducing server noise in a test scenario provided in the embodiment of the present application may also be implemented by other software or hardware, for example: complex Programmable Logic Devices (CPLDs), and the like.

Referring to fig. 6, fig. 6 is a schematic flowchart of another method for reducing server noise in a test scenario provided by the embodiment of the present application, and as shown in fig. 6, the method may include steps 601 to 603:

601: the BMC responds to the trigger of a test mode switching button to acquire a test mode instruction, and the test mode switching button is arranged on a hanger of the server and/or on an interface of the BMC;

602: the BMC acquires a target noise value;

603: and the BMC executes a fan adjusting strategy according to the target noise value, wherein the adjusting strategy is used for setting the rotation number of the fan of the server.

The specific implementation manner of steps 601-603 can refer to the description in the embodiment shown in fig. 3, and can achieve the same or similar beneficial effects, which is not described herein again.

To facilitate understanding, one example of server fan speed adjustment is provided below:

referring to fig. 7, when the server is in a normal operating state, the BMC or CPLD monitors noise of the server fan and displays a noise decibel value, a maintenance worker or a test worker triggers a test mode switching button on a hanger of the server or on a BMC interface when the fan noise exceeds 90 decibels, the BMC or CPLD detects that the test mode switching button is triggered, so that the server enters a test mode, and when the BMC or CPLD enters the test mode, the BMC or CPLD reduces the rotation speed of the fan according to a default noise value (90 decibels) to make the fan noise lower than 90 decibels, and then the maintenance worker or the test worker starts to test the server. It should be appreciated that in the event that the fan noise is below 90 db, the test mode switch button is not triggered and the server continues to operate normally, and that in the event that the test mode switch button is triggered but the server does not successfully enter the test mode, the server is also operating normally.
