Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
Fig. 1 is a flowchart illustrating steps of a server power fan control method according to an exemplary embodiment. As shown in fig. 1, the server power fan control method specifically includes the following steps:
And 101, acquiring the rotating speed information of a system fan in the server.
In the disclosed embodiments, a server may refer to a computer for managing computing resources. The server may have a heat dissipation system disposed therein. The heat dissipation system may be a combination of components in the server for dissipating heat. The heat dissipation system of the server can comprise a system fan and a power supply fan. The system fan can radiate heat for high-power heating devices such as a central processing unit (central processing unit, CPU) and the like. The system fan may be controlled by a system fan control unit, which may refer to a baseboard management controller (Baseboard Manager Controller, BMC) of the electronic device. The power supply fan may dissipate heat for the power supply. The power fan may be controlled by a power fan control unit of the server.
The rotational speed information may refer to a real-time rotational speed of the system fan. The rotation speed information may be specifically characterized by a pulse width modulation (Pulse width modulation, PWM) signal or a Duty Cycle signal (Duty Cycle), or may be characterized by other parameters, which are not limited by the specific representation of the rotation speed in the embodiments of the disclosure.
In the embodiment of the disclosure, the system fan control unit and the power supply fan control unit are in communication connection, namely, the system fan control unit and the power supply fan control unit are communicated with each other by fan information, and can mutually transmit the fan information such as running state, rotating speed information and the like, so that coordinated linkage control of the system fan control unit and the power supply fan control unit based on software control logic can be realized. In this step, the power fan control unit in the server may acquire the rotational speed information of the system fan sent by the system fan control unit in real time, and may subsequently adjust the real-time rotational speed of the power fan based on the rotational speed information.
102, Determining a target rotating speed corresponding to the rotating speed information based on a preset rotating speed corresponding relation; the preset rotation speed corresponding relation is the rotation speed corresponding relation of the system fan and the power supply fan in the server in the wind flow balance state.
In the embodiment of the present disclosure, the target rotation speed may refer to a rotation speed of a power supply fan corresponding to rotation speed information of a system fan in a wind flow balance state. The wind flow balance state can be a state that the system fan and the power supply fan can normally intake and discharge wind and no phenomena of wind robbing and backflow exist. The preset rotational speed correspondence may refer to a correspondence between rotational speed information of the system fan and a target rotational speed of the power supply fan in a wind flow equilibrium state. The preset rotation speed corresponding relation can be obtained based on an actual test experiment of the running process of the server, and the specific rotation speed corresponding relation and the determining mode are not limited in the embodiment of the disclosure.
In one implementation, the power supply fan and the system fan of the electronic device are typically disposed at the rear or front window of the electronic device at the same time, for hot plug maintenance requirements of the system fan and the power supply or system configuration requirements. However, the system fan is far stronger than the power fan, and the power fan only operates according to the self fan regulation strategy, cannot control the rotation speed of the system fan in a coordinated manner, and normally operates at a lower rotation speed level, so that the phenomena of system fan wind-rush and power fan backflow occur, on one hand, the continuous hot wind superposition accumulation in the power supply and the hot wind incapability of being effectively removed, and on the other hand, the system fan cannot pump heat of a heating device in the system according to the original preset wind flow route, heat accumulation can be generated in the system, the heating device cannot be effectively cooled, and the system is overheated.
In the embodiment of the present disclosure, after receiving the rotation speed information of the system fan, the power fan control unit in the server may input the rotation speed information into the preset rotation speed corresponding relation based on the preset rotation speed corresponding relation, calculate to obtain the target rotation speed of the power fan, and may subsequently adjust the power fan based on the target rotation speed. Therefore, based on real-time rotational speed information of the system fan, the target rotational speed of the power fan is determined by combining the preset rotational speed corresponding relation, the system fan and the power fan can be ensured to be always in a wind flow balance state, no phenomena of wind rush and backflow exist, and the heat dissipation effect of the heat dissipation system is ensured.
And step 103, adjusting the rotating speed of the power supply fan according to the target rotating speed.
In the embodiment of the disclosure, after determining the target rotation speed according to the rotation speed information of the system fan and the preset rotation speed corresponding relation, the power fan can be adjusted to the target rotation speed, so that the power fan and the system fan are in a rotation speed balance state.
In summary, according to the method for controlling the power fan of the server provided by the embodiment of the present disclosure, the rotation speed information of the system fan in the server is obtained; determining a target rotating speed corresponding to the rotating speed information based on a preset rotating speed corresponding relation; the preset rotation speed corresponding relation is the rotation speed corresponding relation of the system fan and the power supply fan in the server in the wind flow balance state; and adjusting the rotating speed of the power supply fan according to the target rotating speed. In this way, in the embodiment of the disclosure, by acquiring the rotation speed information of the fan of the server system and determining the target rotation speed of the power supply fan based on the rotation speed information, the system fan and the power supply fan can be ensured to be always in a wind flow balance state, and the phenomena of wind rush and power supply fan backflow of the system fan are avoided; meanwhile, as no additional structural device is needed, the hardware cost and the space are saved, and the whole heat dissipation effect can be ensured.
Optionally, in an embodiment of the present disclosure, step 102 may specifically include the following steps 1021 to 1022:
step 1021, detecting the current state of the power fan.
In the embodiment of the present disclosure, the current state may refer to a real-time state in which the power fan is operated or stopped. Before determining the target rotational speed of the power supply fan corresponding to the rotational speed information of the system fan, it may be first determined whether the power supply fan is running.
Step 1022, if the current state of the power fan is an operation state, determining a target rotation speed corresponding to the rotation speed information based on the preset rotation speed corresponding relation.
In the embodiment of the disclosure, when the current state of the power fan is an operation state, a subsequent rotational speed adjustment process of the power fan may be performed, that is, a target rotational speed is calculated and the rotational speed of the power fan is set to the target rotational speed. When the current state of the power fan is in a stop state, the determination process of the target rotating speed is not required to be executed, and the rotating speed of the power fan is not required to be regulated. Therefore, system resources can be saved, invalid transmission of signals is avoided, and the accuracy of linkage control of the system fan and the power supply fan is ensured.
In the embodiment of the disclosure, detecting the current state of a power supply fan; and if the current state of the power supply fan is the running state, determining the target rotating speed corresponding to the rotating speed information based on the preset rotating speed corresponding relation. Thus, in the embodiment of the disclosure, the subsequent calculation process of the target rotating speed can be executed under the condition of the running state of the power fan, so that invalid data transmission and unnecessary calculation processes can be avoided, system resources are saved, and the accuracy of linkage control of the system fan and the power fan can be ensured.
Optionally, in an embodiment of the present disclosure, before step 102, the server power fan control method may further include the following steps S21 to S24 to generate:
and S21, acquiring a first test rotating speed aiming at the power supply fan, and operating the power supply fan according to the first test rotating speed.
In the embodiment of the present disclosure, the first test rotational speed may refer to a test rotational speed of a server power fan.
Step S22, a second test rotating speed for the system fan is obtained, and the system fan is operated according to the second test rotating speed.
In the embodiment of the present disclosure, the second test rotational speed may refer to a test rotational speed of a fan of the server system.
Specifically, the preset rotation speed corresponding relation can be detected by manually carrying out experiments on the heat dissipation system of the server. The specific test process can be as follows: setting a second test rotating speed for the system fan, setting a first test rotating speed for the power fan, and judging whether the system fan and the power fan are in a wind flow balance state or not. The test rotation speed can be set based on the normal rotation speed of the electronic equipment in the normal working state, and can also be flexibly set based on actual test requirements, and the embodiment of the disclosure is not limited to this. The wind flow balance state judgment can be manually judged by a tester to judge whether the wind rush and the wind return phenomenon exist, if the wind rush and the wind return phenomenon do not exist, the system fan and the power supply fan are determined to be in the wind flow balance state, and if the wind flow balance state does not exist, the system fan and the power supply fan are determined to be not in the wind flow balance state.
Step S23, recording a corresponding relationship between the second test rotational speed and the first test rotational speed when the system fan and the power fan are in a wind flow balance state, so as to generate the preset rotational speed corresponding relationship.
In the embodiment of the disclosure, when the system fan and the power supply fan are determined to be in the wind flow balance state, the corresponding relation between the second test rotating speed and the first test rotating speed at the moment can be recorded, after the recording is completed, the second test rotating speed can be updated, the first test rotating speed corresponding to the updated second test rotating speed in the wind flow balance state is determined, and the recording process is continuously executed. In this way, by continuously recording the corresponding relation between the second test rotating speed and the first test rotating speed in the wind flow balance state, a plurality of groups of corresponding relations can be directly generated into discrete preset rotating speed corresponding relations in the form of a data table, and continuous preset rotating speed corresponding relations can be obtained through calculation modes such as function fitting and the like.
And step S24, under the condition that the system fan and the power supply fan are not in the wind flow balance state, updating the first test rotating speed until the condition that the system fan and the power supply fan are in the wind flow balance state is reached.
In the embodiment of the disclosure, when it is determined that the system fan and the power fan are not in the wind flow balance state, the first test rotation speed may be adjusted, and whether the updated power fan under the first test rotation speed and the updated system fan under the second test rotation speed are in the wind flow balance state is determined again, if not, the first test rotation speed is continuously updated until the condition that the system fan and the power fan are in the wind flow balance state is reached, and at this time, the recording operation of the corresponding relationship between the second test rotation speed and the first test rotation speed under the wind flow balance state is executed again.
In the embodiment of the disclosure, a first test rotating speed for a power fan is obtained, and the power fan is operated according to the first test rotating speed; acquiring a second test rotating speed aiming at the system fan, and operating the system fan according to the second test rotating speed; recording the corresponding relation between the second test rotating speed and the first test rotating speed under the condition that the system fan and the power supply fan are in a wind flow balance state so as to generate a preset rotating speed corresponding relation; and under the condition that the system fan and the power supply fan are not in the wind flow balance state, updating the first test rotating speed until the condition that the system fan and the power supply fan are in the wind flow balance state is reached. Therefore, the corresponding relation between the second test rotating speed and the first test rotating speed in the wind flow balance state is determined by setting the second test rotating speed and continuously updating the first test rotating speed, the accuracy of the corresponding system fan and the power fan rotating speed can be ensured, and the accuracy of the subsequent linkage control of the system fan and the power fan is ensured.
Optionally, in the embodiment of the present disclosure, when the second test rotational speed is multiple, step S23 may be specifically implemented by the following step S231:
Step S231, fitting to obtain an objective function based on a plurality of groups of corresponding relations between the second test rotating speeds and the first test rotating speeds according to a preset function fitting method; the objective function is used for representing the preset rotating speed corresponding relation.
In the embodiment of the present disclosure, the preset function fitting method may be used to fit a preset rotational speed correspondence, and the specific fitting algorithm may be polynomial function fitting, least square fitting, or the like, which is not limited in the embodiment of the present disclosure. The objective function may be a function obtained by function fitting and used for representing a preset rotational speed correspondence. The objective function may be expressed as y=f (X), where X is rotational speed information of the system fan and Y is a target rotational speed of the power supply fan. After receiving the rotation speed information, the power supply fan control unit can guide the rotation speed information into the objective function, calculate the target rotation speed, adjust the power supply fan to the target rotation speed, and achieve the wind flow balance of the power supply fan and the system fan.
Specifically, when the preset rotational speed corresponding relation is generated, the corresponding relation between the second test rotational speed and the first test rotational speed in the at least two groups of wind flow balance states can be determined, and then the objective function can be obtained through a function fitting mode to represent the preset rotational speed corresponding relation. It should be noted that, for the servers, the parameters of the heat dissipation system such as power, rated voltage, rated current, and rotation speed range in the products of the same or similar model are often the same, so that the same preset rotation speed corresponding relation can be adopted for the electronic devices with the same parameters of the heat dissipation system, and one-by-one test is not required for all the servers, so that the test efficiency can be ensured, and the time of the testers can be saved.
In the embodiment of the disclosure, according to a preset function fitting method, fitting to obtain an objective function based on a corresponding relation between a plurality of groups of second test rotating speeds and first test rotating speeds; the objective function is used for representing a preset rotating speed corresponding relation. Therefore, through a function fitting mode, a continuous preset rotating speed corresponding relation can be obtained based on a small amount of data, the determining efficiency of the preset rotating speed corresponding relation in the wind flow balance state is improved, and a large amount of time of testers is saved.
Optionally, in an embodiment of the present disclosure, before step 101, the server power fan control method may further include the following steps S31 to S32:
Step S31, in response to a logic cancel instruction, adding a logic delete flag bit in control logic for a power supply fan; the logic deletion flag bit is used for canceling the rotating speed control logic in the control logic.
In the embodiment of the present disclosure, the initial control logic may refer to factory default fan control logic of a power fan control unit on a power fan in a server. A logic cancel instruction may be used to cancel the initial control logic. Logical delete flag bits may refer to flag bits added in the control logic that make the control logic no longer effective.
For example, when the initial control logic of the power fan control unit is canceled, a logic deletion flag bit may be added to the initial control logic, for example, the initial control logic is converted into a comment language by using a "#" character, so that the initial control logic of the power fan control unit can be invalidated, and the power fan can be controlled based on the written preset rotation speed correspondence.
And step S32, responding to a data writing instruction, and writing the preset rotating speed corresponding relation into the control logic.
In the embodiment of the disclosure, the data writing instruction may refer to an instruction of writing data input by a user. The tester can store the preset rotating speed corresponding relation generated by the test into the power supply fan control unit based on the data writing instruction, and the follow-up power supply fan control unit can adjust the power supply fan based on the preset rotating speed corresponding relation so as to realize linkage control of the power supply fan and the system fan.
In the embodiment of the disclosure, in response to a logic cancel instruction, a logic delete flag bit is added in control logic for a power supply fan; the logic deletion flag bit is used for canceling the rotating speed control logic in the control logic; and responding to the data writing instruction, and writing the preset rotating speed corresponding relation into the control logic. Therefore, the factory default fan control rule built in the server can be canceled, the change of the target rotating speed of the power supply fan along with the change of the rotating speed of the system fan is realized based on the corresponding relation of the preset rotating speed, the balance of the air flow of the power supply fan and the power supply fan is ensured to be always kept, the backflow phenomenon of the power supply fan is eliminated, and the heat dissipation effect of the heat dissipation system is ensured.
Optionally, in an embodiment of the present disclosure, an air outlet of the system fan and an air outlet of the power supply fan are located on the same plane of the server; and/or the air inlet of the system fan and the air inlet of the power supply fan are positioned on the same plane of the server.
In the embodiment of the disclosure, the air outlet or the air inlet of the system fan and the air inlet of the power supply fan may be in the same plane of the server, and specifically may refer to being arranged in parallel on a rear Input Output (IO) side or a front IO side of the server, and the like. Therefore, the system configuration space can be saved and the manufacturing cost can be reduced while the heat dissipation effect is ensured.
Optionally, in an embodiment of the present disclosure, a heat dissipation area covered by the system fan is larger than a heat dissipation area covered by the power supply fan.
In the embodiment of the disclosure, the heat dissipation area corresponding to the power supply fan can be smaller than the heat dissipation area corresponding to the system fan, so that the change of the rotation speed of the power supply fan along with the change of the rotation speed of the system fan can be realized, the balance of the wind flow and the backflow of the power supply fan are ensured to be kept all the time, and the heat dissipation effect of the heat dissipation system is ensured.
In the server, the power supply fan is used for radiating the power supply, and a plurality of heating devices with non-high power density can be arranged at the upstream of the power supply through proper system layout and air duct division in the server, so that the heat radiation of the upstream devices can be effectively solved by utilizing the power supply fan. And system fans are more specifically used to cool high power/high power density heat generating devices such as CPUs.
Illustratively, FIG. 2 shows a schematic diagram of a prior art power fan reflow and an implementation to address the reflow. As shown in fig. 2, in the first prior art solution, the power supply is completely physically isolated from other main components of the system by a structural member, and the interior of the electronic device (the server in fig. 2) is divided into two independent areas: the power supply is designed as an independent air channel area which occupies the width A1/A1', and the area is cooled by a power supply fan; the main components except the power supply only occupy the residual width A2/A2 'of the whole width A after A1 or A1' is removed, and the system fan radiates heat and the corresponding power density (power/radiating area) is increased. In the second prior art, the electronic device system may not be physically isolated, and the speed regulation of the power fan is not related to the rotational speed of the system fan, so that the risk that the power fan is blown back by the system fan is generated, a wind flow closed loop is formed between the power/power fan and the adjacent system fan, hot air is continuously accumulated in the power, the heat dissipation of the power is risky, and the heat of the upstream heating component cannot be timely pumped away by the system fan and is risky, so that the overall heat dissipation effect is poor.
In the server power fan control method disclosed by the embodiment of the disclosure, an information acquisition and association relationship is established between the power fan control unit of the power fan and the system fan control unit of the system fan, and a unidirectional or bidirectional feedback and response mechanism is designed, so that the target rotating speed of the power fan and the rotating speed information of the system fan are associated, and are always in a relatively balanced state, thereby avoiding the power fan from being blown or reflowed. In this way, the embodiment of the disclosure does not need to use a complex structural device, does not change the hardware layout and the number of devices of the server system, and can save the cost of the structural device compared with the prior art, thereby effectively reducing the cost of the server product. Meanwhile, the embodiment of the disclosure not only can eliminate risks caused by backflow of the power supply fan, but also can effectively utilize wind flow of the power supply fan to radiate heat to other devices arranged at the upstream of the power supply fan, change negative effects into positive effects, effectively reduce dependence on a system fan, effectively control the rotation speed and the power consumption of the system fan, optimize the energy consumption ratio (namely the power consumption/the system power) of the server system, and reduce the overall power consumption of the server.
