Detailed Description

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. This application is capable of embodiments in many different forms than those described herein and is therefore not limited to the specific embodiments disclosed below.

The application provides a method, a device and an electronic device for adjusting server power consumption in real time, and also provides a computer storage medium. Details are described in the following examples one by one.

In order to facilitate understanding of the method for adjusting the power consumption of the server in real time provided by the present application, a power consumption change rule of the server is introduced first.

During the operation of the server, various cooling fans are needed to dissipate heat from the server to ensure the normal operation of the server. For example: the server is integrally provided with a main cooling fan, and some processing chips with larger power consumption are provided with special cooling fans. The heat dissipation provided by these cooling fans is required to ensure that the server is in a normal operating state during operation, and above all, to ensure that the various electronic devices in the server are always operating within an allowable temperature range.

Since the cooling fan is an energy consuming element, the normal operation of the cooling fan can affect the overall power consumption of the server. Therefore, the overall power consumption of the server should be the sum of the cooling fan power consumption and the power consumption of the other various electronic devices in the server. During the operation of the server, the lower the rotation speed of the cooling fan, the lower the rotation speed corresponding to the cooling fan. In contrast, the lower the rotational speed of the cooling fan, the more power consumption of the various other electronic devices in the server gradually increases. That is to say, on the premise of meeting the working conditions of the server, the rotating speed of the cooling fan is increased, so that the heat dissipation effect of various electronic devices in the server is enhanced, the operating temperature of the electronic devices is reduced, and the power consumption of the electronic devices is effectively reduced; however, increasing the speed of the cooling fan increases its own power consumption. Besides the influence of the fan speed on the power consumption of the server, the power consumption of the server is related to a plurality of factors such as the load of the server in normal operation and the ambient temperature of the server. The power consumption of the server in the normal working state is not in a pure linear relation with the rotating speed of the cooling fan.

Therefore, on the premise of ensuring the normal operation of the server, selecting a proper rotating speed of the cooling fan to ensure that the overall power consumption of the server is low is an important technical problem in the field.

Please refer to fig. 1, which is a schematic diagram illustrating a variation of power consumption of a server according to the present application. In the server power consumption change diagram shown in fig. 1, the horizontal axis represents the rotational speed of the server cooling fan, and the vertical axis represents the power consumption of the server. As can be seen from the power consumption variation curve shown in fig. 1, the power consumption curve of the server is generally "V" along with the adjustment of the fan speed, that is, by adjusting the fan speed of the server, a better power consumption of the server meeting the normal operation of the server can be obtained. It can be understood that the power consumption curve shown in the server power consumption change diagram shown in fig. 1 of the present application is a power consumption change curve obtained by adjusting the rotation speed of the cooling fan under the condition that a plurality of factors such as the operating environment temperature and the operating load of the server are not changed, and the purpose is to illustrate the effect of the present invention. In the actual control process, the environmental temperature and the operation load are constantly changed, so that the rational state shown in fig. 1 cannot be obtained; however, with the technical solution of the present application, it is because of the continuous change of these influencing factors that the dynamic adjustment scheme provided by the technical solution of the present application has the advantage of continuously adapting to the changing situation.

In the field, a server is understood as a kind of computer, where the server provides computing or application services for other clients (e.g., PCs) in a network, and the server itself has high-speed CPU computing capability, long-time running capability, powerful I/O external data throughput capability, and good scalability. Generally, the server has the functions of bearing corresponding service requests and guaranteeing service quality after being started.

In the process of starting or operating the server, the rotating speed of the cooling fan may stay at any position on the horizontal axis in fig. 1, and the position is unknown.

Please refer to fig. 2, which is a flowchart illustrating a method for adjusting server power consumption in real time according to a first embodiment of the present application, specifically, the method performs the following steps of adjusting a fan for cooling a server during the operation of the server:

step S201, based on the current fan speed, adjusting the fan speed in the current adjustment direction by a predetermined step length.

In the first embodiment of the present application, the current adjustment direction refers to increasing the fan speed or decreasing the fan speed to adjust the fan speed, that is, gradually increasing or decreasing the fan speed according to a predetermined step.

The method aims to ensure that the server is always in a normal running state on the premise of reducing the running power consumption of the server. The reduction of the power consumption of the server is mainly realized by adjusting the rotating speed of the cooling fan, namely, the overall power consumption of the server is reduced by adjusting the operating temperature of various electronic devices of the server. It can be understood that, in the process of adjusting the rotating speed of the cooling fan, it is also required to ensure that each operating condition of the server meets the preset operating standard. The operation standard mainly means that the operation temperature of each electronic device of the server is in a preset temperature range.

The preset temperature range is an early warning temperature value. In the actual operation process of the server, the operating temperature may be higher than the preset temperature due to a higher operating load of the server or a higher ambient temperature, but the normal operation of the server is not affected if the operating temperature of the server exceeds the preset temperature range in a short time, but at this time, the operating state of the server may be at a critical point that is about to crash. In response to this situation, the operating temperature of each electronic device in the server needs to be adjusted by adjusting the rotation speed of the cooling fan to meet the preset temperature. In a specific application process, in the process of adjusting the operating temperature of the server to be within a preset temperature range, the adjustment of the rotating speed of the cooling fan is realized by adopting a PID control algorithm or other common control algorithms in the field. Specifically, in the process of adjusting the operating temperature of the server to be within the preset temperature range, the adjustment of the rotating speed of the cooling fan includes the following steps S201-1 to S201-4:

step S201-1, obtaining the temperature of each device of the server.

The temperature of each device of the server refers to the operating temperature of each electronic device in the server, and can be obtained through a temperature sensor built in the device.

Step S201-2, judging whether the temperature of each device of the server is in a preset temperature range.

And step S201-3, if the judgment result is negative, adjusting the rotating speed of the fan for cooling the server by a preset temperature adjusting scheme until the temperature of each device meets a preset temperature range.

And step S201-4, if the judgment result is yes, the step of adjusting the rotating speed of the fan to the current adjusting direction by the preset step length is carried out.

The preset temperature adjusting scheme is that the rotating speed of the fan is adjusted based on a PID control algorithm or other common control algorithms built in the server, so that the temperature of each device of the server is within a preset range. Since the built-in PID control algorithm or other common control algorithms of the server are in the prior art, and this part is not within the scope of the present application. Therefore, the embodiment of the present application does not describe the above process of adjusting the fan rotation speed based on the PID algorithm and other common control algorithms built in the server to keep the operating temperature of each device of the server within the preset temperature range.

Under the condition that the operation temperature of each electronic device in the server is ensured to be within the preset temperature range, the method for adjusting the power consumption of the server in real time provided by the embodiment of the application is implemented, so that the overall power consumption of the server is ensured to be always in a lower state.

In addition, in an alternative embodiment of the present application, the current fan speed in step S201 may be an initial speed when the server starts up, that is, in a case where the server starts up, the speed of the cooling fan is initialized, and then step S201 of the present application is executed.

Specifically, when the server is started, the initialization of the rotational speed of the cooling fan includes the following steps S201-a and S201-b.

Step S201-a, when the server is started, according to the operating environment temperature of the server, obtaining a first rotating speed of the fan capable of meeting the starting requirement of the server.

Wherein the first rotational speed is a cooling fan rotational speed for initializing a fan rotational speed.

Step S201-b, initializing the first rotating speed as the current fan rotating speed.

In step S201-b, the current fan speed obtained by initialization is the critical fan speed for normal server startup.

Specifically, the obtaining a first rotation speed of the fan capable of meeting the server start-up requirement according to the operating environment temperature of the server includes:

obtaining a second rotating speed which can enable the fan to be started normally; obtaining a third rotating speed of the fan capable of meeting the operation requirement of the server according to the operation environment temperature of the server; and selecting the higher one of the second rotating speed and the third rotating speed as the first rotating speed of the fan capable of meeting the starting requirement of the server.

The second rotating speed capable of enabling the fan to be normally started is the critical rotating speed for starting the fan, and the corresponding third rotating speed of the fan meeting the operation requirement of the server is the critical rotating speed for normally starting the server. That is, of the threshold rotational speed at which the fan can be started and the threshold rotational speed at which the normal start of the server can be satisfied, the larger one is selected as the first rotational speed.

In step S201, the predetermined step size may be understood as an amount of change of the fan speed each time the fan speed is adjusted, and in an alternative embodiment of the present application, the predetermined step size is 1%, that is, the fan speed is adjusted by 1% each time. For example, if the current fan speed is 500r/min, the fan speed is 505r/min or 495r/min after step S201 is executed. Of course, the step size can also be set to a fixed rotational speed value, for example 5 r/min.

In the process of adjusting the rotating speed of the fan in real time, the preset step length can be adjusted according to a preset step length adjusting strategy; the preset step size adjustment strategy can have various selectable schemes, and specific modes are detailed later.

It can be understood that the method for adjusting the rotating speed of the fan is performed in real time, and in the process of running the server, factors influencing the power consumption of the server, such as the running load of the server, the running environment temperature and the like, are all uncontrollable factors which change constantly. After the fan speed is adjusted, since the server itself is in an operating state, and in order to ensure a normal operating state of the server, the fan speed may also be changed due to a temperature change during a next adjustment period. Therefore, in an alternative embodiment of the present application, it is also necessary to collect the fan speed and adjust the fan speed according to a preset time interval. The collection of the fan rotating speed can be realized based on a fan rotating speed collecting unit arranged in the server.

In the embodiment of the application, the current rotating speed of the cooling fan of the server can be realized by a fan rotating speed acquisition unit arranged in the server. For the adjustment of the rotating speed of the fan, the voltage at two ends of the coil of the fan motor can be controlled through Pulse Width Modulation (PWM), and the adjustment is realized by changing the voltage. The principle of PWM pulse width modulation is as follows:

please refer to fig. 3, which is a schematic diagram illustrating voltage equivalence in a PWM pulse width modulation process according to a first embodiment of the present application. That is to say, in the process of powering on the fan motor, the PWM generated by the single chip microcomputer continuously controls the open/close state of the fan Field Effect Transistor (FET), so that the coil of the fan motor is repeatedly powered on or powered off, the longer the time of each power on, the larger the equivalent voltage at the two ends of the coil of the fan motor, the larger the generated magnetic field strength, the faster the motor rotor rotates (i.e. the faster the fan speed), and conversely, the slower the fan speed.

And step S202, comparing the power consumption data of the server before and after the adjustment of the fan rotating speed.

In order to ensure the normal operation of the server, the server includes devices such as a memory, a CPU processor, an internal bus, and a power supply. In the first embodiment of the present application, the power consumption data of the server refers to the total power consumption of each device in the server, including the power consumption of the cooling fan itself and the power consumption of each electronic device in the server.

In the first embodiment of the present application, the collection of the power consumption data of the server and the speed regulation of the cooling fan are performed almost simultaneously. For example, assuming that the adjustment process of the cooling fan is performed according to a preset adjustment period, the collection of the server power consumption data may also be performed according to a collection period that is the same as the adjustment period. The server power consumption data may also be acquired after the cooling fan is adjusted in speed, for example, after the fan speed acquisition unit for acquiring the rotational speed of the cooling fan determines that the rotational speed of the fan changes, an acquisition instruction is sent to the device for acquiring the server power consumption, so that the server acquisition device acquires the server power consumption data.

Specifically, the power consumption data of the server is obtained through a BMC (Baseboard management Controller) inside the server system, where the BMC is an independent subsystem in the server and may interact with a signal transmission system and an operating system in the server to manage the temperature, the power supply, and the like of the entire server. Please refer to fig. 4, which is a schematic diagram of a BMC subsystem interaction structure according to a first embodiment of the present application.

Fig. 4 includes: the system comprises a BMC chip 401, an I/O chip 402, a network interface controller 403, a serial interface connector 404, a switch logic controller 405 and an intelligent platform controller 406 which are deployed in the server.

The BMC chip 401 manages each element by obtaining data generated by each element. In the first embodiment of the present application, the BMC chip 401 mainly obtains the power consumption data of each of the above elements, and further determines the total power consumption data of the server.

It is to be understood that the connection relationship between the BMC chip 401 and each element and the data transmission relationship according to fig. 4 are only for facilitating understanding of the present application. In other embodiments, the BMC chip 401 may also obtain power consumption data of other elements in the server system, which is not limited in this application.

In the process of adjusting the power consumption of the server by adjusting the fan speed, the position of the fan speed in fig. 1 is unknown. Therefore, it is unknown whether the method of increasing the rotation speed of the fan in predetermined steps provided in step S201 of the first embodiment of the present application can reduce the power consumption of the server, it is unknown whether the power consumption data of the server has reached the extreme point shown in fig. 1, and it is also position whether the power consumption data of the server can be continuously reduced in such a manner that the rotation speed of the cooling fan is continuously adjusted in the current adjustment direction. Therefore, after the rotation speed of the fan is adjusted each time, the power consumption data before and after the adjustment of the rotation speed of the fan needs to be compared.

Step S203, if the power consumption data after the fan rotating speed is adjusted is smaller than the power consumption data before the fan rotating speed is adjusted, the adjusted fan rotating speed is set as the current fan rotating speed, and the step of adjusting the fan rotating speed in the current adjusting direction by the preset step length is returned.

If the power consumption data after the adjustment of the rotating speed of the fan is smaller than the power consumption data before the adjustment, the current adjustment direction is correct. Please refer to fig. 5a, which is a first distribution diagram of the server power consumption when the power consumption data after the adjustment of the fan speed is smaller than the adjusted fan speed according to the first embodiment of the present application. That is, assuming that the power consumption data after the fan speed adjustment is W2, the power consumption data before the fan speed adjustment is W1, and W2 < W1, it means that if the fan speed continues to be increased at predetermined time intervals, the power consumption of the server continues to be reduced for a while until it falls to a desired extreme point. In this case, therefore, the step of returning to the adjustment of the fan rotation speed in the current adjustment direction by a predetermined step size is continuously performed. Until the power consumption before the adjustment of the rotating speed of the fan is smaller than the power consumption data after the adjustment. Step S204 is then performed. In an optional implementation manner of the present application, if it is reasonable to always adjust the rotation speed of the fan according to the current adjustment direction, and after the rotation speed of the fan is adjusted for multiple times, a situation occurs in which the power consumption before the adjustment of the rotation speed of the fan is greater than the power consumption data after the adjustment. The preset step length can be further adjusted to be one half of the original preset step length according to a preset step length adjusting strategy, and the rotating speed of the fan is further adjusted according to the reverse direction opposite to the current adjusting direction until the condition that the power consumption before the rotating speed of the fan is adjusted is smaller than the adjusted power consumption data occurs again. So that the adjusted power consumption of the server is closer to the minimum value of the power consumption.

To facilitate understanding of the above-mentioned process of adjusting the predetermined step size to be one-half of the original predetermined step size and further adjusting the rotation speed of the fan according to the reverse direction opposite to the current adjustment direction. Please refer to fig. 5b, which is a diagram illustrating a second distribution of power consumption of a server according to the first embodiment of the present application.

If it is reasonable to adjust the fan speed in the current adjustment direction, if the power consumption W1 before the adjustment of the fan speed is less than the adjusted power consumption data W2, which means that there is a high possibility that the minimum value of the power consumption of the server exists between the power consumption W1 and the power consumption W2, then further adjusting the fan speed in the opposite direction by one third of the predetermined step size on the basis of the corresponding fan speed when the power consumption of the server is W2 would be that the power consumption of the server is further close to the minimum value of the power consumption of the server, so that the server can operate with better power consumption.

Step S204, if the power consumption data after the adjustment of the fan rotating speed is larger than the power consumption data before the adjustment, the adjusted fan rotating speed is set as the current rotating speed, the current adjustment direction is updated to be the direction opposite to the original current adjustment direction, and then the step of adjusting the fan rotating speed in the current adjustment direction by the preset step length is returned.

If the power consumption data after the adjustment of the fan rotation speed is greater than the power consumption data before the adjustment, it means that the current adjustment direction is wrong, please refer to fig. 5c, which is a third distribution diagram of the power consumption of the server provided in the first embodiment of the present application. That is, assuming that the power consumption data after the fan speed adjustment is W2, the power consumption data before the fan speed adjustment is W1, and W1 < W2, the power consumption of the server continues to increase if the fan speed continues to be increased at predetermined time intervals.

At this time, the adjustment direction of the fan rotation speed needs to be adjusted and updated immediately, so that the updated adjustment direction of the current fan rotation speed is opposite to the original current adjustment direction. And then adjusting the rotating speed of the fan according to the current adjusting direction by a preset step length.

As described in the above embodiments, the predetermined step adjustment strategy may take a variety of forms; the above-mentioned general use of equal step length, when the adjustment direction conversion occurs, it is a feasible adjustment strategy to reduce the step length by a certain proportion; in addition, other adjustment strategies may also be employed.

For example, a fixed step adjustment strategy may be used entirely, the fixed step being a fixed rotational speed, or a fixed proportion of the current rotational speed, for example 10% or 5%. Under the strategy, the control strategy is simpler.

Alternatively, in step S202, in the step of comparing the power consumption data of the server before and after the adjustment of the fan speed, an appropriate step size may be set according to the comparison result; for example, a corresponding table of the difference value of the power consumption data before and after adjustment and the step length is established, in the table, the smaller the difference value of the power consumption data before and after adjustment, the smaller the corresponding step length, and the specific corresponding relationship can be determined according to an experiment or theoretical model; in step S203 and step S204, the step length is set according to the correspondence relationship, and the process returns to step S201.

In order to facilitate understanding of the method for adjusting the power consumption of the server provided by the present application, the method for adjusting the power consumption of the server provided by the present application in real time is described below with reference to fig. 6a and 6 b. Fig. 6a and fig. 6b are two different real-time adjustment methods for server power consumption according to a second embodiment of the present application, respectively.

Fig. 6a is a first method for adjusting power consumption of a server in real time according to a second embodiment of the present application. The method comprises the following steps S601 a-S614 a.

In step S601a, the server system is started.

The starting of the server system is to start the server system. It is understood that the step S601a can also be understood as a case where the server system is operating normally.

Step S602a, determining in real time whether the operating temperature of each electronic device of the server is lower than a preset temperature.

In the process of executing the method for adjusting the power consumption of the server in real time, it is necessary to ensure that each electronic device of the server is in a normal operating state in real time.

If the determination result of determining whether the operating temperature of each electronic device of the server is lower than the preset temperature is no, step S603a is further performed.

In step S603a, the rotation speed of the cooling fan is adjusted by a PID control algorithm or other control algorithms built in the server. Until the operating temperature of each electronic device in the server is within a preset temperature range.

If the judgment result of judging whether the operating temperature of each electronic device of the server is lower than the preset temperature is no, determining that the server is in a normal operating state, and proceeding to step S604.

In step S604a, the current rotation speed of the cooling fan S1 and the current average power consumption W1 of the server system are obtained.

The current rotation speed S1 of the cooling fan is the rotation speed corresponding to the cooling fan during the execution of the method for adjusting the power consumption of the server. While acquiring the current rotating speed S1 of the cooling fan, determining power consumption data W1 corresponding to the server, wherein the power consumption data comprises: the power consumption of the cooling fan itself and the average power consumption W1 of the other electronics in the server. After determining the current rotation speed of the cooling fan S1 and the current average power consumption W1 of the server, the flow proceeds to step S605 a.

In step S605a, the rotation speed of the cooling fan is increased by a predetermined step size S1, where the rotation speed of the cooling fan after the increase is set to S2, and S2 is S1+ S1 × 1%.

The predetermined step size is a change amount of the fan rotation speed each time the fan rotation speed is adjusted, and in the second embodiment of the present application, the predetermined step size is 1%, and the rotation speed of the fan is adjusted by 1% each time. When the rotating speed of the fan is increased, power consumption data corresponding to the server after the rotating speed of the fan is increased also needs to be recorded.

In step S606a, average power consumption data W2 of the system after the cooling fan speed is increased is recorded.

The average power consumption W2 recorded in step S606a is the average power consumption corresponding to the system after the rotation speed of the cooling fan is increased. After the above-described steps S602a and S603a are performed, a step S607a of power consumption determination is performed.

In step S607a, it is determined whether the power consumption data W2 after the cooling fan speed is raised is smaller than the power consumption data W1 before the raising.

If the power consumption data of the cooling fan after the rotating speed of the cooling fan is increased W2 is smaller than the power consumption data before the rotating speed of the cooling fan is increased W1, the fact that the rotating speed of the cooling fan is increased on the basis of the current rotating speed S1 is shown to reduce the average power consumption of the system. In this case, step S608a is performed.

In step S608a, the current fan speed S1 is recorded as S2, the current average power consumption W1 is recorded as W2, and the process returns to step S605 a.

And repeating the steps until the power consumption data W2 after the rotating speed of the cooling fan is increased is larger than the power consumption data W1 before the rotating speed is increased, and completing the rotating speed increasing small-cycle process.

In the process of adjusting the fan speed to reduce the power consumption of the server through the above steps S605a to S608a, the power consumption of the server may suddenly change due to the change of the server load and the operating environment temperature, for example: in the process of sudden increase of the server load, the operation power consumption of the server is inevitably correspondingly increased. In the method for adjusting the power consumption of the server in real time provided by the embodiment of the application, no matter the condition that the power consumption data after the rotating speed of the fan is increased is larger than the power consumption data before the rotating speed of the fan is increased due to the change of the operating environment of the server; or simply the situation that the power consumption data after the fan rotating speed is increased is larger than the power consumption data before the fan rotating speed is increased due to the change of the fan rotating speed. Upon occurrence of the above, the flow proceeds to step S609 a.

In step S609a, the current fan speed S1 is recorded as S2, and the current average power consumption W1 of the system is recorded as W2.

The purpose of step S609a is to update the rotation speed and average power consumption of the cooling fan, so as to execute the step of rotating speed reduction small cycle. After the above step S609a is performed, step S610a is performed.

Step S610a is executed to decrease the rotation speed of the cooling fan S1 by a predetermined step size, where the decreased rotation speed of the cooling fan is set to S3, and S3 is S1-S1 × 1%.

In step S610a, the predetermined step is the same as the step in step S605a, and is 1% of the current fan speed S1. After the above step S610a is executed, the process proceeds to step S611 a.

In step S611a, the average power consumption W3 of the system after the cooling fan speed is reduced is recorded.

The average power consumption W3 recorded in step S611a is the average power consumption corresponding to the system after the rotation speed of the cooling fan is reduced. After the above-described steps S610a and S611a are performed, a step S612a of power consumption determination is performed.

In step S612a, it is determined whether the power consumption data W3 after the cooling fan rotation speed is reduced is smaller than the power consumption data W1 before the reduction.

If the power consumption data W3 after the cooling fan speed is reduced is smaller than the power consumption data W1 before the cooling fan speed is reduced, it is shown that the average power consumption of the server system can be reduced by reducing the fan speed on the basis of the current speed S1. In this case, step S613a is executed.

In step S613a, the current fan speed S1 is adjusted to S3, the current average power consumption W1 of the system is adjusted to W3, and the process returns to step S610 a.

This is repeated until the power consumption data W3 after the reduction of the rotational speed of the cooling fan becomes larger than the power consumption data W1 before the reduction, and the process of the rotational speed reduction small cycle is completed.

In step S612a, if the power consumption data W3 after the cooling fan rotation speed is reduced is larger than the power consumption data W1 before the reduction, it is indicated that a further change in the rotation speed adjustment direction is required. And proceeds to step S614 a.

In step S614a, the current fan speed S1 is adjusted to S3, the current average power consumption W1 is adjusted to W3, and the process returns to step S604 a.

The purpose of step S614a is to update the current rotation speed and the average power consumption of the cooling fan, so as to re-enter the rotation speed increasing small cycle step to complete the rotation speed adjusting large cycle.

In fig. 6b, the process of adjusting the rotation speed is substantially the same as the steps S601a to S613a, that is, after the server system is started, the rotation speed reduction loop is executed first when the operating temperature of the server is determined to meet the preset temperature; entering a rotating speed increasing small cycle under the condition that the power consumption data after the rotating speed is reduced is larger than the power consumption data before the rotating speed is reduced; and returning to the rotation speed small cycle under the condition that the power consumption data after the rotation speed is increased is larger than the power consumption data before the rotation speed is increased, and further completing the rotation speed large cycle.
