Technical Field
The present invention relates to the field of server technologies, and in particular, to a method, a system, a device, and a storage medium for controlling a rotational speed of a server fan.
Background
One or more fans are disposed in the server chassis for heat dissipation, and at present, the fans are usually controlled by using temperature as an indicator, such as a relatively mature PID control strategy. However, since the temperature has inertia, which means that the current state is influenced by the historical state and the input, the corresponding control strategy is executed only after the temperature is changed in the conventional scheme, which is very easy to cause the situation of over-high temperature, and is not beneficial to stabilizing the temperature in the preset range. Especially, most of the existing servers adopt cable design to reduce the risk of PCIE and SAS high-speed signal quality, and cables are required to be connected with a main board and each daughter card, so that the wiring in the servers is complex and difficult, and the heat dissipation condition of the system is influenced, and therefore, the requirement on fan control is higher. Of course, in order to avoid the situation of over-high temperature, the fan is always operated at a higher rotation speed in the other control mode, and although the problem of over-high temperature is solved, the power consumption of the fan is very high.
In summary, how to more accurately control the fan and avoid the over-high temperature in the server chassis is a technical problem that needs to be solved urgently by those skilled in the art at present.

Detailed Description
The core of the invention is to provide a method for controlling the rotating speed of the server fan, which is beneficial to accurately controlling the fan and avoids the problem of overhigh temperature in a server case.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating an implementation of a method for controlling a rotational speed of a server fan according to the present invention, where the method for controlling the rotational speed of the server fan includes the following steps:
step S101: and detecting the current value of a preset position on the board card of the server case.
A plurality of fans may be disposed in the server chassis, and the rotation speed control method provided by the present application may be applied to each fan. It is understood that the preset position corresponding to the fan described in step S101 may be adaptively different for different fans. For example, a fan is disposed in each of the channel a, the channel B, and the channel C of the server chassis, and for the fan of the channel a, for example, the preset position for detecting the current value is the a position, and for the fan of the channel B, the preset position for detecting the current value is the B position. The preset position generally needs to be set and selected according to a specific chassis structure and a specific circuit structure, but it is understood that the preset position should be a position where power at the position has a significant influence on the temperature of a target area, which is a region where a target fan corresponding to the preset position needs to dissipate heat.
When the current value of the preset position on the server case board card is detected, the detection can be carried out in real time or according to a preset detection period.
Step S102: and when the current value is detected to be increased and the change condition of the current value reaches a preset first trigger condition, increasing the rotating speed of the target fan according to a preset first fan control strategy based on the change condition of the current value.
When the current value is detected to be increased and the change situation of the current value reaches the preset first trigger condition, even though the temperature at the current moment may not be increased, the power is increased, and if the rotating speed of the fan is kept unchanged, the temperature is increased, so that the rotating speed of the target fan is increased in advance.
Specifically, the present application may increase the rotation speed of the target fan according to a preset first fan control strategy, and the specific form of the first fan control strategy may be set and adjusted according to actual conditions, but it should be noted that a change of the current value needs to be used as an influencing factor of the rotation speed of the target fan, that is, the change of the current value is an independent variable or one of the independent variables in the first fan control strategy. For example, the first fan control strategy may be expressed as a function V (I)2-I1) Function V (I)2-I1) Needs to be adaptively adjusted according to a specific server configuration, such as V (I)2-I1)＝k1×(I2-I1)+V0. In the formula, V0Indicating the rotational speed, k, at the previous moment1Is a preset parameter. Of course, in practical applications, the first fan control strategy may be in other more accurate and complex forms, so as to adjust the fan rotation speed more accurately.
The preset first trigger condition may also be set and adjusted according to actual situations, for example, considering that the current is usually detected periodically, in an embodiment of the present invention, step S102 may specifically be: and when the current value is detected to be increased and the change rate of the current value is higher than a preset change rate threshold value, increasing the rotating speed of the target fan according to a preset first fan control strategy based on the change rate of the current value.
In this embodiment, the current value detected at the present time may be subtracted from the current value detected at the previous time, and the result may be divided by the detection period to determine the rate of change in the current value. When the change rate of the current value is higher than the preset change rate threshold value, the current value is shown to rise very fast, so the rotating speed of the target fan is increased according to the preset first fan control strategy based on the change rate of the current value.
In addition, it should be noted that, according to the present application, when a change situation of the current value reaches a preset first trigger condition, the rotation speed of the target fan is increased according to a preset first fan control strategy based on the change situation of the current value, where the change situation of the current value may be an amplitude change situation of the current value, may also be a change rate of the current value, may also include both the amplitude change and the change rate, and the first fan control strategy is adaptively adjusted, which does not affect the implementation of the present invention.
In an embodiment of the present invention, the method may further include:
and when the current value is detected to be reduced and the change condition of the current value reaches a preset second trigger condition, reducing the rotating speed of the target fan according to a preset second fan control strategy based on the temperature value.
In the scheme of this application, realize the prediction to the temperature rise through the detection to the current value, and then adjust the fan rotational speed in advance. Considering that the temperature tends to decrease when the current value decreases, according to the logic described above, one way to do this is to reduce the fan speed based on the change in the current value, i.e., to reduce the fan speed in advance before the temperature decreases.
However, in this embodiment of the present application, it is further considered that if the rotation speed of the fan is reduced in advance, the temperature is not easy to be restored to the target value more quickly, and in practical applications, the server power is often increased immediately after being reduced, if the rotation speed of the fan is reduced immediately according to the reduction of the current value, the rotation speed of the fan may need to be increased again after a short time, which is not favorable for stabilizing the temperature of the control cabinet.
Therefore, in this embodiment, when it is detected that the current value decreases and the variation of the current value reaches the preset second trigger condition, the rotation speed of the fan is not directly decreased based on the variation of the current value, but the rotation speed of the target fan is decreased according to the preset second fan control strategy based on the temperature value. That is, in this embodiment, after the current value is decreased, the rotation speed of the fan is not immediately decreased, but the second fan control strategy based on the temperature value may be effective when the temperature value is changed, so as to decrease the rotation speed of the target fan. The specific form of the second fan control strategy may be set and adjusted according to the actual situation, for example, a conventional PID temperature control strategy may be referred to.
In an embodiment of the present invention, the method may further include:
before the system runs, acquiring the air volume of a target position detected by an air flow sensor;
and adjusting the value of one or more parameters in the first fan control strategy according to the air volume.
In this embodiment, considering that there are many cables in the chassis, if the cables are normally assembled, the air volume at the relevant position should be within the normal range before the system operates, and if the air volume does not reach the normal range, specifically, when the acquired air volume is lower than the preset lower limit value of the air volume, a first prompt message indicating that the chassis is poorly wired may be output, which indicates that the wiring is poorly assembled, resulting in an excessively large wind resistance.
In addition, the obtained air volumes are different, which indicates that the cable has different degrees of obstruction to the air flow, so that the temperature can be maintained at the required target temperature more accurately by controlling the fan rotation speed subsequently, in this embodiment, the values of one or more parameters in the first fan control strategy are also adjusted according to the air volumes, that is, in this embodiment, the detected air volume at the target position and the subsequently detected change of the current value are both used as the influence factors when the fan rotation speed is increased.
In addition, when the acquired air volume is higher than the preset air volume upper limit value, second prompt information indicating that the air speed is too high can be output, so that related workers can notice the situation. The control of the fan rotating speed is more accurately carried out in the embodiment, and the fan efficiency is favorably ensured to be in the optimal range, namely the fan rotating speed is not too low to cause too high temperature, and the fan rotating speed is not too high to increase unnecessary energy consumption.
By applying the technical scheme provided by the embodiment of the invention, the temperature in the chassis is considered to be influenced by the running state of the server, specifically, the temperature of the chassis is changed due to the change of the power of the server, and the power can be reflected by the current. Therefore, the rotating speed of the target fan can be increased according to the preset first fan control strategy based on the change situation of the current value, namely, the increase of the temperature is predicted, the rotating speed of the fan is increased in advance, and the adverse conditions such as reduction of the working efficiency of the server and the like caused by the increase of the temperature are avoided.
Therefore, the scheme of the application is favorable for accurately controlling the fan, and the problem of overhigh temperature in the server case is avoided.
