In the prior art, a plurality of fans are generally configured in a server, and cooling treatment of the server is completed through cooperative rotation of the fans; when the internal temperature is detected to be too high, the rotating speed of each fan is synchronously increased, and the heat dissipation of the server is accelerated; and when the internal temperature is detected to be lower, the rotating speed of each fan is synchronously reduced so as to save the power consumption of the fan.
However, such a fan control method not only has a large fan power consumption and reduces the service life of each fan, but also cannot realize effective heat dissipation treatment for different components, so that the heat dissipation effect is poor and the heat dissipation efficiency is low.

According to an aspect of the present invention, there is provided a fan rotation speed adjusting method for server operation and maintenance, including:

The obtaining the first regulation value of the associated fan corresponding to the at least one target component includes: and if the temperature change value of the first component in the first preset number of temperature detection periods is greater than or equal to a first change threshold value, or the temperature detection value in the current temperature detection period is greater than or equal to a first temperature threshold value, taking the first component as a target component. Therefore, the component with higher current temperature or the temperature rising trend is used as the target component to be regulated, so that the target component with temperature change is detected in a targeted manner, the number of temperature detection objects is reduced, the fan regulation efficiency is improved, and the reduction of the operation efficiency of the server component caused by temperature rising is avoided.
Before obtaining the first regulation value of the associated fan corresponding to the at least one target component, the method further comprises: acquiring the position relation between each fan and the designated section of each component according to the topological structure of the server; wherein the positional relationship includes a relative distance and a relative angle; and obtaining the fan weight of each component according to the position relation between each fan and the designated section of each component. Therefore, by setting the designated sections for all the components, the components with different packaging modes and different outline structures can be ensured, accurate fan weights can be obtained, the phenomenon that fans with smaller influence on the heat dissipation effect are mismatched into associated fans or fans with larger influence on the heat dissipation effect are mismatched into non-associated fans due to the differences of the packaging modes and the outline structures is avoided, and the accuracy of obtaining the fan regulation values is improved.
After obtaining the fan weight of each component according to the position relation between each fan and each component, the method further comprises the following steps: acquiring a mapping relation between a temperature regulation result and fan power consumption of a current component under the current fan weight; and adjusting the fan weight of the current component, and continuously acquiring the mapping relation between the temperature adjustment result and the fan power consumption of the current component under the current fan weight according to the adjusted fan weight, wherein the fan weight corresponding to the target mapping relation with the minimum fan power consumption in each mapping relation which accords with the expected temperature adjustment result is used as the fan weight of the current component when the adjustment times reach the preset adjustment threshold value. Therefore, the fan weights are continuously adjusted in an iterative mode, the actual cooling effect under each fan weight and the corresponding fan power consumption are obtained, and compared with the theoretical value of the fan weight obtained through the server topological structure, the numerical accuracy of the fan weight is greatly improved for the actual measurement results of the cooling effect and the fan power consumption.
The fan weight corresponding to the target mapping relationship with the minimum fan power consumption in each mapping relationship meeting the expected temperature regulation result is used as the fan weight of the current component, and the method comprises the following steps: respectively taking the fan weights corresponding to the minimum fan power consumption under different temperature detection values as the fan weights of the current component under each temperature detection value; or the fan weight corresponding to the minimum fan power consumption under different temperature change values is respectively used as the fan weight of the current component under each temperature change value. Therefore, one component is respectively provided with different fan weights under different temperature detection values or temperature change values, so that the component can ensure the minimum power consumption of the fan and reduce the rotation loss of the fan while achieving the expected cooling effect.
The fan rotating speed adjusting method for the operation and maintenance of the server comprises the following steps: in response to detecting the abnormal component, acquiring a third regulation value of each fan according to an emergency cooling strategy corresponding to the abnormal component; wherein the temperature change value of the abnormal component in a second preset number of temperature detection periods is greater than or equal to a second change threshold value, or the temperature detection value in the current temperature detection period is greater than or equal to a second temperature threshold value; acquiring a third regulation value of the associated fan corresponding to the non-abnormal part, and acquiring the third regulation value of the non-associated fan corresponding to the non-abnormal part according to the third regulation value of the associated fan corresponding to the non-abnormal part and the fan weight corresponding to the non-abnormal part; and taking the maximum third regulating value corresponding to each fan as a fourth regulating value, and regulating the rotating speed of each fan according to the fourth regulating value. Therefore, the rapid cooling of the abnormal parts is realized, the temperature stability of the non-abnormal parts is maintained, the power consumption of the fan is saved, and the service life of the fan is prolonged.
After adjusting the rotation speed of each fan according to the fourth regulation value, the method further comprises: judging whether the abnormal part has a temperature falling trend or not according to a temperature change curve of the abnormal part in a third preset number of temperature detection periods; and if the abnormal part is determined to have no temperature descending trend, regulating the rotating speed of each fan to be the maximum value. Therefore, the power consumption of the fan is maximally reduced while the continuous cooling of abnormal parts with higher temperature is ensured. Therefore, the power consumption of the fan is maximally reduced while the continuous cooling of abnormal parts with higher temperature is ensured; meanwhile, when the current cooling mode is invalid, each fan is adjusted to the maximum value, and the abnormal part is prevented from being heated up again.

It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein.

Example 1
Fig. 1 is a flowchart of a fan speed adjusting method for operation and maintenance of a server according to an embodiment of the present invention, where the embodiment is applicable to achieving fan speed adjustment by respectively obtaining an associated fan control value and an unassociated fan control value of a target component, and the fan speed adjusting device for operation and maintenance of the server may be implemented in hardware and/or software, and the fan speed adjusting device for operation and maintenance of the server is configured in the server, for example, in a baseboard management controller (Board Management Controller, BMC) of the server. As shown in fig. 1, the method includes:
s101, acquiring a first regulation and control value of an associated fan corresponding to at least one target component.
The server comprises a plurality of components such as a memory, a processor, a hard disk and the like, wherein each component is distributed at different positions of the server, temperature sensors are arranged in the components or nearby the components and used for monitoring temperature information of the corresponding components, and the server acquires the current temperature of the corresponding components by periodically reading the temperature information of each temperature sensor; each component can have the same detection period, namely the server reads the temperature information of all the temperature sensors simultaneously in the current detection period, and the components configured with the temperature sensors are all target components; the different components may correspond to different detection periods, that is, the server may read only the temperature information of a part of the temperature sensors in the current detection period, where the component configured with the temperature sensors and reaching the detection period is the target component.
In order to ensure the heat dissipation effect of the server, a plurality of fans are usually configured in the server, and the fans are equally distributed at different positions of the server, so that the relative positions of the components and the fans are different, and the heat dissipation effect of each fan on the components is also different; if one fan is closer to one component, the influence of the fan on the heat dissipation effect of the component is obvious, and the fan is the associated fan of the component; if one fan is far away from one component, the effect of the fan on the heat dissipation effect of the component is not obvious, and the fan is an unassociated fan of the component; the associated fans and the non-associated fans of each component may be preconfigured. Alternatively, in the embodiment of the present invention, the number of fans, and the types of components and the number of components provided with the temperature sensor are not particularly limited.
One component may correspond to a plurality of associated fans, that is, the influence of the plurality of associated fans on the heat dissipation effect of the component is obvious; meanwhile, one fan can also be used as an associated fan of a plurality of components, namely, the fan has obvious influence on the heat dissipation effect of the plurality of components. The regulation value refers to regulating the rotating speed of the fan, and controlling the fan to reach a specific value, so that the regulation value is also the rotating speed value; particularly, if the fans installed in the server are all fans with the same specification and the same model, the regulation value actually refers to the duty ratio; wherein, the duty ratio refers to the percentage of the current rotating speed and the highest rotating speed; since the maximum rotation speeds of the fans of the same specification and the same model are the same, the control of the rotation speeds can be converted into the control of the duty ratio.
Optionally, in an embodiment of the present invention, the obtaining a first regulation value of an associated fan corresponding to at least one target component includes: and if the temperature change value of the first component in the first preset number of temperature detection periods is greater than or equal to a first change threshold value, or the temperature detection value in the current temperature detection period is greater than or equal to a first temperature threshold value, taking the first component as a target component.
Specifically, if the temperature of a component is low and the temperature remains stable, it is obvious that the component does not have a need to increase the heat dissipation speed, and then the rotation speed of the fan corresponding to the component does not need to be adjusted, so that the target component is actually a component that has a need to increase the heat dissipation speed or decrease the heat dissipation speed; if the current temperature (i.e., the temperature detection value) of a component is high, for example, greater than or equal to the first temperature threshold, it is obviously necessary to increase the heat dissipation speed of the component, i.e., the target component.
Further, if there is a temperature rising trend of one component, for example, a temperature change value at a plurality of (i.e., a first preset number of) temperature detection periods is equal to or greater than a first change threshold value, the target component is regarded as well even if the current temperature thereof is low; wherein, the temperature change value is the temperature difference value between the temperature detection value of the current temperature detection period and the temperature detection value of the corresponding historical temperature detection period; therefore, the component with higher current temperature or the temperature rising trend is used as the target component to be regulated, so that the target component with temperature change is detected in a targeted manner, the number of temperature detection objects is reduced, the fan regulation efficiency is improved, and the reduction of the operation efficiency of the server component caused by temperature rising is avoided.
The first regulation value of the associated fan is a preset regulation value for the corresponding associated fan aiming at the temperature detection value and/or the temperature change value of the target component, and the first regulation value of the matched associated fan can be directly obtained through a preset regulation mapping table according to the temperature detection value and/or the temperature change value of the corresponding target component; the regulation and control mapping table records the temperature detection values and/or temperature change values of different target components and the mapping relation of the temperature detection values and/or temperature change values and the first regulation and control values of the associated fans; for example, when the temperature detection value of the target component a is 50 degrees and the temperature change value is 5 degrees, the first regulation value of the associated fan 1 of the target component a is 60%, that is, the rotational speed of the associated fan A1 is 60% of the maximum rotational speed thereof.
S102, acquiring a first regulation value of a non-associated fan corresponding to the at least one target component according to the first regulation value of the associated fan and the fan weight corresponding to the target component.
The fan weight refers to the proportional relation of the heat dissipation effect of each fan on the component, and reflects the proportion of the heat dissipation effect of different fans on the component in the whole heat dissipation effect of all fans on the component; different parts often have different fan weights according to different relative positions of the parts and the fans; the closer a fan is to the current component, the more obvious it affects the heat dissipation effect of the component, the greater the value of the fan in the fan weight of the component; the farther a fan is from the current component, the less obvious the effect it has on the heat dissipation of the component, and the smaller the value of the fan weight of the fan in the component; the fan weight corresponding to each fan can be pre-configured and recorded in the speed regulation mapping table.
For one component, except for the associated fans, the remaining fans in the server are all unassociated fans; for example, taking a server including 3 fans as an example, the fan weight corresponding to the component a is 3:2:1, that is, the ratio of the fan 1, the fan 2, and the fan 3 is 3:2:1; the duty ratio of the fan 1 is 60% by querying the regulation mapping table, and the duty ratio of the fan 2 and the fan 3 is 40% and 20% by corresponding fan weights.
Optionally, in an embodiment of the present invention, before obtaining the first regulation value of the associated fan corresponding to the at least one target component, the method further includes: acquiring the position relation between each fan and the designated section of each component according to the topological structure of the server; wherein the positional relationship includes a relative distance and a relative angle to a specified component section; and obtaining the fan weight of each component according to the position relation between each fan and each component.
Specifically, in the conventional technical scheme, the distance between the component and the fan directly determines the weight value of each fan, and the closer the distance is, the larger the weight value of the fan is; the farther the distance, the smaller the weight of the fan; however, in reality, the packaging modes of different components are different, so that the outline structure is different, and the association relation between the two components cannot be truly reflected only according to the distance between the two components (for example, the distance between center points).
For example, if the component B is enclosed inside the case and provided with an opening at the front end section thereof, and the fan 1 is located near the rear end face of the component B, even if the relative distance between the fan 1 and the component B is small, the effect of the fan 1 on the heat radiation of the component B is not significant, and therefore, different specified sections can be provided for different components according to the differences in the way of enclosing and the outline structure, and the fan weights of the respective components can be obtained according to the relative distance and the relative angle of the fan and the specified sections of the component.
The smaller the relative distance and the smaller the relative angle between the fan and the designated section of the component, the greater the weight value of the fan; the greater the relative distance and the greater the relative angle of the fan to the designated section of the component, the smaller the weight of the fan; as described in the above technical solution, if the fan 1 faces the rear end section of the component B, the relative angle is 180 degrees, that is, the maximum relative angle; if the fan 1 is facing the front section of the component B, the relative angle is 0 degrees, i.e. the minimum relative angle.
In particular, for an unpackaged component or a component with the same outline structure of each section, all sections can be configured as designated sections, namely, the minimum relative distance and the minimum relative angle between the fan and each section of the component are obtained, and the weight value of the current fan is obtained based on the minimum relative distance and the minimum relative angle; therefore, by setting the designated sections for all the components, the components with different packaging modes and different outline structures can be ensured, accurate fan weights can be obtained, the phenomenon that fans with smaller influence on the heat dissipation effect are mismatched into associated fans or fans with larger influence on the heat dissipation effect are mismatched into non-associated fans due to the differences of the packaging modes and the outline structures is avoided, and the accuracy of obtaining the fan regulation values is improved.
S103, taking the maximum first regulating and controlling value corresponding to each fan as a second regulating and controlling value, and regulating the rotating speed of each fan according to the second regulating and controlling value.
For each target component, as described in the above technical solution, the first regulation and control value of the associated fan is obtained by querying the speed regulation mapping table, and the first regulation and control value of the non-associated fan is obtained by calculating the fan weight; if the number of the target components is only one, each fan only acquires one regulating value (namely a first regulating value), and the regulating value is the maximum regulating value; if the number of the target components is multiple, each fan can acquire multiple regulating values, and the maximum value (namely the maximum first regulating value) in the multiple first regulating values corresponding to the current fan is the actual regulating value (namely the second regulating value), so that the second regulating value is used as the rotating speed value of the current fan, and the rotating speed adjustment of all fans in the current detection period is completed.
According to the technical scheme, a first regulation value of an associated fan corresponding to at least one target component is obtained; acquiring a first regulation value of a non-associated fan corresponding to at least one target component according to the first regulation value of the associated fan and the fan weight corresponding to the target component; and taking the maximum first regulating and controlling value corresponding to each fan as a second regulating and controlling value, and regulating the rotating speed of each fan according to the second regulating and controlling value. The heat dissipation device not only reduces the power consumption of the fan and prolongs the service life of the fan, but also realizes directional heat dissipation for different components, improves the heat dissipation effect of the components, meets the heat dissipation requirements of all the components in the server, and improves the heat dissipation efficiency of the server.
Example two
Fig. 2 is a flowchart of a fan rotation speed adjusting method for operation and maintenance of a server according to a second embodiment of the present invention, and the relationship between the present embodiment and the above embodiments is that, according to a fan weight obtained by a server topology, iterative processing is further required to obtain a fan weight with updated numerical value. As shown in fig. 2, the method includes:
s201, acquiring the position relation between each fan and a designated section of each component according to the topological structure of the server; wherein the positional relationship includes a relative distance and a relative angle.
S202, obtaining the fan weight of each component according to the position relation between each fan and the designated section of each component.
S203, obtaining the mapping relation between the temperature regulation result and the fan power consumption of the current component under the current fan weight.
S204, adjusting the fan weight of the current component, and continuously acquiring the mapping relation between the temperature adjustment result and the fan power consumption of the current component under the current fan weight according to the adjusted fan weight, wherein the fan weight corresponding to the target mapping relation with the minimum fan power consumption in each mapping relation which accords with the expected temperature adjustment result is used as the fan weight of the current component when the adjustment times reach the preset adjustment threshold value.
After obtaining the fan weight of each component according to the topological structure of the server, obtaining the mapping relation between the temperature regulation result and the fan power consumption according to the fan weight; wherein, the temperature adjustment result can comprise a temperature change value and adjustment time consumption; the adjustment time consumption can be represented by the number of detection periods, namely, the adjustment of the temperature change value is completed by how many detection periods; fan power consumption may be expressed by the product of the sum of the rotational speeds of the individual fans and the time taken for adjustment. And then continuously modifying the fan weight of the current component, and obtaining the mapping relation between the temperature regulation result and the fan power consumption after each modification until the adjustment times reach a preset adjustment threshold value.
The expected temperature regulation result is a preset temperature regulation result, and comprises a second change threshold value and a first time consumption threshold value; the expected temperature regulation result is met, namely the temperature change value is larger than or equal to the second change threshold value, and the regulation time consumption is larger than or equal to the first time consumption threshold value; and taking the fan weight in the target mapping relation with the minimum fan power consumption in each mapping relation meeting the expected temperature regulation result as the actual fan weight of the current component, namely the fan weight subjected to iterative training adjustment.
The fan weight obtained under the server topological structure is used as an initial fan weight, and after the initial fan weight is adjusted each time, a temperature regulation result and fan power consumption under the current fan weight are obtained, so that the fan weight is continuously adjusted in an iterative mode, the actual cooling effect under each fan weight and the corresponding fan power consumption are obtained, and compared with the theoretical value of the fan weight obtained through the server topological structure, the actual measurement result of the cooling effect and the fan power consumption is greatly improved in numerical accuracy of the fan weight.
