Disclosure of Invention

The embodiment of the invention provides a method and equipment for adjusting the rotating speed of a fan, and aims to reduce the power consumption of the fan on the equipment.

In a first aspect, an embodiment of the present invention provides a method for adjusting a rotation speed of a fan, where the method is applied to an apparatus provided with the fan, and the method includes:

the equipment acquires service information, wherein the service information is information related to a service executed by the equipment, such as working dynamic parameters of a corresponding device on the equipment when the equipment executes the service, description information of the service type and the like, and then the equipment determines the current service type of the equipment according to the service information and adjusts the rotating speed of the fan according to the current service type. The heat emitted by the equipment may be different because the equipment operates in different service types, so that the rotating speed of the fan on the equipment can be adjusted according to the current service type, wherein the adjustment of the rotating speed of the fan includes controlling the rotating speed of the fan and the starting and stopping of the fan, or only controlling the rotating speed of the fan or controlling the starting and stopping of the fan.

In the scheme of the embodiment of the invention, the rotating speed of the fan of the equipment can be adjusted according to the current service type of the equipment, so that the rotating speed of the fan can meet the heat dissipation requirements of the equipment under different service types, and the rotating speed of the fan can be flexibly controlled because the rotating speed of the fan can be correspondingly changed under different service types, thereby reducing the power consumption of the fan and achieving the requirements of energy conservation and consumption reduction.

With reference to the first aspect, in a first possible implementation manner, the adjusting the rotation speed of the fan according to the current service type specifically includes: the equipment determines a target service utilization rate type corresponding to the current service type, so that the target service utilization rate type of the equipment which mainly generates heat under the current service is determined, the target service utilization rate type is the utilization rate of a preset device, and the service utilization rate types are different due to different devices. Then, the equipment determines the current utilization rate value of the target service utilization rate type, so that the equipment can adjust the rotating speed of the fan to the rotating speed corresponding to the current utilization rate value according to the pre-established corresponding relation between the value of the target service utilization rate type and the rotating speed of the fan. In the corresponding relation between the value of the target service utilization rate type and the fan rotating speed, the heat generated when the equipment runs under the value of the target service utilization rate type is positively correlated with the fan rotating speed.

Therefore, after the service type is determined, the rotating speed of the fan is adjusted according to the utilization rate value of the target service utilization rate type of the main use of the equipment running under the current service type, the specific adjustment mode is the corresponding relation between the value of the target service utilization rate type and the rotating speed of the fan, and in the corresponding relation, the heat generated when the equipment runs under the value of the target service utilization rate type is positively correlated with the rotating speed of the fan, so that the rotating speed of the fan is adjusted to be more fit with the actual heat dissipation condition of the equipment, and the power consumption and the noise generated by the equipment fan are reduced.

With reference to the first possible implementation manner of the first aspect, in a second possible implementation manner, the method further includes: the equipment determines a target device corresponding to the target service utilization rate type, for example, the target device includes devices on the equipment such as a CPU, a memory, and the like, and the utilization rate of the target device is the utilization rate of the target service utilization rate type, so that the target device is a main heat generation source on the equipment and needs to pay attention. The equipment then determines the current configuration type of the target device, and the heat generated by the equipment is possibly different even if the target device is in the same utilization rate value due to different configuration types of the target device, so that the equipment adjusts the rotating speed of the fan according to the current configuration type and the current utilization rate value of the target device. Therefore, the rotating speed of the fan of the equipment is adjusted according to the configuration type of the target device and the current utilization rate value of the target device, and the two factors have influence on the heat production and the power consumption of the target device, so that the method provided by the embodiment of the invention can further ensure the rotating speed adjustment of the fan to be further fit with the heat production condition of the equipment, avoid unnecessary increase of the rotating speed, ensure the heat dissipation requirement of the equipment, achieve the effect of flexibly controlling the rotating speed of the fan, and further reduce the power consumption and the noise generated by the fan.

And after the first rotating speed and the second rotating speed are obtained, the rotating speed of the fan is adjusted by using the maximum rotating speed of the first rotating speed and the second rotating speed. In the corresponding relation between the configuration type of the target device and the rotating speed of the fan, the heat generated when the equipment operates under the configuration type of the target device is positively correlated with the rotating speed of the fan. In the embodiment of the invention, when the equipment runs under a certain service type, the utilization rate value and the configuration type of the corresponding target device with more heat generation have influence on the heat generation of the target device, so that the rotating speed of the fan is influenced.

With reference to the third possible implementation manner of the first aspect, in a fourth possible implementation manner, the adjusting the rotation speed of the fan by using the maximum rotation speed of the first rotation speed and the maximum rotation speed of the second rotation speed specifically includes: and when the first rotating speed and the second rotating speed are both zero, controlling the fan to stop rotating. The method of the embodiment of the invention controls the fan to stop only if the configuration type and the utilization rate value of the target device meet the stop requirement, so that the risk brought to the equipment by the stop of the fan can be reduced. Of course, the device controls the fan to restart whenever one of the stall requirements for the configuration type and usage value is not met.

With reference to the first possible implementation manner of the first aspect, in a fifth possible implementation manner, the determining a target service usage rate type corresponding to a current service type specifically includes: and determining a target service utilization rate type corresponding to the current service type according to the pre-established corresponding relationship between the service type and the service utilization rate type.

With reference to the first possible implementation manner of the first aspect, in a sixth possible implementation manner, the adjusting the rotation speed of the fan to a rotation speed corresponding to the current usage rate value specifically includes: and when the current utilization rate value is smaller than a first utilization rate threshold value corresponding to the target service utilization rate type, controlling the fan to stop rotating. The method is simple, and the safety of the implementation of the method can be ensured as long as the first utilization rate threshold is well determined, for example, is lower than the actual utilization rate value which can be stopped by a preset value.

With reference to the sixth possible implementation manner of the first aspect, in a seventh possible implementation manner, the adjusting the rotation speed of the fan to a rotation speed corresponding to the current usage rate value specifically includes: and when the current utilization rate value is larger than a second utilization rate threshold value corresponding to the target service utilization rate type, controlling the fan to start rotating at a rotating speed corresponding to the current utilization rate value. In the scheme, after the second utilization rate threshold value is determined, the fan is controlled to be started quickly when the equipment cannot meet the heat dissipation requirement, and normal operation of the equipment is guaranteed.

With reference to the first to seventh possible implementation manners of the first aspect, in an eighth possible implementation manner, the service type includes a calculation type, a storage type, and a network switching type, a target service usage type corresponding to the calculation type is a CPU usage, a target service usage type corresponding to the network switching type is a network I/O (Input/Output) data access amount, and a target service usage type corresponding to the storage type is an IOPS (Input/Output operations Per Second) data reading frequency.

Therefore, the equipment only adjusts the rotating speed of the fan needing to adjust the rotating speed, does not adjust other fans, and performs targeted control on the fan, so that the normal operation of the equipment is ensured, and meanwhile, the energy consumption is further reduced.

Detailed Description

The embodiment of the invention provides a method and equipment for adjusting the rotating speed of a fan, which are used for reducing the power consumption of the fan on the equipment.

Fig. 1 is a schematic structural diagram of a server, which can be used to execute the method for adjusting the rotation speed of a fan according to an embodiment of the present invention. As shown in fig. 1, the server 100 may be a blade server, where a first blade and a second blade belong to a first partition, and a third blade and a fourth blade belong to a second partition, where different partitions are located in different air ducts, each blade includes devices such as a CPU101, a memory 102, and a hard disk 103 electrically connected to each other, where some of the devices may be used by different blades, for example, the hard disk may be used by the first to fourth blades in common. The server further includes a fan, and as shown in fig. 1, the server includes first to fourth fans. Wherein the first fan 111 and the second fan 112 belong to a first partition and the third fan 113 and the fourth fan 114 belong to a second partition. When the server is in operation, the devices thereon generate heat, and the rotation of the fan can reduce the heat generated by the server, so that the server 100 can operate normally.

In some embodiments, different services are executed on different blades, and since devices used by different services may be different, corresponding power consumption may also be different. Even if the blades executing the same service have different power consumption due to different utilization rates of the corresponding devices. Thus, the heat generated by blades on the same server may be different, and thus, the rotational speeds of fans on the server corresponding to different blades may be different. The servers in fig. 1 are fans on different air ducts, and the rotating speeds may be different.

On the server shown in fig. 1, the server obtains the service information, determines the current service type of the server according to the service information, and then adjusts the rotation speed of the fan on the server according to the current service type. Therefore, the rotating speed of the fan can be adjusted according to the current service type of the equipment, so that the rotating speed of the fan can meet the heat dissipation requirements of the equipment under different service types, the rotating speed of the fan can be flexibly controlled due to the fact that the rotating speed of the fan can be correspondingly changed under different service types, the power consumption of the fan is reduced, and the requirements for energy conservation and consumption reduction are met.

IT should be understood that fig. 1 is illustrated with a server, but the device for executing the method according to the embodiment of the present invention is not limited to the server, and may also be an IT device such as a notebook computer, a communication network element, and other devices, and this is not particularly limited in the embodiment of the present invention.

FIG. 2 is a flow chart illustrating a method of adjusting fan speed according to an exemplary embodiment. With reference to the schematic device diagram shown in fig. 1 and the above description, taking an angle that a server provided with a fan executes the method provided by the embodiment of the present invention as an example, referring to fig. 2, a flow of the method provided by the embodiment of the present invention includes:

step 201: acquiring service information;

the server acquires the service information, namely the server is powered on, the management unit of the server is powered on, and the server detects the service information on the server, so that the management unit of the server can acquire the service information on the server. The service information is information related to a service executed by the server, for example, a working dynamic parameter of a corresponding device on the server when the server executes the service, description information of a service type, and the like, which is not specifically limited in this embodiment of the present invention.

For example, the management unit obtains the calculated amount and the utilization rate information of the CPU and the memory, for example, the management unit obtains the calculated amount and the utilization rate information through an ME channel of an Intel; or the management unit can acquire the network I/O data access amount, the access frequency and the bandwidth use condition through a channel of the bridge chip; or, the management unit may obtain, through the network card, the data reading frequency, the bandwidth, and other conditions of the network IOPS (english full name: Input/output operations Per Second; chinese name: number of times of read/write operations Per Second). The aforementioned calculation amount and usage rate of the CPU and the memory, network I/O data access amount, access frequency, network IOPS data reading frequency, bandwidth, and the like are service information.

Or, if the service information is the description information of the service type, when the server runs the service software, the server can read the description information of the service type on the service software; or when the server runs the service, the description information of the service type, such as the service name, is obtained from the network, and the description information can describe the service type currently run by the server.

IT should be understood that, in the embodiment of the present invention, the method in the embodiment of the present invention is described with a server, for example, the server may be a blade server, but the device for executing the method in the embodiment of the present invention may also be other devices, for example, an IT device such as a notebook computer, a communication network element, and the like, which is not limited in the embodiment of the present invention specifically.

Step 202: and determining the current service type of the server according to the service information.

The server can determine the service type of the service currently executed by the server according to the service information, wherein the service type includes but is not limited to a calculation type, a storage type, a network switching type and the like.

For example, after the server acquires the usage rates of the CPU and the memory, the server sends the usage rates of the CPU and the memory to the management unit, so that the management unit can determine whether the current service type is the calculation type according to the acquired information, for example, if the management unit determines that the usage rates of the CPU and the memory are greater than preset usage rate threshold values of the CPU and the memory, the management unit determines that the service operated by the current server is the calculation type. Similarly, the management unit can determine whether the current service type is a data transmission or network exchange type according to the acquired access amount, access frequency and bandwidth use condition of the I/O data and through a preset corresponding threshold value; the management unit can judge whether the current service type is a storage type according to the obtained conditions of network IOPS data reading frequency, bandwidth and the like, wherein the storage medium used for storage by the server can be a mechanical hard disk, an SSD (Solid State disk; English full name: Solid State Drives) or other media and the like.

For another example, if the service information acquired by the server is description information of a service type, and the description information of the service type corresponds to the storage type, the management unit determines that the currently running service is the storage type. And the process of determining other service types according to the description information of the service types is similar to the process.

Step 203: and determining a target service utilization rate type corresponding to the current service type according to the pre-established corresponding relationship between the service type and the service utilization rate type.

The service utilization rate type is the utilization rate of corresponding types of devices on the server when the server operates the service. When the server runs different services, the devices which are mainly used are different, and the devices have corresponding utilization rates when in work, the devices which are mainly used are main generation sources of the power consumption of the server under the current service, so that the heat which is currently generated by the server mainly comes from the devices, and the utilization rates of the devices on the server need to be detected to determine the rotating speed which is needed by the corresponding fan because the utilization rates of the devices correspond to the heat generated by the devices. The utilization rate of the devices corresponding to the service type currently operated by the server is the target service utilization rate type. Of course, sometimes other devices of the server also work to generate heat, but these other devices generate less heat when executing the current service type, and have little influence on the normal operation of the server, so that the usage rate of these other devices can be ignored, that is, when the server runs a certain service type, the usage rate of the device generating heat smaller than the preset value does not belong to the target service usage rate type.

Because different service types have corresponding service utilization rate types, after the server determines the current service type, the server determines a target service utilization rate type corresponding to the current service type so as to detect the utilization rate value of the target service utilization rate type.

In the embodiment of the invention, the method for determining the target service utilization rate type is that according to the pre-established corresponding relation between the service type and the service utilization rate type, after the service type of the current service of the server is determined, the server determines the target service utilization rate type corresponding to the current service type. The pre-established corresponding relation between the service type and the service utilization rate type is stored in a server, and the corresponding relation can be manually matched and determined according to experiment numerical values and then input to the server so as to enable the server to store the corresponding relation. Or the server may generate the data according to preset rules.

For example, as shown in table one, table one is an example of a correspondence relationship between a service type and a service usage rate type. When the server executes the calculation type service, the CPU of the server consumes more power, and at this time, the CPU is a main source of heat generated by the server, so that the target service utilization rate type corresponding to the calculation type is the CPU utilization rate, and other devices, such as a memory, may also generate a certain amount of heat due to operation, but the generated heat has less influence on the operation of the server, so that the utilization rates of the devices with less influence can be ignored, and the execution process of the method of the embodiment of the present invention is simplified. Similarly, the target service usage type corresponding to the network exchange type is a network I/O data access amount, and the target service usage type corresponding to the storage type is an IOPS data reading frequency.

Table one:

type of service	Type of service usage
		Type of computation	CPU utilization
Network switching type	Network I/O data access volume
		Storage type	IOPS data read frequency

Because the server uses many devices, the service utilization rate types can be various, including but not limited to the utilization rates of a CPU, a memory, a hard disk, a Raid (Redundant Array of Independent Disks; chinese name: Redundant Array of Independent Disks) card, a PCIE card, a network card, and the like.

It can be understood that there may be other methods for determining the target service usage rate type corresponding to the current service type, and this is not limited in this embodiment of the present invention. For example, after the service information is acquired, the management unit determines the current service type of the server according to the service information, and then determines a target service utilization rate type corresponding to the current service type according to the service information, for example, the server detects the utilization rate of the CPU, so that the acquired service information is the CPU utilization rate, and sends the CPU utilization rate to the management unit, and if the management unit determines that the utilization rate of the CPU is greater than a preset utilization rate threshold value of the CPU, the management unit determines that the service type operated by the current server is the calculation type. And the server determines the target service utilization rate type as the CPU utilization rate according to the service information, wherein the CPU utilization rate corresponds to the calculation type.

Step 204: determining a current utilization rate value of the target service utilization rate type;

after determining the target service usage type corresponding to the current service type, the server determines a current usage value of the target service usage type, where the usage value has a plurality of expressions, for example, a percentage of full usage. The specific method for obtaining the current usage rate value of the target service usage rate type may be that the server performs detection through a detection tool thereon, or calls a corresponding instruction, and obtains the corresponding usage rate value after executing the instruction, which is not specifically limited in the embodiment of the present invention.

For example, the target service usage type of the server is CPU usage, and the CPU usage information can be obtained using corresponding tools and commands in the server. As shown in fig. 3 and 4, fig. 3 is a schematic diagram of the obtained current CPU utilization value, and fig. 4 is a schematic diagram of the obtained CPU utilization value at the corresponding time, where in fig. 4, the abscissa is a time unit, and the ordinate is the CPU utilization value.

Step 205: and adjusting the rotating speed of the fan to be the rotating speed corresponding to the current utilization rate value according to the pre-established corresponding relation between the target service utilization rate type value and the rotating speed of the fan.

After the current utilization rate value of the target service utilization rate type is obtained, the management unit of the server can adjust the rotating speed of the corresponding fan to the rotating speed corresponding to the current utilization rate value according to the pre-established corresponding relation between the value of the target service utilization rate type and the rotating speed of the fan. In the corresponding relationship between the target service usage rate type value and the fan speed, the heat generated when the server operates under the target service usage rate type value is in positive correlation with the fan speed, that is, when the server operates under the target service usage rate type, the larger the heat generated by the server under different usage rate values is, the larger the fan speed is, here, the relationship between the heat value and the fan speed may be a relationship of a continuous function or a relationship of a piecewise function, which is not specifically limited in the embodiment of the present invention. In most cases, when the server operates in the target service usage type, the larger the corresponding usage value is, the larger the power consumption generated by the corresponding device is, and thus the larger the heat generated by the server is, and thus the usage value and the fan speed are in positive correlation.

The corresponding relationship between the target service usage rate type value and the fan speed may be obtained through experiments. For example, in an experiment, a server runs a preset service type, a corresponding target service usage type is at a certain usage numerical value, the rotating speed of a corresponding fan is adjusted, the heat dissipation effect of the server is detected in real time, the minimum or smaller rotating speed of the fan is determined as the target rotating speed under the condition that the heat dissipation effect meets a preset requirement, then the corresponding usage numerical value and the target rotating speed are recorded, a mapping table or a fitting curve can be generated according to the data after multiple groups of data are obtained, and therefore the mapping table or the fitting curve records the corresponding relation between the numerical value of the target service usage type and the rotating speed of the fan, and heat generated when the server runs under the numerical value of the target service usage type is positively correlated with the rotating speed of the fan.

The server adjusts the rotating speed of the fan to be the rotating speed corresponding to the current utilization rate value according to the corresponding relation, so that the server has a heat dissipation effect meeting requirements when running under the current utilization rate value of the target service utilization rate type, and the rotating speed of the fan is correspondingly changed along with the utilization rate value, thereby flexibly controlling the rotating speed of the fan and realizing the effect of reducing the power consumption of the fan on the server. In addition, the noise generated by the fan is reduced due to the reduction of the rotating speed of the fan.

For example, table two shows a mapping table of CPU usage and fan speed, where the fan speed is shown as a percentage of the relative maximum fan speed. When the service type of the server is the calculation type, the server acquires the current numerical value of the CPU utilization rate because the CPU utilization rate corresponds to the calculation type, and determines the fan rotating speed corresponding to the current numerical value of the CPU utilization rate according to the mapping relation, for example, when the CPU utilization rate is 33%, the corresponding fan rotating speed is determined to be 40%. I.e., 40% of the maximum fan speed, thereby adjusting the fan speed to 40% of the maximum fan speed. Therefore, under the rotating speed of the fan, the server can meet the heat dissipation requirement and reduce the power consumption and noise generated by the rotating speed of the fan, thereby achieving the effects of energy conservation and noise reduction.

Watch two

As shown in fig. 5, which shows a fitted curve of the correspondence of the CPU usage value and the fan rotational speed obtained from another experiment.

Because the server has different devices, the service usage rate types are more, and the server can store the corresponding relationship between the numerical value of various target service usage rate types and the fan rotating speed, for example, the corresponding relationship between the numerical value of the network I/O data access amount and the fan rotating speed, and the like.

In some embodiments of the present invention, adjusting the rotation speed of the fan includes controlling the start and stop of the fan, or only controlling the start and stop of the fan, so that the start and stop of the fan can be controlled according to the value after obtaining the value of the target service usage rate type. That is, the corresponding relationship between the value of the target service usage rate type and the fan speed also includes the corresponding relationship between the value of the target service usage rate type and the fan start/stop, or only includes the corresponding relationship between the value of the target service usage rate type and the fan start/stop. For example, when the current usage value is less than a first usage threshold corresponding to the target traffic usage type, the fan is controlled to stall. And/or when the current utilization rate value is larger than a second utilization rate threshold value corresponding to the target service utilization rate type, controlling the fan to start rotating at a rotating speed corresponding to the current utilization rate value. The first usage rate threshold and the second usage rate threshold may be the same or different, and the determination of the first usage rate threshold and the determination of the second usage rate threshold may be determined through experiments. Under the target service utilization rate type, when the utilization rate value is smaller than the first utilization rate value, the heat generated by the device corresponding to the target service utilization rate type is smaller, and if the fan stops rotating, the server can also normally run; when the utilization rate value is larger than the second utilization rate threshold value, the heat generated by the corresponding device is large, and the fan needs to be started at the moment to ensure the normal operation of the server, so that the fan can be controlled to start and stop according to the value of the target service utilization rate type, the unnecessary rotation of the fan is avoided, and the power consumption and the generated noise of the fan are reduced.

It can be understood that, when the server runs different service types, the heat generated by the server will also be different, that is, the heat generated by the server is related to the service type of the server running, and according to the relationship, the rotating speed of the fan can be directly adjusted according to the service type. For example, according to the pre-established correspondence between the service type and the fan rotation speed, the rotation speed of the fan is adjusted to be the rotation speed corresponding to the current service type, and the rotation speed of the fan may be greater than or equal to zero. Wherein, the heat quantity generated by the server under different service types is positively correlated with the fan rotating speed. That is, when the server operates in a service type generating high heat, the rotating speed of the fan is also high, and when the server operates in a service type generating low heat, the rotating speed of the fan is also low.

The corresponding relation can be obtained according to experiments, for example, when the server runs different service types, the rotating speed of the fan is adjusted under the condition that the preset heat dissipation requirement is met, and the smaller rotating speed which can be used by the fan under a certain service type is obtained. Therefore, the rotating speed of the fan can be adjusted according to the current service type of the server, so that the rotating speed of the fan can meet the heat dissipation requirements of equipment under different service types, the rotating speed of the fan can be correspondingly changed under different service types, the rotating speed of the fan is flexibly controlled, the power consumption of the fan is reduced, and the requirements of energy conservation and consumption reduction are met.

In some embodiments of the present invention, the fan speed may be adjusted according to the service type and the usage rate value of the target service usage rate type, and the fan speed may be further controlled according to the configuration type of the target device corresponding to the target service usage rate type.

That is, in an embodiment of the present invention, after the steps 201 to 204 are executed, the method for adjusting the rotation speed of the fan according to the embodiment of the present invention further includes: determining a target device corresponding to the target service utilization rate type; determining a current configuration type of a target device; and adjusting the rotating speed of the fan according to the current configuration type and the current utilization rate value of the target device. The target device corresponds to the target service utilization rate type, that is, the target service utilization rate type is the utilization rate of the target device. The method for determining the configuration type of the target device has various ways, such as detecting configuration information, such as a model number and the like, recorded on the target device by a manufacturer by the server.

The rotating speed of the fan is adjusted according to the current configuration type and the current utilization rate value of the target device, and various implementation modes are provided. For example:

step A1: determining a first rotating speed corresponding to the current utilization rate value according to a pre-established corresponding relation between the value of the target service utilization rate type and the rotating speed of the fan;

step A2: determining a second rotating speed corresponding to the current configuration type of the target device according to a pre-established corresponding relation between the configuration type of the target device and the rotating speed of the fan;

step A3: the rotation speed of the fan is adjusted using the maximum rotation speed of the first rotation speed and the second rotation speed.

The corresponding relation record of the value of the target service utilization rate type and the rotating speed of the fan is that the corresponding rotating speed of the fan can be used under different values of the target service utilization rate type, wherein the heat generated when the server operates under the value of the target service utilization rate type is positively correlated with the rotating speed of the fan. The above contents may be referred to as a correspondence between the value of the target service usage rate type and the fan rotation speed.

The corresponding relation between the configuration type of the target device and the rotating speed of the fan records the corresponding rotating speed which can be used by the fan under different configuration types of the target device. The heat generated by the server running under the configuration type of the target device is positively correlated with the rotating speed of the fan, namely when the server uses a certain configuration type of the target device, the generated heat is large, the rotating speed of the fan is large, and when the server uses another configuration type of the target device, the generated heat is small, and the rotating speed of the fan is small.

The target device corresponds to the target service usage type, that is, the target service usage type is the usage of the target device, for example, if the target service usage type is CPU usage, the corresponding target device is CPU. At this time, the service type currently operated by the server mainly uses the target device, and the target service usage rate type is the usage rate of the target device. Because the configuration types of the target devices are different, the heat dissipation conditions are also different, and the rotating speed of the fan can be correspondingly adjusted, so that the rotating speed of the fan is flexibly controlled, unnecessary overlarge rotating speed of the fan is avoided, the power consumption of the fan is reduced, and the requirements of energy conservation and consumption reduction are met.

For example, in a test process, when a server operates in a certain service type, a corresponding target device is a main heat dissipation source, the target device is fixed to be a determined configuration type, the rotation speed of the fan is continuously changed, a smaller fan rotation speed is determined under the condition that a preset heat dissipation condition is met, so that a set of data of the fan rotation speed and the configuration type of the target device is obtained, after multiple tests, multiple sets of such data are obtained, the corresponding relationship between the configuration type of the target device and the fan rotation speed can be obtained according to the data, and the corresponding relationship can be expressed in the form of a fitting curve or a mapping relationship table. The target device may be a CPU, a memory, a hard disk, or the like, for example, the third table is a correspondence between a CPU model and a fan rotation speed, and the configuration type of the target device at this time is the CPU model. And if the target device is a memory/hard disk, the configuration type is memory/hard disk capacity information. That is, the configuration type information is information related to the heat generation amount of the target device.

Watch III

In some embodiments, the management unit of the server controls the fan to stop when the first rotation speed and the second rotation speed are both zero. That is, the usage value of the target service usage type corresponds to the fan stall, and under the usage value of the target service usage type, even if the fan stalls, the server can still meet the heat dissipation requirement; the configuration type of the target device corresponds to the fan stop, namely, when the target device is the configuration type, the server can still meet the heat dissipation requirement even if the fan stops rotating. When the configuration type and the utilization rate value correspond to the fan stop, the fan is controlled to stop rotating, so that power consumption and noise generated by the fan can be reduced, double determination conditions can be achieved, whether the server meets the stop condition or not can be judged more accurately, and risks caused by the fan stop are reduced.

According to the current configuration type and the current utilization rate value of the target device, the rotating speed of the fan is adjusted, and the implementation mode can also be as follows:

the method comprises the steps of carrying out tests, enabling a server to run under a preset service type, enabling a corresponding target service utilization rate type to be the utilization rate of a target device, determining that the target device is a certain configuration type, then determining the corresponding relation between the utilization rate value of the target service utilization rate type and the rotating speed of a fan, and obtaining the corresponding relation between the utilization rate values of various target service utilization rate types and the rotating speed of the fan by changing the configuration type of the target device, wherein the corresponding relations belong to the same target device and respectively correspond to different configuration types.

Therefore, when the server operates in a certain service type, the corresponding target service utilization rate type and the target device are determined, then, the corresponding relation between the corresponding utilization rate value and the fan rotating speed is obtained according to the configuration type of the target device, and according to the corresponding relation between the utilization rate value and the fan rotating speed, the management unit of the server can determine the fan rotating speed corresponding to the current utilization rate value of the target service utilization rate type, and the rotating speed of the fan is adjusted accordingly. Therefore, the rotating speed of the fan can be flexibly controlled, unnecessary overlarge rotating speed of the fan is avoided, the power consumption of the fan is reduced, and the requirements for energy conservation and consumption reduction are met.

It can be understood that the fans controlled in the above embodiments are corresponding fans on the server, one fan may be provided on the server, or multiple fans may be provided on the server, when the server is provided with multiple fans, the fans for adjusting the rotation speed of the server may be all fans, or may be corresponding fans, and the corresponding fans refer to fans whose rotation speed needs to be adjusted when the server runs the current service. For example, the server is provided with a plurality of air channels, which need to be speed-regulated in different regions, and the plurality of air channels refer to at least two air channels, wherein each air channel may be provided with a fan, and when the server runs a service, a device corresponding to the current service type is determined, and in some embodiments, the device corresponding to the current service type is the same as the device corresponding to the target service usage rate type. And then, determining the target air channel where the device corresponding to the service type is located. Because the heating of the device on the target air channel is changed, the fan on the air channel needs to be adjusted, and therefore the target fan in the target air channel is determined; when the rotating speed of the fan is adjusted according to the service type, the rotating speed of the target fan on the target air channel can be adjusted, the heat dissipation conditions of devices on other air channels are not changed, and therefore the rotating speeds of the fans of other air channels are not changed. Alternatively, the aforementioned adjusting of the rotation speed of the fan, for example, adjusting the rotation speed of the fan to a rotation speed corresponding to the current usage rate value, adjusting the rotation speed of the fan according to the current configuration type and the current usage rate value of the target device, and the like, all adjust the rotation speed of the target fan of the target air duct. Therefore, the fan regulated by the server is the fan needing to be regulated, and the fan without regulating the rotating speed is not regulated, so that the server meets the heat dissipation requirement, and the power consumption generated by the server fan is further reduced.
