An embodiment of the present application provides a method for controlling a fan rotation speed, where the method may be applied to a distributed network, where the distributed network may include a plurality of nodes (e.g., servers, etc.), the method may be applied to any node of the distributed network, where this node is referred to as a local node, and other nodes of the distributed network are associated nodes of the local node, as shown in fig. 1, which is a flowchart of the method, and the method may include:

And 102, determining the reference environment temperature of the node according to the real environment temperature of the associated node.
In one example, if the real ambient temperature of the local node is not obtained from a sensor (e.g., a temperature sensor) of the local node, the reference ambient temperature of the local node may be determined according to the real ambient temperature of the associated node. Alternatively, if the real environment temperature of the local node is obtained from a sensor (e.g., a temperature sensor) of the local node, the reference environment temperature of the local node may also be determined according to the real environment temperature of the associated node.
In another example, if the real environment temperature of the local node is not obtained from the sensor of the local node, the reference environment temperature of the local node may be determined according to the real environment temperature of the associated node. Or, if the real environment temperature of the node is obtained from the sensor of the node, the reference environment temperature of the node does not need to be determined according to the real environment temperature of the associated node, but the fan speed of the node is controlled according to the real environment temperature of the node, and a second temperature notification message is sent to the associated node of the node, where the second temperature notification message may carry the real environment temperature of the node.

Alternatively, one associated node may be selected from the plurality of associated nodes according to the position information and the temperature change trend of the local node and the position information and the temperature change trend of the associated node, and the selected associated node may be used as the target node.
Of course, the above-described manner is merely an example, and is not limited thereto. For example, if the number of associated nodes is one, the associated node may be used as a target node. Alternatively, if the number of associated nodes is plural, one associated node may be randomly selected from the plural associated nodes, and the selected associated node may be used as the target node.
Wherein, according to the position information of the node and the position information of the associated node, selecting an associated node from a plurality of associated nodes comprises: according to the position information of the local node and the position information of the associated nodes (such as the position information of each associated node), the distance between the local node and the associated nodes (such as the distance between the local node and each associated node) is determined, and one associated node is selected from a plurality of associated nodes according to the distance.

Furthermore, the temperature difference of the target node can be determined according to the real environment temperature of the target node at the first moment and the real environment temperature of the target node at the second moment; and determining the reference environment temperature of the node at the second moment according to the temperature difference of the target node and the real environment temperature of the node at the first moment.
And 103, controlling the fan rotating speed of the node according to the reference environment temperature of the node.
In an example, the execution sequence is only an example given for convenience of description, and in practical applications, the execution sequence between steps may also be changed, and the execution sequence is not limited. In other embodiments, the steps of the corresponding methods are not necessarily performed in the order shown and described herein, and the methods may include more or less steps than those described herein.

Based on the same application concept as the method described above, an embodiment of the present application further provides another method for controlling a fan rotation speed, where the method may be applied to any node of a distributed network, and this node may be referred to as the present node, and as shown in fig. 2, the method is a flowchart of the method, and the method may include:
Specifically, one associated node may be selected from the multiple associated nodes according to the location information of the node and the location information of the associated node, and the selected associated node may be used as the target node; or, one associated node may be selected from the plurality of associated nodes according to the temperature variation trend of the node and the temperature variation trend of the associated node, and the selected associated node is used as the target node; alternatively, one associated node may be selected from the plurality of associated nodes according to the location information and the temperature change trend of the local node and the location information and the temperature change trend of the associated node, and the selected associated node may be used as the target node.
And step 204, controlling the fan rotating speed of the node at the second moment according to the reference environment temperature of the node at the second moment. For example, the higher the reference ambient temperature, the higher the fan speed may be.
In an example, the execution sequence is only an example given for convenience of description, and in practical applications, the execution sequence between steps may also be changed, and the execution sequence is not limited. In other embodiments, the steps of the respective methods are not necessarily performed in the order shown and described herein, and the methods may include more or less steps than those described herein. Moreover, a single step described in this specification may be broken down into multiple steps for description in other embodiments; multiple steps described in this specification may be combined into a single step in other embodiments.
Based on the technical scheme, in the embodiment of the application, in the operation process of the node, the real environment temperature of the associated node (namely, the peripheral node) of the node can be continuously learned, the reference environment temperature of the node is determined by using the real environment temperature of the associated node, and the fan rotating speed of the node is controlled according to the reference environment temperature of the node.
Based on the same application concept as the method, an embodiment of the present application further provides a method for controlling a fan rotation speed, which may be applied to any node of a distributed network, where this node may be referred to as the present node, and the method may include: and acquiring the real environment temperature of the node from the sensor of the node, and controlling the fan rotating speed of the node according to the real environment temperature of the node. Further, a second temperature notification message is sent to the associated node of the node, and the second temperature notification message carries the real environment temperature of the node, so that the associated node controls the fan rotating speed of the associated node according to the real environment temperature carried by the second temperature notification message.
The above technical solution is explained below with reference to specific application scenarios. Referring to fig. 3, a networking schematic diagram of the application scenario is shown, a distributed network may include 4 nodes (such as a server, a terminal device, a network device, and the like, and the type of the node is not limited), and of course, the distributed network may also include other number of nodes, which is not limited in this regard. Further, the nodes may be connected through a switch 340.
Node 300 may include a BMC301 and a sensor 302 (e.g., a temperature sensor for sensing an ambient temperature), where sensor 302 may provide the ambient temperature to BMC301 and BMC301 may adjust a fan speed of node 300 according to the ambient temperature. Similarly, node 310 may include a BMC311 and a sensor 312, where sensor 312 may provide an ambient temperature to BMC311, and BMC311 may adjust a fan speed of node 310 based on the ambient temperature. The node 320 may include a BMC321 and a sensor 322, and the sensor 322 may provide an ambient temperature to the BMC321, and the BMC321 may adjust a fan speed of the node 320 based on the ambient temperature. The node 330 may include a BMC331 and a sensor 332, where the sensor 332 may provide an ambient temperature to the BMC331, and the BMC331 may adjust the fan speed of the node 330 based on the ambient temperature.
For the sake of convenience of distinction, the ambient temperature sensed by each sensor may be referred to as the real ambient temperature.
In the application scenario, referring to fig. 4, the method for controlling the rotation speed of the fan may include:
in step 401, bmc301 determines whether the real ambient temperature of node 300 is obtained from sensor 302.
If yes, the BMC301 executes step 402; if not, BMC301 proceeds to step 404.
Wherein, BMC301 may periodically determine whether to obtain the real ambient temperature of node 300 from sensor 302; after steps 402 and 403, it is possible to wait until the next cycle and re-execute step 401; after steps 404 and 405, it may wait until the next period to re-execute step 401.
In step 402, BMC301 sends LLDP message to other BMCs (e.g. BMC311, BMC321, BMC331, etc.), which may carry the real environment temperature of node 300.
In step 403, the bmc301 controls the fan speed of the node 300 according to the real ambient temperature of the node 300, and the control method is not limited. For example, the higher the true ambient temperature, the higher the fan speed.
For example, sensor 302 may provide real ambient temperature 11 at time 1 to BMC301, such that BMC301 may obtain real ambient temperature 11 of node 300 from sensor 302 and send an LLDP message to other BMCs, which may carry real ambient temperature 11 at time 1.
Further, the above steps may be performed periodically, for example, the sensor 302 provides the real environment temperature 12 at time 2 to the BMC301, the BMC301 sends an LLDP message carrying the real environment temperature 12 to other BMCs, the sensor 302 provides the real environment temperature 13 at time 3 to the BMC301, the BMC301 sends an LLDP message carrying the real environment temperature 13 to other BMCs, and so on.
In one example, the LLDP message may carry, in addition to the real environment temperature, the location information of the node 300 and the local serial number of the node 300, and the content of the LLDP message is not limited.
With respect to step 403, at time 1, bmc301 obtains real ambient temperature 11 at time 1 from sensor 302, and may control the fan speed of node 300 according to real ambient temperature 11; at time 2, bmc301 obtains real ambient temperature 12 from sensor 302 at time 2 and may control the fan speed of node 300 based on real ambient temperature 12; at time 3, bmc301 obtains real ambient temperature 13 from sensor 302 at time 3 and may control the fan speed of node 300 based on real ambient temperature 13, and so on.
In practical applications, the BMC311 may also send an LLDP message to other BMCs, the BMC321 may also send an LLDP message to other BMCs, and the BMC331 may also send an LLDP message to other BMCs, where a specific processing flow may be similar to that of the BMC301, and details are not repeated here.
In summary, the BMC301 may receive the LLDP message sent by the BMC311 at the time 1, and obtain the real environment temperature 21 of the node 310 at the time 1 from the LLDP message; the LLDP message sent by BMC311 at time 2 may be received, and the real environment temperature 22 of node 310 at time 2 is obtained from the LLDP message; the LLDP message sent by the BMC311 at time 3 may be received, and the real environment temperature 23 of the node 310 at time 3 is obtained from the LLDP message; and so on. In addition, the LLDP message may also carry location information of the node 310 and a local serial number of the node 310, so that the BMC301 may associate the location information with the local serial number and maintain the temperature information table shown in table 1.
TABLE 1
Similarly, the BMC301 may further associate the information of the node 320, the information of the node 330, and the information of the local node (i.e., the node 300), referring to the temperature information table shown in table 2.
TABLE 2
In step 404, bmc301 determines a reference ambient temperature for node 300 based on the real ambient temperature of the associated node (e.g., node 310, node 320, node 330, etc.). For convenience of distinction, the ambient temperature determined according to the real ambient temperature of the associated node may be referred to as a reference ambient temperature.
In step 405, bmc301 controls the fan speed of node 300 based on the reference ambient temperature of node 300, without limitation. For example, the higher the true ambient temperature, the higher the fan speed.
For example, at time 4, BMC301 does not obtain the real ambient temperature at time 4 from sensor 302 (e.g., sensor 302 cannot sense the real ambient temperature of node 300, or sensor 302 cannot provide the sensed real ambient temperature to BMC 301), BMC301 may determine the reference ambient temperature of node 300 according to the real ambient temperature of the associated node, and control the fan speed of node 300 according to the reference ambient temperature of node 300. At time 5, BMC301 does not obtain the real ambient temperature of time 5 from sensor 302, then BMC301 may determine the reference ambient temperature of node 300 from the real ambient temperature of the associated node, and control the fan speed of node 300 based on the reference ambient temperature of node 300, and so on.
In an example, if the BMC301 does not obtain the real ambient temperature of the node 300 from the sensor 302, it may further send, to other BMCs (e.g., the BMC311, the BMC321, the BMC331, and the like), revocation notification information for enabling the other BMCs to prohibit determining the reference ambient temperature of the associated node according to the real ambient temperature of the node 300, that is, when the other BMCs do not obtain the real ambient temperature from the sensor, the reference ambient temperature of the associated node may not be determined by using the real ambient temperature of the node 300.
In an example, if the BMC301 determines the reference ambient temperature of the node 300 according to the real ambient temperature of the associated node, the BMC may send an LLDP message to other BMCs, where the LLDP message carries the reference ambient temperature of the node 300, or may not send the LLDP message to other BMCs, which is not limited to this.
In one example, for step 404, the reference ambient temperature may be determined in a manner including, but not limited to:
in step 4041, bmc301 selects an associated node from the associated nodes as a target node.
Specifically, if the number of the associated nodes is one, the BMC301 takes the associated node as a target node. Alternatively, if the number of associated nodes is multiple, the BMC301 may select one associated node from the multiple associated nodes, and use the selected associated node as the target node. For example, the BMC301 may randomly select one associated node from the plurality of associated nodes, or select one associated node from the plurality of associated nodes using a policy, which is described below.
In the first mode, the BMC301 selects an associated node from a plurality of associated nodes according to the location information of the node 300 and the location information of each associated node (e.g., the node 310, the node 320, and the node 330), and uses the selected associated node as a target node. Specifically, the BMC301 may determine a distance between the node 300 and each associated node according to the location information of the node 300 and the location information of each associated node, and select one associated node from the plurality of associated nodes according to the distance, for example, select the associated node with the smallest distance.
For example, node 300 is located at slot 1 of the cabinet, node 310 is located at slot 2 of the cabinet, node 320 is located at slot 3 of the cabinet, and node 330 is located at slot 4 of the cabinet. Based on this, the distance between the node 300 and the node 310 is 1, which means that the node 300 and the node 310 are adjacent nodes of the cabinet; the distance between the node 300 and the node 320 is 2, which means that the node 300 is separated from the node 320 by one node; the distance between node 300 and node 330 is 3, indicating that two nodes are spaced between node 300 and node 330. In summary, the node 310 may be selected from a plurality of associated nodes according to the distance, i.e., the node 310 is the target node.
In the second mode, the BMC301 selects one associated node from the plurality of associated nodes according to the temperature change trend of the node 300 and the temperature change trend of each associated node, and uses the selected associated node as a target node. Specifically, the BMC301 may determine a deviation parameter between the node 300 and each associated node according to the temperature variation trend of the node 300 and the temperature variation trend of each associated node, and select one associated node from a plurality of associated nodes according to the deviation parameter, for example, select the associated node with the smallest deviation parameter.
For example, based on the real environment temperature 11 of the node 300 at the time 1, the real environment temperature 12 at the time 2, and the real environment temperature 13 at the time 3, the temperature variation trend of the node 300 may be determined. If the temperature variation trend is a slope, a straight line can be obtained by using the real environment temperature 11 and the real environment temperature 12, and the slope A1 of the straight line is determined; a straight line can be obtained by using the real environment temperature 12 and the real environment temperature 13, and the slope A2 of the straight line is determined, and so on. Assuming that the temperature variation tendency is a temperature difference, a temperature difference 1 between the real environment temperature 11 and the real environment temperature 12 is calculated, a temperature difference 2 between the real environment temperature 12 and the real environment temperature 13 is calculated, and so on. Similarly, based on the real environment temperature 21 of the node 310 at the time 1, the real environment temperature 22 at the time 2, and the real environment temperature 23 at the time 3, the temperature variation trend of the node 310 may be determined. Based on the real environment temperature 31 of the node 320 at the time 1, the real environment temperature 32 at the time 2, and the real environment temperature 33 at the time 3, the temperature variation trend of the node 320 can be determined. Based on the real ambient temperature 41 of the node 330 at time 1, the real ambient temperature 42 at time 2, and the real ambient temperature 43 at time 3, the temperature trend of the node 330 can be determined.
Assuming that the temperature variation trend is a slope, if a target node at time 3 is selected, determining a deviation parameter 1 of the node 300 and the node 310 according to a slope A1 of the node 300 and a slope B1 of the node 310 (determined based on the real environment temperature 21 and the real environment temperature 22), wherein the deviation parameter 1 is a difference value between the slope A1 and the slope B1; determining a deviation parameter 2 of the node 300 and the node 320 according to the slope A1 of the node 300 and the slope C1 of the node 320; determining a deviation parameter 3 of the node 300 and the node 330 according to the slope A1 of the node 300 and the slope D1 of the node 330; assuming that the deviation parameter 1 is minimal, node 310 is selected as the target node. If the target node at time 4 is selected, determining deviation parameters of the node 300 and the node 310 according to the slope A2 of the node 300 and the slope B2 of the node 310 (determined based on the real environment temperature 22 and the real environment temperature 23); determining deviation parameters of the node 300 and the node 320 according to the slope A2 of the node 300 and the slope C2 of the node 320; determining deviation parameters of the node 300 and the node 330 according to the slope A3 of the node 300 and the slope D3 of the node 330; and then selecting the node corresponding to the minimum deviation parameter as a target node.
Assuming that the temperature variation trend is a temperature difference, determining a deviation parameter of the node 300 and the node 310 according to the temperature difference of the node 300 and the temperature difference of the node 310, wherein the deviation parameter 1 is a difference value between the temperature difference of the node 300 and the temperature difference of the node 310; determining deviation parameters of the node 300 and the node 320 according to the temperature difference of the node 300 and the temperature difference of the node 320; determining deviation parameters of the node 300 and the node 330 according to the temperature difference of the node 300 and the temperature difference of the node 330; then, the node corresponding to the minimum deviation parameter is selected as the target node, for example, the BMC301 may select the node 310 as the target node.
In a third mode, the BMC301 selects one associated node from the plurality of associated nodes according to the location information and the temperature change trend of the node 300 and the location information and the temperature change trend of each associated node, and takes the selected associated node as a target node. Specifically, the BMC301 may determine a distance between the node 300 and each associated node according to the location information of the node 300 and the location information of each associated node, determine a deviation parameter between the node 300 and each associated node according to the temperature variation trend of the node 300 and the temperature variation trend of each associated node, and then select one associated node from the plurality of associated nodes according to the distance between the node 300 and each associated node and the deviation parameter between the node 300 and each associated node, for example, after weighting the distance and the deviation parameter, take the associated node with the smallest weighted value as the target node.
For example, the weighted values of nodes 300 and 310 are a × d1+ B × w1, the weighted values of nodes 300 and 320 are a × d2+ B × w3, and the weighted values of nodes 300 and 330 are a × d3+ B × w3; wherein d1 is the distance between the node 300 and the node 310, and the specific determination manner is referred to as a first manner, and w1 is the deviation parameter between the node 300 and the node 310, and the specific determination manner is referred to as a second manner; d2 is the distance between the node 300 and the node 320, and w2 is the deviation parameter between the node 300 and the node 320; d3 is the distance between node 300 and node 330, w3 is the deviation parameter between node 300 and node 330; in addition, a and B are weighting coefficients, which can be configured empirically, such as a is 0.5, B is 0.5, or a is 0.3, B is 0.7, etc., without limitation.
After the weighted values of the nodes 300 and 310, the weighted values of the nodes 300 and 320, and the weighted values of the nodes 300 and 320 are obtained, the associated node with the smallest weighted value can be used as the target node. For example, assuming that the weighted values of node 300 and node 310 are the smallest, node 310 is taken as the target node.
In step 4042, bmc301 determines the reference ambient temperature of node 300 based on the actual ambient temperature of the target node, i.e., instead of reading the actual ambient temperature from the sensor, a reference ambient temperature is obtained.
For example, the reference ambient temperature of the node 300 at the second time may be determined according to the real ambient temperature of the target node at the first time and the real ambient temperature of the node 300 at the second time, and the real ambient temperature of the node 300 at the first time. Specifically, the temperature difference of the target node may be determined according to the real environment temperature of the target node at the first time and the real environment temperature of the target node at the second time; and determining the reference environment temperature of the node 300 at the second moment according to the temperature difference of the target node and the real environment temperature of the node 300 at the first moment.
For example, if the BMC301 needs to determine the reference ambient temperature of the node 300 at the time 4 and knows the real ambient temperature 13 of the node 300 at the time 3, the BMC301 may obtain the real ambient temperature 23 of the node 310 (i.e., the target node) at the time 3 and the real ambient temperature 24 of the node 310 at the time 4, and then the BMC301 determines the temperature difference a between the real ambient temperature 23 and the real ambient temperature 24 and determines the sum of the real ambient temperature 13 and the temperature difference a as the reference ambient temperature of the node 300 at the time 4.
For another example, if the BMC301 needs to determine the reference ambient temperature of the node 300 at the time 5 and knows the real ambient temperature 13 of the node 300 at the time 3, the BMC301 may obtain the real ambient temperature 23 of the node 310 (i.e., the target node) at the time 3 and the real ambient temperature 25 of the node 310 at the time 5, and then the BMC301 determines the temperature difference B between the real ambient temperature 23 and the real ambient temperature 25, and determines the sum of the real ambient temperature 13 and the temperature difference B as the reference ambient temperature of the node 300 at the time 5.
