Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In this application, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
Referring to fig. 1, in the existing rack server architecture, when the amount of data that the server 103 needs to process increases, the temperature of the server 103 will gradually rise. In order to control the temperature of the server 103, the controller 101 of the whole cabinet server collects the temperature of the server 103 collected by the temperature sensor 104, the controller 101 obtains a control signal corresponding to the collected temperature of the server 103 and a set temperature according to a preset temperature control strategy, and the controller 101 adjusts the operating state of the heat sink (such as adjusting the rotating speed of the heat sink) according to the control signal so as to achieve the purpose of controlling the temperature.
However, since the temperature is a result of heat accumulation and there is hysteresis in increasing the processed data amount to the temperature, the temperature control of the server is not timely enough by the single closed-loop control method only using the temperature as an input amount in the prior art, and thus the temperature control mode of the operating state of the heat dissipation device 102 is adjusted after the temperature change is detected, so that the temperature change curve of the server 103 generates large oscillation. At this time, the operation state of the heat dissipation device 102 may be continuously adjusted according to the temperature change of the server 103, and the unstable operation state of the heat dissipation device 102 may cause the electric energy waste of the server of the whole cabinet.
Therefore, the operation state of the heat dissipation device is adjusted through the two parameters of the electrical parameter and the temperature of the server, the electrical parameter can timely respond to the change of the data load of the server, namely the temperature change trend, and therefore the operation state of the heat dissipation device can be timely adjusted by combining the electrical parameter, so that the operation state of the heat dissipation device is more stable, the power consumption of the heat dissipation device is further reduced, and the power consumption of the server of the whole cabinet is correspondingly reduced. The method and the system can be applied to the whole cabinet server, or other whole cabinet processing equipment which is designed in a modularized thought and integrates a cabinet, processing equipment, a power supply, heat dissipation, a switch and the like, or a controller of the whole cabinet server. The following detailed description is made with reference to the accompanying drawings.
Referring to fig. 2, a flowchart of a method for controlling an operating state according to embodiment 1 of the present application is shown, where the method includes the following steps:
201: and acquiring the electrical parameters of the servers in the whole cabinet server.
Wherein the electrical parameter of the server is a parameter that responds to a change in server load faster than the temperature of the server. For example, when the amount of data that the server needs to process and/or store increases, the electrical parameter of the server may change faster than the temperature of the server, so that the temperature of the server may be predicted to rise according to the electrical parameter of the server. That is, the electrical parameter can be used to predict the trend of the temperature change. In this embodiment, the electrical parameter of the server may be the current of the server, the power of the server, or other parameter that responds to the change in the load of the server faster than the temperature.
202: and obtaining an electrical parameter calculation value of the server based on the electrical parameter of the server and the preset electrical parameter of the server.
The preset electrical parameter of the server may be a standard value of the electrical parameter and/or an electrical parameter of the server obtained last time. The electrical parameter standard value may be a value corresponding to an electrical parameter of the server under a normal load, and may also be other values, which is not limited in this embodiment.
In this embodiment, one of the selection ways of the preset electrical parameters is: the preset electrical parameter is set as the electrical parameter standard value when the whole cabinet server is just started, so that the heat dissipation device can be adjusted to a proper running state more quickly. When the temperature of the server is adjusted to a specific range, the preset parameter is set to be the electrical parameter of the server obtained last time, and the sensitivity to the load change of the server is improved.
Another way of selecting the preset electrical parameters is as follows: in the first control flow, the preset electrical parameter is set as an electrical parameter standard value, and in each control flow except the first control flow, the preset electrical parameter is set as the electrical parameter of the server obtained last time.
Another selection method of the preset electrical parameters is as follows: the standard value of the electrical parameter is always adopted to save the link of changing the preset electrical parameter, but the calculation of the calculated value of the electrical parameter of the server has deviation.
The calculated value of the electrical parameter in this embodiment may be, but is not limited to: the numerical value reflecting the difference between the electric parameter of the current server and the standard value of the electric parameter, the numerical value reflecting the variation of the electric parameter of the server, the numerical value reflecting the variation trend of the electric parameter of the server and the like. For example, the difference between the electrical parameter of the server and the preset electrical parameter of the server is calculated to obtain an electrical parameter calculation value reflecting the difference between the electrical parameter of the current server and the electrical parameter standard value, and for example, the preset electrical parameter is the electrical parameter of the server obtained last time, and the electrical parameter calculation value reflecting the variation of the electrical parameter of the server is obtained by the difference between the electrical parameter of the current server and the electrical parameter of the server obtained last time.
203: and obtaining the temperature of the servers in the whole cabinet server.
It can be understood that: the temperature of the server may be obtained from a temperature sensor or other device capable of collecting temperature. The temperature sensor may be installed at an air inlet, a CPU, an internal memory, a hard disk, a chip set, or other locations of the server where temperature control is required, the acquired temperature of the server may be one or more temperatures of the server, and when the temperatures of the plurality of locations of the server are acquired, the temperatures of the server may be obtained based on the temperatures of the plurality of locations, for example, the temperatures of the plurality of locations are averaged.
It should be noted that step 203 is not necessarily performed after step 202. For example, step 203 may be performed first, and then step 201 and step 202 may be performed; or step 201 and step 202 may be performed first and then step 203 may be performed; step 203 may also be performed simultaneously with step 201; or step 203 may be performed simultaneously with step 202; none of the above approaches affect the implementation of the method.
204: and generating a control signal based on the calculated value of the electrical parameter of the server, the temperature of the server and the preset temperature of the server.
The preset temperature of the server may be a set temperature standard value and/or a temperature of the server obtained last time. The temperature standard value may be a temperature value corresponding to a server under normal load of the server. In this step, the preset temperature of the server and the acquired temperature of the server may be temperatures at the same location of the server.
In this embodiment, one of the selection ways of the preset temperature is: when the whole cabinet server is just started, the preset temperature is set as the temperature standard value, so that the heat dissipation device can be adjusted to a proper running state more quickly. When the temperature of the server is adjusted to be within a specific range, the preset temperature is set to the temperature at which the server was last acquired.
Another selection mode of the preset temperature is as follows: in the first control flow, the preset temperature is set as a standard value of the temperature, and in each control flow except the first control flow, the preset temperature is set as the temperature of the server acquired last time.
The preset temperature is selected in another way: the standard value of the temperature is always adopted, and the setting is not changed, so that the link of changing the preset temperature is omitted.
The control signal generated in this step is used to control the operating state of the heat dissipation device, and corresponds to the calculated value of the electrical parameter of the server, the temperature of the server, and the preset temperature of the server, and one mode is as follows: the corresponding relationship between the control signal and the calculated value of the electrical parameter of the server, the temperature of the server and the preset temperature of the server may be set, for example, how little the calculated value of the electrical parameter of the server, the temperature of the server and the preset temperature of the server are set, how the corresponding control signal controls the operation state of the heat dissipation device, so as to find out the matched control signal based on the corresponding relationship.
And when the control signal is generated, the calculated value of the electrical parameter of the server, the temperature of the server and the preset temperature of the server are based, and the calculated value of the electrical parameter of the server is obtained through the electrical parameter of the server and the preset electrical parameter, so that the control method of the operating state of the embodiment uses the electrical parameter as an outer ring and uses the temperature as an inner ring, and the operating state is controlled through a double closed loop of the electrical parameter and the temperature, which will be described with reference to the accompanying drawings.
205: and adjusting the running state of the heat dissipation device in the whole cabinet server based on the control signal. Wherein the control signal can adjust the operating state of the heat sink by changing the operating parameter of the heat sink. For example, the current of the heat sink is adjusted based on the control signal, so that the operating state of the heat sink is adjusted by adjusting the current of the heat sink.
According to the technical scheme, the operation state of the heat dissipation device is adjusted through the two parameters of the electric parameter and the temperature of the server, the electric parameter can timely respond to temperature change, and therefore the operation state of the heat dissipation device can be timely adjusted by combining the electric parameter, so that the operation state of the heat dissipation device is more stable, the power consumption of the heat dissipation device is further reduced, and the power consumption of the server of the whole cabinet is correspondingly reduced.
Referring to fig. 3, a flowchart of a method for controlling an operating state according to embodiment 2 of the present application is shown, where the method includes the following steps:
301: and acquiring the electrical parameters of the servers in the whole cabinet server.
302: and obtaining an electrical parameter calculation value of the server based on the electrical parameter of the server and the preset electrical parameter of the server.
303: and obtaining the temperature of the servers in the whole cabinet server.
304: and obtaining a temperature calculation value of the server based on the temperature of the server and the preset temperature of the server.
It can be understood that: the temperature calculation value of the server can be a numerical value reflecting the difference between the current temperature of the server and a temperature standard value; may be a value of a temperature variation of the reaction server; may be a numerical value reflecting a temperature variation tendency of the server, or the like. For example, a temperature calculation value reflecting a difference between the current temperature of the server and a temperature standard value is obtained by performing difference calculation on the temperature of the server and a preset temperature of the server, and for example, the preset temperature is the temperature of the server obtained last time, and a temperature calculation value reflecting a temperature variation of the server is obtained by a difference between the current temperature of the server obtained last time and the temperature of the server obtained last time.
305: and acquiring an operating state matched with the calculated value of the electrical parameter and the calculated value of the temperature based on a preset control strategy.
In this embodiment, one implementation manner of obtaining the running state is as follows: and acquiring the operating states of the heat dissipation device corresponding to the two calculated values from a preset control strategy according to the numerical value of the electrical parameter calculated value and the numerical value of the temperature calculated value. The preset control strategy comprises a plurality of preset control strategies, each control strategy comprises a numerical range of an electric parameter calculation value, a numerical range of a temperature calculation value and an operation state of the heat dissipation device corresponding to the two numerical ranges, so that after the electric parameter calculation value and the temperature calculation value are obtained, the numerical ranges to which the two calculation values belong are determined, and then the operation state corresponding to the numerical ranges to which the two calculation values belong is obtained and serves as the operation state matched with the electric parameter calculation value and the temperature calculation value.
In this embodiment, another implementation manner of obtaining the operation state is as follows: and judging the change conditions of the electrical parameters and the temperature based on the electrical parameter calculated values and the temperature calculated values, and acquiring the running state based on the change conditions. The process is as follows:
obtaining the temperature change condition of the server based on the temperature calculation value of the server; obtaining the electrical parameter change condition of the server based on the electrical parameter calculation value of the server; and taking the current running state of the server as a reference, and acquiring the running state matched with the temperature change condition and the electrical parameter change condition based on a preset control strategy.
The temperature change condition is used for indicating the change condition of the current temperature of the server relative to the preset temperature, such as the change condition comprises the change condition of the current temperature of the server relative to the preset temperature, and the change condition of the current temperature of the server relative to the preset temperature is unchanged, is increased and is decreased. The same electrical parameter variation is used to indicate the variation of the current electrical parameter of the server with respect to the preset electrical parameter, such as the variation being unchanged with respect to the preset electrical parameter, the variation being larger with respect to the preset electrical parameter, and the variation being smaller with respect to the preset electrical parameter. The preset control strategy can adjust the current running state of the server according to the two change conditions, so that the running state of the server is matched with the two change conditions.
306: a control signal corresponding to the acquired operating state is generated.
One form of the control signal may be a Pulse Width Modulation (PWM) signal, and the frequency and duty ratio of the PWM signal are adjusted based on the acquired operating state.
307: and adjusting the running state of the heat dissipation device in the whole cabinet server based on the control signal. For example, the current of the heat sink is adjusted based on the control signal, so that the operation state of the heat sink is adjusted by adjusting the current of the heat sink.
In this embodiment, the heat dissipation device may be a fan, a water-cooling circulation device, or other devices that can be used for cooling. When the heat dissipation device is a fan, the rotating speed of the fan can be adjusted by adjusting the current of the fan through a Pulse Width Modulation (PWM) signal, so that the temperature control effect is achieved. When the heat dissipation device is a water-cooling circulation device, the rotation speed of the water-cooling circulation device can be adjusted by adjusting the current of the water-cooling circulation device through the PWM signal, and the temperature control effect is achieved.
Referring to fig. 4, a flowchart of a method for controlling an operation state when the heat dissipation device is a fan according to embodiment 3 of the present application is shown, where the method includes the following steps:
401: and acquiring the electrical parameters of the servers in the whole cabinet server.
402: and obtaining an electrical parameter calculation value of the server based on the electrical parameter of the server and the preset electrical parameter of the server.
403: and obtaining the temperature of the servers in the whole cabinet server.
404: and obtaining a temperature calculation value of the server based on the temperature of the server and the preset temperature of the server.
Step 404 is similar to step 304 in example 2, and the explanation of step refers to the explanation of step 304 in example 2.
405: and obtaining the temperature change condition of the server based on the temperature calculation value of the server.
In this step, the temperature variation may be a discrete parameter showing a trend of temperature variation.
In one embodiment, when the temperature calculation value is a difference value obtained by subtracting the last acquired temperature from the current temperature of the server, the temperature change trend of the server can be judged according to the sign of the difference value and the value of the difference value, and the temperature change trend can be divided into temperature increase, temperature decrease and temperature invariance.
In another embodiment, when the calculated temperature value is the current temperature change speed, the numerical value of the calculated temperature value reflects the temperature change speed of the server, and the sign of the calculated temperature value indicates whether the temperature is increasing or decreasing. At this time, the temperature variation trend may include three conditions of temperature increase, temperature decrease and temperature invariance; or the temperature variation trend can be further divided into the situations of rapid temperature rise, slow temperature rise, constant temperature, slow temperature fall, rapid temperature fall and the like by combining the numerical value of the temperature calculation value.
406: and obtaining the electrical parameter change condition of the server based on the electrical parameter calculation value of the server. Likewise, the electrical parameter variation may be a discrete parameter representing a variation trend of the electrical parameter.
In one embodiment, when the calculated value of the electrical parameter is the difference value obtained last time after the current electrical parameter of the server is subtracted from the electrical parameter obtained last time, the variation trend of the electrical parameter of the server can be judged according to the sign of the difference value and the value of the difference value, and the variation situation of the electrical parameter can be divided into large variation, small variation and constant variation.
In another embodiment, when the calculated value of the electrical parameter is the current change speed of the electrical parameter, the value of the calculated value of the electrical parameter reflects the change speed of the electrical parameter of the server, and the sign of the calculated value of the electrical parameter indicates whether the electrical parameter is changed to be larger or smaller. At this time, the trend of the electrical parameter variation may include three conditions of increasing the electrical parameter, decreasing the electrical parameter and maintaining the electrical parameter; or the change condition of the electrical parameter can be further divided into the conditions of quick increase of the electrical parameter, slow increase of the electrical parameter, invariance of the electrical parameter, slow decrease of the electrical parameter, quick decrease of the electrical parameter and the like by combining the numerical value of the calculated value of the electrical parameter.
407: and obtaining a rotating speed adjusting strategy of the fan based on the temperature change condition and the electrical parameter change condition.
Wherein the fan speed adjustment strategy is used for indicating one of increasing the speed, decreasing the speed and maintaining the speed on the basis of the current speed.
408: and generating a control signal matched with the rotating speed adjusting strategy of the fan.
409: and adjusting the running state of the fan in the whole cabinet server based on the control signal.
Wherein the control signal can adjust the operating speed of the fan by changing the current of the fan.

Embodiment 6 of the present application provides a storage medium, in which a computer program code is stored, and when the computer program code is executed, the method for controlling an operating state according to any one of embodiments 1 to 3 is implemented.
For ease of understanding, the application of the present application to a complete cabinet server is described below, and the control of the operating state of the heat dissipation device, i.e., the fan, based on the present application is described.
Referring to fig. 9, it shows the architecture of the whole cabinet server, which includes: the system comprises a server, a cabinet Management Unit (RMC), a cabinet Back plate (RBP), a server Tray Back Plate (TBP), a Node Signal Transfer plate (NSTB), a Baseboard Management Controller (BMC), a Fan Back plate (FB), a Fan (Fan), a Power module (PSU), and a Power Supply Unit (PBP).
Wherein, the RMC is connected with the RBP through a two-wire serial (I2C, Inter-Integrated Circuit) bus; the RBP is connected to the Server TBP through an NSTB located inside a Server Tray (Server Tray); BMC is connected to TBP; the fan is connected to the RBP through the FB; the PSU is connected to the PBP via a Power Management Bus (PMBUS), which is connected to the RMC via the PMBUS. The server is located on a server tray (not shown) connected to the TBP. The RMC in the whole cabinet server can monitor temperature, regulate and control the fan, and can also monitor information such as power consumption, voltage, current and the like of the PSU through the PMBUS.
Referring to fig. 10, it shows a schematic diagram of applying the present application to a complete rack server to control the rotation speed of a heat sink with a temperature-current dual closed loop, so as to control the operating state of the heat sink, and its working process is as follows:
(1) the BMC to which the server belongs collects the temperature collected by each temperature sensor, wherein the temperature comprises the temperature of an air inlet, a CPU, a memory, a hard disk, a chip set and the like.
(2) The BMC communicates the collected temperature to the RMC via the I2C bus. While the current output by the PSU (a representation of the server's electrical parameters) is also passed to the RMC via the PMBUS bus.
(3) The RMC obtains a current variation trend based on the current output by the PSU and a preset current. As shown in fig. 5, the current output by the PSU is compared with the preset current to obtain a current difference value showing the current variation trend, and the current difference value is used as the input of the loop of the temperature control.
(4) The RMC obtains a rotating speed adjusting strategy of the fan based on the current change trend (such as the current difference value), the acquired temperature, the preset temperature and the current rotating speed of the fan.
(5) The RMC generates a control signal matched with a rotating speed adjusting strategy of the fan, and the rotating speed of the fan is adjusted based on the control signal. For example, the rotation speed adjustment strategy of the fan is used for indicating one of increasing the rotation speed, decreasing the rotation speed and maintaining the rotation speed on the basis of the current rotation speed, and the rotation speed is adjusted according to the current of the fan, and the current of the fan is related to the frequency and the duty ratio of the signal, so that the embodiment can adjust the frequency and the duty ratio of the PWM signal as the control signal based on the rotation speed adjustment strategy to adjust the fan current based on the frequency and the duty ratio of the PWM signal, and adjust the rotation speed of the fan by adjusting the fan current to realize the heat dissipation. Meanwhile, the RBP also collects the real-time rotating speed information of each fan and transmits the information back to the RMC for processing. The frequency and the duty ratio of the PWM signal are both in direct proportion to the current of the fan.
The rotating speed adjusting strategy can have the following 9 conditions:
1) when the current is not changed and the temperature is not changed, the rotating speed adjusting strategy is to maintain the rotating speed of the fan;
2) when the current is unchanged and the temperature is increased, the rotating speed of the fan is slightly increased according to the rotating speed adjusting strategy according to the temperature change value;
3) when the current is unchanged and the temperature is reduced, the rotating speed of the fan is slightly reduced according to the rotating speed adjusting strategy according to the temperature change value;
4) when the current is increased and the temperature is unchanged, the rotating speed of the fan is quickly increased according to the test experience value, and because the rotating speed of the fan is quickly increased, heat cannot be effectively accumulated, the rotating speed of the fan does not need to be adjusted to the rotating speed of a single closed loop;
5) when the current is increased and the temperature is increased, the rotating speed of the fan is rapidly increased according to the test empirical value, and heat cannot be effectively accumulated, so that the rotating speed of the fan does not need to be adjusted to the rotating speed of a single closed loop;
6) when the current is increased and the temperature is reduced, the rotating speed of the fan is slightly reduced by a rotating speed adjusting strategy;
7) when the current is reduced and the temperature is unchanged, the rotating speed of the fan is reduced by the rotating speed adjusting strategy, and compared with a single closed loop, the rotating speed of the fan is reduced in advance;
8) when the current is reduced and the temperature is increased, the control strategy is to maintain the rotating speed of the fan or slightly increase the rotating speed of the fan according to the temperature change value;
9) when the current becomes small and the temperature is reduced, the control strategy is to rapidly reduce the rotating speed of the fan according to the test empirical value, and the rotating speed of the fan is reduced in advance compared with that of a single closed loop.
The empirical values are values obtained by adjusting the rotation speed of the fan based on the present application, and these values may also vary according to the requirements, and the degree of the minor in the present embodiment is also determined by the practical application, and the present embodiment is not limited.
Based on the above fig. 10, the control of the fan speed is realized by the temperature-current double closed loop, which is the outer loop current closed loop and the inner loop temperature closed loop, the inner loop and the outer loop both adopt the PID control strategy, the output of the outer loop current closed loop is used as the input of the inner loop temperature closed loop, hysteresis of the temperature variable can be suppressed due to the fast responsiveness of the current variable, thus making the control signal of the output of the RMC relatively smooth, and thus the rotation speed of the fan is smoothed to reduce the power consumption of the fan, as shown in fig. 11, which shows a comparison diagram of a single closed loop and a double closed loop, it is obvious from fig. 11 that the current change is relatively stable under the double closed loops, which makes the rotation speed of the fan not change greatly, reduces the power consumption of the fan, and it can also be seen from fig. 11 that the temperature change under the double closed loop is relatively stable, which illustrates that the double closed loop can adjust the temperature change in time.
