Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without any creative effort belong to the protection scope of the present application.
The application of the intelligent network card is more and more extensive under the new development trend of the server industry at present, because the service scene of the application of the intelligent network card and the traditional network card is different, the application mode is also different, and the heat dissipation mode of the traditional server can not meet the application of the intelligent network card, and the intelligent network card is required to be modified and upgraded. After the traditional server enters a standby state, because the heat dissipation of the fan is also the main power supply function of the power supply device in the server, the main power supply is closed after the server is shut down, and the fan of the server is also closed. The intelligent network card often needs to continue to work under high load due to business requirements, and the intelligent network card has large power consumption and large heat dissipation and cannot meet natural heat dissipation. The temperature of the intelligent network card will rise up to 72 degrees centigrade according to the actual test in the laboratory. This also becomes a problem for the server engineer to wait to solve.
The core of the application is to provide a method, a device, a system and a medium for radiating the intelligent network card of the server, which are used for realizing effective radiating of the intelligent network card in a standby state of the server and avoiding equipment damage.
In order that those skilled in the art will better understand the disclosure, the following detailed description will be given with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a flowchart of a heat dissipation method for an intelligent network card of a server according to an embodiment of the present application, where the heat dissipation method includes:
s10: acquiring a trigger signal for representing shutdown of the server.
S11: and controlling the main power supply to be closed.
In one embodiment, the worker may generate a trigger signal requesting the server to be powered on or off by pressing a rear-mounted switch device located at the rear end of the server cabinet. The baseboard management controller can provide a server system state monitoring function, obtain the working state of the server in real time, and control the main power supply to be turned off when obtaining the trigger signal for representing the shutdown of the server. At this time, the basic units in the server, such as the CPU, the hard disk, and the memory, stop operating.
It should be noted that the power supply device in the server includes an onboard switch, a main power supply and an auxiliary power supply, when the server is started, the substrate management controller controls the main power supply to be turned on through the onboard switch to supply power for the normal operation of the server, generally 12V or 48V; when the server is shut down, the baseboard management controller controls the main power supply to be turned off through the onboard switch. When the AC input of the server is connected, the auxiliary power supply outputs power for a long time and supplies the power to units needing long-term power consumption, such as a baseboard management controller and an intelligent network card. It should be noted that the main power supply and the auxiliary power supply in the present application are not two power supplies, but two outputs of the same power supply device.
S12: and after the main power supply is turned off, the fan carrier plate and the auxiliary power supply are switched on.
In specific implementation, after the baseboard management controller controls the main power supply to be turned off, the intelligent network card continues to keep running, the fan support plate and the auxiliary power supply are switched on at the moment, and the fan supplies power through the auxiliary power supply to provide a heat dissipation function for the intelligent network card. It can be understood that, in order to reduce power consumption, in other embodiments, after the main power supply is turned off, the connection between the ventilation fan carrier plate and the auxiliary power supply may also be delayed, and when the heat of the smart card is gathered to a certain degree and the fan needs to be turned on to dissipate heat, the power may be supplied to the fan carrier plate.
It should be noted that, the design idea of the present application is to switch the main power supply or the auxiliary power supply to supply power to the fan by setting a certain power supply switching module, so that the fan can dissipate heat for the intelligent network card in any working state of the server, and especially when the server is in a standby state, normal heat dissipation of the intelligent network card can be ensured, so as to avoid equipment damage.
In this embodiment, the connection mode between the fan carrier and the auxiliary power supply is not limited, in other words, the power supply switching module capable of implementing the above function may be arbitrarily selected. In practical application, the eFuse unit with a better control effect can be adopted, and the eFuse unit can also be realized by a circuit structure which is composed of a first switch tube connected with the main power supply and the fan carrier plate respectively and a second switch tube connected with the auxiliary power supply and the fan carrier plate respectively, and correspondingly, the switch tubes can adopt field effect transistors or insulated gate bipolar transistors. Of course, as a preferred embodiment, the fan carrier board can also be controlled to be connected with the auxiliary power supply directly by the baseboard management controller.
According to the method for radiating the intelligent network card of the server, after the trigger signal for representing shutdown of the server is obtained, the main power supply is controlled to be closed, the server enters a standby state, then the auxiliary power supply is controlled to be connected with the fan support plate, so that the fan is started to radiate the intelligent network card, effective radiation of the intelligent network card in the standby state of the server is achieved, equipment damage is avoided, product quality of the server is improved, and use experience of a user is further improved.
In the server, a plurality of fans are generally arranged on a fan carrier plate, a plurality of intelligent network cards are also arranged on a network card carrier plate, and the fans and the intelligent network cards are not in one-to-one correspondence, so that when the rotating speed of the fans is controlled, the fans nearby are generally started to operate according to the positions of the intelligent network cards. In order to reduce power consumption, a fan far away from the position of the intelligent network card does not need to be started. Fig. 2 is a flowchart of another method for dissipating heat of an intelligent network card of a server according to an embodiment of the present application. As shown in fig. 2, in order to better control the operation of the fan, on the basis of the above embodiment, the method further includes:
s20: a first correspondence of temperature and fan speed is established.
The first correspondence relationship between the temperature and the fan rotation speed may be established after S12, or may be established in advance. If the first corresponding relationship is established after the fan carrier plate and the auxiliary power supply are switched on, the adjusting speed is influenced, and the heat dissipation is not timely. Therefore, in a specific implementation, the above correspondence relationship is generally established in advance, the first correspondence relationship between the temperature and the fan rotation speed can be obtained through experimental data, the first correspondence relationship can be stored in a storage device built in the server, or can be stored in an external storage device, and when the baseboard management controller needs to control the fan rotation speed, the first correspondence relationship is called from the storage device.
It should be noted that the temperature here may be an ambient temperature or a temperature inside the intelligent network card, and may also be a temperature on the intelligent network card carrier plate, and it can be understood that, due to the structural characteristics inside the intelligent network card, the temperature may not be timely transmitted to the environment, and therefore, the actual effect of the ambient temperature is not ideal compared with the temperature inside the intelligent network card and the temperature on the intelligent network card carrier plate. And because the intelligent network card is directly connected with the intelligent network card carrier plate, the temperature difference is not very large, and therefore, the selection can be carried out according to the actual situation.
S21: and acquiring the temperature of the intelligent network card.
In this embodiment, the temperature sensor is disposed on the support plate of the intelligent network card to detect the temperature of the intelligent network card, wherein, in order to obtain a better monitoring effect, the temperature sensor is disposed at the connection between the intelligent network card and the support plate of the intelligent network card, and the substrate management controller senses the temperature information of the intelligent network card by monitoring the temperature sensor, so that it can be understood that the temperature sensor disposed inside the intelligent network card can also be directly detected by the substrate management controller. Baseboard management controller and temperature sensor pass through I2And C, bus connection. The number of the temperature sensors is not limited, the temperature sensors can be in one-to-one correspondence with the intelligent network cards, namely, the temperature sensors are arranged when the intelligent network cards are provided, and the temperature sensors larger than or smaller than the number of the intelligent network cards can also be arranged.
It should be noted that, in the running process of the intelligent network card, the substrate management controller may acquire the values of all the temperature sensors on the intelligent network card carrier plate once every a period of time (for example, 2 seconds), or may continuously acquire the values, which is not limited in this application. In addition, the baseboard management controller knows the current rotating speed of each fan by detecting the TACH signal of each fan to form closed-loop management, and each fan can be independently controlled.
S22: and adjusting the rotating speed of the fan matched with the temperature of the intelligent network card according to the first corresponding relation.
In this embodiment, the substrate management controller adjusts the rotation speed of the fan through the PWM signal, controls the PWM signal to output at a lower duty ratio when the temperature of the intelligent network card is lower, and controls the fan to operate at a lower rotation speed, and controls the PWM signal to output at a higher duty ratio when the temperature of the intelligent network card is higher, and controls the fan to operate at a higher rotation speed.
It should be noted that, after the fan rotation speed matched with the temperature of the intelligent network card is adjusted, the temperature of the intelligent network card may be further obtained, so as to determine the temperature decrease trend of the intelligent network card, if the temperature of the intelligent network card decreases, the fan rotation speed may be correspondingly decreased or the fan rotation may be stopped, and if the temperature of the intelligent network card does not decrease or increases, the fan rotation speed continues to be increased. The specific obtaining mode can be continuous obtaining or obtaining at intervals, and it can be understood that if continuous obtaining is performed, the power consumption of the baseboard management controller is increased, but the timeliness and the accuracy of the fan speed adjustment are improved, so that different obtaining strategies can be adopted according to different application scenes.
Specifically, if the time interval is obtained, the obtaining strategy may be to delay different times according to the intervals of different temperatures, or may also be to delay different times according to the intervals of different fan rotation speeds.
Further, S22 specifically includes:
if the temperature of the intelligent network card is lower than the first temperature, controlling the fan to stop rotating;
if the temperature of the intelligent network card is higher than the first temperature and lower than the second temperature, controlling the fan to rotate at a first rotating speed;
if the temperature of the intelligent network card is higher than the second temperature and lower than the third temperature, controlling the fan to rotate at a second rotating speed;
if the temperature of the intelligent network card is higher than the third temperature, controlling the fan to rotate at a third rotating speed;
the first temperature is lower than the second temperature and lower than the third temperature, and the first rotating speed is lower than the second rotating speed and lower than the third rotating speed.
In this embodiment, a plurality of temperature ranges are set, and each temperature range corresponds to a different fan speed. When the temperature of the intelligent network card is lower than the first temperature (because the environment temperature is generally 20-25 ℃, the first temperature is set to be 35 ℃, but not limited to the value), the temperature of the intelligent network card is low at the moment, heat dissipation is not needed, in order to save energy, the duty ratio of the PWM signal is controlled to be zero, and the fan stops rotating. When the temperature of the intelligent network card is higher than the first temperature and lower than a second temperature (the second temperature can be set according to actual conditions, and is set to be 45 ℃ in this case), the duty ratio of the PWM signal output is controlled to enable the fan to rotate at a first rotating speed (for example, set to be 15%). When the temperature of the intelligent network card is higher than the second temperature and lower than a third temperature (the third temperature can be set according to actual conditions, and is set to be 55 ℃), the fan is enabled to rotate at a third rotating speed (for example, set to be 25%) by controlling the duty ratio of the PWM signal output. When the temperature of the intelligent network card is higher than the third temperature, the temperature of the intelligent network card is high at the moment, and the rotating speed of the fan is controlled to be increased to a third rotating speed (for example, set to be 35%) to rotate.
It should be noted that, the present application is not limited to specific setting values of the first temperature, the second temperature, and the third temperature, and if the server is operated outdoors, the setting values may be dynamically adjusted, so that the specific values of the first temperature, the second temperature, and the third temperature may be adaptively reduced in winter, and the specific values of the first temperature, the second temperature, and the third temperature may be adaptively increased in summer. If the server is operated indoors, a relatively stable set value can be set. It can be understood that the specific numerical values of the first rotating speed, the second rotating speed and the third rotating speed are not limited, and the general idea of design is to save resources as much as possible and reduce energy consumption under the condition of ensuring the heat dissipation of the intelligent network card.
On the basis of the above embodiment, as a preferred embodiment, after controlling the fan to rotate at the third rotation speed, the method further includes:
delaying a preset time length, and judging whether the temperature of the intelligent network card is less than a third temperature or not;
if yes, reducing the rotating speed of the fan;
if not, increasing the rotating speed of the fan.
In this embodiment, when the temperature of the smart card has decreased, if the fan is continuously controlled to rotate at the third rotation speed, the power consumption is increased. Based on this, the temperature of the intelligent network card is seen after the preset time is delayed, if the temperature is not reduced or even continuously increased, the duty ratio of the PWM signal is continuously increased to increase the fan speed, and if the temperature is reduced, the fan speed is adaptively reduced.
Because different intelligent network card structures have different heat dissipation conditions, sometimes the heat in the intelligent network card cannot be well transferred to the intelligent network card carrier plate, so that the value of the temperature sensor is lower than a certain temperature threshold value for a long time, but the internal temperature of the actual network card is accumulated very high. Accurate temperature adjustment cannot be realized. On the basis of the above embodiment, the method further includes:
establishing a second corresponding relation among the temperature, the current and the fan rotating speed of the intelligent network card;
in this embodiment, the current sensor is disposed on the carrier of the intelligent network card to detect the current of the intelligent network card, wherein, to obtain a better monitoring effect, the current sensor is disposed at the connection between the intelligent network card and the carrier of the intelligent network card, and the current sensors are in one-to-one correspondence with the intelligent network card, i.e., there are several intelligent network cards and there are several current sensors. The baseboard management controller senses the load information of the intelligent network card by monitoring the current sensor, and the baseboard management controller and the current sensor sense the load information of the intelligent network card through I2And C, bus connection. It should be noted that, in the running process of the intelligent network card, the substrate management controller may acquire the values of all the current sensors on the intelligent network card carrier plate once every a period of time (for example, 2 seconds), or may continuously acquire the values, which is not limited in this application.
S22 is specifically: and adjusting the rotating speed of the fan matched with the temperature and the current of the intelligent network card according to the second corresponding relation.
In this embodiment, under the condition that the temperature of the intelligent network card is greater than the first temperature and less than the second temperature, whether the current of the intelligent network card is less than the first current is judged; if yes, controlling the fan to rotate at a fourth rotating speed; if not, the fan is controlled to rotate at a fifth rotating speed.
It can be understood that, when the temperature of the intelligent network card exceeds the first temperature, and the current corresponding to the intelligent network card is zero at this time, the temperature of the temperature sensor is considered to be the problem that the environment temperature of the whole machine is too high or other intelligent network cards are transmitted, and the fan corresponding to the intelligent network card does not need to be started, so that the energy is saved. And if the current corresponding to the intelligent network card is smaller (smaller than the first current), controlling the fan to rotate at a fourth rotating speed.
Under the condition that the temperature of the intelligent network card is higher than the second temperature and lower than the third temperature, judging whether the current of the intelligent network card is lower than the second current or not; if yes, controlling the fan to rotate at a sixth rotating speed; if not, controlling the fan to rotate at a seventh rotating speed;
the fourth rotating speed is less than the fifth rotating speed, less than the sixth rotating speed, and less than the seventh rotating speed, and the first current is less than the second current.
It should be noted that, the specific setting values of the first current and the second current are not limited, the specific setting values of the fourth rotation speed, the fifth rotation speed, the sixth rotation speed and the seventh rotation speed are not limited, and the general idea of design is to save resources as much as possible and reduce energy consumption under the condition of ensuring the heat dissipation of the intelligent network card.
According to the heat dissipation method for the intelligent network card of the server, different heat dissipation strategies are provided to control the rotating speed of the fan by combining the current and the temperature of the intelligent network card, so that the method is suitable for more application scenes and application equipment, and the user experience is improved.
Fig. 3 is a flowchart of another method for dissipating heat of an intelligent network card of a server according to an embodiment of the present application.
As shown in fig. 3, in order to better control the operation of the fan, on the basis of the above embodiment, the method further includes:
s30: and acquiring the current of the intelligent network card.
S31: and obtaining the current internal temperature of the intelligent network card corresponding to the current of the intelligent network card based on the change relation between the current of the intelligent network card and the internal temperature.
S32: and obtaining the fan rotating speed corresponding to the current internal temperature of the intelligent network card based on the change relation between the internal temperature of the intelligent network card and the rotating speed.
S33: and controlling the fan to rotate by the fan rotating speed corresponding to the current internal temperature of the intelligent network card.
It should be noted that, through laboratory actual measurement, the current of the intelligent network card is positively correlated with the temperature inside the intelligent network card and the rotating speed of the fan, and since the intelligent network card has different services, efficiencies and heat dissipation conditions, the change relationship between the current and the internal temperature is different from the change relationship between the internal temperature and the rotating speed, the actual measurement needs to be performed according to a specific server. It is to be understood that the relationship between the current and the internal temperature of the intelligent network card and the relationship between the internal temperature and the rotational speed of the intelligent network card may be established after S12, or may be established in advance. If the relationship is established after the fan carrier plate and the auxiliary power supply are switched on, the adjusting speed is influenced, and the heat dissipation is not timely. Therefore, in practical implementation, the correspondence relationship is generally established in advance.
In this embodiment, the baseboard management controller may sense the network card load and indirectly sense the heat dissipation of the intelligent network card according to the current of the current sensor, and when the temperature sensor is lower than a certain temperature threshold value for a long time, the baseboard management controller performs fuzzy control according to the actual measured current, the internal temperature of the network card, and the required minimum fan speed. For example, if the ratio in the present design is 0.12, when the bmc detects that the current of the smart card is 1A, it is the optimal rotation speed to control the fan rotation speed to 12%.
When the current of the intelligent network card is lower than 0.5A, the baseboard management controller adopts an indirect operation mode due to the efficiency problem of the fan, namely the fan operates for 10 seconds and stops operating for 10 seconds indirectly. It is understood that the interval duration may be set to other values, which are not limited in the present application.
