Background
In the past, the fan that the controller corresponds only dispels the heat for this accuse node and corresponding IO card, however, in 4U4 accuse high-end storage product, this accuse fan only for this accuse node and this accuse node correspond the radiating strategy of IO card will face great energy consumption waste and great noise, no longer be applicable to among the brand-new generation high-end storage product.
First, looking at the architecture of the 4U4 high-end storage, a front-to-back view is shown in fig. 1 and 2 below.
As can be seen from the above figures, the controllers are controlled from top to bottom in an A/B/C/D four-way mode, the height of the controllers is 1U, and the areas of the IO cards corresponding to the A/B/C/D four-way control are shown in a front view, wherein each controller corresponds to 7 fans which are arranged transversely. The height of the fan is 1U. The height of the IO single home card (namely the IO small card) is 2U, the IO single home card is connected with a single controller (each controller is connected with 5 IO small cards), and the height of the IO full home card (namely the IO large card) is 4U, and the IO full home card is simultaneously connected with four controllers.
The controller is connected with the IO card in an orthogonal mode, an IO backboard in the middle is omitted, the connector is directly and orthogonally connected with the connector on the controller, an IO small card is simultaneously connected with one controller, and an IO large card is simultaneously connected with four controllers.
It can be understood from the architecture of 4U4 high-end storage that the controller of 1U height is connected with the IO card of 2U height, and the height of this accuse fan is also 1U, so it can only dispel the heat to this accuse IO small card approximate 1/2 area (for example to controller a's fan, it can only aim at IO small card top), and it is obvious, when IO small card work load is big, when its temperature is in heat dissipation bottleneck point, single accuse will receive very big influence to its radiating efficiency, and similarly, the controller is connected with the IO full home card of 4U height, and this accuse fan can only dispel the heat to this accuse IO full home card approximate 1/4 area.

In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.
It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.
According to an aspect of the present invention, an embodiment of the present invention provides a method for controlling a fan of a server, as shown in fig. 3, which may include the steps of:
s1, respectively acquiring the temperatures of a plurality of corresponding reference points by using the first controller and the second controller, and calculating PWM values according to the temperatures;
s2, sending the PWM value corresponding to the first reference point of the plurality of reference points of the first controller to the second controller and sending the PWM value corresponding to the first reference point of the plurality of reference points of the second controller to the first controller;
s3, judging whether the PWM values corresponding to the first reference point of the first controller are all larger than the PWM values corresponding to the multiple reference points of the second controller and judging whether the PWM values corresponding to the first reference point of the second controller are all larger than the PWM values corresponding to the multiple reference points of the first controller;
s4, responding to the fact that the PWM values corresponding to the first reference points of the first controller are all larger than the PWM values corresponding to the multiple reference points of the second controller, and setting the fan rotating speed corresponding to the second controller according to the PWM values corresponding to the first reference points of the first controller; or responding to that the PWM values corresponding to the first reference points of the second controller are all larger than the PWM values corresponding to the multiple reference points of the first controller, and setting the fan rotating speed corresponding to the first controller according to the PWM values corresponding to the first reference points of the second controller.
According to the scheme provided by the invention, the fans corresponding to the controllers are not only limited to radiating the own controller and the IO cards to which the controllers belong, but also needed to perform speed regulation and radiating on the IO cards to which other controllers belong in the area corresponding to the air duct, namely, when the temperature of the first reference point corresponding to the first controller is compared with the temperatures of the multiple reference points corresponding to the second controller and is in a heat radiating bottleneck, the temperature of the first reference point of the first controller participates in the speed regulation of the fan corresponding to the second controller, and similarly, when the temperature of the first reference point corresponding to the second controller is compared with the temperatures of the multiple reference points corresponding to the first controller and is in the heat radiating bottleneck, the temperature of the first reference point of the second controller participates in the speed regulation of the fan corresponding to the first controller.
In some embodiments, in step S1, the first controller and the second controller are used to obtain the temperatures of the corresponding multiple reference points, specifically, the reference point of each controller may be inside the controller, the IO small card, the IO large card, and the IO small card controlled by the IO large card. After the temperature of each reference point is obtained, the temperature of each reference point is obtained through the BMC, for example, and the temperature is converted into a corresponding PWM value according to a preset strategy to adjust the rotating speed of the fan.
For example, in the system shown in fig. 1 and fig. 2, a control and B control are each other controlled, and C control and D control are each other controlled, where a control and C control are used as the first controller, B control and D control are used as the second controller, that is, the reference point for a control can be the IO small card inside controller a, IO large card and IO small card controlled by B, the reference point for B control can be the IO small card inside controller B, IO small card, IO large card and IO small card controlled by a, the reference point for C control can be the IO small card inside controller C, IO small card, IO large card and IO small card controlled by C, and the reference point for D control can be the IO small card inside controller D, IO small card, IO large card and IO small card controlled by C.
In some embodiments, in S2, the PWM value corresponding to the first reference point of the multiple reference points of the first controller is sent to the second controller, and the PWM value corresponding to the first reference point of the multiple reference points of the second controller is sent to the first controller, specifically, since the air duct of the fan corresponding to the first controller can only align with half of the area of the IO mini-card under control, and the other half of the area of the IO mini-card aligns with the air duct of the second controller, the PWM value corresponding to the first reference point (i.e., the IO mini-card) of the first controller can be sent to the second controller, and the PWM value corresponding to the first reference point of the second controller is sent to the first controller. And then compared to the PWM values of its own multiple reference points.
In some embodiments, further comprising:
determining a maximum PWM value in the PWM values corresponding to the multiple reference points of the second controller in response to that the PWM values corresponding to the first reference point of the first controller are not all larger than the PWM values corresponding to the multiple reference points of the second controller;
and setting the fan rotating speed corresponding to the second controller according to the maximum PWM value.
In some embodiments, further comprising:
determining the maximum PWM value in the PWM values corresponding to the multiple reference points of the first controller in response to that the PWM values corresponding to the first reference point of the second controller are not all larger than the PWM values corresponding to the multiple reference points of the first controller;
and setting the fan rotating speed corresponding to the first controller according to the maximum PWM value.
Specifically, if the PWM values sent by the received pair control are all greater than the PWM values of the multiple reference points of the local control, it is indicated that the temperature of the first reference point of the pair control is a heat dissipation bottleneck, and the received PWM values are used as a basis for adjusting the rotation speed of the fan of the local control. The fans of the two controllers participate in heat dissipation of the IO small card of the same controller together, so that the heat dissipation of the IO small card is faster, and a new bottleneck point can be selected continuously after the temperature is reduced, so that the energy consumption and the noise are lower under the same load scene.
If the PWM values sent by the received pair control are not all larger than the PWM values of the multiple reference points of the local control, the temperature of a certain reference point of the local control is the heat dissipation bottleneck, and the PWM value corresponding to the reference point is used as the basis for adjusting the rotating speed of the fan of the local control. Comparing the local control internal PWM value, the local control IO single attribution card PWM value, the IO full attribution card PWM value and the pair control (B control) IO small card PWM value, wherein the maximum PWM value is the final speed regulation reference point of the local control and is used as the PWM speed regulation value of the local control fan.
In some embodiments, the obtaining, by the first controller and the second controller, the temperatures of the corresponding reference points, and calculating the PWM value according to the temperatures, further includes:
determining a master controller in response to the system including a plurality of first controllers and a plurality of second controllers;
acquiring the temperature of a second reference point in the multiple reference points by using the main controller, and calculating a PWM value according to the temperature of the second reference point;
and sending the calculated PWM value corresponding to the second reference point to other controllers.
Specifically, as shown in fig. 1 and fig. 2, the IO big card corresponds to air ducts of 4 fans, that is, the IO big card serves as a common speed regulation reference point for the a/B/C/D four controllers, and when the temperature of a certain IO big card is a heat dissipation bottleneck point for all four controllers, all four controllers use the temperature of the big card corresponding to the PWM value as a fan speed regulation value to dissipate heat of the IO big card. One controller can be selected from the four controllers as a main controller, the BMC of the main controller is used for obtaining the temperature of the IO big card (a second reference point), and the temperature is calculated into a PWM value and then sent to the BMCs of the other controllers so as to judge the heat dissipation bottleneck point.
Therefore, the fans corresponding to the controllers are not only limited to heat dissipation of the controllers and the IO cards to which the controllers belong, but also need to carry out speed regulation and heat dissipation on the IO cards to which other controllers belong in the area corresponding to the air channel, so that the energy efficiency grade is higher, and more energy is saved. Taking the IO small card corresponding to the A/B area as an example to perform simulation analysis, when the IO small card controlled by the A is heavily loaded and the whole IO small card controlled by the B is lightly loaded, if a single-control independent speed regulation strategy is adopted, the IO small card corresponding to the A control can be maintained within the temperature critical value by the A control with the fan rotating speed of 80 PWM values, and the total PWM value of the A/B control is 100. If a global speed regulation strategy is adopted, the A/B control jointly participates in heat dissipation of the A-control heavy-load IO small card, namely the temperature of the A-control IO small card is used as a fan rotating speed regulation reference by the fans of the A control and the B control, and the temperature of the A-control IO small card can be reduced more quickly.
