Since the blade server system currently using the air-cooling technology includes a fan module and a duct, all the blade servers are statically dissipated by the fan module and the air duct, and the blade server system In the case where each blade server works regardless of whether it is working or not, the blade server system dissipates heat for it, which obviously wastes a limited amount of wind channel resources. Therefore, the main idea of the solution of the present invention is that the air duct is close to the blade server side. The air duct partition corresponding to the blade server is set, and the opening/closing of the corresponding air duct partition is controlled according to the operation condition of each blade server in the blade server system. Obviously, turning off the air duct partition corresponding to some blade servers can increase the wind speed of the wind circulating in the air duct partition corresponding to other blade servers, thereby speeding up heat dissipation.

The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

In the blade server system of the solution of the present invention, there may be one fan module or multiple fan modules, and the specific implementations are completely the same. Therefore, for convenience of description, the following is an example of a blade server system including two fan modules and one air duct.

The structure of the blade server system of this embodiment is as shown in Fig. 3. The blade server system 30 shown in FIG. 3 includes ten blade servers 31-1 to 31-10, and a management module 35 for controlling the blade servers, and further includes a corresponding blade server. Air duct partition 36. These air duct partitions are specifically disposed on the side of the air duct 34 near the blade server, and may be specifically disposed on the housing of the blade server system or on each blade server of the blade server system. In addition, the blade server system is further provided with two fan modules 32 and 33.

According to the structure shown in FIG. 3, the management module in the blade server system determines the operation status of each blade server in the blade server system, and controls the wind corresponding to each blade server according to the operation condition. The track partition opens or closes. Specifically, when determining that the blade server enters the running state in the blade server system, the management module notifies that the air channel partition corresponding to the blade server is open; when it is determined that the blade server enters the closed state , to inform the blade server that the corresponding air duct partition is closed.

The air duct partition in the blade server system opens the partition after receiving the notification of opening the partition of the management module, and closes the partition after receiving the notification of closing the partition of the management module.

In order to save the wind channel resources, the air duct partition can be set to be in a closed state under normal conditions.

Correspondingly, the management module can continue to monitor the blade server after the blade server enters the running state and notify the corresponding air channel partition of the blade server to open the partition, if the blade server is operated by When the status changes to the stop state, the air duct partition corresponding to the blade server is notified to close the partition; otherwise, the monitoring is continued.

In addition, the air duct partition provided in the present invention may be specifically as shown in FIG. 4, that is, the air duct partition 40 is composed of a drive motor 41 and a partition plate 42, wherein the drive motor may be a servo motor or It is another motor. The partition can be switched by the drive motor. The drive motor opens/closes the partition under the control of the management module. And the partition may be a door having a rotating shaft in the middle, when the door is controlled by the rotating shaft, parallel to the other fixed portions of the partition, the partition is closed; when the door is integrated with other fixed parts of the partition At the angle, the partition is opened, and obviously, if the angle is 90 degrees, the partition is fully opened. Of course, if it is disposed on the casing, all the air duct partitions can be arranged as one air duct partition strip, as shown in Fig. 5, and each blade servo corresponds to one air duct partition. As shown in Fig. 5, each of the duct spacer strips 52-1, 52-2, ..., 52-n is disposed in each of the drive motors 51-1, 51-2, ..., 51-n.

The above solution mainly controls the opening/closing of the air channel partition corresponding to the blade server according to the operation of each blade server. Based on the above solution, the present invention further provides a solution for controlling the opening angle of the air duct partition according to the operation of the blade server. The scheme is described in detail below.

The solution for controlling the opening angle of the air duct partition proposed by the present invention has two implementation modes, one of which is directly controlled according to the temperature of each blade server; since the power consumption of the blade server is proportional to the temperature, the power consumption The higher the temperature, the higher the temperature, so another way is to control according to the power consumption of each blade server.

If the temperature is controlled, it is first necessary to further set a corresponding temperature acquisition module for each blade server in the blade server system, and the temperature collection module can usually be a sensor. The temperature collection module sends the collected temperature information to the management module.

The management module further determines the opening angle of the air duct partition of each blade server in the running state according to the obtained temperature information. Specifically, the management module can control the air duct partition corresponding to the highest temperature blade server to be fully opened, and control the air duct partition corresponding to the remaining blade servers to open a certain angle. In the specific implementation, the management module sends all the open signals to the air channel partition corresponding to the highest temperature blade server, and sends a signal corresponding to the specific angle to the corresponding air channel partition of the remaining blade servers. .

Moreover, when determining the opening angle of the air duct partition of the remaining blade servers, if the temperature of the blade server is lower than a certain value, the opening angle of the air duct partition corresponding to the blade server is reduced by a certain value. Angle, for example, if the temperature of the blade server is lower than the current maximum temperature by 1 ° C, the opening angle of the air duct partition corresponding to the blade server is reduced by 3 degrees. This calculation is shown in equation (1).

Opening angle = 90-3 × (Tmax-Tn) (1)

For example, the temperature collection module collects the temperature of ten blade servers, which are T1, T2, ..., T10, where T1 is 50 °C, T2 is 46 °C, and T3 is 48 °C. ... and send these temperature information to the management module. It is assumed that the management module determines that T1 is the current temperature maximum value Tmax. Therefore, the air duct partition corresponding to the blade server 1 should be fully open, and the management module sends the corresponding channel to the air channel partition corresponding to the blade server 1. All open signals, and calculate the opening angles of the remaining blade servers according to formula (1), which is calculated by formula (1), and the opening angle corresponding to blade server 2 is 90-3×(50-46)=78 The blade server 3 has an opening angle of 90-3×(50-48)=84, similarly, the opening angles of the remaining blade servers are obtained, and the blade servers are respectively provided according to the calculated opening angles. The corresponding air duct partition sends a signal to open the corresponding angle.

Of course, the above formula (1) is only a preferred embodiment of the present invention, and other opening angle calculation schemes may be set as needed.

The above-described implementation of adjusting the opening angle of the air duct partition of each blade servo according to the temperature is described below, and an implementation scheme of adjusting the opening angle of the air duct partition according to the power consumption of each blade server will be described below.

Since the management module in the blade server system can obtain the power consumption of each blade server, the management module can directly obtain the power consumption of each blade server in the running state, and according to the obtained power consumption information. Determine the opening angle of the air duct partition of each blade server. Specifically, the management module can control the air channel partition corresponding to the blade server with the highest power consumption to be fully opened, and control the air channel partition corresponding to the remaining blade servers to open a certain angle. In a specific implementation, the management module sends a full open signal to the air channel partition corresponding to the blade server with the highest power consumption, and sends a specific angle corresponding to the corresponding air channel partition of the other blade server. signal.

Moreover, when determining the opening angle of the air duct partition of the remaining blade servers, the power consumption of the blade server may be reduced by a certain value when the power consumption of the blade server is lower than a certain value. Angle. For example, if the power consumption of the blade server is lower than the current maximum power consumption by 5 W, the opening angle of the air channel partition corresponding to the blade server is reduced by 1 degree. This calculation is shown in equation (2).

Opening angle = 90-(Pmax-Pn)/5 (2)

Of course, the above formula (2) is also only a preferred embodiment of the present invention, and other opening angle calculation schemes may be provided as needed.

According to the above formula (2), the management module can obtain the opening angle of the air duct partition of each blade server. After that, send corresponding signals to each air channel partition.

After the air duct spacer corresponding to each blade server is disposed in the blade server system, the implementation flow of the method of the present invention is as shown in FIG. 6, which includes steps 601 and 602. The specific arrangement of the air duct partition is as before, and will not be described here. The implementation process specifically corresponds to the following steps: Step 601: The blade server system determines the running status of each blade server.

Step 602: The blade server system controls the air channel partition corresponding to the blade server in the running state to be in an open state, and controls the air channel partition corresponding to the blade server in the non-operating state to be in a closed state.

The above is the implementation flow of the method of the present invention.

In order to ensure that the air channel resources are fully utilized, the opening angle of the air duct partition can also be controlled according to the operation condition of the blade server, that is, in the above step 602, the blade server system corresponds to the blade server that controls the running state. When the air duct partition is in an open state, the opening angles of the air duct partitions corresponding to the respective blade servers may be determined according to the temperature or power consumption of each blade server, and the air passage partitions are controlled to open corresponding angles. .

If the opening angle of the air duct partition corresponding to each blade server is determined according to the temperature, it is necessary to add a temperature collecting module to the blade server system. Then, in the above step 602, when the blade server corresponding to the blade server that controls the running state is in an open state, the blade server system can further obtain the blade server according to the temperature collecting module. The temperature to control the opening angle of the air duct partition corresponding to these blade servers. The control may be specifically achieved by transmitting signals corresponding to the required opening angles to the air ducts.

When the blade server system controls the opening angle of the air channel partition corresponding to the blade server in the running state, specifically, the opening angle of the air channel partition corresponding to the blade server with the highest current temperature setting is 90. Degree, the opening angle of the air duct partition corresponding to other blade servers is calculated according to the above formula (1). Of course, this is only a preferred embodiment, and the opening angles of other air duct partitions can also be obtained by other similar algorithms.

If the opening angle of the air channel partition corresponding to each blade server is determined according to the power consumption, the power consumption of each blade server can be directly obtained by the blade server system, and in the above step 602, the blade servo When the air channel partition corresponding to the blade server that controls the running state is in an open state, the air channel partition corresponding to the blade servers can be further controlled by acquiring the power consumption of the blade servers. Open the angle. This control can also be achieved by transmitting signals corresponding to the required opening angles to these air ducts.

When the blade server system controls the opening angle of the air channel partition corresponding to the blade server in the running state, specifically, the opening angle of the air channel partition corresponding to the blade server with the largest current power consumption is set to 90. Degree, the opening angle of the air duct partition corresponding to other blade servers is calculated according to the above formula (2). Again, this is only a preferred embodiment, and the opening angles of other duct spacers can be obtained by other similar algorithms.

Further, referring to FIG. 7, as shown in FIG. 7, the blade server system 70 includes: servers 71-1 to 71-10, and a fan 72. As can be seen from Figure 7, the existing blade server system dissipates the blade server regardless of whether it is running or not. The wind of the blade server in the running state is the same as the wind of the blade server that is not running. Therefore, the heat dissipation effect of the blade server in the running state is general. Finally, please refer to FIG. 8. As shown in FIG. 8, the blade server system 80 includes: blade servers 81-1 to 81-10, a fan 82, and partitions 83-2, 83-4. , 83-6, 83-8, and 83-10. As can be seen from FIG. 8 , the solution of the present invention increases the operation state by providing a duct partition in the blade server system so that no wind passes through the blade server that is not running. The blade wind speed of the blade server, in turn, enables the blade server in operation to have better heat dissipation.

The above is only a preferred implementation of the solution of the present invention, and is not intended to limit the scope of the present invention.
