Description of the Invention: [Technical Field] The present invention relates to a multi-board server and a multi-board server control method, and more particularly to a multi-board with power consumption control function The power consumption control method of the server and the multi-board server. [Prior Art] With the rapid development of digital technology, the application of digital products is becoming more and more popular. The progress of computer-related peripheral industries is even more than a thousand miles. With the rapid development of computers and the rapid development of network technology, the Internet has become an important medium for rapid access to information and can provide a variety of information services. As a result, the current use of the Internet has made it necessary for network-related operators to purchase a large number of network and computer-related equipment to fully meet the needs of users. However, due to the limited space available in the equipment room, it is desirable to have a smaller size for the computer and associated equipment to reduce the office or factory space it occupies. In particular, the large-scale computer server system, in order to achieve high stability, is still more than the size of a typical desktop computer. Therefore, the development of the server has focused on providing higher processing performance per unit volume of the server and enabling flexible deployment in the server. Thus, a server having a plurality of independent motherboards in one chassis has been developed. However, multi-board servers are currently unable to change their power consumption. Therefore, the multi-board server cannot set different power consumption according to the needs of the user, which is inconvenient for the user. 201222232 SUMMARY OF THE INVENTION Accordingly, it is an aspect of the present invention to provide a multi-board server having a power consumption control function. After receiving the total power consumption setting, the multi-board server converts the total power consumption setting to the single motherboard power consumption limit. When the power consumption of the motherboard is greater than the upper limit of the power consumption of the single motherboard, the processing component is overheated to the processing component on the motherboard that consumes too much power, thereby reducing the operating frequency of the processing component to reduce power consumption. the amount. A multi-board server with power consumption control includes a data transfer interface, a user interface, a control board, and several motherboards. The control board is electrically connected to the data transmission interface and is connected to the user interface. Each motherboard is electrically connected to the data transmission interface. The control panel includes a setting receiving module, a computing module and a transmitting module. The receiving module is configured to receive a total power consumption setting through the user interface. The calculation module calculates the maximum power consumption of a single motherboard according to the total power consumption setting. The transmission module transmits the maximum power consumption of a single motherboard through the data transmission interface. Each motherboard includes at least one processing component and a substrate management controller. The substrate management controller and processing elements on the same motherboard are electrically connected to each other. Each of the substrate management controllers includes an upper limit receiving module, a determining module, and a down-converting module. The upper limit receiving module receives the upper limit of the power consumption of a single motherboard through the data transmission interface. The judging module judges whether the current power consumption of one of the motherboards configured by the baseboard management controller is greater than the upper limit of the power consumption of the single motherboard. The down-conversion module transmits a processing component to the processing element of the same motherboard when the current power consumption is greater than the upper limit of the power consumption of the single motherboard. Therefore, after receiving the processing component overheat signal, the processing component of the same motherboard reduces the current operating frequency of one of the processing components by 201222232 to reduce the current power consumption. According to an embodiment of the invention, the computing module can include a divider. The upper limit of the power consumption of a single motherboard is obtained by dividing the total power consumption setting by the number of the motherboard by the divider. According to another embodiment of the present invention, the user interface is electrically connected to one of the substrate controllers, and the user interface is configured to enable the electrically connected substrate management controller to transmit the total power consumption to the control through the data transmission interface. board. Another aspect of the present invention provides a Φ power control method for a multi-board server for use in a multi-board server. Among them, the multi-host server contains several motherboards. Each motherboard contains at least one processing element. After receiving the total power consumption setting for one of the multiple motherboard servers, the total power consumption setting is converted to the single motherboard power consumption limit. When the power consumption of the motherboard is greater than the upper limit of the power consumption of the single motherboard, the processing component is overheated to the processing component on the motherboard that consumes too much power, thereby reducing the operating frequency of the processing component to reduce power consumption. the amount. The power consumption control method of the multi-board server includes: receiving a total power consumption setting. Calculate the maximum power consumption of a single motherboard based on the total power consumption $ setting. Get the current power consumption of each motherboard. Determine whether the current power consumption of each motherboard is greater than the maximum power consumption of a single motherboard. When at least one of the current power consumption of the plurality of motherboards is greater than the upper limit of the power consumption of the single motherboard, the motherboard that currently consumes more power than the upper limit of the power consumption of the single motherboard is regarded as a superheated motherboard, and A processing component overheat signal is transmitted to the processing element on the overheated motherboard. Therefore, after the processing component on the overheated motherboard receives the processing component overheating signal, the current operating frequency of one of the processing components on the overheated motherboard is reduced to reduce the current power consumption. According to an embodiment of the present invention, according to the total power consumption setting, calculating an upper limit of the power consumption of the single motherboard includes: dividing the total power consumption setting value by the number of the motherboard to obtain a single motherboard power consumption. The upper limit. In accordance with another embodiment of the present invention, each motherboard includes a substrate management controller. Wherein, when at least one of the current power consumption of the motherboard is greater than the upper limit of the power consumption of the single motherboard, the processing element overheating signal is transmitted from the substrate management controller on the overheated motherboard to the processing component on the overheated motherboard. • The application of the present invention has the following advantages. Users can set the total power consumption of the multi-board server. In this way, the user can give different multi-board server different total power consumption settings according to their needs. In addition, the existing processing component overheating signal can be used to reduce the power consumption of the motherboard, and no additional design is required to reduce the power consumption. BRIEF DESCRIPTION OF THE DRAWINGS The spirit of the present invention will be clearly described in the following drawings and detailed description, which is to be understood by those of ordinary skill in the art of the present invention. Changes and modifications may be made without departing from the spirit and scope of the invention. Please refer to FIG. 1 , which is a functional block diagram of a multi-board server with a power control function according to an embodiment of the invention. The multi-board server with power consumption control converts the total power consumption setting to the single-board power consumption limit after receiving a total power consumption setting. When the power consumption of the motherboard is greater than the upper limit of the power consumption of the single motherboard, the processing component is overheated to the processing component on the motherboard that consumes too much power, thereby reducing the operating frequency of the processing component of 201222232 to reduce power consumption. the amount. The multi-board server with power consumption control function includes a data transmission interface 100, a user interface 200, a control board 300, and a plurality of motherboards 400, 500. The control board 300 is electrically connected to the data transmission interface 1 and is connected to the user interface 200. Each of the motherboards 400 and 500 is electrically connected to the data transmission interface 100. The data transmission interface 100 can be an intelligent platform management bus (IPMB) or other data transmission interface, and the control board 300 can be a fan control board (FCB) or other computing power control board. The control board 300 includes a setting receiving module 310, a computing module 320, and a transmitting module 330. The setting receiving module 310 receives a total power consumption setting through the user interface 200. In other words, the user can set the total power consumption setting of the multi-board server with the power consumption control function through the user interface 200. The calculation module 320 calculates an upper limit of the power consumption of a single motherboard according to the total power consumption setting. In an embodiment, computing module 320 can include a divider 321 . Therefore, the upper limit of the power consumption of the single motherboard is obtained by dividing the value of the total power consumption by the divider 321 by the number of the motherboards 400, 500. In another embodiment, the computing module 320 can firstly use the power consumption of components other than the motherboard 400, 500 (such as a fan, a hard disk, or other components) in the multi-board server with the power consumption control function. After subtracting from the total power consumption setting, the number of the motherboards 400 and 500 is divided by the maximum power consumption of the single motherboard. However, in other embodiments, the calculation module 320 can calculate the maximum power consumption of a single motherboard according to the total power consumption setting by other calculation methods, and is not limited to the disclosure. The transmission module 330 transmits the maximum power consumption of the single host 201222232 board through the data transmission interface. Each motherboard 400, 500 includes a substrate management controller 410, 510 and at least one processing component 420, 520. The substrate management controllers 410, 510 and the processing elements 420, 520 on the same motherboard 400, 500 are electrically connected to each other. Each of the substrate management controllers 410, 510 includes an upper limit receiving module 411, 511, a determining module 412, 512, and a down-converting module 413, 513. The upper limit receiving modules 411, 511 receive the upper limit of the power consumption of a single motherboard. The determining module 412, 512 determines whether the current power consumption of one of the motherboards 400, 500 configured by the substrate management controllers 410, 510 is greater than the upper limit of the power consumption of the single motherboard. In an embodiment of the present invention, the determining modules 412, 512 can calculate the current power consumption of the motherboards 400, 500 by the current amount of current of the motherboards 400, 500. In another embodiment of the present invention, a total current amount setting can be regarded as a total power consumption setting of a plurality of host board servers having a power consumption control function, and an upper limit of a single board current amount can be calculated. Therefore, the determining module 412, 512 can determine the motherboard 400 configured by the substrate management controller 410, 510 by determining whether the current current amount of one of the configured motherboards 400, 500 is greater than a single motherboard current limit " Whether the power consumption of the 00 is greater than the upper limit of the power consumption of the grass one motherboard. However, in other embodiments, the determination modules 412, 512 can be judged by other judgment methods, and are not limited to the disclosure. Since the processing elements 420, 520 are the most power consuming components on the motherboards 400, 500, the processing elements 420, 520 can be downconverted to reduce power consumption when power consumption is excessive. Thus, the down-converting modules 413, 513 transmit a processing component overheat signal to the processing elements 420, 520 of the same motherboard 400, 500 when the current power consumption is greater than the upper limit of the power consumption of the single motherboard. The processing component overheating signal may be PR0CH0T# or other types of processing components 201222232 overheating signal. After the processing elements 420, 520 of the same motherboard 400, 500 receive the processing component overheat signal, the current operating frequency of one of the processing components, 52 降低 is reduced to reduce the current power consumption. The user can set one of the motherboards of the multi-board server with power consumption control function to set the total power consumption setting. Therefore, in an embodiment of the invention, the user interface 200 is electrically connected to the substrate controller 410 of one of the motherboards 400. The user interface 200 is configured such that the electrically connected baseboard management controller 410 transmits the total power consumption φ to the control board 300 through the data transmission interface. The motherboard 400 can provide a basic input/output system (BIOS) setting interface as the user interface 200. However, in other embodiments, the user interface 200 can be a keyboard, a mouse, a touch panel, a graphical user interface (GUI), or other types of software or hardware user interfaces. This disclosure. In this way, the user can set the overall power consumption of the multi-board servos with power consumption control function on one of the motherboards 400. • In addition, multiple motherboard servers with power consumption control can recalculate the maximum power consumption of a single motherboard when one of the multiple power supplies used to power fails. Therefore, the multi-board server may further include a plurality of power supplies 101, 102, and the control board may further include a fault processing module 340. The power supplies 1〇1, 1〇2 provide power to multiple motherboard servers with power consumption control. In the event of a failure of the power supplies 1〇1, 1〇2, the fault handling module 340 calculates the upper limit of the power supply for the unfailed power supply. The fault handling module 340 causes the computing module 32 to calculate the upper limit of the power consumption of the single motherboard based on the total power consumption setting and the power supply upper limit. In 201222232, when the set total power consumption is set to be greater than the upper limit of the power supply, the calculation module 320 calculates the power consumption of a single motherboard according to the upper limit of the power supply of the unpowered power supply. When the set total power consumption setting is not greater than the upper limit of the power supply amount, the calculation module 320 calculates the power consumption of the single motherboard according to the total power consumption setting. As a result, when one of the power supplies 101, 102 fails, the power can be normally supplied to the multi-board server having the power consumption control function. Please refer to FIG. 2, which is a flowchart of a power consumption control method of a multi-board server according to an embodiment of the present invention. The power consumption control method of the multi-board server is applied to a multi-board server. Among them, the multi-board server contains several motherboards. Each motherboard contains at least one processing component. In the power consumption control method of the multi-board server, after receiving the total power consumption of one of the multi-board servers, the total power consumption setting is converted into the upper limit of the power consumption of the single motherboard. When the power consumption of the motherboard is greater than the upper limit of the power consumption of the single motherboard, the processing component is overheated to the processing component on the motherboard that consumes too much power, thereby reducing the operating frequency of the processing component to reduce power consumption. the amount. The power consumption control method 600 of the multi-board server includes: In step 610, a total power consumption setting is received. The total power consumption setting can be received from a user interface (step 610). The user interface can be a keyboard, a mouse, a touch panel, a graphical user interface, a basic input/output system setting interface, or other types of software or hardware user interfaces. In step 620, a single motherboard power consumption cap is calculated based on the total power consumption setting. In one embodiment, the single motherboard power consumption limit is 201222232 divided by the total power consumption setting divided by the number of motherboards in the multi-board server. In another embodiment, the power consumption of the components other than the motherboard in the multi-board server may be subtracted from the total power consumption, and then divided by the number of the motherboard to consume power as a single motherboard. The upper limit. However, in other embodiments, step 620 can calculate a single motherboard power consumption limit based on the total power consumption setting by other calculation methods, and is not limited to the disclosure. In step 630, the current power consumption of one of each motherboard is obtained. In step 640, it is determined whether the current power consumption of each motherboard is φ or not greater than the upper limit of the power consumption of a single motherboard. In an embodiment of the invention, the current power consumption of the motherboard can be calculated and obtained by the current amount of current of the motherboard (step 630). In another embodiment of the present invention, a total current amount setting can be regarded as a total power consumption setting of a plurality of motherboard servers having a power consumption control function, and a single motherboard current limit is calculated (steps) 620). Then, step 640 can determine whether the current power consumption of the motherboard is greater than the upper limit of the power consumption of the single motherboard by determining whether the current current of one of the motherboards is greater than the upper limit of the current of the single motherboard. However, in other embodiments, the step 640 can be judged by other judgment methods, and is not limited to the disclosure. Since the processing component is the most power-consuming component on the motherboard, the processing component can be down-converted to reduce power consumption by processing the component overheating signal when the power consumption is too large. Therefore, in step 650, when at least one of the current power consumption of the plurality of motherboards is greater than the upper limit of the power consumption of the single motherboard, the motherboard with the current power consumption exceeding the upper limit of the power consumption of the single motherboard is regarded as For a superheated motherboard. In step 660, a processing component overheat signal is transmitted to the processing element on the overheated host board. The processing component overheating signal may be PROCHOT#[s] 12 201222232 or other types of processing component overheating signals. Then, in step 670, after the processing component on the overheated motherboard receives the processing component overheat signal, the current operating frequency of one of the processing components on the overheated motherboard is reduced to reduce the current power consumption. In this way, the power consumption of the motherboard can be reduced without requiring an additional command to reduce the power consumption. In addition, each motherboard may include a substrate management controller. Therefore, the judgment of step 640 can be performed by the baseboard management controller on each motherboard, and the superheated motherboard is used when at least one of the current power consumption of the motherboard is greater than a single φ and the upper limit of the power consumption of the motherboard. The upper substrate management controller transmits the processing component overheat signal to the processing component on the overheated motherboard (step 650). In this way, the power consumption of each motherboard can be controlled by the substrate management controller on each motherboard. No additional components are required. In addition, if multiple power supplies are used to power up to multiple motherboard servers and one of the multiple power supplies used to power the unit fails, the maximum power consumption of the single board can be re-used. Therefore, in step 68, it can be judged whether there is a power supply failure. In the absence of a power supply failure, the current power consumption of each motherboard is continuously taken (step 030). In step 690, when the f power supply fails, the upper limit of one of the unpowered power supplies is calculated, and the single main power consumption upper limit is calculated according to the total power consumption setting and the power supply upper limit. Therefore, in the set total power consumption on the second power limit day 2 step _ according to the power supply, the upper limit of the power supply, the upper limit, calculate the power consumption of a single motherboard. When the set total power consumption is set to be greater than the upper limit of the power supply amount, step 690 calculates the power consumption of the single motherboard according to the total power consumption setting. In this way, in the event of a failure of multiple power supplies, the power supply to the multi-board feeder can still be normally supplied and the 201222232 line power consumption control is normally performed. It will be apparent from the above-described embodiments of the present invention that the application of the present invention has the following advantages. The user can set the total power consumption of the multi-board server. In this way, the user can give different multi-board server different total power consumption settings according to their needs. In addition, the existing processing component overheating signal can be used to reduce the power consumption of the motherboard, and no additional design is required to reduce the power consumption. While the invention has been described above by way of example only, the invention is not intended to be limited thereto, and the invention may be modified and modified without departing from the spirit and scope of the invention. The scope of protection is subject to the definition of the scope of the patent application attached.
