[0002] The server consists of a motherboard, baseboard management controller (BMC), network card, hard disk, and power supply. The motherboard includes core components such as processors and memory, high-speed connectors, and fan modules. At present, when designing a server, the layout of components on the motherboard is fixed, the motherboard is placed in a fixed position on the server, and the motherboard is fixedly connected to the power supply, network card, hard disk, and BMC. This fixed connection method makes it difficult for the server to flexibly adapt to the needs of different business configurations, deployments, and applications. Summary of the invention

[0003] The embodiment of the present application provides a server and a main control board, wherein the main control board of the server can be flexibly adjusted to flexibly adapt to the requirements of different business configurations, deployments and applications.

[0004] In order to achieve the above purpose, the embodiment of the present application adopts the following technical solution:

[0005] In the first aspect, an embodiment of the present application provides a server. The server includes a main control board, a fan board, a hard disk module and an expansion module. Among them, the hard disk module includes multiple hard disks, and the expansion module can be a network card module, a data processing unit module and a neural processing unit (NPU) module, or it can be other, such as a power supply, which is not specifically limited in the embodiment of the present application.

[0006] The main control board includes a processor, a memory, a first signal connector, and a first high-speed connector group and a second high-speed connector group located on opposite sides of the processor. The number of high-speed connectors included in the first high-speed connector group is greater than the number of high-speed connectors included in the second high-speed connector group, and each high-speed connector is connected to the processor. The fan board is adjacent to one side of the main control board, and the fan board includes a fan and a second signal connector. The first signal connector is connected to the BMC of the server, and the second signal connector is connected to the first signal connector. Thus, the BMC can communicate with the fan to monitor and manage the running status of the fan. The hard disk module is located on the side of the fan board away from the main control board, and the extension module is located on the side of the main board away from the fan board. The main control board is installed in a first position or a second position. In the first position, the first high-speed connector group is arranged close to the fan board and connected to the hard disk module, and the second high-speed connector group is close to the extension module and connected to the extension module. In the second position, the first high-speed connector group is close to the extension module and connected to the extension module, and the second high-speed connector group is close to the fan board and connected to the hard disk module.

[0007] In the embodiment of the present application, the server can adjust the installation position of the main control board as needed. For example, when the storage capacity of the server needs to be expanded, more hard disk modules need to be configured. At this time, the main control board is installed in the first position, so that the side with more high-speed connectors is connected to the hard disk. When more or stronger expansion functions are needed, the main control board is installed in the second position, so that the side with more high-speed connectors is connected to the network card. Therefore, by adjusting the installation position of the main control board of the server, it is not necessary to modify the position of the high-speed connector on the main control board, and it is possible to flexibly adapt to the needs of different business configurations, deployments, and applications.

[0008] In a specific implementation, the server further includes an expansion board, which is arranged between the main control board and the expansion module; the expansion board includes a baseboard management controller and a third signal connector; the main control board also includes a fourth signal connector; the third signal connector is connected to the baseboard management controller; the third signal connector is connected to the fourth signal connector.

Thus, when the main control board is in different positions, the connection between the power supply and the power connector ensures the normal operation of the main control board.

[0012] Furthermore, the power connector on the third side and the power connector on the fourth side are interconnected by using an L-shaped copper busbar.

The main control board is connected to the power supply through the expansion board, and when the power supply needs to be replaced or upgraded, it is easier to disconnect through the expansion board without disassembling the entire server or the main control board, and the presence of the expansion board allows one or more backup power supplies to be added, thereby improving the fault tolerance and reliability of the server.

[0014] In another implementation, the main control board also includes a heat sink, which is disposed on the top of the processor and has a consistent relative distance to each side of the processor, thereby ensuring heat dissipation consistency of the heat sink.

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings.

Specifically, the use of words such as "exemplary", "for example" or "for example" is intended to present related concepts in a concrete way.

[0034] In the description of the embodiments of the present application, the term "and / or" is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, B exists alone, and A and B exist at the same time. In addition, unless otherwise specified, the term "multiple" means two or more. For example, multiple systems refers to two or more systems, and multiple terminals refers to two or more terminals.

[0035] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. The terms "include", "comprises", "has" and their variations all mean "including but not limited to", unless otherwise specifically emphasized.

[0036] As mentioned above, the server motherboard includes core components such as processors, memory, and high-speed connectors. The processor is connected to the hard disk module through a high-speed connector, or to expansion modules such as the network card module through a high-speed connector. Since the high-speed interface of the processor is fixed and the high-speed interface is unevenly distributed on the processor, the position of the high-speed connector connected to the high-speed interface is fixed. In addition, the placement position of the main control board on the server is fixed, that is, the motherboard is fixedly connected to the power supply, network card module, hard disk, BMC, etc. This fixed connection method makes it difficult for the server to flexibly adapt to the needs of different business configurations, deployments, and applications.

[0037] In view of the above problems, an embodiment of the present application provides a server, which is divided into a main control board, a fan board, a hard disk module and an expansion module, wherein the main control board includes a processor, a memory, a high-speed connector and a signal connector, and the fan board includes a fan and a second signal connector. The main control board is thereby decoupled from other components. On the one hand, this decoupling method can adapt to different scenarios by adjusting the position of the main control board, thereby adapting to diversified design requirements and improving design flexibility. On the other hand, rotating the main control board in an embodiment of the present application can reduce the impact on other links.

[0038] The server main control board provided in the embodiment of the present application is described in detail below in conjunction with the accompanying drawings.

[0039] Embodiment 1

[0040] Attached Figure 1 A schematic diagram of the structure of a server provided in an embodiment of the present application.

[0041] like Figure 1 As shown, the server 100 includes a main control board 101 , a hard disk module 102 , an expansion module 103 and a fan board 104 .

[0042] The hard disk module 102 is located on a side of the fan board 104 away from the main control board 101 . The expansion module 103 is disposed on a side of the main control board 101 away from the fan board 104 .

[0043] The hard disk module 103 includes at least one hard disk, which provides storage space for the server 100 and is used to store the server's operating system files, boot loader and system files.

[0044] The expansion module 103 includes one or more expansion devices, such as a network card, a data processing unit (DPU) or a neural processing unit (NPU), etc., which is not specifically limited in the embodiment of the present application. The server 100 can add or replace various expansion devices as needed.

[0045] The main control board 101 is the core of the server 100 , integrating key components such as a processor and a memory, and is responsible for coordinating and managing the hardware resources of the server 100 .

[0046] In the embodiment of the present application, the main control board 101 includes a processor 101-4, a memory 101-3, a first signal connector 101-5, and a first high-speed connector group 101-1 and a second high-speed connector group 101-2 located on opposite sides of the processor 101-4.

[0047] It can be understood that the processor 101-4, the memory 101-3, the first signal connector 101-5, and the first high-speed connector group 101-1 and the second high-speed connector group 101-2 located on opposite sides of the processor 101-4 are arranged on the main control board 101. When the main control board 101 rotates, the processor 101-4, the memory 101-3, the first signal connector 101-5, and the first high-speed connector group 101-1 and the second high-speed connector group 101-2 located on opposite sides of the processor 101-4 also rotate synchronously.

[0048] In an embodiment of the present application, the fan board 104 provides a heat dissipation function for the server 100. The fan board 104 is adjacent to the main control board 101 and directly dissipates heat for key components on the main control board 101, such as the processor 101-4, memory 101-3, etc., to ensure that the key components of the main control board 101 can still work normally at high temperatures.

[0049] The fan board 104 includes a fan (not shown) and a second signal connector 104-1. The first signal connector 101-5 of the main control board 101 is connected to the second signal connector 104-1, and the first signal connector 101-5 is connected to the BMC 106 of the server. Thus, communication signals can be transmitted between the BMC 106 and the fan.

[0050] Specifically, the BMC 106 can transmit a management signal to the fan through the first signal connector 101-5 and the second signal connector 104-1. The management signal can be a fan speed control signal to control the speed of the fan. The management signal can also be a switch control signal to control the start and stop of the fan. The management signal can also be other signals, such as a fault recovery signal. When the BMC 106 detects a fan fault, it sends a fault reset signal to try to restore the normal operation of the fan. The embodiments of the present application are not specifically limited.

[0051] The fan may report the communication signal of the operation information to the BMC 106 through the second signal connector 104-1 and the first signal connector 101-5. The operation information may be temperature information, rotation speed information, fault information, status information, etc. The embodiment of the present application is not specifically limited.

[0052] It should be noted that the first signal connector 101-5 and the second signal connector 104-1 may be an inter-integrated circuit (I2C) connector, or a serial peripheral interface (SPI) connector, etc., which is not specifically limited in the embodiment of the present application.

[0053] Furthermore, if Figure 2 As shown, the main control board 101 further includes a first logic device 101-6. The first logic device 101-6 is connected to the BMC 106 through the first signal connector 101-5, and the first logic device 101-6 is connected to the second signal connector 104-1 to transmit communication signals between the BMC and the devices on the fan board.

[0054] Among them, the first logic device 101-6 can be a programmable device such as a complex programmable logic device (CPLD) or a field-programmable gate array (FPGA), or it can be other control devices such as a controller, which is not specifically limited in the embodiments of the present application.

[0055] At this time, the BMC 106 can transmit the management signal to the fan through the first signal connector 101-5, the first logic device 101-6 and the second signal connector 104-1. The fan reports the operation information to the BMC 106 through the second signal connector 104-1, the first logic device 101-6 and the first signal connector 101-5. By introducing the first logic device, signal attenuation and noise interference can be reduced, and the integrity and reliability of signal transmission can be improved.

[0056] In the embodiment of the present application, the first signal connector and the second signal connector may be the same signal connector or different signal connectors, which is not specifically limited in the embodiment of the present application.

[0057] The high-speed connector group is described below.

[0058] In the embodiment of the present application, the first high-speed connector group 101-1 includes n high-speed connectors, and the second high-speed connector group 101-2 includes m high-speed connectors. m>1, and m is an integer, n>m, and n is an integer. The high-speed connectors in the first high-speed connector group 101-1 and the high-speed connectors in the second high-speed connector group 101-2 are both connected to the processor 101-4. Exemplarily, Figure 1 An example where n=2 and m=4 is used for schematic description.

[0059] Understandably, Figure 1 The number of high-speed connectors in the two high-speed connector groups can both be even numbers, or both be odd numbers, or one can be an odd number and the other can be an even number. The specific number is determined according to the processor design specifications and is not specifically limited in the embodiments of the present application.

[0060] It should be noted that the distribution of the high-speed connectors connected to the processor is determined by the high-speed interface of the processor. The high-speed interface of the processor is fixed and unevenly distributed, so the relative position of the high-speed connector on the main control board 101 is fixed.

[0061] A high-speed connector is a physical interface for transmitting high-speed data signals. High-speed connectors include but are not limited to the following connectors: Peripheral Component Interconnect Express (PCIe) connector, Serial Advanced Technology Attachment (Serial ATA) connector, etc.

[0062] In the embodiment of the present application, the main control board 101 can be installed in two positions, namely a first position and a second position.

[0063] like Figure 1 As shown, at the first position, the first high-speed connector group 101-1 is disposed close to the fan plate 104, and the second high-speed connector group 101-2 is disposed close to the expansion module 103. The high-speed connector in the first high-speed connector group 101-1 is connected to the hard disk module 102, and the high-speed connector in the second high-speed connector group 101-1 is connected to the expansion module 103.

[0064] like Figure 3 As shown, it is a schematic diagram of the structure of the main control board provided in the embodiment of the present application in the second position. At the second position, the second high-speed connector group 101-2 is arranged near the fan board 104, and the first high-speed connector group 101-1 is arranged near the expansion module 103. The high-speed connector in the second high-speed connector group 101-1 is connected to the hard disk module 102. The high-speed connector in the first high-speed connector group 101-1 is connected to the expansion module 103. Specifically, Figure 2 shown.

[0065] Need to explain, Figure 1 In the first position shown, the relative distance between the first high-speed connector group 101-1 of the main control board 101 and the fan board 104 is the smallest, and the relative distance between the second high-speed connector group 101-2 and the expansion module 103 is the smallest. This is only a schematic representation and can be adjusted as needed in actual use.

[0066] Figure 3 The second position shown is Figure 1 The first position shown is rotated 180 degrees. At this time, the relative distance between the second high-speed connector group 101-2 of the main control board 101 and the fan board 104 is the smallest. The relative distance between the first high-speed connector group 101-1 and the expansion module 103 is the smallest.

[0067] Need to explain, Figure 3The second position shown is for schematic illustration only. In actual use, the second position can also be a position where the first position is rotated by other angles, such as 120°, 240°, 360°, etc., and adaptive adjustments can be made according to specific needs, which is not specifically limited in the embodiments of the present application.

[0068] In the embodiment of the present application, the high-speed connector is connected to the expansion module 103 or the hard disk module 102 through a high-speed cable. In the embodiment of the present application, the high-speed connector close to the hard disk module is connected to the hard disk module, and the high-speed connector close to the expansion module is connected to the expansion module, which can reduce the length of the high-speed cable and the high-speed signal transmission path, thereby helping to reduce signal transmission delay and signal interference.

[0069] In the embodiment of the present application, the side where the first high-speed connector group is located is the first side S1, and the side where the second high-speed connector group is located is the second side S2. The first side S1 and the second side S2 are located on the main control board 101, and the first side S1 and the second side S2 are opposite to each other.

[0070] It should be noted that, in actual use, the main control board 101 can be installed in the first position or the second position.

[0071] Furthermore, in the embodiment of the present application, the main control board 101 also includes a plurality of interconnected power connectors.

[0072] Figure 4A A schematic diagram of the structure of another server provided in an embodiment of the present application. Figure 4A As shown, the power connector includes a power connector A on the third side and a power connector B on the fourth side. When the main control board 101 is located at the first position, as shown in FIG. Figure 4A As shown, the power connector A is connected to the power supply 401. When the main control board 101 is located at the second position, as shown in FIG. Figure 4B As shown, the power connector B is connected to the power source 401. Figure 4B This is a structural diagram of another server provided by an embodiment of the present application. Thus, when the main control board is located at different positions, the connection between the power supply and the power connector ensures the normal operation of the main control board.

[0073] It should be noted that the first side portion and the third side portion may be the same or different, and the second side portion and the fourth side portion may be the same or different, which is not specifically limited in the embodiment of the present application.

[0074] Need to explain, Figure 4A The number of two power connectors shown is for illustrative purposes only. In actual use, the number can be adjusted as needed, for example, to four, etc., and the embodiments of the present application do not specifically limit this.

[0075] A copper busbar may be used to interconnect the power connector A and the power connector B. The copper busbar may be cut and bent according to actual needs to adapt to the layout and space limitations inside different servers, and the number of power connectors may be easily increased or decreased through copper busbar interconnection, thereby improving the scalability of the server main control board 101.

[0076] Furthermore, the power connector A and the power connector B are interconnected by an L-shaped copper busbar.

[0077] In addition, the power connectors may be interconnected by flexible flat cables or multi-core cables, etc. The embodiment of the present application does not specifically limit the method of interconnecting the power connectors.

[0078] In the embodiment of the present application, the processor 101-4 and the memory 101-3 are adjacent, and can be located in the middle area of ​​the main control board 101, or in other areas, such as the peripheral area, which is not specifically limited in the embodiment of the present application. The processor 101-4 and the memory 101-3 are adjacent, which helps to make the signal path between the memory and the processor as short as possible. The short signal path helps to reduce the delay of signal transmission, improve the memory access speed and the performance of the overall server. It is also easier to design and implement centralized heat dissipation.

[0079] Furthermore, the server further includes an expansion board, which is used to expand the functions of the server. The expansion board is arranged between the main control board and the expansion module, and the BMC 106 is arranged on the expansion board. In addition, the expansion board further includes a third signal connector, the main control board includes a fourth signal connector, the third signal connector is connected to the fourth signal connector, and the third signal connector is connected to the baseboard management controller, thereby realizing communication signals between the baseboard management controller and the components on the main control board and the components on the fan board.

[0080] Attached Figure 4C A schematic diagram of the structure of another server provided in an embodiment of the present application.

[0081] The server further includes an expansion board 501. The main control board 101 further includes a fourth signal connector 501-2. The expansion board 501 is provided with a third signal connector 501-1. The BMC 106 is located on the expansion board 501.

[0082] In the embodiment of the present application, the fourth signal connector 501 - 2 is connected to the third signal connector 501 - 1 , and the third signal connector 501 - 1 is connected to the BMC 106 .

[0083] The fourth signal connector 501 - 2 is used to transmit communication signals between the BMC 106 and components on the main board and components on the fan board.

[0084] Exemplarily, the fourth signal connector can send the operation information of other devices on the main control board to BMC 106, and can also receive the management signal sent by BMC 106 to adjust the operation of other devices. The operation information of other devices includes the operation temperature, operation voltage, and operation current of processor 101-4.

[0085] For example, the fourth signal connector can directly collect the operation information collected by the temperature sensor, wind speed sensor and other collection devices on the fan board, and send the operation information to the BMC 106. The BMC 106 sends a collection instruction to the collection device on the fan board through the fourth signal connector.

[0086] Furthermore, the main control board 101 further includes a second logic device, wherein the second logic device is connected to the fourth signal connector, thereby sending the operation information of the device on the main board to the baseboard management controller, and receiving the control information sent by the baseboard management controller to control the operation of the device on the main control board.

[0087] It should be noted that the BMC may be located on the expansion board or not, which is not specifically limited in the embodiments of the present application.

[0088] In the embodiment of the present application, the server can adjust the installation position of the main control board as needed. For example, when the memory of the server needs to be expanded, the main control board is installed in the first position so that the side with more high-speed connectors is connected to the hard disk. When the network speed needs to be increased, the main control board is installed in the second position so that the side with more high-speed connectors is connected to the network card module. Therefore, by adjusting the main control board of the server, it is possible to flexibly adapt to the needs of different business configurations, deployments, and applications without modifying the processor.

[0089] In summary, the server provided by the embodiment of the present application is divided into a main control board, a fan board, a hard disk module and an expansion module, wherein the main control board includes a processor, a memory, a high-speed connector and a signal connector, and the fan board includes a fan and a second signal connector. Thus, the core components such as the processor, the memory and the high-speed connector are decoupled from other components. And when it is necessary to configure more hard disk modules when the storage capacity of the server needs to be expanded, the main control board is installed in the first position at this time, so that the side with a large number of high-speed connectors is connected to the hard disk. When more or stronger expansion functions are needed, the main control board is installed in the second position, so that the side with a large number of high-speed connectors is connected to the network card. Thus, by adjusting the installation position of the main control board of the server, it is not necessary to modify the position of the high-speed connector on the main control board, and it is possible to flexibly adapt to the needs of different business configurations, deployments and applications. In addition, when the main control board is rotated, the embodiment of the present application can reduce the impact on other links.

[0090] Embodiment 2

[0091] In an embodiment of the present application, the expansion board may also integrate a power connector, and may also integrate multiple signal connectors, each signal connector being connected to an expansion device, which is described in detail below in conjunction with the accompanying drawings.

[0092] For ease of explanation, in the embodiment of the present application, the main control board 101 includes 2 processors and 3 memories, and the main control board 101 also integrates 2 power connectors, a first high-speed connector group and a second high-speed connector group, the first high-speed connector group includes 4 high-speed connectors, the second high-speed connector group includes 8 high-speed connectors, and also includes 3 signal connectors (also called signal connectors) as an example for explanation. The expansion module is schematically illustrated by taking the network card module as an example. Among them, it is illustrated by taking the example that the first position needs to be switched to the second position by 180°.

[0093] Attached Figure 5 A schematic diagram of the structure of another server provided in an embodiment of the present application. Figure 5 The main control board 101 is shown in a first position.

[0094] In the embodiment of the present application, the server 100 includes a main control board 101, an expansion board 502, a fan board 104, a hard disk module 102 and an expansion module.

[0095] The main control board 101 includes a rotatable substrate 201, a power connector, a high-speed connector, a signal connector, a processor 101-4, and a memory 101-3. The power connector, the high-speed connector, the signal connector, the processor 101-4, and the memory 101-3 are all located on the rotatable substrate 201. The rotatable substrate 201 is a substrate with a central symmetrical structure and can rotate around the center.

[0096] Need to explain, Figure 5 The rotatable substrate is shown as a rectangle for schematic illustration only and can be adjusted as needed in actual use. Thus, when the rotatable substrate 201 rotates, the power connector, high-speed connector, signal connector, processor 101-4 and memory 101-3 can be driven to rotate synchronously.

[0097] In order to better utilize the space of the rotatable substrate and disperse the heat source, the memory 101-3 and the processor 101-4 are placed alternately. In addition, the memory 101-3 and the processor 101-4 are placed alternately to make the signal path between the memory and the processor as short as possible. The short signal path helps to reduce the delay of signal transmission, improve the memory access speed and the overall server performance. It is also easier to design and implement centralized heat dissipation.

[0098] The rotatable base plate 201 is also provided with a signal connector K1 (i.e., a first signal connector) and a signal connector K2 (i.e., a fourth signal connector). The signal connector K1 is connected to the signal connector (i.e., a second signal connector) of the fan board 104 through an extension cable X1, and is used to realize the connection between the main control board 101 and the fan board 104. Through the signal connector, the fan board 104 can receive a signal sent by a device on the main control board 101, specifically a management signal of the fan 503, such as adjusting the rotation speed of the fan 503.

[0099] The signal connector K2 is connected to the signal connector (i.e., the third signal connector) of the expansion board through the extension cable X1, and is connected to the BMC 106 through the signal connector on the expansion board. At this time, the main control board 101 can realize communication with the BMC 106. For example, the main control board 101 sends information of other components on the main board, such as the operating environment information of the processor, and information of components on the fan to the BMC 106. In addition, the BMC 106 can also send management information of the components to the main control board 101 to manage the components on the main control board 101 and the components of the fan.

[0100] Exemplarily, the main control board 101 receives the fan management information sent by the BMC 106, and sends it to the fan board through the signal connector K1 and the extension cable X1, and the signal connector of the fan board 104, so as to manage the fan. The main control board 101 can receive the fan operation information sent by the fan board 104 through the signal connector K1 and the extension cable X1, and the signal connector of the fan board 104, and send the fan operation information to the BMC 106 through the signal connector K2, the extension cable X1 and the signal connector of the extension board.

[0101] In the embodiment of the present application, the expansion board 502 may have multiple signal connectors, and the main control board 101 includes multiple signal connectors adjacent to the signal connectors of the expansion board 502. Thus, the main control board 101 can add expansion modules through the multiple signal connectors on the expansion board 502.

[0102] For example, Figure 5 Two signal connectors K2 are shown, one of which is connected to the BMC 106 and the other is connected to other expansion modules. The main control board 101 supports connection with multiple expansion boards by deploying multiple signal connectors, thereby increasing the scalability and flexibility of the server 100 and enabling it to adapt to a variety of application scenarios.

[0103] In the embodiment of the present application, the top surface of the main control board 101 includes a middle area P0 and two peripheral areas surrounding the middle area, and the two peripheral areas are respectively a first side P1 and a second side P2. Multiple processors 101-4 and multiple memories 101-3 are located in the middle area P0 of the main control board 101. This design can ensure that the signal path between the processor and memory components and other devices is as short as possible. The short signal path helps to reduce the delay of signal transmission, improve the memory access speed and the performance of the overall server. It is also easier to design and implement centralized heat dissipation.

[0104] The first side portion P1 is located at a first side of the main control board 101, and the second side portion P2 is located at a third side M3 of the main control board 101. The first side and the third side M3 are opposite sides.

[0105] The first high-speed connector group includes 4 high-speed connectors C2, which are located on the first side P1. The second high-speed connector group includes 8 high-speed connectors C1, which are located on the second side P2, the power connector A is located on the third side, and the power connector B is located on the fourth side. The third side is the first vertex position of the first side P1, the second side is located at the second vertex position of the second side, and the first vertex and the second vertex are opposite vertex angles.

[0106] There are three power connectors in the server, including power connector A, power connector B, and power connector C. Figure 5 The power connector A shown in the figure is close to the power connector C of the expansion board, and the power connector C of the expansion board is connected to the power supply. The power connector A and the power connector B are interconnected by an L-shaped copper bus 504. The power connector A is close to the power connector C of the expansion board. The power connector A is interconnected with the power connector C copper bus 504.

[0107] Thus, when the rotatable substrate 201 rotates 180°, the power connector B is interconnected with the power connector C copper bus 504. That is, the power connector C on the expansion board and the power connector A or B on the main control board can be interconnected at will to achieve unified power supply. And the L-shaped copper bus 504 interconnection method can reduce mechanical stress and avoid damage to the power connector. In addition, the L-shaped copper bus 504 interconnection method can effectively disperse the current and improve system stability.

[0108] The signal connector K1 is located at the first side P1 of the rotatable main board 201, close to the fourth side M4, and the signal connector K2 is located at the second side P3 of the rotatable main board 201, close to the third side M3. In the embodiment of the present application, when the rotatable main board 201 rotates, the signal connector K1 is still connected to the signal connector of the fan board 104, and the signal connector K2 is still connected to the signal connector of the expansion board 502. At this time, the length of the extension cable X1 needs to be adjusted.

[0109] Further, the high-speed connector C2 is located at the first side P1, wherein the rotatable mainboard 201 is connected to the hard disk module 102 through the high-speed connector C2 and the high-speed cable XH1. The high-speed connector C1 is located at the second side P2. The main control board 101 is connected to the network card module through the high-speed connector C1 and the high-speed cable XH2.

[0110] For example, if each high-speed connector can achieve 1x high-speed bandwidth, 8 high-speed connectors C1 can be connected to multiple network cards to achieve high-speed connection between the processor and the network card, and the external network interface of the entire server can achieve 8x bandwidth as a whole. 4 high-speed connectors C2 are connected to the hard disk to achieve the connection function between the processor and the hard disk, and the storage function of the entire server is realized, and the overall storage interface achieves 4x bandwidth.

[0111] In the embodiment of the present application, the expansion module includes a BMC 106, a power supply 505 and a network card module.

[0112] The expansion module includes a first sub-expansion module and a second sub-expansion module, wherein the first sub-expansion module is located on top of the second sub-expansion module. For the first sub-expansion module located at the top, the main control board 101 can be directly connected to the first sub-expansion module through a cable. For the second sub-expansion module located at the bottom, the main control board 101 is connected to the second sub-expansion module through the expansion board 502.

[0113] For example, Figure 5 As shown, the first sub-expansion module includes four upper network card modules 103-1. The main control board 101 is connected to the four upper network card modules 103-1 through four high-speed connectors C2 in the second high-speed connector group and high-speed cables XH1 corresponding to each high-speed connector C2.

[0114] The second sub-expansion module includes a first lower network card module 103-3, a second lower network card module 103-4, a BMC 106 and a power module 105. The remaining two high-speed connectors in the second high-speed connector group are connected to the two high-speed connectors in the expansion board, and the two high-speed connectors in the expansion board are respectively connected to the first lower network card module 103-3 and the second lower network card module 103-4.

[0115] Need to explain, Figure 5 The high-speed connectors C1 shown are arranged in parallel on the first side P1 and are at the same distance from the first edge, and the high-speed connectors C2 are arranged in parallel on the second side P2 and are at the same distance from the third edge M3. This is only a schematic representation and can be adjusted as needed in actual use.

[0116] Thus, the high-speed connector C1 and the high-speed connector C2 are located at the first side P1 and the second side P2, respectively, which can ensure that the signal path between them and the corresponding devices (hard disk and network card) is as short as possible. The short signal path reduces the risk of signal reflection, crosstalk and attenuation, and improves the integrity and stability of the signal. The high-speed connector C1 and the high-speed connector C2 are arranged in parallel in their respective areas and at the same distance from the edge, which helps to ensure the neatness and consistency of the signal lines and reduce mutual interference between signals. The high-speed connectors arranged in parallel can simplify PCB wiring and reduce wiring conflicts and complexity.

[0117] In one example, the main control board 101 further includes a heat sink (not shown in the figure), which is located above the processor 101-4 and fits tightly to the processor 202. A heat conduction component, such as thermal grease, is usually applied between them to ensure good heat conduction characteristics. It should be noted that the top of the processor 101-4 refers to the side away from the rotatable part 201. Therefore, the heat sink rotates with the processor 101-4.

[0118] It should be noted that a heat sink is arranged above one processor 101 - 4 . A heat sink is arranged above each processor 101 - 4 in the plurality of processors 101 - 4 to ensure heat dissipation performance.

[0119] Furthermore, the relative distance between the heat sink and each side of the processor 101 - 4 is equal, that is, the heat sink is located at the exact center above the processor, thereby ensuring heat dissipation consistency.

[0120] Furthermore, the cable outlet directions of the high-speed cable XH1 and the high-speed cable XH2 are different from the direction perpendicular to the rotatable mainboard 201 , so that when the rotatable mainboard 201 rotates, the cable outlet modes remain consistent.

[0121] For attachment Figure 5 As shown, when the rotatable substrate rotates 180°, the attached Figure 6 Attached Figure 6 This is a schematic diagram of the structure of another server main control board provided in an embodiment of the present application. The first side portion P1 and the second side portion P2 of the server main control board are interchanged.

[0122] At this time, the power connector B is connected to the power connector C. The high-speed connector C1 is connected to the hard disk through the high-speed cable XH1, and the high-speed connector C2 is connected to the network card through the high-speed cable XH2. At this time, the four high-speed connectors C2 on the first side are connected to the four network cards through the high-speed cable XH1. The overall network interface achieves 4 times the bandwidth. The eight high-speed connectors A in the third area are connected to the hard disk through the high-speed cable XH2, and the overall storage interface achieves 8 times the bandwidth. That is, at this time, the server main control board 101 changes the number of high-speed interfaces connected to the hard disk and the number of high-speed interfaces connected to the network card.

[0123] In summary, the server provided in the embodiment of the present application realizes the rotation of the rotatable substrate by setting a rotatable substrate, and fixing the processor, memory, high-speed connector and power connector, and fixing the signal connector on the rotatable substrate, so as to drive the processor, memory, high-speed connector and power connector to rotate synchronously. By setting multiple high-speed connectors, and multiple high-speed connectors are located on opposite sides, and the number of high-speed connectors on each side is different, it is realized that when the rotatable main control board rotates in the first position and the second position, the number of high-speed connectors connecting the hard disk module and the expansion module is adjusted to adapt to different scenarios, so as to adapt to diversified design requirements and improve design flexibility. And by setting two power connectors on the main control board, and the two power connectors are located at the top angle position, when the rotatable main control board rotates 180°, with fewer power connectors, the connection between the power supply and the power connector can still be realized, and the normal operation of the main control board can be ensured. Further, the embodiment of the present application decouples the core components such as the processor, memory, the high-speed connector and the power connector connected to the processor from other components, so that when the rotatable substrate rotates, the impact on other links can be reduced.
