[0026] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0027] In this application, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this application.

[0028] To address the issue of poor transmission efficiency of server motherboards in related technologies, this embodiment provides a server motherboard and a server.

[0029] Example 1

[0030] As shown in Figures 1 and 2, a server motherboard includes a board body 10, a connection interface 20, and an onboard data interface 40. The board body 10 has a first side 11 and a second side 12 that are disposed opposite to each other. The connection interface 20 is connected to the board body 10 and is located on the first side 11 of the board body 10. The connection interface 20 includes at least one of a power supply interface and a fan terminal interface 21. The connector 30 is connected to the board body 10 and is located on the second side 12 of the board body 10. The connector 30 includes at least one of a multi-channel input / output interface 31, a power connector 32, and an external card connector 33. The onboard data interface 40 is connected to the board body 10.

[0031] In this embodiment, the board body 10 is configured with a first side 11 and a second side 12, and the first side 11 and the second side 12 are respectively provided with a connection interface 20 and a connector 30. This configuration is beneficial for the wiring of the server motherboard and the connection between various internal components of the server, thereby shortening the transmission path between each component and the server motherboard, thus improving data transmission efficiency. Moreover, it enables the server motherboard to make more effective use of space, thereby reducing the space occupied by the server motherboard and thus reducing the cost of the server motherboard.

[0032] In this embodiment, the connection interface 20 includes a power supply interface and a fan terminal interface 21. Considering that the connection interfaces 20 are all connected to external devices, they are located at the edge of the first side 11 to facilitate connection between the interface 20 and external devices, thereby simplifying fan insertion and removal and power cable management, and optimizing the layout and wiring of the server motherboard. The power supply interface and fan terminal interface 21 are arranged along the extension direction of the first side 11. The number of connection interfaces 20 can be set as needed; both the power supply interface and the fan terminal interface 21 can be one or more. By placing the power supply interface and fan terminal interface 21 on the first side 11, power and heat dissipation support can be provided to the server more directly, thereby improving the overall stability and operating efficiency of the server.

[0033] As shown in Figure 1, the onboard data interface 40 is located between the first side 11 and the second side 12 of the board body 10. The onboard data interface 40 is further away from the first side 11 than the connection interface 20, and multiple onboard data interfaces 40 are arranged along the extension direction of the second side 12. This arrangement of the onboard data interface 40 in the middle of the board body 10 reduces the data transmission path between the onboard data interface 40 and the chips on the server motherboard, thereby ensuring the stability of data transmission and improving data transmission efficiency. Furthermore, it prevents the onboard data interface 40 from occupying additional space outside the board body 10, thus optimizing the space utilization of the board body 10, making the server motherboard structure more compact, improving the deployment efficiency and resource utilization of the server motherboard, and allowing the position of the onboard data interface 40 on the surface of the board body 10 to be adjusted according to actual needs, thereby improving the flexibility of the server motherboard and facilitating adaptation to different server architectures.

[0034] It should be noted that in this embodiment, the first side 11 and the second side 12 both refer to areas of a certain size near the edge of the plate 10, and not just to a certain edge line of the plate 10; the edge of the first side 11 refers to the edge of the first side 11 away from the second side 12, and similarly, the edge of the second side 12 refers to the edge of the second side 12 away from the first side 11, and the edges of the first side 11 and the second side 12 are arranged opposite to each other. The extension direction of the first side 11 refers to the direction perpendicular to the arrangement direction of the first side 11 and the second side 12, and is also the extension direction of the second side 12.

[0035] In this embodiment, connector 30 includes a multi-channel input / output interface 31, a power connector 32, and an external card connector 33. All three are located on the second side 12, facilitating direct connection between the server motherboard and external cards, power supplies, and other components. Compared to cable connections, this method shortens the transmission path between the server motherboard and other components, thus improving the transmission efficiency of the server motherboard. The external card connector 33 is closer to the edge of the second side 12 than the multi-channel input / output interface 31, and in this embodiment, it is located at the edge of the second side 12. This makes the installation and removal of external cards more convenient, allowing operators to perform maintenance without opening the server chassis cover. This facilitates quick and easy hardware replacement and upgrades, while also reducing the space occupied by external cards in the central area of ​​the board 10, providing more space for other critical components.

[0036] In this embodiment, the external card connector 33 includes an Open Compute Project (OCP) card connector and an input / output connector. Multiple OCP card connectors are provided, offering more expansion options for the server motherboard and meeting the hardware performance and functional requirements of different server applications, thereby significantly improving the server's computing power and data processing efficiency. As shown in Figure 2, this embodiment has three external card connectors 33. Considering that the server in this embodiment has two OCP cards, two OCP card connectors are provided, allowing all OCP cards to be directly connected to the server motherboard, facilitating maintenance by operators. Of course, depending on actual needs, when the server has three OCP cards, all three external card connectors 33 can be configured as OCP card connectors, or when there is a requirement for three input / output connectors, all three external card connectors 33 can be configured as input / output connectors, while other OCP cards and input / output connectors that cannot be connected to the external card connectors 33 can be connected to the server motherboard via cables.

[0037] It should be noted that the multi-channel input / output interface 31 is also known as the MCIO interface. The MCIO interface enhances the communication and data processing capabilities between systems by providing high-speed memory access and control functions, thereby enabling more efficient data management and processing capabilities. The Open Compute Project card connector, also known as the OCP card connector, is an interface under the Open Compute Project standard. The design of the Open Compute Project card connector takes into account high bandwidth and low latency data transmission, supports high-speed data exchange, meets the data center's demand for high-speed network connectivity, and supports modular hardware design, facilitating equipment upgrades and expansions, improving deployment efficiency and maintenance convenience, and helping data centers achieve higher energy efficiency, flexibility, and cost-effectiveness. The input / output connector is the management IO card connector, used to connect management IO cards. Management IO cards refer to interface cards used to realize remote management and monitoring functions, which can improve the manageability and maintainability of servers. Through management IO cards, administrators can quickly respond to server failures, perform remote troubleshooting and system recovery, reduce the need for on-site maintenance, and save time and costs.

[0038] In this embodiment, the edge of the second side 12 of the board 10 includes a first segment 121 and a second segment 122 opposite to the first side 11. The distance between the first segment 121 and the edge of the first side 11 is greater than the distance between the second segment 122 and the edge of the first side 11. The multi-channel input / output interface 31 and the external card connector 33 are located in the first segment 121, and the power connector 32 is located in the second segment 122. This can better balance the heat source distribution on the server motherboard and improve heat dissipation efficiency. At the same time, the independent setting of the power connector 32 can reduce the interference of power lines to signal lines.

[0039] Specifically, in this embodiment, the board body 10 is configured as a rectangle with a notch at the side edge of the second side 12, so that the edge at the notch is the second segment 122, and the edges of the other parts of the second side 12 are the first segment 121. Each end of the second side 12 has a side edge, and the notch can be located at either side edge for ease of wiring. Along the arrangement direction of the second side 12 and the first side 11, the external card connector 33 and the multi-channel input / output interface 31 are sequentially arranged at the first segment 121, with the three external card connectors 33 arranged sequentially along the extension direction of the second side 12, and the two multi-channel input / output interfaces 31 arranged sequentially along the extension direction of the second side 12. The power connector 32 is located in the second segment 122. On one hand, this allows the power supply, after being connected to the power connector 32, to fill the gap, thus forming a nearly complete rectangle with the board 10, fitting the rectangular installation space of the server chassis and reducing the space occupied by the server motherboard. On the other hand, the gap is located at the side edge of the second side 12, allowing the power supply and power connector 32 to be positioned at the edge of the board 10, which facilitates heat dissipation and minimizes the impact of power supply heat on other components. This embodiment provides two power connectors 32, arranged along the extension direction of the second side 12. Of course, the size of the gap can be adjusted according to the size of the power supply; the number of power connectors 32 can also be adjusted according to the power requirements of the server motherboard. Thus, by placing the multi-channel input / output interface 31 and the external card connector 33 in the first segment 121, and the power connector 32 in the second segment 122, signal transmission quality can be guaranteed while optimizing the heat dissipation path and saving space occupied by the server motherboard.

[0040] This application also provides a server, including the aforementioned server motherboard. The layout of the various connection interfaces 20 and connectors 30 shortens the data transmission path between the various devices and the server motherboard, simplifies the wiring of the server motherboard, and makes fuller and more efficient use of the server motherboard space. This improves the data transmission quality between the various devices in the server, thereby improving the server's hardware performance and heat dissipation efficiency, ensuring the stable operation of the server under high load, and thus improving the availability and reliability of the server.

[0041] In this embodiment, the server also includes a fan, which is disposed on the first side 11 of the server motherboard. The fan's projection onto the server motherboard at least partially overlaps with the motherboard, thereby enabling more effective and rapid heat dissipation from the server motherboard. Specifically, in this embodiment, the fan terminal interface 21 faces away from the surface of the board 10, so that the fan, fan terminal interface 21, and board 10 are arranged sequentially in a direction perpendicular to the surface of the board 10. That is, the connection between the fan and the fan terminal interface 21 is a top-to-bottom plug-in connection, with the fan terminal interface 21 located directly below the fan terminal, which facilitates hot-swapping of the fan and improves server maintenance efficiency. As shown in Figure 1, this embodiment has multiple fan terminal interfaces 21, arranged along the extension direction of the first side 11. After the fan is connected to the fan terminal, it is also arranged along the extension direction of the first side 11. Thus, the fan's airflow direction follows the arrangement direction of the first side 11 and the second side 12, ensuring that heat is rapidly dissipated from the central area of ​​the server motherboard, avoiding overheating caused by heat accumulation, and thus more effectively cooling the server motherboard.

[0042] Example 2

[0043] Unlike Embodiment 1, the fan in this embodiment is connected to the server motherboard in a different way. In Embodiment 1, the fan and the fan terminal interface 21 of the server motherboard are connected by plugging and unplugging. However, in this embodiment, the fan is not directly connected to the server motherboard. Instead, it is connected to the server motherboard by setting up a fan board, thereby improving the reusability of the server motherboard. Correspondingly, the connection interface 20 located on the first side 11 of the board body 10 may not be provided with a fan terminal interface 21, but with a fan board interface to achieve connection with the fan board.

[0044] In this embodiment, the server also includes a fan and a fan board. The fan is mounted on the fan board, and the fan board is electrically connected to the connection interface 20 of the server motherboard. This improves the convenience of fan installation and maintenance, and allows for flexible adjustment according to the actual heat dissipation needs of the server without altering the structure of the server motherboard, thus enhancing its reusability. Specifically, the connection interface 20 in this embodiment includes a power supply interface and a fan board interface. The fan board interface connects to the fan board, and the fan board has a connection interface for the fan terminals, eliminating the need for a fan terminal interface 21 on the server motherboard. This allows for flexible adjustment of the fan board's size and shape based on the server's heat dissipation requirements and fan specifications. The fan's position can also be adjusted by changing the fan board according to the location of the heat source, increasing flexibility. Furthermore, the maintainability and upgradeability of the fan board mean that even if heat dissipation requirements change, the server motherboard does not need to be disassembled or replaced; only the fan board and fan need to be adjusted accordingly, improving the server motherboard's adaptability and extending its lifespan.

[0045] In this embodiment, the fan plate can be arranged adjacent to the first side 11 to reduce the space occupied by the fan plate after it is connected to the server motherboard. When the server chassis has a large space, in order to prevent the fan plate from shaking inside the server chassis after it is connected to the server motherboard, the fan plate can also be arranged adjacent to the server motherboard at the fan plate interface, and the other positions of the fan plate can be spaced apart from the server motherboard to adapt to different server chassis.

[0046] Example 3

[0047] Unlike Embodiment 1, this embodiment features a different location for the onboard data interface 40 and a different number of external card connectors 33 to meet the varying connection requirements of the server. Furthermore, this embodiment includes a cable management unit 50 to further optimize the server motherboard cabling. In Embodiment 1, the onboard data interface 40 is located between the first side 11 and the second side 12, and three external card connectors 33 are provided, including one input / output connector and two Open Compute Project Card connectors. In this embodiment, the onboard data interface 40 is located on the first side 11, and two external card connectors 33 are provided, including one input / output connector and one Open Compute Project Card connector.

[0048] As shown in Figures 3 and 4, in this embodiment, the connection interface 20 includes a power supply interface and a fan terminal interface 21. The onboard data interface 40 is located on the first side 11, which facilitates the connection between the hard drive and the onboard data interface 40, and facilitates the wiring and layout of the server motherboard. Specifically, in this embodiment, the fan terminal interface 21 is located at the edge of the first side 11 and is arranged along the extension direction of the first side 11. The onboard data interface 40 is located away from the edge of the first side 11 relative to the connection interface 20, and is also arranged along the extension direction of the first side 11. The number of onboard data interfaces 40 can be adjusted according to actual needs. In this way, the power supply interface, fan terminal interface 21, and onboard data interface 40 are all arranged on the first side 11. When the hard drive is placed near the first side 11, this arrangement is beneficial for the cable connection between the hard drive backplane and the server motherboard. Thus, the hard drive interface connected to the backplane can also be located near the first side 11, which facilitates the docking with the hard drive and simplifies the wiring of the server motherboard.

[0049] In this embodiment, multiple power supply interfaces and fan terminal interfaces 21 are provided to directly provide power and heat dissipation support to the server. Of course, the number of power supply interfaces and fan terminal interfaces 21 is not fixed and can be adjusted according to actual needs to meet the server's power and heat dissipation requirements. When the server has more flexible heat dissipation needs, the fan terminal interface 21 can be set as a fan board interface, with a separate fan board for the server. The fan board connects directly to the fan terminal interface 21, and the fan connects directly to the fan board. This eliminates the need for frequent disassembly and adjustment of the server motherboard when heat dissipation requirements change, thereby improving the reusability of the server motherboard.

[0050] In this embodiment, connector 30 includes a multi-channel input / output interface 31, a power connector 32, and an external card connector 33. All three are located on the second side 12, facilitating direct connection between the server motherboard and external cards, power supplies, and other components. Compared to cable connections, this method shortens the transmission path between the server motherboard and other components, thus improving the transmission efficiency of the server motherboard. The external card connector 33 is closer to the edge of the second side 12 than the multi-channel input / output interface 31, and in this embodiment, it is located at the edge of the second side 12. This makes the installation and removal of external cards more convenient, allowing operators to perform maintenance without opening the server chassis cover. This facilitates quick and easy hardware replacement and upgrades, while also reducing the space occupied by external cards in the central area of ​​the board 10, providing more space for other critical components.

[0051] In this embodiment, the external card connector 33 includes an Open Compute Project Card connector and an Input / Output connector. There is only one Open Compute Project Card connector, thereby improving the expansion capabilities of the server motherboard. Specifically, as shown in Figures 3 and 4, in this embodiment, the external card connector 33 is located in the first segment 121, and there are two of them. One is an Open Compute Project Card connector, and the other is an Input / Output connector. The Open Compute Project Card connector is used to connect the Open Compute Project Card, and the Input / Output connector is used to connect the Management I / O Card. Thus, one Open Compute Project Card and one Management I / O Card can be connected through the external card connector 33, thereby improving the signal transmission efficiency of the Open Compute Project Card and the Management I / O Card. Furthermore, the structure is compact, reducing the space occupied on the server motherboard and saving motherboard costs. Of course, depending on actual needs, both external card connectors 33 can be set as Open Compute Project Card connectors, or both external card connectors 33 can be set as Input / Output connectors.

[0052] It should be noted that the server in this embodiment includes two open computing project cards and two management I / O cards. Considering the limited space at the edge of the second side 12 of the board 10, only two external card connectors 33 are provided. Thus, one open computing project card is connected to the external card connector 33, and the other open computing project card can be connected to the server motherboard via an external cable; one management I / O card is connected to the input / output connector, and the other can be connected to the server motherboard via an external cable. This not only improves the scalability and compatibility of the server motherboard, but also enhances the signal transmission quality of some open computing project cards and management I / O cards, while making full use of the space at the edge of the second side 12 of the board 10.

[0053] As shown in Figure 3, in this embodiment, the server motherboard also has a cable management unit 50, which is located in the middle area of ​​the board body 10. Cables are routed through the cable management unit 50, thereby optimizing cable management, reducing the impact of cables on motherboard heat dissipation, improving the tidiness of the server's internal structure, and facilitating maintenance and troubleshooting. Specifically, considering the space between the memory modules on the server motherboard, the cable management unit 50 in this embodiment can be located between the memory modules, allowing some cables to be routed from the server motherboard, thus saving cable length and costs. The length direction of the cable management unit 50 is along the arrangement direction of the first side 11 and the second side 12. The cable management unit 50 has a base plate and two oppositely arranged side plates. The base plate is connected to the board body 10, and both side plates are connected to the base plate and are arranged perpendicular to the base plate, thereby forming a rectangular cable management space. Multiple protrusions are provided on the ends of both side panels away from the base plate, and these protrusions extend towards each other to obstruct the cable management space. The protrusions on each side panel are arranged along the length of the cable organizer 50, and the protrusions on the two side panels are staggered. This facilitates the entry of cables into the cable management space for overall cable organization while preventing cables from easily detaching from it. This cable management system not only keeps the server motherboard and internal components tidy and reduces the impact of cable clutter on signals, but also allows maintenance personnel to quickly locate and resolve cable-related issues, thereby improving operational efficiency and reducing maintenance costs. Of course, the cable organizer 50 can also be placed in other available positions on the board 10, or it can be configured in other shapes, as long as it meets the cable management requirements of the server motherboard and does not interfere with other components on the server motherboard.

[0054] In this embodiment, the server also includes a fan and a hard drive, both externally mounted on the first side 11 of the server motherboard. The fan is electrically connected to the connection interface 20 of the first side 11, and the hard drive is electrically connected to the onboard data interface 40, thereby improving the server's heat dissipation performance and the hard drive's data transfer speed. Specifically, in this embodiment, the fan is electrically connected to the fan terminal interface 21, and multiple fan terminal interfaces 21 are provided along the extension direction of the first side 11. The fan is also located near the first side 11, making the connection between the fan and the fan terminal interface 21 more convenient and quick. This allows the server to easily and quickly install multiple fans to dissipate heat from high-heat-generating components inside the server, thereby improving server stability and extending hardware lifespan. In this embodiment, multiple onboard data interfaces 40 are also provided. Compared to the hard drive being connected to the server motherboard via cables, the hard drive is externally mounted on the first side 11, close to the onboard data interface 40, allowing the hard drive to be directly electrically connected to the onboard data interface 40, thus providing higher signal transmission quality and improving server performance.

[0055] It should be noted that "multiple" in the above embodiments refers to at least two.

[0056] As can be seen from the above description, the embodiments of this application achieve the following technical effects:

[0057] 1. Solved the problem of poor transmission efficiency of server motherboards in related technologies;

[0058] 2. By setting the board to have a first side and a second side, and setting the first side and the second side to respectively set the connection interface and connector, this setting method is conducive to the wiring of the server motherboard and the connection between various components inside the server, thereby shortening the transmission path between each component and the server motherboard, and thus improving data transmission efficiency.

[0059] 3. This allows the server motherboard to utilize space more effectively, thereby reducing the space occupied by the server motherboard and thus lowering the cost of the server motherboard.

[0060] 4. Cables are placed within the cable management space, which not only keeps the server motherboard and internal parts of the server tidy and reduces the impact of messy cables on signals, but also makes it easier for maintenance personnel to quickly locate and handle cable-related problems, thereby improving operation and maintenance efficiency and reducing maintenance costs.
