[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0024] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0025] In order to solve the problem of poor transmission efficiency of a server mainboard in the related art, this embodiment provides a server mainboard and a server.

[0026] Embodiment 1

[0027] like Figure 1 , Figure 2 A server motherboard shown includes a board body 10, a connection interface 20 and an onboard data interface 40, wherein the board body 10 has a first side 11 and a second side 12 that are arranged 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, and the connection interface 20 includes at least one of a power supply interface and a fan terminal interface 21; a connector 30, the connector 30 is connected to the board body 10 and is located on the second side 12 of the board body 10, and the connector 30 includes at least one of a multi-channel input and output interface 31, a power connector 32, and an external card connector 33; and the onboard data interface 40 is connected to the board body 10.

[0028] In this embodiment, the board body 10 has a first side 11 and a second side 12 relative to each other, and the first side 11 and the second side 12 are respectively provided with a connection interface 20 and a connector 30. This arrangement is beneficial to the wiring of the server mainboard and the connection between various components inside the server, thereby shortening the transmission path between each component and the server mainboard, thereby improving data transmission efficiency, and enabling the server mainboard to use space more effectively, thereby helping to reduce the space occupied by the server mainboard, thereby reducing the cost of the server mainboard.

[0029] In the present embodiment, the connection interface 20 includes a power supply interface and a fan terminal interface 21. Considering that the connection interface 20 is connected to an external device, the connection interface 20 is arranged at the edge of the first side 11 to facilitate the connection between the connection interface 20 and the external device, thereby facilitating the plugging and unplugging of the fan and the combing of the power cord, thereby optimizing the layout and wiring of the server motherboard. The power supply interface and the fan terminal interface 21 are arranged along the extension direction of the first side 11, and the number of the connection interface 20 can be set as needed, and the number of the power supply interface and the fan terminal interface 21 can be set to one or more. In this way, setting the power supply interface and the fan terminal interface 21 on the first side 11 can provide power and heat dissipation support for the server more directly, thereby improving the overall stability and operation efficiency of the server.

[0030] like Figure 1 As shown, 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 farther away from the first side 11 than the connection interface 20, and is provided in a plurality and arranged along the extension direction of the second side 12. This way of arranging the onboard data interface 40 in the middle position of the board body 10, on the one hand, reduces the data transmission path between the onboard data interface 40 and the chip on the server mainboard, thereby ensuring the stability of the data transmission of the onboard data interface 40 and improving the data transmission efficiency. On the other hand, the onboard data interface 40 does not occupy additional space outside the board body 10, thereby optimizing the space utilization of the board body 10, making the structure of the server mainboard more compact, and improving the deployment efficiency and resource utilization of the server mainboard. Moreover, the setting position of the onboard data interface 40 on the surface of the board body 10 can be adjusted according to actual needs, thereby improving the flexibility of the server mainboard and facilitating the adaptation of different server architectures.

[0031] It should be noted that the first side 11 and the second side 12 of the present embodiment both refer to a region of a certain size close to the edge of the plate body 10, and do not only refer to a certain edge line of the plate body 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 edge of the first side 11 and the edge of the second side 12 are arranged oppositely. 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.

[0032] In this embodiment, the connector 30 includes a multi-channel input and output interface 31, a power connector 32 and an external card connector 33. The multi-channel input and output interface 31, the external card connector 33 and the power connector 32 are all located on the second side 12, so as to facilitate the direct connection between the server mainboard and other devices such as external cards and power supplies. Compared with the method of connecting through cables, this method is conducive to shortening the transmission path between the server mainboard and other devices, thereby facilitating the transmission efficiency of the server mainboard. Compared with the multi-channel input and output interface 31, the external card connector 33 is closer to the edge line of the second side 12, and the external card connector 33 of this embodiment is located at the edge of the second side 12, so that the installation and removal of the external card is more convenient, so that the operator does not need to open the cover of the server chassis for maintenance, so as to facilitate the operator to quickly and conveniently replace and upgrade the hardware, while reducing the occupation of the external card in the central area of ​​the board body 10, providing more space for other key components.

[0033] In this embodiment, the plug-in card connector 33 includes an open computing project card connector and an input / output connector. There are multiple open computing project card connectors, thereby providing more expansion options for the server motherboard, meeting the requirements of different server applications for hardware performance and functions, thereby significantly improving the computing power and data processing efficiency of the server. Figure 2 As shown, this embodiment is provided with three external card connectors 33. Considering that the server of this embodiment is provided with two open computing project cards, two open computing project card connectors are provided, so that all open computing project cards can be directly connected to the server motherboard, which is convenient for operators to maintain. Of course, according to actual needs, when the server is provided with three open computing project cards, the three external card connectors 33 can also be set as open computing project card connectors, or when there is a need for three input and output connectors, the three external card connectors 33 are all set as input and output connectors, and other open computing project cards and input and output connectors that cannot be connected to the external card connectors 33 can be connected to the server motherboard through cables.

[0034] It should be noted that the multi-channel input and output interface 31 is 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 computing project card connector is the OCP card connector, an interface under the Open Compute Project standard. The design of the open computing project card connector takes into account high-bandwidth and low-latency data transmission, and can support high-speed data exchange to meet the data center's demand for high-speed network connections. It also supports modular hardware design, facilitates equipment upgrades and expansions, improves deployment efficiency and maintenance convenience, and helps data centers achieve higher energy efficiency, flexibility and cost-effectiveness; the input and output connector is the management IO card connector, which is used to connect the management IO card. The management IO card refers to an interface card used to implement remote management and monitoring functions, which can improve the manageability and maintainability of the server. Through the management IO card, administrators can quickly respond to server failures, perform remote troubleshooting and system recovery, reduce the need for on-site maintenance, and save time and cost.

[0035] In this embodiment, the edge of the second side 12 of the board body 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 and 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. In this way, the heat source distribution on the server motherboard can be better balanced and the heat dissipation efficiency can be improved. At the same time, the independent setting of the power connector 32 can reduce the interference of the power line on the signal line.

[0036] Specifically, the board body 10 of this embodiment is set to be 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 other part of the edge of the second side 12 is the first segment 121. There is a side edge at each end of the second side 12, and the notch can be set at any one of the side edges according to the convenience 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 and output interface 31 are sequentially arranged at the first segment 121, and the three external card connectors 33 are sequentially arranged along the extension direction of the second side 12, and the two multi-channel input and output interfaces 31 are sequentially arranged along the extension direction of the second side 12. The power connector 32 is arranged in the second section 122. On the one hand, after the power supply is connected to the power connector 32, the gap can be filled, so that the power supply and the board body 10 as a whole form a nearly complete rectangle to adapt to the rectangular installation space of the server chassis, thereby 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, so that the power supply and the power connector 32 can be located at the edge of the board body 10, which is conducive to the heat dissipation of the power supply and at the same time, the influence of the power supply heating on other devices is avoided as much as possible. In this embodiment, two power connectors 32 are 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 demand of the server motherboard. In this way, by setting the multi-channel input and output interface 31 and the external card connector 33 in the first section 121, and the power connector 32 in the second section 122, it is possible to optimize the heat dissipation path while ensuring the signal transmission quality, and save the space occupied by the server motherboard.

[0037] The present application also provides a server, including the above-mentioned server motherboard, wherein the layout of each connection interface 20 and connector 30 shortens the data transmission path between each device and the server motherboard, simplifies the wiring of the server motherboard, and makes the space utilization of the server motherboard more full and efficient, thereby improving the data transmission quality between the various devices of the server, and further improving the hardware performance and heat dissipation efficiency of the server, thereby ensuring the stable operation of the server under high load, and further improving the availability and reliability of the server.

[0038] In the present embodiment, the server further includes a fan, which is disposed on the first side 11 of the server mainboard, and the orthographic projection of the fan on the server mainboard at least partially overlaps with the server mainboard, thereby being able to more effectively and rapidly discharge the heat generated by the server mainboard. Specifically, the fan terminal interface 21 of the present embodiment opens toward the side away from the surface of the board body 10, so that the fan, the fan terminal interface 21, and the board body 10 are sequentially arranged in a direction perpendicular to the surface of the board body 10, that is, the connection between the fan and the fan terminal interface 21 is an up-and-down plug-in connection, and the fan terminal interface 21 is directly located at the bottom of the fan terminal, which is conducive to realizing hot-swappable connection of the fan, thereby facilitating improving the maintenance efficiency of the server. Figure 1 As shown, in this embodiment, there are multiple fan terminal interfaces 21, and they are arranged along the extension direction of the first side 11, so that the fan is also arranged along the extension direction of the first side 11 after being connected to the fan terminal. In this way, the air outlet direction of the fan is along the arrangement direction of the first side 11 and the second side 12, thereby ensuring that heat is quickly discharged from the central area of ​​the server motherboard, avoiding overheating caused by heat accumulation, and thus more effectively realizing the heat dissipation of the server motherboard.

[0039] Embodiment 2

[0040] Different from the first embodiment, the connection method between the fan and the server mainboard of the present embodiment is different. The first embodiment adopts the method of connecting the fan and the fan terminal interface 21 of the server mainboard by plugging and unplugging, while the fan of the present embodiment is not directly connected to the server mainboard, but is connected to the server mainboard by setting a fan board, thereby improving the reusability of the server mainboard; accordingly, 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 a fan board interface may be provided to achieve connection with the fan board.

[0041] In this embodiment, the server also includes a fan and a fan board, the fan is installed on the fan board, and the fan board is electrically connected to the connection interface 20 of the server mainboard, thereby improving the convenience of installation and maintenance of the fan on the one hand, and on the other hand, it can be flexibly adjusted according to the actual heat dissipation requirements of the server without adjusting the structure of the server mainboard, thereby improving the reusability of the server mainboard. Specifically, the connection interface 20 of this embodiment includes a power supply interface and a fan board interface, the fan board interface is docked with the fan board, and a docking interface docked with the fan terminal of the fan is set on the fan board, so that the fan terminal interface 21 does not need to be set on the server mainboard. In this way, according to the heat dissipation requirements of the server and the specifications of the fan, the size and shape of the fan board can be flexibly adjusted, and the setting position of the fan can also be adjusted by adjusting the fan board according to the different heat source positions, thereby improving flexibility. At the same time, the maintainability and upgradeability of the fan board make it unnecessary to disassemble and replace the server mainboard even if the heat dissipation requirements change, and only the fan board and the fan need to be adjusted accordingly, thereby improving the adaptability of the server mainboard and extending the service life of the server mainboard.

[0042] Optionally, the fan plate can be arranged adjacent to the first side 11, so as to reduce the space occupied by the fan plate after being connected to the server mainboard. When the space of the server chassis is large, in order to avoid shaking in the server chassis after the fan plate is connected to the server mainboard, the position where the fan plate and the fan plate interface are connected can also be arranged adjacent to the server mainboard, and other positions of the fan plate can be arranged at intervals from the server mainboard to adapt to different server chassis.

[0043] Embodiment 3

[0044] Different from the first embodiment, the position of the onboard data interface 40 and the number of the external card connectors 33 of the present embodiment are different to meet the different connection requirements of the server; and the present embodiment is provided with a cable organizer 50 to further optimize the wiring of the server motherboard. In the first embodiment, the onboard data interface 40 is located between the first side 11 and the second side 12, and there are three external card connectors 33, including one input-output connector and two open computing project card connectors, while in the present embodiment, the onboard data interface 40 is provided on the first side 11, and there are two external card connectors 33, including one input-output connector and one open computing project card connector.

[0045] like Figure 3 , Figure 4As shown, in this embodiment, the connection interface 20 includes a power supply interface and a fan terminal interface 21, and the onboard data interface 40 is located on the first side 11, so as to facilitate the connection between the hard disk and the onboard data interface 40, and facilitate the wiring and layout of the server motherboard. Specifically, the fan terminal interface 21 of this embodiment is located at the edge of the first side 11 and arranged along the extension direction of the first side 11. The onboard data interface 40 is 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, the fan terminal interface 21, and the onboard data interface 40 are all arranged on the first side 11. When the hard disk is set at a position close to the first side 11, this arrangement is conducive to the cable connection between the hard disk backplane and the server motherboard, so that the hard disk interface connected to the backplane can also be located near the first side 11, so as to facilitate the docking with the hard disk, thereby simplifying the wiring of the server motherboard.

[0046] In this embodiment, multiple power supply interfaces and fan terminal interfaces 21 are provided, so as to directly provide power and heat dissipation support for 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, as long as the power and heat dissipation requirements of the server are met. When the server has more flexible heat dissipation requirements, the fan terminal interface 21 can also be set as a fan board interface, and a fan board is separately provided for the server, so that the fan board is directly connected to the fan terminal interface 21, and the fan is directly connected to the fan board, so that when the heat dissipation requirements change, there is no need to frequently disassemble and adjust the server motherboard, thereby improving the reusability of the server motherboard.

[0047] In this embodiment, the connector 30 includes a multi-channel input and output interface 31, a power connector 32 and an external card connector 33. The multi-channel input and output interface 31, the external card connector 33 and the power connector 32 are all located on the second side 12, so as to facilitate the direct connection between the server mainboard and other devices such as external cards and power supplies. Compared with the method of connecting through cables, this method is conducive to shortening the transmission path between the server mainboard and other devices, thereby facilitating the transmission efficiency of the server mainboard. Compared with the multi-channel input and output interface 31, the external card connector 33 is closer to the edge line of the second side 12, and the external card connector 33 of this embodiment is located at the edge of the second side 12, so that the installation and removal of the external card is more convenient, so that the operator does not need to open the cover of the server chassis for maintenance, so as to facilitate the operator to quickly and conveniently replace and upgrade the hardware, while reducing the occupation of the external card in the central area of ​​the board body 10, providing more space for other key components.

[0048] In this embodiment, the plug-in card connector 33 includes an open computing project card connector and an input / output connector, and the open computing project card connector is one, thereby improving the expansion function of the server motherboard. Figure 3 , Figure 4 As shown, the plug-in card connector 33 of this embodiment is arranged in the first section 121, and is arranged in two, one of which is an open computing project card connector, and the other is an input-output connector. The open computing project card connector is used to connect the open computing project card, and the input-output connector is used to connect the management IO card. In this way, an open computing project card and a management IO card can be connected through the plug-in card connector 33, thereby improving the signal transmission efficiency of the open computing project card and the management IO card, and the structure is compact, reducing the space occupied by the server motherboard, and saving the cost of the motherboard. Of course, according to actual needs, both of the two plug-in card connectors 33 can be set as open computing project card connectors, or both of the two plug-in card connectors 33 can be set as input-output connectors.

[0049] It should be noted that the server of this embodiment includes two open computing project cards and two management IO cards. Considering that the space at the edge of the second side 12 of the board body 10 is limited, only two external card connectors 33 are set. In this way, 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 through an external cable; one management IO card is connected to the input and output connector, and the other can be connected to the server motherboard through an external cable, thereby improving the scalability and compatibility of the server motherboard, and improving the signal transmission quality of some open computing project cards and management IO cards, while making full use of the space at the edge of the second side 12 of the board body 10.

[0050] like Figure 3As shown, in this embodiment, the server motherboard also has a cable organizer 50, which is arranged in the middle area of ​​the board body 10, and the cables are inserted into the cable organizer 50, thereby optimizing cable management, reducing the influence of the cables on the heat dissipation of the motherboard, and improving the cleanliness inside the server, which is convenient for maintenance and troubleshooting. Specifically, considering that there is a partial space between the memory of the server motherboard, the cable organizer 50 of this embodiment can be arranged between the memory, so that a part of the cables can be routed from the server motherboard, thereby saving the cable length and saving costs. The length direction of the cable organizer 50 is along the arrangement direction of the first side 11 and the second side 12, and the cable organizer 50 has a bottom plate and two oppositely arranged side plates, wherein the bottom plate is connected to the board body 10, and the two side plates are connected to the bottom plate and are arranged perpendicular to the bottom plate, thereby forming a rectangular cable management space. A plurality of protrusions are provided at one end of the two side panels away from the bottom plate, and the protrusions on the two side panels extend in a direction close to each other to block the cable management space; the protrusions on each side panel are arranged along the length direction of the cable organizer 50, and the protrusions on the two side panels are staggered, so that it is convenient for the cables to enter the cable management space to realize the integrity of the cables, and it is also possible to prevent the cables from easily escaping from the cable management space. In this way, the cables are arranged in the cable management space, which can not only keep the server motherboard and the inside of the server tidy, reduce the impact of the cable clutter on the signal, but also facilitate maintenance personnel to quickly locate and deal with cable-related problems, thereby improving operation and maintenance efficiency and reducing maintenance costs. Of course, the cable organizer 50 can also be set at other free positions on the board body 10 according to actual conditions, and can also be set to other shapes, which can meet the cable management requirements of the server motherboard and do not interfere with other devices on the server motherboard.

[0051] In this embodiment, the server further includes a fan and a hard disk, both of which are externally disposed 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 disk is electrically connected to the onboard data interface 40, thereby improving the heat dissipation performance of the server and the data transmission speed of the hard disk. Specifically, the fan of this embodiment is electrically connected to the fan terminal interface 21, and the fan terminal interface 21 is provided with a plurality of fan terminals along the extension direction of the first side 11, and the fan is also provided near the first side 11, so that the connection between the fan and the fan terminal interface 21 is more convenient and quick, so that the server can conveniently and quickly install a plurality of fans, thereby dissipating heat for the high heat source components inside the server, so as to improve the stability of the server and extend the hardware life. In this embodiment, there are also a plurality of onboard data interfaces 40. Compared with the way in which the hard disk is connected to the server motherboard through a cable, the hard disk is externally disposed on the first side 11, so as to be close to the position of the onboard data interface 40, so that the hard disk can be directly electrically connected to the onboard data interface 40, thereby providing a higher signal transmission quality, which is conducive to improving the performance of the server.

[0052] It should be noted that, the multiple in the above embodiments refers to at least two.
