Description

Technical Field

[0001] The present application relates to the technical field of servers, and in particular to a server. Background Art

[0002] With the continuous development of the AI ​​market, high-performance AI servers are becoming increasingly popular. To ensure heat dissipation performance and a compact server size, servers are typically equipped with multiple PCIe expansion cards, memory cards, CPU (Central Processing Unit) components, and GPU (Graphics Processing Unit) components. Heat dissipation is provided by radiators to prevent overheating.

[0003] However, the height of the server in the above-mentioned related art is relatively high, resulting in the server occupying a relatively large height space in the computer room, thus affecting the layout of the server in the computer room. Summary of the Invention

[0004] The present application provides a server to at least solve the problem in the related art that the server is relatively high, resulting in the server occupying a large height space in the computer room and affecting the layout of the server in the computer room.

[0005] This application provides a server, which includes:

[0006] A chassis having an accommodating cavity therein, and a first window and a second window opposite to each other and communicating with the accommodating cavity along a first direction; the first direction is consistent with an extending direction of the front and rear windows of the chassis;

[0007] a first computing module disposed on a side of the chassis near the first window, wherein a recessed portion is formed on a side of the first computing module facing the top of the chassis along a second direction, wherein the second direction is a height direction of the chassis;

[0008] The second computing module is arranged in the chassis and installed in the recessed portion, and the second computing module is used to assist the first computing module in processing computing tasks.

[0009] Through the present application, since a recess is formed on the side of the first computing module facing the top of the chassis, and the second computing module is installed in the recess of the first computing module, a nested architecture design of the computing module is realized, so that the first computing module and the second computing module are staggered in the second direction, and the space reuse of the first computing module in the height direction of the chassis is realized, rather than the form of staggered arrangement in the second direction in the prior art. In this way, the total height of the combined structure of the first computing module and the second computing module in the second direction is significantly reduced compared with the prior art, making the internal structure of the server more compact, reducing the space occupied by the first computing module and the second computing module in the second direction of the chassis, helping to reduce the height of the chassis, and further reducing the height of the server, for example, reducing the height of the server to 5U. Therefore, the technical problem of the high height of the server in the related art, which causes the server to occupy a large height space in the computer room and affects the layout of the server in the computer room, can be solved, and the technical effect of reducing the height of the server, reducing the space occupied by the server, and facilitating the reasonable layout of the server in the computer room can be achieved.

[0066] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0067] It should be noted that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," and the like, indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely for ease of description and simplification of the present application. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limiting the present application. The terms "mounted," "connected," and "connected" should be interpreted broadly, and may include, for example, fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. The terms "parallel," "perpendicular," and "equal" encompass the described conditions and conditions similar to the described conditions, provided that the range of the similar conditions is within an acceptable range of deviation, as determined by a person of ordinary skill in the art taking into account the measurement in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system). For example, "parallel" includes both absolute parallelism and approximate parallelism, where the acceptable deviation range for approximate parallelism may be, for example, within 5°; "perpendicular" includes both absolute perpendicularity and approximate perpendicularity, where the acceptable deviation range for approximate perpendicularity may also be, for example, within 5°. "Equal" includes both absolute equality and approximate equality, where the acceptable deviation range for approximate equality may be, for example, that the difference between the two is less than or equal to 5% of either. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0068] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0069] As described in the background, servers in related art are relatively tall, which causes them to occupy a significant amount of space in the computer room, impacting their layout. This problem arises because the CPU and GPU components in related art are stacked in the height direction of the chassis. The height of the chassis is affected by the sum of the heights of the CPU and GPU components. The greater the sum of the two heights, the taller the chassis needs to be, resulting in a taller server, which in turn occupies a significant amount of space in the computer room.

[0070] refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4An embodiment of the present application provides a server, which may include a chassis 100, a first computing module 200 and a second computing module 300.

[0071] The chassis 100 may have an accommodating cavity 110 inside, and a first direction (eg Figure 2 The first window 120 and the second window 130 are opposite to and communicate with the accommodating cavity 110 in the X direction. The first direction is consistent with the extending direction of the front and rear windows of the chassis 100.

[0072] It is understood that the interior of the chassis 100 having the accommodating cavity 110, as well as the first window 120 and the second window 130, which are opposite and connected to the accommodating cavity 110 along a first direction, means that the chassis 100 has a front-to-back installation channel. Specifically, this can be achieved using a metal frame with a removable panel. The first window 120 is used to install the computing module, and the second window 130 is used to connect the heat sink and power module, facilitating modular maintenance and airflow circulation. Specifically, the first window 120 is a front window facing the front of the chassis 100, and the second window 130 is a rear window facing the rear of the chassis 100.

[0073] The first computing module 200 is disposed on a side of the chassis 100 close to the first window 120 and along the second direction (eg Figure 2 The first computing module 200 has a concave portion 210 formed on one side of the chassis 100 facing the top, and the second direction is the height direction of the chassis 100. The first computing module 200 can be disposed in the receiving cavity 110 of the chassis 100 through the first window 120.

[0074] It is understood that the first computing module 200 can adopt a stepped layout design to form the lower recess 210. For example, by staggering the components in the first computing module 200 in the second direction to form a stepped structure and simultaneously forming a recess, the height difference is utilized to save vertical space and provide a mounting location for the second computing module 300.

[0075] The second computing module 300 is disposed within the chassis 100 and mounted within the lower recess 210 , thereby achieving a nested design between the second computing module 300 and the first computing module 200 and reusing the space within the accommodating cavity 110 occupied by the first computing module 200 in the height direction. The second computing module 300 is used to assist the first computing module 200 in processing computing tasks. The second computing module 300 can be disposed within the accommodating cavity 110 of the chassis 100 through the first window 120 .

[0076] In a specific implementation, the second computing module 300 can be first installed in the lower recess 210 of the first computing module 200 , and then the combined structure of the first computing module 200 and the second computing module 300 is installed in the accommodating cavity 110 through the first window 120 of the chassis 100 .

[0077] In some embodiments, the second computing module 300 can be directly placed in the concave portion 210 , so that the first computing module 200 can carry and support the second computing module 300 .

[0078] Alternatively, the second computing module 300 and the first computing module 200 can also be assembled in a detachable connection manner, which can improve the connection stability between the first computing module 200 and the second computing module 300, and can prevent the combination of the first computing module 200 and the second computing module 300 from shaking during installation in the accommodating cavity 110, thereby improving the assembly efficiency of the first computing module 200, the second computing module 300 and the chassis 100, or can prevent the second computing module 300 from shaking relative to the first computing module 200 in the chassis 100, thereby improving the structural stability of the server.

[0079] In some embodiments, in the second direction, the second computing module 300 can be completely located in the recess 210 of the first computing module 200. For example, the surface of the second computing module 300 facing the top of the chassis 100 does not protrude from the opening 211 of the recess 210 toward the top of the chassis 100. In this case, the second computing module 300 will not affect the height of the chassis 100.

[0080] Alternatively, in the second direction, the recess 210 can accommodate part of the second computing module 300, and a part of the second computing module 300 is located in the recess 210. In this way, only the part of the structure of the second computing module 300 protruding from the recess 210 will affect the height of the chassis 100, and will also reduce the total height of the second computing module 300 and the second computing module 300 to a certain extent.

[0081] An embodiment of the present application provides a server, which realizes a nested architectural design of the computing modules by forming a recess 210 on one side of the first computing module 200 facing the top of the chassis 100, and installing the second computing module 300 in the recess 210 of the first computing module 200, so that the first computing module 200 and the second computing module 300 are staggered in the second direction, and spatial reuse of the first computing module 200 in the height direction of the chassis 100 is realized, rather than the staggered arrangement in the second direction in the prior art. In this way, the total height of the combined structure of the first computing module 200 and the second computing module 300 in the second direction is significantly reduced compared with the prior art, making the internal structure of the server more compact, reducing the space occupied by the first computing module 200 and the second computing module 300 in the second direction inside the chassis 100, helping to reduce the height of the chassis 100, and further reducing the height of the server, for example, reducing the height of the server to 5U, where U can be inches and 5U can be understood as 5 inches.

[0082] Therefore, the technical problem in the related technology that the server is too high, causing the server to occupy a larger height space in the computer room and affecting the layout of the server in the computer room can be solved, and the technical effect of lowering the server height, reducing the space occupied by the server, and facilitating the reasonable layout of the server in the computer room can be achieved.

[0083] refer to Figure 3 In some embodiments, the first computing module 200 may be a CPU (Central Processing Unit) computing module, and the second computing module 300 may be a GPU (Graphics Processing Unit) computing module.

[0084] In high-performance AI servers, the CPU computing module is responsible for general computing tasks, while the GPU computing module focuses on deep learning and large-scale parallel computing tasks.

[0085] refer to Figure 3 In some embodiments, along the second direction, the lower recess 210 has an opening 211 facing the top of the chassis 100 , and the second computing module 300 does not protrude from the opening 211 of the lower recess 210 .

[0086] The opening 211 may refer to the open area formed in the height direction of the top of the lower recess 210. "Non-protrusion" may mean that the second computing module 300 is completely accommodated in the height direction of the lower recess 210. This can be achieved by controlling the installation height of the second computing module 300 to be flush with or lower than the plane of the opening 211, for example, by using a mounting structure that conforms to the inner wall of the lower recess 210.

[0087] Through the above technical solution, by making the second computing module 300 not protrude from the opening 211 of the lower recess 210, it is possible to avoid the second computing module 300 increasing the space in the height direction of the chassis 100, and thus the height of the chassis 100 can be designed only according to the height of the first computing module 200, thereby reducing the height of the chassis 100 and the height of the server.

[0088] refer to Figure 3 In some embodiments, the server may further include a first handle 160 , which is disposed on an outer side wall of the chassis 100 .

[0089] If the chassis 100 includes a first side wall and a second side wall opposite to each other along the third direction, a plurality of first handles 160 can be respectively provided on the first side wall and the second side wall.

[0090] The first handle 160 provided on the outer sidewall of the chassis 100 provides a convenient grip for the operator. This makes it easier for the operator to carry or move the server. This improves the ease of transport and reduces physical exertion. Furthermore, the design of the first handle 160 makes the server more stable during transport, reducing the risk of damage due to improper handling.

[0091] refer to Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 In some embodiments, the first computing module 200 may include an expansion unit 220 , a first storage unit 230 , and a first computing unit 240 .

[0092] The extension unit 220 can be arranged closer to the bottom of the chassis 100 relative to the top of the chassis 100 , and the extension unit 220 can play a certain supporting role.

[0093] The expansion unit 220 may refer to a component for providing computing expansion capability, for example, a plurality of expansion units along a third direction (eg, Figure 5 The expansion card 221 is arranged in the Y direction (in the middle Y direction), and the third direction is perpendicular to the first direction and the second direction. The expansion unit 220 can provide additional functional support for the server, such as data transmission or signal processing, by increasing the number of interfaces or processing capabilities.

[0094] Along the second direction, the first storage unit 230 is disposed on a side of the expansion unit 220 that faces the top of the chassis 100. The expansion unit 220 can be used to support the first storage unit 230. The first storage unit 230 can be a module for data storage and can be implemented as a structure comprising multiple storage components, such as hard disks or solid-state drives. The first storage unit 230 is arranged vertically above the expansion unit 220, fully utilizing the vertical space and avoiding interference with the expansion unit 220.

[0095] Along the first direction, the first computing unit 240 is disposed on a side of the first storage unit 230 facing the second window 130 , and the second computing module 300 is disposed on a side of the first computing unit 240 facing the top of the chassis 100 .

[0096] The first computing unit 240 may refer to a component that performs core computing tasks, and may be implemented using a motherboard structure equipped with a processor. The processor may be a CPU, and the processor may be thermally managed through a liquid cooling unit.

[0097] Along the second direction, the surface of the first computing unit 240 facing the top of the chassis 100 is lower than the surface of the first storage unit 230 facing the top of the chassis 100, so that the expansion unit 220, the first storage unit 230, and the first computing unit 240 together form a recessed portion 210. The first computing unit 240 is arranged behind the first storage unit 230 along the front-to-back direction, forming a stepped structure, so that the top of the first computing unit 240 is lower than the top of the first storage unit 230, thereby forming a recessed portion 210 together with the expansion unit 220. The first computing unit 240 can be used to support the second computing module 300. The expansion unit 220 and the first storage unit 230 can protect and limit the side of the second computing module 300 facing the first window 120, preventing the second computing module 300 from displacing relative to the first computing module 200 in the second direction, thereby improving the connection stability between the various components inside the chassis 100.

[0098] Through the above technical solution, the structure of the first computing module 200 is further refined. The height difference formed by the layout of the expansion unit 220, the first storage unit 230 and the first computing unit 240 naturally forms the lower concave portion 210 while ensuring that the height of the chassis 100 is relatively low. No additional support structure is required, which simplifies the assembly process and ensures structural strength.

[0099] This layered structure clearly defines the functional divisions within the first computing module 200. The expansion unit 220, first storage unit 230, and first computing unit 240 each perform distinct functions while working in conjunction with each other. The presence of the recessed portion 210 provides installation space for the second computing module 300, further optimizing space utilization and making the internal structure of the chassis 100 more compact. The coordinated operation of these various components enhances overall performance.

[0100] refer to Figure 5 and Figure 7 In some embodiments, the expansion unit 220 may include multiple expansion cards 221 arranged along a third direction, which is perpendicular to the first and second directions. The third direction may be the width of the chassis 100. The width of the chassis 100 is perpendicular to the front-to-back direction and the height of the chassis 100, and the width is perpendicular to the height of the chassis 100. Specifically, the third direction may be defined by a coordinate axis perpendicular to the front-to-back direction and the height of the chassis 100.

[0101] In some embodiments, expansion card 221 provides additional server functionality, such as data transmission or signal processing, by increasing the number of interfaces or processing power. Expansion can be achieved using full-height PCIE (Peripheral Component Interconnect Express) cards, up to 12 of which are arranged across the width of chassis 100 to enhance the server's computing and expansion capabilities.

[0102] The expansion unit 220 has a plurality of expansion cards 221 arranged transversely along the third direction, forming a stable support structure for the first computing unit 240 inside the chassis 100 .

[0103] The first computing module 200 may further include a second storage unit 250 . The second storage unit 250 is disposed below the first storage unit 230 and between two adjacent expansion cards 221 .

[0104] The second storage unit 250 is an additional storage module located below the first storage unit 230. Specifically, it can be implemented using a structure comprising multiple storage components, such as hard disks or solid-state drives. While ensuring the server's scalability, the second storage unit 250 can be further installed between the two expansion cards 221 to increase storage capacity and optimize space utilization.

[0105] The above technical solution provides a second storage unit 250 between expansion cards 221, fully utilizing the space and further increasing storage capacity. This design improves the server's storage capacity without increasing additional space, meeting the increased storage requirements of high-performance servers while maintaining the overall compactness of the structure.

[0106] refer to Figure 5 and Figure 7 In some embodiments, the first computing module 200 may further include a first housing 260 . The first housing 260 has a first cavity therein for accommodating the expansion unit 220 , the first storage unit 230 , the first computing unit 240 , and the second storage unit 250 .

[0107] The first housing 260 can be designed along the outer contours of the expansion unit 220, the first storage unit 230, and the first computing unit 240 to ensure that the concave portion 210 is formed at the corresponding portion of the first computing unit 240. For example, the first housing 260 can be stepped to ensure that the concave portion 210 is formed.

[0108] The first housing 260 may refer to the support structure that encloses the internal components of the first computing module 200. Specifically, it may be implemented as a combination of a metal frame and panels. Its function is to provide physical protection for the internal components and form a modular unit. The modular structure facilitates overall pull-out maintenance. The first cavity refers to the enclosed space formed within the first housing 260. Specifically, it may be implemented by partitioning the area with partitions. It is used to centrally accommodate the expansion unit 220, the first storage unit 230, and the first computing unit 240, reducing the installation complexity caused by the dispersed layout of the components.

[0109] The above technical solution integrates the expansion unit 220, first storage unit 230, first computing unit 240, and second storage unit 250 into a single cavity through the provision of a first housing 260, achieving a modular design. This design facilitates assembly and maintenance, improves production efficiency, and enhances structural stability. The modular design also makes connections between units more reliable, reduces the risk of failures due to external interference, and improves server reliability.

[0110] In addition, the first shell 260 can also support the second computing module 300 to prevent the first computing unit 240 from being damaged due to direct pressure, thereby improving the protection performance of the first computing unit 240 and other components.

[0111] In some embodiments, a second handle 261 may also be provided on the first shell 260. The second handle 261 is provided on the side of the first shell 260 facing the first window to provide a force point, so that the user can use the second handle 261 to drive the first computing module 200 to be inserted into the accommodating cavity 110 of the chassis 100.

[0112] refer to Figure 7 and Figure 9 In some embodiments, the first storage unit 230 may include a second housing 231 , a plurality of first storage members 233 , a first connecting member 234 , and a second connecting member 235 .

[0113] The second housing 231 has a second cavity 232 therein. The second housing 231 is an independent structure for accommodating a plurality of first storage elements 233 and can be made of metal or plastic. A closed or semi-closed second cavity 232 is formed therein to protect the first storage elements 233 from the external environment.

[0114] A plurality of first storage elements 233 are disposed in the second cavity 232. The first storage element 233 may be a hard disk for storage, and the number of the first storage elements 233 may be four.

[0115] The first connecting member 234 is used to detachably connect the second shell 231 to the first shell 260 , and the second connecting member 235 is used to detachably connect the second shell 231 , the first shell 260 and the chassis 100 .
