[0044] This embodiment provides a large multi-graphics card server. Figure 1 and Figure 2 Shown is a schematic diagram of the internal structure of a large multi-graphics card server in one embodiment of the present application. Figure 3 and Figure 4Shown is a top view of the internal structure of a large multi-graphics card server in one embodiment of the present application. Figure 5 Shown is a front view of a large multi-graphics card server in one embodiment of the present application. Figure 6 Shown is a rear view of a large multi-graphics card server in one embodiment of the present application. Figure 7 The figure shows the overall external structure of the chassis assembly structure of a large multi-graphics card server of the present application in one embodiment. Figure 8 The figure shows a top view of the chassis assembly structure of a large multi-graphics card server of the present application in one embodiment. Figure 9 The right side view of the chassis assembly structure of a large multi-graphics card server of the present application in one embodiment is shown. Figures 1 to 9 As shown, the large multi-graphics card server 100 of this embodiment includes: a server box 110, a motherboard unit 120, a first graphics card unit 130, a second graphics card unit 140, a fan unit 150, a PCIE card unit 180, a hard disk unit 160 and a power supply unit 170.
[0045] In this embodiment, the height of the server case 110 is 6.5U, and the server case 110 forms a front half space and a rear half space along the length direction; the first graphics card unit 130 and the second graphics card unit 140 respectively include ten parallel arranged graphics cards, and each of the graphics cards in the first graphics card unit 130 is arranged in the lower area of the front half space of the server case 110, and each of the graphics cards in the second graphics card unit 140 is arranged in the upper area of the rear half space of the server case 110; the motherboard unit 120 is arranged close to the upper cover of the server case 110, that is, it is arranged above the first graphics card unit 130 and the second graphics card unit 140, and the motherboard unit 120 is respectively connected to each graphics card in the first graphics card unit 130 and the second graphics card unit 140, the fan unit 150, the PCIE card unit 180, the hard disk unit 160 and the power supply unit 170.
[0046] In the server structure of this application, a 6.5U high server chassis is designed, and the motherboard is set above the graphics card, which can install up to 20 graphics cards, greatly increasing the number of graphics cards in a single server and improving the performance of a single server, which can meet the high requirements of some fields for graphics card servers.
[0047] The large multi-graphics card server 100 of this embodiment is described in detail below.
[0048] In this embodiment, the server box 110 is a carrier for installing other units. The material of the server box 110 can be 1mm-3mm thick galvanized steel plate. The chassis made of galvanized steel plate has a certain anti-corrosion ability and is cheaper than paint.
[0049] In this embodiment, the height of the server case 110 is 6.5U, the width is 19 inches, and the length can be made into different lengths according to the length of the graphics card, suitable for 19-inch standard rack installation. The height of the server case 110 is approximately 6.5U, which means that the height of the case is 6.5 units (U). In computer hardware, U is a unit used to measure the size of a server cabinet, and 1U is equal to 1.75 inches (approximately 4.445 centimeters). Therefore, the height of 6.5U can be calculated as: 6.5×1.75=11.375 inches; or converted to centimeters: 11.375×2.54=28.8925 centimeters; therefore, the height of a 6.5U case is approximately 28.89 centimeters. This embodiment increases the height of the existing server case 110 to accommodate a larger number of graphics cards.
[0050] Specifically, in this embodiment, the server box 110 forms a front half space and a rear half space along the length direction; wherein the front half space and the rear half space are the front space and the rear space of the server box 110, and the front half space and the rear half space can be closed spaces or non-closed spaces, and this embodiment does not make clear restrictions on this.
[0051] In this embodiment, the motherboard unit 120 is positioned significantly differently from existing motherboards. It is located close to the top cover of the server chassis 110, above the first graphics card unit 130 and the second graphics card unit 140. This facilitates connection to more graphics cards. The motherboard unit 120 has multiple high-speed signal interfaces for connecting to the PCIE interfaces of graphics cards. The number of high-speed signal interfaces on the motherboard unit 120 matches the total number of graphics cards, PCIE cards, and hard drives.
[0052] In this embodiment, if Figure 1 and Figure 2 As shown, the first graphics card unit 130 and the second graphics card unit 140 each include ten graphics cards arranged in parallel. That is, the server in this embodiment includes 20 dual-slot graphics cards. The graphics cards need to be passively cooled and do not have their own fans. This can minimize the distance between the graphics cards and eliminate the need to reserve air intake space between the graphics cards.
[0053] In this embodiment, the graphics cards in the first graphics card unit 130 are arranged in the lower area of the front half of the space of the server case 110, and the graphics cards in the second graphics card unit 140 are arranged in the upper area of the back half of the space of the server case 110; the graphics cards in the front half of the space of the server case 110 and the graphics cards in the back half of the space of the server case 110 are staggered up and down, which can prevent the hot air from the graphics cards in the front half of the space from flowing directly to the graphics cards in the back half of the space, which is beneficial to the heat dissipation of the graphics cards in the back half of the space.
[0054] In one possible implementation, the graphics card is dual-slot thick, meaning it occupies two PCIe slots on the motherboard unit 120. The graphics card's slot thickness directly impacts its installation position and space within the server chassis 110. Compared to single-slot or triple-slot graphics cards, dual-slot graphics cards offer a design balance, meeting medium-performance requirements for heat dissipation and circuit design without excessively occupying the limited space within the chassis.
[0055] In a possible embodiment, each of the graphics cards is connected to the motherboard unit 120 via a PCIE extension cable. In a possible embodiment, the height difference between each of the graphics cards in the first graphics card unit 130 and each of the graphics cards in the second graphics card unit 140 is 2U.
[0056] Specifically, in one possible embodiment, the first graphics card unit 130 includes 10 of the aforementioned graphics cards; and the second graphics card unit 140 includes 10 of the aforementioned graphics cards. That is, in this embodiment, the number of graphics cards is a maximum of 20 dual-slot graphics cards, which are connected to the motherboard unit 120 via PCIE extension cables. Compared to existing graphics card servers on the market, more graphics cards can be installed, thereby improving the performance of a single server. Therefore, in this embodiment, an example of a distribution method for the graphics cards is as follows: 10 graphics cards are installed at the front and back of the chassis, with the 10 graphics cards at the front of the chassis placed near the lower half of the chassis, and the 10 graphics cards at the back of the chassis placed near the upper half of the chassis. This way, the front and back graphics cards are offset by approximately 2U in height, preventing hot air from the front graphics cards from flowing directly to the 10 graphics cards at the back, which is beneficial for heat dissipation of the 20 graphics cards at the back.
[0057] In one possible implementation, Figure 1 and Figure 3As shown, the fan unit 150 includes a first fan unit 151, a second fan unit 152 and a third fan unit 153; the first fan unit 151 and the second fan unit 152 are respectively arranged in the front area of the front half space and the front area of the back half space, and correspond to the first graphics card unit 130 and the second graphics card unit 140 respectively; the third fan unit 153 is arranged between the first graphics card unit 130 and the second graphics card unit 140, and the third fan unit 153 includes two layers of fans stacked up and down.
[0058] In this embodiment, the chassis air duct is set to be front-to-back, and three rows of cooling fans are set in the chassis, namely front, middle and rear, which can provide a good heat dissipation environment for the graphics card.
[0059] In this embodiment, the fan speed can be adjusted according to the temperature of the mainboard unit 120 or the CPU.
[0060] In this embodiment, the first fan unit 151 and the second fan unit 152 each include a fan assembly, each of which includes a fan bracket and four fans. The third fan unit 153 includes two fan assemblies stacked one above the other, each of which includes a fan bracket and four fans. Therefore, the third fan unit 153 includes eight fans stacked one above the other. The fan unit 150 of this embodiment has four fans installed behind each of the first graphics card unit 130 and the second graphics card unit 140, and eight fans stacked one above the other in the middle to dissipate heat from the first graphics card unit 130 and the second graphics card unit 140.
[0061] In this embodiment, if Figure 5 As shown, the PCIE card unit 180 includes multiple PCIE (Peripheral Component Interconnect Express, a high-speed serial computer expansion bus standard) cards, such as high-speed network cards, for data transmission. In one possible embodiment, the PCIE card unit 180 is disposed in the upper area of the front half of the space and is located in the front area of the server housing 110. Each PCIE card in the PCIE card unit 180 is connected to the motherboard unit 120 via a PCIE extension cable.
[0062] Specifically, since the graphics card is installed in the lower area of the front half of the space, and the PCIE card is installed in the upper area of the front half of the space, the PCIE card is a standard half-height PCIE card. In one possible embodiment, the PCIE card unit 180 includes four half-height PCIE cards. That is, in this embodiment, the maximum number of half-height PCIE cards is four.
[0063] In one possible implementation, Figure 6 As shown, the hard disk unit 160 is arranged in the upper area of the rear half of the space of the server box 110. The server box 110 is provided with a hard disk backplane 161, and the hard disk backplane 161 is connected to the motherboard unit 120 through a high-speed line. Figure 4 As shown, the hard disk unit 160 is connected to the hard disk backplane 161 in a hot-swappable manner. Therefore, the hard disk unit 160 in this embodiment can be installed in a hot-swappable manner, which is convenient for replacement and maintenance.
[0064] Among them, the hard disk unit 160 includes a hard disk and a hard disk tray for installing the hard disk. The hard disk unit 160 can be hot-swapped installed in the following way: first install the hard disk on the hard disk tray, then insert it into the chassis and connect it to the hard disk backplane 161, and the hard disk backplane 161 is connected to the mainboard unit 120 through a high-speed line.
[0065] In this embodiment, the hard disk can be a 3.5-inch hard disk or a 2.5-inch hard disk, and the number of hard disks is 4, so this embodiment can install 4 half-height PCIE cards and 4 hard disks, which effectively compensates for the shortcomings of the existing graphics card server, such as slow data transmission and small storage capacity.
[0066] The power supply unit 170 is used to supply power to the large multi-graphics card server 100 and is responsible for converting 220V AC power into the low-voltage DC power required by each unit. In this embodiment, the power supply unit 170 uses a hot-swappable power supply unit 170 commonly used on servers, which facilitates replacement and maintenance of the power supply unit 170.
[0067] In one possible implementation, Figure 6 As shown, the power supply unit 170 is disposed in the upper area of the rear half of the space of the server housing 110, adjacent to the hard disk unit 160, and located above the hard disk unit 160, as shown in FIG. Figure 4 As shown, a power backplane 171 is provided on the server box 110 , and the power supply unit 170 is connected to the power backplane 171 in a hot-swappable manner.
[0068] In one embodiment, the number of power supply units 170 is five. Each power supply unit 170 is hot-swappable and provides low-voltage DC power to the entire computer. The power supply units 170 are connected to a power backplane 171 installed inside the chassis. The power backplane 171 then distributes the current to the components requiring power via cables.
[0069] To sum up, in the server structure of this application, a 6.5U high server chassis is designed, and the motherboard is set above the graphics card, which can install up to 20 graphics cards, greatly increasing the number of graphics cards in a single server and improving the performance of a single server, which can meet the high requirements of graphics card servers in some fields; and this application can install multiple half-height PCIE cards and multiple hard drives, which makes up for the shortcomings of existing graphics card servers with slow data transmission and small storage capacity.
[0070] The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical concepts disclosed in this application shall be covered by the claims of this application.
