[0023] The server cabinet can be an AI (Artificial Intelligence) integrated cabinet server. The AI integrated cabinet server is a high-performance computing infrastructure designed specifically for artificial intelligence (AI) applications. It integrates computing nodes and switching nodes, and through in-depth optimization of hardware, software, and architecture, it meets the high computing power requirements for AI training, inference, and large-scale data processing.

[0024] Figure 1 The following is a schematic structural diagram of a server cabinet provided by an embodiment of this application. Please refer to Figure 1 , the server cabinet can include multiple computing nodes, multiple switching nodes, a Power Distribution Unit (PDU), and a cooling unit. The height of the server cabinet can be between 42U and 47U. 1U can represent a rack unit, and the height of a rack unit can be 1.75 inches (about 4.45 cm), and it can also be adjusted according to the actual situation without specific limitations.

[0025] The total height of this server cabinet is 44U. In the example of this application, there are 16 computing nodes and 12 switching nodes in total. Please refer to Figure 1 for the front structure. The 16 computing nodes can be deployed on the upper and lower sides of the 12 switching nodes respectively. Each computing node and each switching node can occupy a height of 1U. The 12 switching nodes occupy a height of 12U. The 8 computing nodes on the upper side of the switching nodes occupy a height of 8U, and the 8 computing nodes on the lower side of the switching nodes occupy a height of 8U. It should be noted that the number of computing nodes and the number of switching nodes are only examples and can be adjusted according to the actual situation.

[0026] Please refer to Figure 1 for the front structure. In the server cabinet, the structural strength and stability of the server rack can be increased through rack reinforcement members. The rack reinforcement members are deployed on both sides of multiple computing nodes and multiple switching nodes, and one rack reinforcement member occupies a height of 1U. The cooling unit can be deployed at the bottom of the server cabinet. The cooling unit can cool the server cabinet, and the cooling unit occupies a height of 4U of the server cabinet. Two PDUs can also be deployed in the server cabinet. The PDUs can provide power for the server cabinet, and one PDU occupies a height of 2U. The remaining 6U height of the server cabinet can be used to deploy other components suitable for the server cabinet, which can be marked as the NA (Not Applicable) layer.

[0027] Please refer to Figure 1The back structure may include a bus duct, a manifold, and a Cable Tray on the back of the server cabinet. The power distribution unit is connected to the bus duct to supply power to the server cabinet. The cooling unit controls the inlet and outlet of the manifold to form a liquid path for liquid cooling of the server cabinet. The Cable Tray is used to connect the high-speed signals of the computing nodes and the switching nodes according to the designed topological interconnection relationship. It should be noted that Figure 1 The shown positions and structures of the bus duct, the manifold, and the Cable Tray are only examples, and the positions and quantities can be adjusted according to actual situations.

[0028] The topological interconnection relationship between multiple computing nodes and multiple switching nodes can be a Clos architecture. The Clos architecture is a multi-level network topology structure that can include an access layer and an intermediate layer. In the access layer, each computing node can be connected to the corresponding switching node. In the intermediate layer, multiple switching nodes can be designed for full interconnection to form a network topology. Then, through the network topology corresponding to the switching nodes, it can be ensured that each computing node can be interconnected with any other computing node in the cabinet, realizing full interconnection of the computing nodes.

[0029] A plurality of first connectors can be provided at the back end of the computing node, and a plurality of second connectors can be provided at the back end of the switching node. The first connector of the computing node can be connected to the second connector of the switching node through a high-speed cable. The connector can be a high-speed connector. The high-speed connector is a connector for high data rate transmission and can be used to support the rapid transmission of a large amount of data between the switching node and the computing node.

[0030] In the related art, multiple computing nodes are arranged longitudinally, and each computing node can include a plurality of first connectors arranged horizontally. Multiple switching nodes are arranged longitudinally, and each switching node includes a plurality of second connectors arranged horizontally. For any one computing node, the multiple connectors of the computing node are respectively connected to the first column of connectors in the multiple switching nodes. When the distance between the computing node and the switching node is relatively far, the cable length between the first connector of the computing node and the second connector of the switching node is relatively long, resulting in low communication quality.

[0031] In the embodiments of the present application, the positions of the second connectors in the switching node can be adjusted. There is at least one set of switching node sets whose arrangement positions in multiple sets of switching node sets are inconsistent with the arrangement positions of the corresponding first connector groups in multiple first connector groups, and / or there is at least one second connector whose arrangement position is inconsistent with the arrangement position of the corresponding computing node set, which can shorten the distance between the first connector and the second connector with the longest cable length, make the lengths of the multiple cables between each first connector and each second connector balanced, and improve communication quality.

[0032] To enable those skilled in the art of the present technology to better understand the solution of this application, the following provides a further detailed description of this application in conjunction with the accompanying drawings and specific embodiments.

[0033] In conjunction with the specific application environment architecture or specific hardware architecture relied on by the server cabinet provided in this application, the specific application environment architecture or specific hardware architecture is described herein.

[0034] Figure 2A It is a schematic structural diagram of a server cabinet provided by an embodiment of this application. Please refer to Figure 2A , this server cabinet includes 16 computing nodes and 12 switching nodes. The computing nodes are respectively computing node 1 - 16, and the switching nodes are respectively switching node 1 - 12. Each computing node is provided with 6 first connectors, with a total of 16 * 6 first connectors. Each switching node is provided with 8 second connectors, with a total of 12 * 8 second connectors. Each second connector can be provided with two second connector interfaces. Among them, the 1st to 16th computing nodes are indicated by letters A - H, J - N, P - R, and the 1st to 6th first connectors are indicated by Arabic numerals 1 - 6. Then, A1 can indicate the 1st first connector of the 1st computing node, A2 indicates the 2nd first connector of the 1st computing node,..., R6 indicates the 6th first connector of the 16th computing node. Please refer to Table 1 shown below. Among them, the 1st computing node to the 16th computing node are indicated by computing node 1 - 16, and the 1st first connector to the 6th first connector are indicated by first connector 1 - 6.

[0035] Table 1

[0036]

[0037] Please refer to Figure 2A , in this server cabinet, the first computing node group includes the 1st to 8th computing nodes, and the second computing node group includes the 9th to 16th computing nodes. The 1st to 8th computing nodes are on the upper side of the 12 switching nodes, and the 9th to 16th computing nodes are on the lower side of the 12 switching nodes to place the 12 switching nodes in the middle.

[0038] The arrangement direction of multiple computing nodes and multiple switching nodes is the first direction, and the second direction is perpendicular to the first direction. Please refer to Figure 2A , multiple computing nodes and multiple switching nodes are arranged longitudinally, that is, the longitudinal arrangement direction is the first direction. The second direction is perpendicular to the first direction. In the second direction, multiple first connectors can be respectively set in each computing node, and multiple second connectors can be respectively set in each switching node.

[0039] Please refer to Figure 2A, each first connector of each computing node is provided with 2 first connector interfaces, and the 2 first connector interfaces can be respectively connected to the second connectors of two switching nodes; at the same time, 2 connector interfaces are provided in each second connector, and through the 2 connector interfaces, the second connector can also be respectively connected to the first connectors of two computing nodes. The matching relationship between the first connector and the second connector can be called a 2:2 matching relationship.

[0040] Taking the first computing node as an example, the first connector A1 is respectively connected to the first connector interface of the first second connector of the first switching node and the first connector interface of the first second connector of the second switching node through cables; taking the second computing node as an example, the first connector B1 is respectively connected to the second connector interface of the first second connector of the first switching node and the second connector interface of the first second connector of the second switching node through cables; and so on for other connections. Figure 1 Other cable connections are omitted in , and only a group of cables connected by the first connector A1 is shown. The identifier of the connected first connector is marked on the second connector of each switching node, and the first connector is connected to the second connector marked with its identifier. For example, the identifier A1 of the first first connector of the first computing node is marked at the position of the first connector interface of the first second connector of the first switching node, and the identifier B1 of the first first connector of the second computing node is marked at the position of the second connector interface of the first second connector of the first switching node.

[0041] In some possible embodiments, the matching relationship between the first connector and the second connector can also be in the form of 3:3 matching, 4:4 matching, or other matching relationships. In this application, the 2:2 matching relationship is taken as an example for description.

[0042] Please refer to Figure 2A , in the case of multiple switching nodes, the computing nodes in the upper half and the computing nodes in the lower half are in a centrosymmetric relationship, as shown by the dashed line in Figure 2A . The topologies and lengths of the cables connecting the symmetric computing nodes and switching nodes are also the same. Next, please refer to Figure 2B , taking the computing nodes in the upper half as an example, the distance between any first connector and the corresponding second connector is described, so that those skilled in the art of this technology can better understand the solution of this application.

[0043] Figure 2B This is a schematic diagram of the distance between connectors provided by an embodiment of this application. Please refer to Figure 2B, the direction from the 1st to the 6th first connectors is the second direction, and the direction from the 1st to the 16th computing nodes is the first direction.

[0044] Please refer to Figure 2B , in the first direction, the distance between every two computing nodes is 1 unit length (1Y, where Y indicates the unit length in the first direction), so the distance from the 1st computing node to the 8th computing node is 7Y; the distance from the 8th computing node to the 1st switching node is 1Y; the distance between every two switching nodes is 1Y, so the distance from the 8th computing node to the 12th switching node is 12Y. Then, the coordinates of computing nodes 1 - 8 in the first direction are 1Y - 7Y respectively, the coordinates of switching nodes 1 - 12 in the first direction are 8Y - 19Y respectively, and the coordinates of computing nodes 9 - 16 in the first direction are 20Y - 27Y respectively.

[0045] Please refer to Figure 2B , in the second direction, the distance between every two first connectors is 1 unit length (1X, where X indicates the unit length in the second direction), so the distance from the 1st first connector to the 6th first connector is 5X.

[0046] Please refer to Figure 2B , when the first connectors of the 1st computing node and the 2nd computing node are connected to the second connectors of multiple switching nodes, in the second direction, the cable can be connected to the left of the 1st first connector, and then in the first direction, connected to the second connector of the corresponding switching node; when the first connectors of the 2nd computing node and the 4th computing node are connected to the second connectors of multiple switching nodes, in the second direction, the cable can be connected to the middle between the 1st first connector and the 2nd first connector, and then in the first direction, connected to the second connector of the corresponding switching node; when the first connectors of the 5th computing node and the 6th computing node are connected to the second connectors of multiple switching nodes, in the second direction, the cable can be connected to the middle between the 2nd first connector and the 3rd first connector, and then in the first direction, connected to the second connector of the corresponding switching node; when the first connectors of the 7th computing node and the 8th computing node are connected to the second connectors of multiple switching nodes, in the second direction, the cable can be connected to the right of the 3rd first connector, and then in the first direction, connected to the second connector of the corresponding switching node. In this way, the distance between each first connector and each second connector can be determined. As shown in Table 2, the cable distances between each computing node and each switching node are listed. For example, taking the 1st computing node and the 12th switching node as an example, the distance between the 6th first connector A6 of the 1st computing node and the 1st second connector of the 12th switching node is 5X + 19Y.

[0047] The connection between the first connector and the second connector described above, as well as the method for determining the distance, is only an example provided in this application for the purpose of understanding this application. Other methods for determining the connection and distance will not affect the embodiments of this application and are also within the scope of protection of this application.

[0048] Table 2

[0049]

[0050] It should be noted that the total cable length of all cables in the first direction is fixed. After adjusting the positions of the multiple second connectors of the switching node, the total cable length in the first direction will not change.

[0051] For example, in the first direction, the distances between the first second connector of the 1st - 12th switching nodes and the first first connector of the 8th computing node are 0, 1Y, 2Y, 3Y, 4Y, 5Y, 6Y, 7Y, 8Y, 9Y, 10Y, 11Y respectively, and the distances between the first first connector of the 8th computing node and the first first connectors of the 1st - 7th computing nodes are Y, 2Y, 3Y, 4Y, 5Y, 6Y, 7Y, 8Y respectively. When the arrangement positions of the 1st switching node and the 2nd switching node are interchanged, the distances corresponding to the first connectors in the first direction are also interchanged, and the total cable length in the first direction remains unchanged.

[0052] Similarly, the total cable length of all cables in the second direction is fixed. After adjusting the positions of the multiple second connectors of the switching node, the total cable length in the second direction will not change.

[0053] Based on the above analysis, in the server cabinet provided in the embodiments of the present application, a plurality of first connectors are respectively arranged in the second direction in each computing node, and the plurality of first connectors of each computing node form a plurality of first connector groups in the first direction; a plurality of second connectors are respectively arranged in the second direction in each switching node, and the plurality of second connectors of each switching node form a plurality of second connector groups in the first direction; the plurality of switching nodes include multiple sets of switching node sets, and there is a one-to-one correspondence between each first connector group and each set of switching node sets, the plurality of computing nodes include multiple computing node sets, and there is a one-to-one correspondence between the plurality of second connector groups and the multiple computing node sets. There is at least one set of switching node sets whose arrangement position in the multiple sets of switching node sets is inconsistent with the arrangement position of its corresponding first connector group in the multiple first connector groups, and / or there is at least one second connector group whose arrangement position is inconsistent with the arrangement position of its corresponding computing node set, so that the physical connection distance between any first connector and the second connector is less than the maximum connection distance between the first connector and the second connector.

[0054] In some possible embodiments, the number of the plurality of first connector groups is M, the plurality of switching nodes include M sets of switching node sets, and there is a one-to-one correspondence between the M first connector groups and the M sets of switching node sets, where M is an integer greater than 1.

[0055] Please refer to Figure 2A, in this server cabinet, N is 16 and M is 6. There are 16 computing nodes in this server cabinet. Each computing node corresponds to 6 first connectors, and there are 6 first connector groups in total. The 1st first connector group includes the 1st first connectors of 16 computing nodes, namely the 1st first connector corresponding to the 1st computing node, the 1st first connector corresponding to the 2nd computing node, ……, the 1st first connector corresponding to the 16th computing node (i.e., A1-H1, J1-N1, P1-R1); the 2nd first connector group includes the 2nd first connectors of 16 computing nodes, namely the 2nd first connector corresponding to the 1st computing node, the 2nd first connector corresponding to the 2nd computing node, ……, the 12th first connector corresponding to the 16th computing node (i.e., A2-H2, J2-N2, P2-R2); the 3rd first connector group includes the 3rd first connectors of 16 computing nodes, namely the 3rd first connector corresponding to the 1st computing node, the 3rd first connector corresponding to the 2nd computing node, ……, the 3rd first connector corresponding to the 16th computing node (i.e., A3-H3, J3-N3, P3-R3); the 4th first connector group includes the 4th first connectors of 16 computing nodes, namely the 4th first connector corresponding to the 1st computing node, the 4th first connector corresponding to the 2nd computing node, ……, the 4th first connector corresponding to the 16th computing node (i.e., A4-H4, J4-N4, P4-R4); the 5th first connector group includes the 5th first connectors of 16 computing nodes, namely the 5th first connector corresponding to the 1st computing node, the 5th first connector corresponding to the 2nd computing node, ……, the 5th first connector corresponding to the 16th computing node (i.e., A3-H3, J3-N3, P3-R3); the 6th first connector group includes the 3rd first connectors of 16 computing nodes, namely the 6th first connector corresponding to the 1st computing node, the 6th first connector corresponding to the 2nd computing node, ……, the 6th first connector corresponding to the 16th computing node (i.e., A6-H6, J6-N6, P6-R6).

[0056] Please refer to Figure 2A , there are 6 sets of switching node sets in this server cabinet. Among them, the 1st set of switching node sets includes the 1st switching node and the 2nd switching node; the 2nd set of switching node sets includes the 3rd switching node and the 4th switching node; the 3rd set of switching node sets includes the 5th switching node and the 6th switching node; the 4th set of switching node sets includes the 7th switching node and the 8th switching node; the 5th set of switching node sets includes the 9th switching node and the 10th switching node; the 6th set of switching node sets includes the 11th switching node and the 12th switching node.

[0057] Taking the correspondence between the first first connector group and the first set of switching node sets as an example, please refer to Figure 2A , the 16th first connector (A1) of the first first connector group corresponds to the first set of switching node sets (the second connectors of the first switching node and the second connectors of the second switching node). For the others, there is a one-to-one correspondence between the first connectors and the corresponding switching node groups, which can be referred to in Figure 2A . The description will not be repeated here.

[0058] In some possible embodiments, the number of multiple computing nodes is N, the number of multiple second connector groups is N, and there is a one-to-one correspondence between the N computing nodes and the N second connector groups, where N is an integer greater than 1.

[0059] Please refer to Figure 2A , where N is 16 and M is 6 in this server cabinet. There are 16 computing nodes and 8 second connector groups in total, and each second connector group has 12 second connectors. Taking the first second connector group as an example, the first second connector group has 12 second connectors in total, which are the first second connectors of 12 switching nodes. Among them, each second connector can connect two first connectors. Taking the first second connector of the first switching node as an example, the first second connector of the first switching node is connected to the first first connector A1 and the first first connector B1 of the first computing node. In Figure 2A , the first second connector of the first switching node marks the identification A1 of the first first connector of the first computing node and the identification B1 of the first first connector of the first computing node. Among them, the one-to-one correspondence between the 8 computing node sets and the 8 second connector groups can be referred to in Figure 2A . The description will not be repeated here.

[0060] Furthermore, the server cabinet may include multiple computing nodes and multiple switching nodes. The multiple computing nodes include a first computing node group and a second computing node group. The first computing node group is arranged on one side of the multiple switching nodes, and the second computing node group is arranged on the other side of the multiple switching nodes.

[0061] In some possible embodiments, one side of the multiple switching nodes can be used to indicate the left side of the multiple switching nodes, and the other side of the multiple switching nodes is used to indicate the right side of the multiple switching nodes. Or, one side of the multiple switching nodes can be used to indicate the upper side of the multiple switching nodes, and the other side of the multiple switching nodes is used to indicate the lower side of the multiple switching nodes.

[0062] For example, please refer to Figure 2A, the first computing node group can be computing nodes 1 - 8, the second computing node group can be computing nodes 9 - 16. One side of the multiple switching nodes is the upper side of the multiple switching nodes, and the other side of the multiple switching nodes is the lower side of the multiple switching nodes.

[0063] In this application, by dividing the multiple computing nodes into the first computing node group and the second computing node group and arranging them on both sides of the multiple switching nodes, the distance between the first connector and the second connector in the first direction can be shortened, thereby reducing the communication distance and improving the communication quality of the server cabinet.

[0064] In the following, an embodiment in which one side of the multiple switching nodes is the upper side of the multiple switching nodes and the other side of the multiple switching nodes is the lower side of the switching nodes will be used to illustrate the service machine cabinet improved in this application.

[0065] In the first embodiment provided by this application, with the layout of the multiple switching nodes in the first direction unchanged, the positions of the second connectors in the second direction are adjusted, and at least one second connector group is arranged differently from its corresponding computing node set.

[0066] In some possible embodiments, for the computing node with the longest cable in the first direction, the cable length in the second direction can be the shortest, which can reduce the maximum connection distance between the first connector and the second connector.

[0067] By adjusting the positions of the second connectors in the switching nodes, at least one second connector group is arranged differently from its corresponding computing node set, so that the distance between any one first connector and the corresponding second connector after adjustment is less than the maximum connection distance, reducing the extreme signal transmission distance and improving the communication quality of the server cabinet.

[0068] Specifically, the number of multiple computing nodes is N, each switching node includes N second connector interfaces, and each second connector includes K second connector interfaces. N is an integer greater than 1, and K is an integer greater than 1. Among them, each switching node includes second connectors, and the multiple computing nodes include computing node sets; the existence of at least one second connector group arranged differently from its corresponding computing node set is used to indicate: the sorting queue of the second connector groups is inconsistent with the sorting queue of the corresponding computing node sets. Next, in combination with Figure 3 , the server cabinet provided in the first embodiment of this application will be specifically described.

[0069] Figure 3 It is a schematic structural diagram of a server cabinet provided in the first embodiment of this application. Please refer toFigure 3 The server cabinet includes 16 computing nodes (i.e., N is 16) and 12 switching nodes. The computing nodes are respectively computing nodes 1-16, and the switching nodes are respectively switching nodes 1-12. Each computing node includes 6 first connectors, each switching node includes 8 second connectors, and K is 2.

[0070] Among the 16 computing nodes, there are a total of 8 computing node sets.

Please refer to Figure 5 , this server cabinet includes 16 computing nodes (that is, N is 16), and the computing nodes are respectively computing nodes 1-16.

Without changing the total distance between each first connector and each second connector, shortening the maximum distance between the first connector and the second connector can improve the communication quality.

[0098] In the above-mentioned First Embodiment and Second Embodiment, when the sorting queues of multiple switching nodes are fixed (i.e., the first direction is fixed), the sorting queues of the respective second connectors of each switching node are adjusted to reduce the maximum distance between the first connector and the second connector; in the Third Embodiment, when the positions of multiple second connectors in the switching node are fixed, the sorting queues of multiple switching nodes are adjusted to reduce the maximum distance between the first connector and the second connector.

[0099] The present application further provides a Fourth Embodiment. In the server cabinet provided by the Fourth Embodiment, the sorting queues of multiple switching nodes and the positions of multiple second connectors in the switching nodes are simultaneously adjusted, so that the sorting queues of multiple switching nodes are inconsistent with the sorting queues of the first connectors in the first connector group, and the sorting queues of multiple second connector groups are inconsistent with the sorting queues of multiple computing nodes, which can further shorten the maximum connection distance between the first connector and the second connector.

[0100] Figure 6 FIG. is a schematic structural diagram of a server cabinet provided by the Fourth Embodiment of the present application. Please refer to Figure 6 , the server cabinet includes 16 computing nodes (i.e., N is 16) and 12 switching nodes.

Each computing node includes 6 first connectors, each switching node includes 8 second connectors, and each second connector includes 2 connector interfaces, that is, K is 2.

[0101] The corresponding relationship between each computing node set and each second connector group, as well as the arrangement order of each second connector group in multiple second connector groups, can be referred to Figure 3 the structural embodiment provided. Details are not described herein again. On this basis, the sorting order of multiple switching nodes is further adjusted.

[0104] The order of the 1st set of switching nodes corresponding to the 1st first connector group among the 6 sets of switching nodes is 3; the order of the 2nd set of switching nodes corresponding to the 2nd first connector group among the 6 sets of switching nodes is 2; the order of the 3rd set of switching nodes corresponding to the 3rd first connector group among the 6 sets of switching nodes is 1; the order of the 4th set of switching nodes corresponding to the 4th first connector group among the 6 sets of switching nodes is 6; the order of the 5th set of switching nodes corresponding to the 5th first connector group among the 6 sets of switching nodes is 5; the order of the set of switching nodes corresponding to the 6th first connector group among the 6 sets of switching nodes is 4.

[0105] The server cabinet of Embodiment 4 provided in this application adjusts the sorting queues of multiple switching nodes and the positions of multiple second connectors in the switching nodes at the same time, so that the sorting queues of multiple switching nodes are inconsistent with the sorting queues of multiple first connector groups, and the sorting queues of multiple second connector groups are inconsistent with the sorting queues of multiple computing nodes, which can further shorten the maximum distance between the first connector and the second connector and improve the communication quality of the server cabinet.

[0106] It should be noted that the maximum connection distance provided in the embodiments of this application can be set according to the actual situation of the layout of the server cabinet.

[0107] If the distance between any one of the first connectors and the corresponding second connector in the server cabinet provided in the first embodiment is less than the maximum connection distance, the server cabinet can be laid out according to the structure provided in the first embodiment; if the server cabinet is laid out according to the structure provided in the first embodiment and there is a distance greater than the maximum connection distance between any one of the first connectors and the corresponding second connector, the server cabinet can be laid out according to the structure provided in the second embodiment; if the server cabinet is laid out according to the structure provided in the second embodiment and there is still a distance greater than the maximum connection distance between any one of the first connectors and the corresponding second connector, the server cabinet is laid out according to the structure provided in the third embodiment; if the server cabinet is laid out according to the structure provided in the third embodiment and there is still a distance greater than the maximum connection distance between any one of the first connectors and the corresponding second connector, the server cabinet is laid out according to the structure provided in the fourth embodiment.

[0108] In the first to fourth embodiments provided above, a cable tray is included in the server cabinet. By using the cable tray, multiple cables between any one of the first connectors and the second connector can be routed orderly between the first connector and the second connector.

[0109] Further, another way to effectively reduce the total cable length and the extreme cable length is to divide a cable tray into multiple independent cable trays, so that each independent cable tray has an independent topological connection. There is no connection relationship between the cable trays.

[0110] In the second direction, multiple first connectors can be divided into multiple cable tray groups, and each cable tray group includes at least one first connector group and a set of switching nodes corresponding to each first connector group.

[0111] For any one of the cable tray groups, at least one cable can be led out from at least one first connector of each computing node in the cable tray group to the middle position in the cable tray group and then connected to the corresponding second connector to form a cable tray corresponding to the cable tray group. The cable tray includes multiple cables, and the cables are used to connect the first connector and the second connector. In the second direction, the distance between any one of the first connectors and the corresponding second connector in the cable tray group can be made less than the maximum connection distance.

[0112] Isolation baffles can be included between each of the multiple cable trays, and the isolation baffles can isolate the multiple cables.

Each computing node is provided with M first connectors, and each switching node is provided with N second connectors. Each cable tray group includes first connector groups and switching node sets. Among them, for any cable tray group, the sorting queues of the first connector groups are inconsistent with the sorting queues of the switching node sets.

[0114] In some possible embodiments, each cable tray group includes a first connector of multiple computing nodes and a second connector corresponding to each first connector. Then, in the second direction, the distance between the first connector and the second connector is 0.

This server cabinet includes 16 computing nodes and 12 switching nodes. The computing nodes are respectively computing nodes 1-16, and the switching nodes are respectively switching nodes 1-12 (that is, N is 12). Each computing node includes 6 first connectors (that is, M is 6). The server cabinet includes two cable bridge groups (that is, Q is 2). The left side is the 1st cable bridge group, and the right side is the 2nd cable bridge group. The 1st cable bridge group and the 2nd cable bridge group can be physically separated by an isolation baffle. Since the structures of the 1st cable bridge group and the 2nd cable bridge group are the same, only the 1st bridge group is described here, and the structure of the 2nd cable bridge group can be referred to that of the 1st cable bridge group.

[0116] The 1st cable bridge group includes the 1st first connector group, the 2nd first connector group, the 2nd first connector group, and 4 second connectors corresponding to each switching node. Among them, there are a total of 4 second connector groups, and each second connector group includes 4 second interface groups.

[0117] In Embodiment 5, in the 2nd cable bridge group, when the 3rd first connector of the 1st computing node is connected to the corresponding second connector, in the second direction, it is not necessary to connect the cable to the first intermediate position (as Figure 7 shown) of the leftmost computing node and switching node of the 2nd cable bridge group, and only need to connect to the second intermediate position (as Figure 7As shown, the distance in the second direction can be shortened from 3X (the distance from A4 to the first intermediate position in the second direction) to 0X (the distance from A4 to the second intermediate position in the second direction). The communication distance between the first connector and the second connector can be reduced, thereby improving the communication quality of the server cabinet.

[0118] In some possible embodiments, based on Embodiment 5, the sorting queues of multiple switching nodes and / or the sorting queues of each second connector of each switching node can be adjusted.

[0119] Based on Embodiment 5, for any cable tray group, the cable tray group includes 3 first connector groups and 3 sets of switching node sets. The switching node set corresponding to the 1st first connector group can be exchanged with the switching node set corresponding to the 3rd first connector group. That is, the order of the switching node set corresponding to the 1st first connector group among the 3 sets of switching node sets is 3; the order of the switching node set corresponding to the 2nd first connector group among the 3 sets of switching node sets is 2; the order of the switching node set corresponding to the 3rd first connector group among the 3 sets of switching node sets is 1.

[0120] Based on Embodiment 5, the number of multiple computing nodes is 16, and there are 4 sets of switching nodes in total; each switching node includes 4 second connectors, and there are 4 second connector groups in total. The second connector group corresponding to the 1st computing node set can be exchanged with the second connector group corresponding to the 4th computing node set, and the second connector group corresponding to the 2nd computing node set can be exchanged with the second connector group corresponding to the 3rd computing node set. That is, the order of the second connector group corresponding to the 1st computing node set among the 4 second connector groups is 2; the order of the second connector group corresponding to the 2nd computing node set among the 4 second connector groups is 1; the order of the second connector group corresponding to the 3rd computing node set among the 4 second connector groups is 4; the order of the second connector group corresponding to the 4th computing node set among the 4 second connector groups is 3.

Specific examples are used herein to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application.
