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

[0024] Figure 1 This is a schematic diagram of the structure of a server cabinet provided in an embodiment of the present application. Figure 1 The server cabinet may include multiple computing nodes, multiple switching nodes, a power distribution unit (PDU), and a cooling unit. The height of the server cabinet may be between 42U and 47U, 1U may represent a rack unit, and the height of a rack unit may be 1.75 inches (about 4.45 cm), which may also be adjusted according to actual conditions without specific restrictions.

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

[0026] See also Figure 1 The front structure of the server cabinet can be increased by rack reinforcements to increase the structural strength and stability of the server rack. The rack reinforcements are deployed on both sides of multiple computing nodes and multiple switching nodes. One rack reinforcement occupies 1U of height. A cooling unit can be deployed at the bottom of the server cabinet. The cooling unit can cool the server cabinet and occupy 4U of the height of the server cabinet. Two PDUs can also be deployed in the server cabinet. The PDU can provide power to the server cabinet and one PDU occupies 2U of height. 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] See also Figure 1The back structure of the server cabinet can include bus duct, manifold and Cable Tray (cable bridge). The power distribution unit is connected to the bus duct to supply power to the server cabinet. The cooling unit controls the water inlet and outlet of the manifold, which is the liquid path for liquid cooling of the server cabinet. Cable Tray (cable bridge) is used to connect the high-speed signals of the computing nodes and the switching nodes according to the designed topological interconnection relationship. It is worth noting that Figure 1 The bus duct, manifold and cable tray position structures shown are only examples, and the positions and quantities can be adjusted according to actual conditions.

[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 a corresponding switching node. In the intermediate layer, multiple switching nodes can be designed as a fully interconnected design to form a network topology. Then, through the network topology corresponding to the switching node, it can be ensured that each computing node can be interconnected with any other computing node in the cabinet to achieve full interconnection of computing nodes.

[0029] A plurality of first connectors may be provided at the back end of the computing node, and a plurality of second connectors may be provided at the back end of the switching node. The first connector of the computing node may be connected to the second connector of the switching node via a high-speed cable. The connector may be a high-speed connector, which is a connector for high data rate transmission, and the high-speed connector may be used to support 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 vertically, and each computing node may include multiple first connectors, and the multiple first connectors are arranged horizontally. Multiple switching nodes are arranged vertically, and each switching node includes multiple second connectors, and the multiple second connectors are arranged horizontally. For any computing node, the multiple connectors of the computing node are respectively connected to the first column connectors of the multiple switching nodes. When the computing node and the switching node are far apart, the cable length between the first connector of the computing node and the second connector of the switching node is long, resulting in low communication quality.

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

[0032] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] In conjunction with the specific application environment architecture or specific hardware architecture on which the server cabinet provided in this application relies, the specific application environment architecture or specific hardware architecture is described here.

[0034] Figure 2A This is a schematic diagram of the structure of a server cabinet provided in an embodiment of the present application. Figure 2A The server cabinet includes 16 computing nodes and 12 switching nodes, the computing nodes are computing nodes 1-16, and the switching nodes are switching nodes 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, and each second connector can be provided with two second connector interfaces. Among them, the letters AH, JN, and PR indicate the 1st to 16th computing nodes, and the Arabic numerals 1-6 indicate the 1st to 6th first connectors, then A1 can indicate the 1st first connector of the 1st computing node, A2 indicates the first connector of the 1st computing node, ..., R6 indicates the 6th first connector of the 16th computing node, as shown in Table 1 below, wherein computing nodes 1-16 indicate the 1st computing node to the 16th computing node, and first connectors 1-6 indicate the 1st first connector to the 6th first connector.

[0035] Table 1

[0036]

[0037] See also Figure 2A In the 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 located on the upper side of the 12 switching nodes, and the 9th to 16th computing nodes are located on the lower side of the 12 switching nodes, so that the 12 switching nodes are centrally placed.

[0038] The arrangement direction of the plurality of computing nodes and the plurality of switching nodes is a first direction, and the second direction is perpendicular to the first direction. Figure 2A , multiple computing nodes and multiple switching nodes are arranged longitudinally, that is, the longitudinal arrangement direction is a first direction. The second direction is perpendicular to the first direction. In the second direction, each computing node can be provided with multiple first connectors, and each switching node can be provided with multiple second connectors.

[0039] See also Figure 2A, the first connector of each computing node is provided with two first connector interfaces, and the two first connector interfaces can be respectively connected to the second connectors of the two switching nodes; at the same time, two connector interfaces are provided in each second connector, and the second connector can also be respectively connected to the first connectors of the two computing nodes through the two connector interfaces. 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 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 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; other connections are similar. Figure 1 Other cable connections are omitted, and only a group of cables connected to the first connector A1 is shown. The identification 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 identification. For example, the identification 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 identification 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 ratio between the first connector and the second connector can also be a 3:3 matching ratio, a 4:4 matching ratio, or other matching ratios. In the present application, a 2:2 matching ratio is used as an example for explanation.

[0042] See also Figure 2A ,When multiple switching nodes are placed in the middle, the computing nodes in the upper half and the computing nodes in the lower half are in a center-symmetric relationship, ,such as Figure 2A The topology and length of the cables connecting the upper and lower symmetrical computing nodes and switching nodes are also the same. 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 explained so that technicians in this technical field can better understand the present application solution.

[0043] Figure 2B A schematic diagram of a connector distance provided in an embodiment of the present application. Figure 2B, the direction from the 1st first connector to the 6th first connector is the second direction, and the direction from the 1st computing node to the 16th computing node is the first direction.

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

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

[0046] See also Figure 2B , when the first connectors of the first computing node and the second computing node are connected to the second connectors of the plurality of switching nodes, the cable can be connected to the left side of the first first connector in the second direction, and then connected to the second connector of the switching node in the first direction; when the first connectors of the second computing node and the fourth computing node are connected to the second connectors of the plurality of switching nodes, the cable can be connected to the middle of the first first connector and the second first connector in the second direction, and then connected to the second connector of the switching node in the first direction; when the first connectors of the fifth computing node and the sixth computing node are connected to the second connectors of the plurality of switching nodes, the cable can be connected to the middle of the second first connector and the third first connector in the second direction, and then connected to the second connector of the switching node in the first direction; when the first connectors of the seventh computing node and the eighth computing node are connected to the second connectors of the plurality of switching nodes, the cable can be connected to the right side of the third first connector in the second direction, and then connected to the second connector of the switching node in the first direction. 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 first computing node and the twelfth switching node as an example, the distance between the sixth first connector A6 of the first computing node and the first second connector of the twelfth switching node is 5X+19Y.

[0047] The connection between the first connector and the second connector, and the distance determination method, are only an example provided by the present application to facilitate understanding of the present application. Other connection and distance determination methods will not affect the embodiments of the present application and are also within the scope of protection of the present application.

[0048] Table 2

[0049]

[0050] It is worth noting that the total cable length of all cables in the first direction is fixed, and the total cable length in the first direction will not change after the positions of the multiple second connectors of the switching node are adjusted.

[0051] For example, in the first direction, the distances between the first second connectors of the 1st to 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 connector of the 1st to 7th computing nodes are Y, 2Y, 3Y, 4Y, 5Y, 6Y, 7Y, 8Y, respectively. When the arrangement position of the first switching node is interchanged with the arrangement position of the second switching node, the corresponding distances with the first connector 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, and the total cable length in the second direction will not change after adjusting the positions of the multiple second connectors of the switching node.

[0053] Based on the above analysis, in the server cabinet provided in the embodiment of the present application, each computing node is provided with a plurality of first connectors in the second direction, and the plurality of first connectors of each computing node constitute a plurality of first connector groups in the first direction; each switching node is provided with a plurality of second connectors in the second direction, and the plurality of second connectors of each switching node constitute a plurality of second connector groups in the first direction; the plurality of switching nodes include a plurality of switching node sets, and each first connector group has a one-to-one correspondence with each switching node set; the plurality of computing nodes include a plurality of computing node sets, and a plurality of second connector groups have a one-to-one correspondence with a plurality of computing node sets. There is at least one set of switching node sets whose arrangement position in the plurality of switching node sets is inconsistent with the arrangement position of the first connector group corresponding to it in the plurality of first connector groups, or / and there is at least one second connector group whose arrangement position in the plurality of computing node sets is inconsistent with the arrangement position of the computing node set corresponding to it, 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 switching node sets, there is a one-to-one correspondence between the M first connector groups and the M switching node sets, and M is an integer greater than 1.

[0055] See also Figure 2AIn the server cabinet, N is 16 and M is 6. There are 16 computing nodes in the server cabinet, and each computing node corresponds to 6 first connectors, and there are 6 first connector groups in total. The first first connector group includes the first first connectors of the 16 computing nodes, which are respectively the first first connector corresponding to the first computing node, the first first connector corresponding to the second computing node, ..., the first first connector corresponding to the 16th computing node (i.e., A1-H1, J1-N1, P1-R1); the second first connector group includes the second first connectors of the 16 computing nodes, which are respectively the second first connector corresponding to the first computing node, the second first connector corresponding to the second computing node, ..., the 12th first connector corresponding to the 16th computing node (i.e., A2-H2, J2-N2, P2-R2); the third first connector group includes the third first connectors of the 16 computing nodes, which are respectively the third first connector corresponding to the first computing node, the third first connector corresponding to the second computing node, ..., the third 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 the 16 computing nodes, which are 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 the 16 computing nodes, which are 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 the 16 computing nodes, which are 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] See also Figure 2A There are 6 groups of switching node sets in the server cabinet, among which the 1st group of switching node sets includes the 1st switching node and the 2nd switching node; the 2nd group of switching node sets includes the 3rd switching node and the 4th switching node; the 3rd group of switching node sets includes the 5th switching node and the 6th switching node; the 4th group of switching node sets includes the 7th switching node and the 8th switching node; the 5th group of switching node sets includes the 9th switching node and the 10th switching node; and the 6th group of switching node sets includes the 11th switching node and the 12th switching node.

[0057] For example, the correspondence between the first connector group and the first switch node set is shown in Figure 2A , the 16th first connector (A1) of the first first connector group corresponds to the first set of switch nodes (the second connector of the first switch node and the second connector of the second switch node), and the other first connectors have a one-to-one correspondence with the corresponding switch node groups. Figure 2A The description in will not be repeated here.

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

[0059] See also Figure 2A , in the server cabinet, N is 16 and M is 6. There are 16 computing nodes and 8 second connector groups, 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, which are the first second connectors of 12 switching nodes, respectively. Each second connector can be connected to 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 of the first computing node and the first first connector B1 of the first computing node. Figure 2A In the example, the first second connector of the first switching node marks the identifier A1 of the first first connector of the first computing node and the identifier B1 of the first first connector of the first computing node. The eight computing node sets and the eight second connector sets have a one-to-one correspondence relationship, which can be seen in Figure 2A , I will not go into details 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 plurality of switching nodes may be used to indicate the left side of the plurality of switching nodes, and the other side of the plurality of switching nodes may be used to indicate the right side of the plurality of switching nodes; or, one side of the plurality of switching nodes may be used to indicate the upper side of the plurality of switching nodes, and the other side of the plurality of switching nodes may be used to indicate the lower side of the plurality of switching nodes.

[0062] For example, see Figure 2AThe first computing node group may be computing nodes 1-8, the second computing node group may 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 the present application, multiple computing nodes are divided into a first computing node group and a second computing node group, and are arranged on both sides of multiple switching nodes. This can shorten the distance between the first connector and the second connector in the first direction, thereby reducing the communication distance and improving the communication quality of the server cabinet.

[0064] Hereinafter, the server cabinet improved in the present application is described by taking one side of the multiple switching nodes as the upper side of the multiple switching nodes and the other side of the multiple switching nodes as the lower side of the switching nodes.

[0065] In the first embodiment provided by the present application, when the layout of multiple switching nodes in the first direction remains unchanged, the positions of the second connectors in the second direction are adjusted, and the arrangement positions of at least one second connector group and its corresponding computing node set are inconsistent.

[0066] In some possible embodiments, the computing node with the longest cable in the first direction has the shortest cable in the second direction, so as to reduce the maximum connection distance between the first connector and the second connector.

[0067] By adjusting the position of the second connector in the switching node, the arrangement position of at least one second connector group and its corresponding computing node set can be inconsistent, so that the distance between any first connector and the corresponding second connector after adjustment is less than the maximum connection distance, thereby reducing the extreme signal transmission distance and improving the quality of server cabinet communication.

[0068] Specifically, the number of the plurality of computing nodes is N, each switching node includes N second connector interfaces, each second connector includes K second connector interfaces, N is an integer greater than 1, K is an integer greater than 1, wherein each switching node includes A second connector, a plurality of computing nodes including There is at least one second connector group and its corresponding computing node set whose arrangement position is inconsistent, which is used to indicate: The sorting queue of the second connector group, and the corresponding The sorting queues of the computing node sets are inconsistent. Figure 3 , the server cabinet provided in Example 1 of the present application is specifically described.

[0069] Figure 3 This is a schematic diagram of the structure of a server cabinet provided in Example 1 of the present application. Figure 3 The server cabinet includes 16 computing nodes (ie, N is 16) and 12 switching nodes, the computing nodes are computing nodes 1-16, and the switching nodes are switching nodes 1-12. Each computing node includes 6 first connectors, each switching node includes 8 second connectors, and K is 2.

[0070] There are 8 computing node sets among the 16 computing nodes, among which the first computing node set is the first computing node and the second computing node, the second computing node set is the third computing node and the fourth computing node, the third computing node set is the fifth computing node and the sixth computing node, the fourth computing node set is the seventh computing node and the eighth computing node, the fifth computing node set is the ninth computing node and the tenth computing node, the sixth computing node set is the eleventh computing node and the twelfth computing node, the seventh computing node set is the thirteenth computing node and the fourteenth computing node, and the eighth computing node set is the fifteenth computing node and the sixteenth computing node.

[0071] There are 8 second connector groups in total, and each second connector group includes 12 second connectors. The first second connector group includes the first second connectors of the 12 switching nodes, the second second connector group includes the second second connector group of the 12 switching nodes, the third second connector group includes the third second connector of the 12 switching nodes, the fourth second connector group includes the fourth second connector of the 12 switching nodes, the fifth second connector group includes the fifth second connector of the 12 switching nodes, the sixth second connector group includes the sixth second connector of the 12 switching nodes, the seventh second connector group includes the seventh second connector of the 12 switching nodes, and the eighth second connector group includes the eighth second connector of the 12 switching nodes.

[0072] The 8 computing node sets correspond one-to-one to the 8 second connector groups. The specific correspondence is that the 1st computing node set corresponds to the 1st second connector group, the 2nd computing node set corresponds to the 2nd second connector group, and so on. The 8th computing node set corresponds to the 8th second connector group.

[0073] In the second direction, the order of the second connector set inside each switching node can be swapped so that the connection that is too long in the first direction can be shortened in the second direction to meet the requirement of reducing the distance between the first connector and the second connector.

[0074] In some possible embodiments, the second connector group corresponding to the first computing node set can be swapped with the second connector group corresponding to the fourth computing node set, and the second connector group corresponding to the fifth computing node set can be swapped with the second connector group corresponding to the eighth computing node set.
