Abstract
Description
Technical Field
[0001] This invention relates to the field of server technology, and more particularly to a dual-node server. Background Technology
[0002] In server architecture, a dual-node system refers to a logical collaborative unit composed of two independent and fully functional server units (i.e., nodes). Through hardware interconnection, software clustering technology, or shared storage links, it integrates computing and storage capabilities and ensures high availability. It is not a single server with two built-in components, but rather the smallest collaborative unit formed by two physically independent servers. Its core principles are redundancy and collaboration, and it is widely used in storage or computing scenarios with high requirements for reliability and continuity.
[0003] In a dual-node server, there are two nodes: an upper node and a lower node. Each node is a system, and structurally, both the upper and lower nodes can be plugged in and removed from the system. However, in the existing technical solution one, if we denote the motherboard of the upper node as Node 1 motherboard and the motherboard of the lower node as Node 2 motherboard, both Node 1 and Node 2 motherboards use B2B connectors (B2B stands for Board-to-Board), and the hard drive backplane also uses B2B connectors, such as... Figure 1 As shown, both the motherboards of Node 1 and Node 2 are interconnected with the PCBA (Printed Circuit Board Assembly) of the hard drive backplane via B2B connectors. However, adopting the above method requires redesigning the motherboard and hard drive backplane, which is costly.
[0004] In the existing technology two for dual-node servers, similarly, if the motherboard of the upper node is denoted as Node 1 motherboard and the motherboard of the lower node is denoted as Node 2 motherboard, as follows: Figure 2 As shown, the motherboards of Node 1 and Node 2 are connected by a center board (which can also be understood as a center backplane). This center board is interconnected with both the motherboards of Node 1 and Node 2, and then interconnected with the hard drive backplane via high-speed cables (specifically, the MCIO signal connector in the center board is connected to the MCIO signal connector in the hard drive backplane via a high-speed cable; MCIO stands for Multi-Lane Connector Interface for Optics and indicates a multi-channel high-speed connector interface). However, adopting the above method requires redesigning the motherboard and center board, which is also costly.
[0005] In the existing technology three of dual-node servers, if we denote the motherboard of the upper node as Node 1 motherboard and the motherboard of the lower node as Node 2 motherboard, both Node 1 and Node 2 motherboards are ordinary motherboards. Ordinary motherboards are commonly used in non-dual-node storage or computing servers, and they are equipped with multiple high-speed connectors such as MCIO, which can connect to devices such as hard drives and PCIe cards (PCIe stands for Peripheral Component Interconnect Express, representing a high-speed serial computer expansion bus standard). Figure 3 As shown, both the motherboards of Node 1 and Node 2 are equipped with high-speed connectors such as MCIO, and the hard drive backplane is also equipped with high-speed connectors such as MCIO. The MCIOs on the motherboards of Node 1 and Node 2 are connected to the MCIOs on the hard drive backplane via high-speed cables, but the plugging and unplugging of the upper and lower nodes cannot be realized.
[0006] As can be seen, in the aforementioned prior art two and prior art three of dual-node servers, the motherboard of the upper node and the motherboard of the lower node must have board-to-board connectors and be connected to the hard drive backplane or the center board. This requires the development of new node motherboards or the modification of existing node motherboards, which increases the cost of obtaining the finished motherboard and the development cycle.

[0024] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.
[0025] Please also refer to Figure 4 and Figure 5 ,in Figure 4 A schematic block diagram of a dual-node server provided in an embodiment of the present invention; Figure 5 This is a schematic block diagram illustrating the functional topology of a dual-node server provided in an embodiment of the present invention. Figure 4 and Figure 5As shown, the dual-node server includes a first server node 10, a second server node 20, a male connector 30, a female connector 40, a hard disk backplane 50, and several hard disks 60. The first server node 10 and the second server node 20 are both connected to the male connector 30 via cables. The male connector 30 is pluggable connected to the female connector 40. The female connector 40 is connected to the hard disk backplane 50 via cables, and the several hard disks 60 are connected to the hard board interface slots of the hard disk backplane 50. The male connector 30 is fixed to the server structure of the first server node 10 and the second server node 20, and the female connector 40 is fixed to the chassis of the hard disk backplane 50.
[0026] In this embodiment, to avoid redesigning or modifying the motherboards of the first server node 10 and the second server node 20 in the dual-node server, a more convenient implementation method can be adopted: the male connector 30 is fixed to the server structure of the first server node 10 and the second server node 20, and the female connector 40 is fixed to the chassis of the hard disk backplane 50. After directly plugging the male connector 30 and its matching female connector 40 to establish a connection, since both the first server node 10 and the second server node 20 are connected to the male connector 30 via cable, and the female connector 40 is connected to the hard disk backplane 50 via cable, both the first server node 10 and the second server node 20 are connected to several hard disks 60 in the hard disk backplane 50, thus achieving interconnection. Furthermore, the first server node 10 and / or the second server node 20 can then be directly disconnected from the male connector 30, thereby achieving decoupling from other components in the dual-node server.
[0027] In one embodiment, such as Figure 4 and Figure 5 As shown, the first server node 10 includes a first motherboard 11, a first power supply 12 and a first MCIO signal connector group 13 disposed on the first motherboard 11; the first MCIO signal connector group 13 is connected to the male connector 30.
[0028] In this embodiment, the first power supply 12 specifically converts externally input AC mains power into low-voltage DC power that can be directly used by the internal components of the device (such as the central processing unit, hard disk, memory, motherboard, etc. of the first server node 10); the first MCIO signal connector group 13 includes multiple MCIO signal connectors. When the first server node 10 adopts the above structure, a cable connection with the male connector is achieved by connecting a cable (such as a high-speed cable) to the first MCIO signal connector group 13. Moreover, the part of the male connector that connects to the first server node can be directly fixed to the first server node without redesigning or modifying the motherboard of the first server node.
[0029] In one embodiment, such as Figure 4 and Figure 5 As shown, the second server node 20 includes a second motherboard 21, a second power supply 22 and a second MCIO signal connector group 23 disposed on the second motherboard 21; the second MCIO signal connector group 23 is connected to the male connector 30.
[0030] In this embodiment, the second server node 20 has the same specific structure as the first server node 10. Similarly, the second power supply 22 specifically converts the externally input AC mains power into low-voltage DC power that can be directly used by the internal components of the device (such as the central processing unit, hard disk, memory, motherboard, etc. of the second server node 10); the second MCIO signal connector group 23 includes multiple MCIO signal connectors. When the second server node 20 adopts the above structure, a cable connection with the male connector is achieved by connecting a cable (such as a high-speed cable) to the second MCIO signal connector group 23. Moreover, the part of the male connector that connects to the second server node can be directly fixed to the second server node without redesigning or modifying the motherboard of the second server node.
[0031] In one embodiment, such as Figures 4-11 As shown, the male connector 30 includes a first male connector 31, a second male connector 32, a first male connector structure 33, a second male connector structure 34, a first high-speed cable 35, and a second high-speed cable 36. The first male connector 31 is fixed on the first male connector structure 33 and is connected to the first MCIO signal connector group 13 of the first server node 10 through the first high-speed cable 35. The second male connector 32 is fixed on the second male connector structure 34 and is connected to the second MCIO signal connector group 23 of the second server node 20 through the second high-speed cable 36.
[0032] In this embodiment, the first male connector structure 33 and the second male connector structure 34 are designed separately rather than as a single unit. When the first male connector 31 is fixed to the first male connector structure 33 and the second male connector 32 is fixed to the second male connector structure 34, the first male connector structure 33 can be fixed to the first server node 10 and the second male connector structure 34 can be fixed to the second server node 20, respectively.
[0033] In one embodiment, such as Figures 5-11 As shown, the first terminal 35A of the first high-speed cable 35 is fixed on the first server node 10, and the first cable connector 35B and the second cable connector 35C of the first high-speed cable are both connected to the first MCIO signal connector group 13 of the first server node 10; wherein, the first terminal 35A is connected to the first male connector 31. The second terminal 36A of the second high-speed cable 36 is fixed on the second server node 20. The third cable connector 36B and the fourth cable connector 36C of the second high-speed cable 36 are both connected to the second MCIO signal connector group 23 of the second server node 20. The second terminal 36A is connected to the second male connector 32.
[0034] In this embodiment, if the first MCIO signal connector group 13 is considered as the female end, and the end of the first high-speed cable 35 connected to the first MCIO signal connector group 13 (including the first cable connector 35B and the second cable connector 35C) is considered as the male end, the first terminal 35A can also be considered as the male end (the first terminal 35A can specifically use a B2B connector). The first high-speed cable 35 as a whole can be considered as a high-speed cable with two male ends. Moreover, the first terminal 35A is fixed on the first server node 10, and it adopts a detachable fixed connection method. Afterwards, the first terminal 35A can be removed from the first server node 10 according to actual needs to complete operations such as maintenance and replacement.
[0035] Similarly, if the second MCIO signal connector group 23 is considered as the female end, and the end of the second high-speed cable 36 connected to the second MCIO signal connector group 23 (including the third cable connector 36B and the fourth cable connector 36C) is considered as the male end, the second terminal 36A can also be considered as the male end (the second terminal 36A can specifically use a B2B connector). The second high-speed cable 36 as a whole can also be considered as a high-speed cable with two male ends. Moreover, the second terminal 36A is fixed on the second server node 10, and it adopts a detachable fixed connection method. Afterwards, the second terminal 36A can be removed from the second server node 20 according to actual needs to complete operations such as maintenance and replacement.
[0036] In one embodiment, such as Figures 4-11 As shown, the first male connector structure 33 is fixed on the first server node 10, and the second male connector structure 34 is fixed on the second server node 20.
[0037] In this embodiment, in order to indirectly mount the first male connector 31 onto the first server node 10, the first male connector structure 33 can be used as a mounting base for the first male connector 31 and mounted onto the first server node 10. Similarly, in order to indirectly mount the second male connector 32 onto the second server node 20, the second male connector structure 34 can be used as a mounting base for the second male connector 32 and mounted onto the second server node 20.
[0038] In one embodiment, such as Figures 4-11 As shown, the female connector 40 includes a first female connector 41, a second female connector 42, a female connector structure 43, a third high-speed cable 44, and a fourth high-speed cable 45; the first female connector 41 and the second female connector 42 are fixed on the female connector structure 43; the first female connector 41 is connected to the hard disk backplane 50 through the third high-speed cable 44, and the second female connector 42 is connected to the hard disk backplane 50 through the fourth high-speed cable 45.
[0039] In this embodiment, to avoid redesigning or modifying the hard drive backplane, a more convenient implementation method can be adopted, namely, fixing the female connector 40 to the chassis of the hard drive backplane 50. More specifically, as... Figures 4-11 As shown, the third terminal 44A of the third high-speed cable 44 is fixed on the hard disk backplane 50, and the fifth cable connector 44B and the sixth cable connector 44C of the third high-speed cable 44 are both connected to the third MCIO signal connector group of the hard disk backplane 50; wherein, the third terminal 44A is connected to the first female connector 41. The fourth terminal 45A of the fourth high-speed cable 45 is fixed on the hard disk backplane 50. The seventh cable connector 45B and the eighth cable connector 45C of the fourth high-speed cable 45 are both connected to the fourth MCIO signal connector group of the hard disk backplane 50. The fourth terminal 45A is connected to the second female connector 41.
[0040] If the third MCIO signal connector group is considered as the female end, and the end of the third high-speed cable 44 connected to the third MCIO signal connector group (including the fifth and sixth cable connectors, both of which can be B2B connectors) is considered as the male end, and the third terminal is also considered as the female end (the third terminal can specifically use multiple MCIO signal connectors), the third high-speed cable 44 as a whole can be considered as a high-speed cable with both male and female ends. Furthermore, the female connector structure 43 is fixed to the hard drive backplane 50 using a detachable fixed connection method. It can then be removed from the hard drive backplane 50 for maintenance, replacement, or other operations as needed.
[0041] Similarly, if the fourth MCIO signal connector group is regarded as the female end, and the end of the fourth high-speed cable 45 connected to the fourth MCIO signal connector group (including the seventh cable connector 45B and the eighth cable connector 45C, both of which can be B2B connectors) is regarded as the four terminals, multiple MCIs can be used as the male ends of the cable, and the fourth terminal can also be regarded as the female end of the cable (the O signal connector), the fourth high-speed cable 45 as a whole can be regarded as a high-speed cable with male and female ends.
[0042] In one embodiment, such as Figures 4-11 As shown, the hard disk backplane 50 is provided with a third MCIO signal connector group 51 and a fourth MCIO signal connector group 52; the first female connector 41 is connected to the third MCIO signal connector group 51 through the third high-speed cable 44, and the second female connector 42 is connected to the fourth MCIO signal connector group 52 through the fourth high-speed cable 45.
[0043] In this embodiment, the hard disk backplane 50 is provided with a third MCIO signal connector group 51 and a fourth MCIO signal connector group 52. In specific implementations, both can use seven 8-interface MCIO signal connectors. The first female connector 41 is connected to the third MCIO signal connector group 51 through the fifth and sixth cable connectors on the male end of the third high-speed cable 44. The second female connector 42 is connected to the fourth MCIO signal connector group 52 through the seventh and eighth cable connectors on the male end of the fourth high-speed cable 45. Through this connection method, flexible connection between the female connectors and the hard disk backplane can be achieved.
[0044] In one embodiment, such as Figure 4 and Figure 5 As shown, the female connector structure 43 is fixed on the hard disk backplate 50.
[0045] In this embodiment, the female connector structure 43 in the female connector 40 is fixedly connected to the hard disk backplane 50. Unlike the male connector 30, which uses a split design for the first male connector structure 33 and the second male connector structure 34, the female connector structure 43 adopts a complete structure without the need for a split design.
[0046] In one embodiment, such as Figures 4-11 As shown, the third MCIO signal connector group 51 and the fourth MCIO signal connector group 52 are all connected to a plurality of hard drives 60 connected to the hard drive backplane 50.
[0047] In this embodiment, if the plurality of hard disks 60 connected to the hard disk backplane 50 are specifically implemented as multiple hard disks, and all multiple hard disks are plugged into the hard disk interface slots of the hard disk backplane, the first server node 10 and the second server node 20 establish connections with the multiple hard disks through the male connector 30, the female connector 40, and the hard disk backplane 50, so that the first server node 10 and the second server node 20 can use the data of the same hard disk or different hard disks, realizing the data processing effect of a dual-node server.
[0048] The dual-node server in this application will now be described in detail with reference to a more specific embodiment.
[0049] like Figures 4-11 As shown, both the first server node 10 and the second server node 20 can use an x86 platform CPU (i.e., central processing unit). The CPU of the first server node 10 is also connected to the first baseboard management controller (i.e., the first BMC, where BMC stands for Baseboard Management Controller), and the CPU of the second server node 20 is also connected to the second baseboard management controller. In specific implementations, input / output devices can be connected to the CPUs of the two server nodes according to actual usage requirements. Moreover, the CPU of the first server node 10 is specifically connected to the first MCIO signal connector group 13 via a PCIeGen5.0 bus, and the CPU of the second server node 20 is specifically connected to the second MCIO signal connector group 23 via a PCIeGen5.0 bus and a 25Gb RoCE interface module (which provides four SFI buses with a transmission rate of 25Gbit / s, mainly used for the connection of front-end services between storage devices and application servers).
[0050] In summary, this invention discloses a dual-node server, comprising a first server node, a second server node, a male connector, a female connector, a hard disk backplane, and a plurality of hard disks. Both the first and second server nodes are connected to the male connector via cables, the male connector and the female connector are pluggable, and the female connector is connected to the hard disk backplane via a cable. The plurality of hard disks are connected to the hard board interface slots on the hard disk backplane. The male connector is fixed to the server structure of the first and second server nodes, and the female connector is fixed to the chassis of the hard disk backplane. In this dual-node server embodiment, the first and second server nodes can be connected to the hard disk backplane via male-female terminal plug-in and cable connections without modifying the motherboard structure. Furthermore, the first and second server nodes are flexibly pluggable to achieve connection or decoupling.

Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention.
