[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] The core of the present invention is to provide a server system, a data transmission method, a device and a medium to solve the technical problem of how to provide a server supporting hot plugging in a server system with shared hardware.

[0054] With the development of big data, the demand for servers that can provide certain services and computing power to other machines in the network is increasing, the usage scenarios are becoming more and more complex, the requirements for system resources are increasing, and users' requirements for service provision are also increasing. Therefore, higher requirements are placed on server stability, and the difficulty of rapid response to maintenance is also increased.

[0055] The server faces users of the entire network and needs to work 24 / 7 to provide services to users, so it must have extremely high stability. However, even the most stable equipment may have abnormal situations. How to quickly replace new equipment to continue to provide services to users in abnormal situations, and how to reduce the impact on users when the equipment is abnormal, this should be considered during architecture design; but in actual architecture design, many hardware devices are shared and affect each other, and a hardware failure will also cause other devices to stop working. For example, in a dual-node server, each node works independently, and the shared hardware includes hardware units such as fans, network cards, and system status indicators; but when one of the nodes is abnormal, the other node needs to ensure normal operation. In this case, it is necessary to ensure that the normal node does not affect user use, and to quickly restore the faulty node to continue to provide services to users. Therefore, in addition to the shared hardware units, multi-node servers must require that all nodes support hot-swap maintenance.

[0056] In view of this, a node server that supports hot maintenance of nodes is very important. Therefore, the present invention provides a server that supports hot plugging in a server system with shared hardware.

[0057] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. An embodiment of the present invention provides a server system, comprising: at least two nodes, and a common component exists between at least two nodes; a first connection device and a second connection device are provided between the common component and at least one node;

[0058] The first connection device includes a target connector and a gold finger; wherein the target connector is a connector capable of hot plugging of the gold finger;

[0059] The target connector is arranged on the main board of the node; one end of the gold finger is located in the slot of the target connector, the other end of the gold finger is connected to the common component, and the welding wire on the welding wire board of the gold finger is connected to the network interface card;

[0060] The second connection device is a pair of power connectors connected to each other, wherein one power connector is located on the node mainboard and the other power connector is located on the common component;

[0061] The controller on the node is configured to transmit the first signal to the network interface card through the target connector and the bonding wire on the bonding wire board of the gold finger, and to transmit the second signal to the common component through the power connector; wherein the frequency of the first signal is greater than the frequency of the second signal.

[0062] There is no limit on the number of nodes in the server system and the shared components of different nodes, which are determined according to actual conditions. For example, in a dual-node server system, each node works independently, and the shared hardware includes hardware units such as fans, network cards, and system status indicators.

[0063] In order to realize the hot-swappable function of the server, a first connecting device and a second connecting device are provided between the common component and at least one node in an embodiment of the present invention. The first connecting device includes a target connector and a gold finger. Among them, the target connector is a connector that can realize hot-swappable gold fingers. There is no limitation on the target connector used, such as the connector of the GenZ series. The controller on the node is configured to transmit the first signal to the network interface card (NIC) through the welding wires on the welding wire board of the target connector and the gold finger, and to transmit the second signal to the common component through the power connector; wherein the frequency of the first signal is greater than the frequency of the second signal. That is, the first signal is a high-frequency signal, and the second signal is a low-frequency signal. Specifically, the first signal is a signal related to the network interface card; the second signal at least includes a control signal of the hardware in the common component and a signal for obtaining hardware parameters.

[0064] In order to improve the stability and reliability of the system, in implementation, the power connector located on the common component has a sideband signal pin; the controller on the node is configured to transmit the second signal to the common component through the power connector located on the mainboard and the power connector with the sideband signal pin.

[0065] There is no limitation on the network interface card, which can be a first type of network card and / or a second type of network card; wherein the first type of network card is an interface card (MultiHost) that supports multiple nodes sharing a single network, and the second type of network card is an interface card (SingleHost) that supports a single node sharing a single network.

[0066] A first connecting device and a second connecting device are provided between the common component and a preset number of nodes, the preset number being greater than or equal to 2;

[0067] Each node in the preset number of nodes is connected to a first type of network card; wherein, when the number of nodes supported by a single first type of network card is greater than or equal to the preset number, the number of the first type of network card is one; when the number of nodes supported by a single first type of network card is less than the preset number, the number of the first type of network card is multiple;

[0068] Or, each node in the preset number of nodes is respectively connected to a second type of network card; wherein the number of the second type of network cards is equal to the preset number;

[0069] Or, a part of the preset number of nodes are connected to the first type of network card and the remaining number of nodes are connected to the second type of network card; wherein the remaining number is the difference between the preset number and the part of the number; the sum of the number of nodes supported by all the first type of network cards and the number of all the second type of network cards is greater than or equal to the preset number.

[0070] The server system provided by the first embodiment of the present invention is described below by taking the server system including two server nodes as an example. Figure 1 A schematic diagram of a hot-swappable server design based on floating golden finger nodes provided by the first embodiment of the present invention. Figure 1 As shown, there is a common component between node 1 and node 2, and there is a first connection device 1 and a second connection device 2 between node 1 and the common component. Similarly, there is also a first connection device 1 and a second connection device 2 between node 2 and the common component. The first connection device 1 includes a target connector 10 and a gold finger 11. The soldering wire on the soldering wire board of the gold finger is connected to the network interface card; the second connection device 2 is a pair of power connectors, specifically a power connector (male) and a power connector (female).

[0071] Figure 1 In the example, low-speed signals from node 1 and node 2 to common components such as power supply, general purpose input / output (GPIO), inter-integrated circuit (I2C) and other low-speed signals can be connected through the power connector; node 1 and node 2 to the NIC's peripheral component interconnect express (PCIE) and universal serial bus (USB) and related control signals are connected through floating gold fingers + GenZ connector wires.

[0072] The shared components in the dual nodes of the server are connected using a power connector with a Sideband signal PIN: the power supply is provided through the power PIN and GND of the dedicated power connector, the baseboard management controller (BMC) controls the fan control signal of the shared components, and low-speed signals such as temperature acquisition and GPIO go through the Sideband signal PIN of the power connector.

[0073] The shared NIC network part of the dual-node server is connected by placing a GenZ connector on the node motherboard. NIC-related signals such as PCIE signals and USB signals are defined through the standard PIN of the GenZ connector to ensure that the signal integrity (SI) meets the requirements; then the GenZ connector is connected to the corresponding connector or slot of the NIC through the gold finger welding board corresponding to the wire.

[0074] When the NIC uses a MultiHost network card (node ​​one and node two share the same NIC), node one and node two use a Y-type cable from their respective gold finger welding boards to connect to the NIC; when the NIC uses a SingleHost network card (node ​​one and node two have their own independent NIC), node one and node two use a cable from their respective gold finger welding boards to connect to their own independent NICs.

[0075] In order to ensure the normal connection between the gold finger and the target connector, in practice, the size of the ground pin of the gold finger is the same as the size of the pad of the gold finger.

[0076] A locking mechanism is provided in the portion where the gold finger contacts the common component and in the slot of the target connector, and is used to lock the gold finger in a preset position; wherein, when the gold finger is in the preset position, the contact relationship between the gold finger and the target connector is in a fully inserted state.

[0077] The contact relationship between the gold finger and the target connector is divided into a fully inserted (Full Mate) state, an incompletely inserted (De mate) state, and an over-inserted (Over mate) state. Figure 2 The schematic diagram of the positional relationship between the target connector and the golden finger insertion in the first embodiment provided by the present invention. Figure 2 As shown, when the gold finger contacts the mechanical engineering design origin position, it is in a fully inserted state; when the gold finger does not pass through the mechanical engineering design origin position, it is in an incompletely inserted state; when the gold finger exceeds the mechanical engineering design origin position, it is in an over-inserted state.

[0078] The ideal state of the target connector (such as GenZ connector) and the gold finger during the plugging and unplugging process is the Full Mate state, but there will be De mate and Over mate states during the plugging and unplugging process. Due to the existence of De mate and Over mate states, multiple plugging and unplugging are prone to abnormal gold finger contact or connector abnormality risks, so the gold finger is designed with the same length and the mechanism card position is used to ensure that the target connector and the gold finger are in the Full Mate state during plugging and unplugging.

[0079] In addition, in order to avoid damaging the gold finger pad and the target connector due to excessive force during plugging and unplugging, in implementation, the first connecting device also includes a movable mechanism and a fixed plate, and a groove is provided on the fixed plate;

[0080] The soldering wire board of the gold finger is installed on the movable mechanism component, and the floating buckle on the soldering wire board of the gold finger contacts the groove on the fixed plate;

[0081] The floating buckle contacts the groove, which is used to lock the position of the gold finger in the left and right directions when the node is inserted into or removed from the server system;

[0082] The movable mechanism component is used to adjust the position of the gold finger up and down when the node is inserted into or removed from the server system.

[0083] Figure 3 Schematic diagram of a floating solution for a gold finger bonding wire board provided by the first embodiment of the present invention. Figure 3 As shown, it includes a floating buckle 3, a gold finger welding wire board 4 and a fixing plate 5.

[0084] The soldering wire board 4 of the gold finger is installed on a movable mechanism and then fixed as a whole on the fixed plate 5. When the server node is inserted, the target connector is locked in the left and right directions through the stop groove when it contacts the gold finger, and then the gold finger and the movable mechanism adjust the up and down directions to be inserted and adapted with the target connector.

[0085] In the server system provided in the first embodiment, hot-swap blind plugging is realized by floating gold fingers and target adapters; the gold finger design is optimized by optimizing the De mate and Over mate problems between the target connector and the gold fingers during the plugging and unplugging process to ensure that the target connector and the gold fingers are in a Full Mate state during plugging and unplugging; gold finger soldering wire board fixing solution: a floating buckle is used to fix the gold finger soldering wire board floating design solution to ensure that the gold finger and the target connector are not damaged when the direction is offset during the plugging and unplugging process of the server node.

[0086] In addition to the server system described above, in implementation, the first connection device 1 can also be a plurality of pairs of interconnected high-density connectors. One high-density connector in each group of interconnected high-density connectors is located on a node, and another high-density connector in each group of interconnected high-density connectors is located on a common component; and the high-density connector in each group of interconnected high-density connectors located on a common component is connected to a network interface card.

[0087] In a multi-node server system, there are multiple signal transmissions and interactions between nodes and between nodes and shared components, such as PCIE, USB, I2C, GPIO, and power supply. In particular, there are strict requirements on the length of the line and impedance matching in the process of high-speed signal transmission such as PCIE and USB. For example, the rate of PCIE GEN4 is 16 GT / s, and the rate of PCIE GEN5 is 32 GT / s. The rate of each next generation is twice that of the previous generation. However, there are not many types of hot-swappable connectors that can meet the high-speed signal transmission requirements. The main types are Exmax, Xcede, and Impe high-density connectors. Therefore, in the existing solution, the signal transmission between boards and boards is connected, and the signal transmission between boards and backplanes is connected, and a blind plug design is implemented. For example, high-density connectors are used for docking. The server system provided by the second embodiment of the present invention is described below by taking the server system containing two server nodes as an example. Figure 4 This is a schematic diagram of a hot-swappable server design based on a high-density male and female connector docking node provided by the second embodiment of the present invention. Figure 4 As shown, there are common components between node one and node two, and there are first connecting devices 1 and second connecting devices 2 between node one and the common components. Similarly, there are first connecting devices 1 and second connecting devices 2 between node two and the common components. The first connecting device 1 includes two groups of high-density connectors that are interconnected. One high-density connector (high-density connector (male head)) in each group of high-density connectors that are interconnected is located on the node, and another high-density connector (high-density connector (female head)) in each group of high-density connectors that are interconnected is located on the common component; the high-density connector (high-density connector (female head)) on the common component of each group of high-density connectors that are interconnected is connected to the network interface card. The second connecting device 2 is a pair of power connectors, specifically a power connector (male head) and a power connector (female head). Signals from node one or node two to the common components, such as power supply, GPIO, I2C and other low-speed signals, can be connected through the power connector; PCIE and USB high-speed signals and related control signals from node one or node two to the NIC are connected through high-density connector welding wires.

[0088] In the server system provided in this embodiment, hot plugging of the server is achieved by including multiple pairs of high-density connectors connected to each other.

[0089] It is worth noting that the server system provided in the second embodiment adopts a high-speed backplane connector male and female docking design, wherein the high-speed backplane connector has a complex processing technology, is very expensive, and also has great problems in supply.

[0090] The following is a comparative description of the server system provided by the first embodiment and the server system provided by the second embodiment. Figure 5A schematic diagram of cable connection based on a floating golden finger solution provided in the first embodiment of the present invention. Figure 5 In the embodiment, the first connection device 1 composed of the target connector 10 and the gold finger 11 is connected to the target connector 10 and the gold finger 11 located on the network card through a cable. Figure 6 A schematic diagram of a cable connection based on a high-density connector solution provided in the second embodiment of the present invention. Figure 6 In the embodiment, the first connection device 1 composed of the high-speed backplane connector board end 6 and the high-speed backplane connector line end 7 is connected to the high-speed backplane connector line end 7 and the high-speed backplane connector board end 6 on the network card through a cable. For a PCIE X16 NIC adaptation, the required PCIE signal plus the control signal is expected to be about 150 signals, and the required high-density connector size is 4Pair*16. In nodes one and two, the high-density connector->high-density connection welding wire->4 connectors required for NIC (2 for each node). The floating gold finger + GenZ connector design does not change the number of signals. In nodes one and two, the GenZ connector->gold finger welding wire->2 GenZ 4C+ connectors and 2 gold finger welding wire boards required for NIC (1 GenZ 4C+ connector and 1 gold finger welding wire board are required for each node). Since the GenZ 4C+ connector has been mass-produced in the market for a long time and is very commonly used, it has great advantages in cost and supply, and the cost of the welding wire board can be basically ignored. Table 1 is a schematic diagram of the cost of the first embodiment and the cost of the second embodiment.

[0091] Table 1

[0092]

[0093] From the analysis results, it can be seen that the material cost required for the high-density connector solution is 4.3 times that of the floating gold finger solution. When the material cost of the high-density connector design is 1,000 yuan, the floating gold finger solution only requires 232 yuan of material cost. If calculated based on the shipment of 100,000 units, 76.74 million yuan in cost benefits can be saved. Therefore, compared with the solution provided by the second embodiment, the solution provided by the first embodiment can greatly reduce the cost of blind insertion.

[0094] The above describes two design solutions of server systems. This embodiment further provides a data transmission method, which is applied to the above server systems. The method includes:

[0095] Acquire a first signal and a second signal; wherein the frequency of the first signal is greater than the frequency of the second signal;

[0096] The first signal is transmitted to the network interface card through the target connector and the bonding wires on the bonding wire board of the gold finger, and the second signal is transmitted to the common component through the power connector.

[0097] Before transmitting the first signal to the network interface card through the target connector and the bonding wires on the bonding wire board of the gold finger, the method further includes:
