Description

Technical Field

[0001] The present invention relates to the technical field of servers, and in particular to a server control method, server, equipment, medium and product based on a network card. Background Art

[0002] With the application of technologies such as big data and artificial intelligence, data has grown exponentially in recent years. As a result, traditional servers with only CPU (Central Processing Unit) as the data processing core cannot meet data processing needs. AI (Artificial Intelligence) servers equipped with GPU (Graphics Processing Unit) came into being.

[0003] For AI servers, some leading manufacturers in the AI ​​field have launched AI server architecture specifications based on their own needs, such as the MGX (Modular GPU Acceleration PlatformMGX) specification. The architecture specifications make detailed requirements for the specifications and models of various physical interfaces and signal definitions in the server, and other server manufacturers are not allowed to modify them.

[0004] When designing AI servers, in order to meet the needs of different customer groups, it is necessary to make the servers compatible with smart network cards from different manufacturers. However, each Internet manufacturer currently has its own self-developed smart network card model. Each manufacturer has developed a custom design based on the specifications according to its own needs. The form specifications, bus types, and signal definitions of each manufacturer are diverse and not completely unified. Moreover, specifications such as MGX are defined based on the manufacturer's own smart network card, without considering the actual situation of the self-developed smart network cards of other domestic manufacturers. This makes the compatibility of smart network cards face great challenges when designing AI servers based on specifications such as MGX. Summary of the invention

[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all 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.

[0029] In related technologies, a variety of different riser cards (adapter cards) are developed to meet the different signal requirements of smart network cards from different manufacturers, and they are used in a one-to-one combination (riser card and smart network card). However, the AI ​​server is a relatively complex system. Replacing boards is time-consuming and labor-intensive. Reassembling the machine may cause other problems caused by improper operation, which increases the maintenance cost of the machine. At the same time, R&D needs to design multiple boards to meet the needs of different scenarios, increasing R&D, production and system maintenance costs. Moreover, the existing boards do not meet the requirements of MGX and other specifications, and the relevant boards cannot be used on the server.

[0030] In the embodiments of the present invention, in view of the problem that there are many types of smart network cards and the board replacement steps are complicated, the operation is cumbersome, and time-consuming and labor-intensive, a special hardware architecture design and different cables can be used to easily achieve the compatible design of smart network cards of different forms from multiple manufacturers without time-consuming and labor-intensive operations on the basis of minor changes, thereby avoiding the separate development of multiple models of riser boards, greatly saving server development costs and maintenance costs, and improving development and maintenance efficiency. Moreover, since the MGX and other architecture specifications strictly define the connectors and signal definitions of the motherboard, the embodiments of the present invention can implement this function on the existing connectors without violating the MGX and other architecture specifications.

[0031] In the embodiment of the present invention, a complete solution is provided in the hardware architecture design, logic design, and cable design, and a truth table with identification uniqueness is provided (as shown in Table 2 below), so that the type identification and in-place judgment of multiple types of smart network cards can be completed. By utilizing the native NCSI (Network Controller Sideband Interface, a network interface protocol) connector signal definition of MGX and other specifications, different configuration requirements can be met through simple cable design and logic processing without violating the specifications, which can effectively solve the compatibility design problems of smart network cards of various manufacturers of AI servers under MGX and other architecture specifications, and greatly expand the configuration diversity of AI servers. In addition, compared with the traditional method of making multiple riser boards, it saves more time, and will not cause other problems due to tedious operation steps such as replacing boards, which greatly improves maintenance efficiency and reduces R&D and production costs.

[0032] Specifically, in terms of hardware architecture design, three signals at the NCSI connector in the MB (Main Board) need to be specially processed without violating the MGX and other specification definitions, and a complete hardware topology architecture is given between the MB, SW (Switch) board, and FAN (fan) board. Logically, a truth table with unique identification is given, based on which the type identification and in-place judgment of multiple types of smart network cards can be completed. In terms of cable design, a variety of specific types of cables are given based on the identified smart network card type, and the signal processing method in the cable design is detailed.

[0033] The following is further described with reference to the accompanying drawings:

[0034] Reference Figure 1 , shows a flow chart of the steps of a server control method based on a network card provided by some embodiments of the present invention. In some instances, the server may be an AI server, such as an AI server based on the MGX specification. The AI ​​server may be equipped with a CPU and a GPU. The network card may be an intelligent network card. Compared with a non-intelligent network card, an intelligent network card may undertake some data processing functions. Specifically, the following steps may be included:

[0035] Step 101, obtaining level signals transmitted by a plurality of signal lines of a first connector in the server mainboard, wherein one end of the plurality of signal lines is set to be grounded or suspended according to a network card connection condition of a riser card in the mainboard.

[0036] In practical applications, such as Figure 2 , Figure 3 , Figure 4 The server is provided with a mainboard (MB), the network card is connected to the mainboard through a riser card, the mainboard is provided with a first connector, the first connector is an NCSI connector, and the first connector is provided with multiple signal lines for transmitting different signals.

[0037] In order to be compatible with different smart network cards, detect whether the network card is online and distinguish different types of network cards, multiple signal lines can be grounded or suspended at one end of the first connector to generate different level signals, such as generating a low level signal when grounded and generating a high level signal when suspended. Then, through the arrangement and combination of signals generated by multiple signal lines, the server can know the specific connection status of the network card, such as which adapter card is connected to the network card and the type of the connected network card.

[0038] In some examples, the types of network cards may include smart network cards that support a single processor (Single-host) (i.e., X16 smart network cards, whose PCIe X16 signals only need to be provided by a single CPU), smart network cards that support multiple processors (Muti-host) (i.e., X8X8 smart network cards, which require two CPUs in the system to each provide a PCIe X8 signal), and non-smart network cards (i.e., ordinary network cards).

[0039] In some embodiments of the present invention, obtaining level signals transmitted by multiple signal lines of a first connector in a server mainboard includes: obtaining a first level signal transmitted by a first signal line of the first connector in the server mainboard, the first signal line being used to transmit a level signal of whether the adapter card is connected to a network card; obtaining a second level signal transmitted by a second signal line of the first connector in the server mainboard, the second signal line being used to transmit a level signal of a network card type of the network card connected to the adapter card.

[0040] In actual applications, different signal lines in the first connector can transmit different signals, which mainly include two categories. The first signal line is used to transmit a level signal of whether the adapter card is connected to the network card, that is, it is used for in-place judgment, such as through PRESENCE_N and SEC_NIC_PRSNT_N signals to perform in-place judgment. The second signal line is used to transmit a level signal of the network card type of the network card to which the adapter card is connected, that is, it is used to distinguish which type of smart network card it is, such as through the NIC_BW_ID signal to distinguish the type of smart network card.

[0041] In some embodiments of the present invention, the mainboard is provided with one or more riser cards. When the mainboard is provided with multiple riser cards, the first connector transmits level signals of whether different riser cards are connected to the network card through different first signal lines. For example, the first connector transmits PRESENCE_N and SEC_NIC_PRSNT_N through the first signal line, PRESENCE_N is used to identify whether the first riser card is connected to the network card, and SEC_NIC_PRSNT_N is used to identify whether the second riser card is connected to the network card.

[0042] In practical applications, different signal lines may correspond to different pins of the first connector for transmitting different signals. MGX and other specifications have made detailed definitions of the MB-side NCSI connector, as shown in Table 1, including signals such as RBT, UART, PRESENCE, and PKG_ID.

[0043]

[0044] Table 1

[0045] In actual applications, the PRESENCE signal is the smart NIC presence signal, which is grounded by default on the smart NIC side. When the NCSI cable is installed properly, the MB side recognizes that this signal is low and knows that there is a smart NIC in the current system. This leads to a series of design problems and limits the configuration implementation of the server, as follows:

[0046] 1. There is only one NCSI connector on the MB side of the server, but the system configuration requires support for 1 or 2 smart network cards.

[0047] 2. When one smart network card is configured (only one smart network card is inserted in Riser 0), Riser 1 needs to install a common network card to maximize the utilization of system resources. However, the power supply and heat dissipation solutions of common network cards and smart network cards are different.

[0048] 3. Smart NICs are divided into two types: X8X8 (i.e., smart NICs that support a single processor) and X16 (i.e., smart NICs that support multiple processors). The system cannot accurately know the status of the card.

[0049] In the embodiment of the present invention, without changing the original definition of the MGX specification, a cable-assisted method is adopted to fully utilize the PKG_ID 0 / 1 signal to achieve the system design goal.

[0050] In the relevant specification definition, the PKG_ID 0 / 1 signal is the signal output by the MB to the smart network card, which is used to configure the ID of the smart network card. It should be noted that the PKG_ID 0 / 1 signal is not a changing signal, its state is always high or low, and other manufacturers' smart network cards do not need this signal.

[0051] Therefore, when designing the cable, choose to loopback the MB end of the PKG_ID 0 / 1 signal to GND (grounding) or leave it floating, and use it as SEC_NIC_PRSNT_N (the second smart NIC is in place) and NIC_BW_ID (used to distinguish between X8X8 and X16 smart NICs), respectively, and loopback to GND at the smart NIC connector. This can implement the relevant functions defined for the smart NIC, while satisfying the MB end's identification and distinction of multiple types of smart NICs.

[0052] That is to say, in the original definition of MGX and other specifications, the PRESENCE signal in the NCSI connector is used to identify whether the first network card is in place. By looping back the MB end of this PKG_ID 0 / 1 signal to GND (ground) or leaving it floating, two other signals can be formed, namely SEC_NIC_PRSNT_N and NIC_BW_ID. SEC_NIC_PRSNT_N is used to identify whether the second network card is in place, and NIC_BW_ID is used to distinguish between X8X8 and X16 smart network cards.

[0053] Through the above settings, one end of the signal line can be set to ground or suspended according to the network card connection status of the adapter card in the motherboard, thereby realizing the presence judgment of at least two network cards and distinguishing the network card types of the network cards in place, thereby improving the server's compatibility with smart network cards.

[0054] Step 102: Determine, based on the level signals transmitted by the plurality of signal lines, whether the adapter card in the mainboard is connected to a network card and the type of the network card to which the adapter card is connected.

[0055] In some embodiments of the present invention, determining whether the adapter card in the mainboard is connected to a network card and the type of the network card to which the adapter card is connected according to the level signals transmitted by the multiple signal lines includes:

[0056] According to the first level signal, it is determined whether the adapter card in the mainboard is connected to the level signal of the network card; according to the second level signal, the type of the network card connected to the adapter card is determined.

[0057] In some embodiments of the present invention, the network card type includes any one of the following: a smart network card supporting a single processor, a smart network card supporting multiple processors, and a non-smart network card.

[0058] In some embodiments of the present invention, the network card type includes a smart network card that supports a single processor; when the network card connected to the adapter card is a smart network card that supports a single processor, one end of the first signal line is set to ground, and the first level signal is a low level signal; when the network card connected to the adapter card is a smart network card that supports a single processor, one end of the second signal line is set to ground, and the second level signal is a low level signal.

[0059] In some embodiments of the present invention, the network card type includes an intelligent network card that supports multiple processors; when the network card connected to the adapter card is an intelligent network card that supports multiple processors, one end of the first signal line is set to ground, and the first level signal is a low level signal; when the network card connected to the adapter card is an intelligent network card that supports multiple processors, one end of the second signal line is set to be suspended, and the second level signal is a high level signal.

[0060] In some embodiments of the present invention, the network card type includes a non-intelligent network card; when the network card connected to the adapter card is a non-intelligent network card, one end of the first signal line is set to be suspended, and the first level signal is a high level signal; when the network card connected to the adapter card is a non-intelligent network card, one end of the second signal line is set to be suspended, and the second level signal is a high level signal.

[0061] In some embodiments of the present invention, when the network card connected to the adapter card is provided with a second connector, the first connector is connected to the second connector through a first cable; when the network card connected to the adapter card is not provided with a second connector, the first connector is connected to itself through the second cable. For example, when the network card is also provided with an NCSI connector, Figure 2 , Figure 3 , the NCSI connectors are connected through NCSI cables. If the network card is not equipped with an NCSI connector, Figure 4 , the NCSI connector of the motherboard is connected to itself through the DUMMY cable. By setting different cable connections, it can adapt to the situation where there is a connector in different network cards and improve compatibility.

[0062] In actual applications, the network card connection conditions are divided into five types according to the network card type (X8X8 smart network card, X16 smart network card, non-smart network card), the number of network cards, and the presence or absence of NCSI connectors, as shown in Table 2:

[0063]

[0064] Table 2

[0065] Configuration 1: For an X16 smart NIC (with NCSI connector), the PRESENCE_N pin (signal line) is grounded as a low-level signal, the SEC_NIC_PRSNT_N pin is floating as a high-level signal, and the NIC_BW_ID pin is floating as a high-level signal, and the NCSI connectors are connected through an NCSI cable.

[0066] Configuration 2 (such as Figure 2): For two X16 smart NICs (with NCSI connectors), the PRESENCE_N pin (signal line) is grounded as a low-level signal, the SEC_NIC_PRSNT_N pin is grounded as a low-level signal, the NIC_BW_ID pin is left floating as a high-level signal, and connected between the NCSI connectors through an NCSI cable.

[0067] Configuration 3 (such as Figure 3 ): For 1 X8X8 smart network card (with NCSI connector), the pin (signal line) where PRESENCE_N is located is grounded as a low-level signal, the pin where SEC_NIC_PRSNT_N is located is suspended as a high-level signal, and the pin where NIC_BW_ID is located is grounded as a low-level signal, and connected between the NCSI connectors through the NCSI cable.

[0068] Configuration 4 (such as Figure 4 ): For one X16 smart NIC (without NCSI connector), the PRESENCE_N pin (signal line) is grounded as a low-level signal, the SEC_NIC_PRSNT_N pin is suspended as a high-level signal, and the NIC_BW_ID pin is suspended as a high-level signal, and is connected to itself at the NCSI connector through a DUMMY cable.

[0069] Configuration 5: For one X8X8 smart NIC (without NCSI connector), the PRESENCE_N pin (signal line) is grounded as a low-level signal, the SEC_NIC_PRSNT_N pin is left floating as a high-level signal, the NIC_BW_ID pin is grounded as a low-level signal, and is connected to itself at the NCSI connector through a DUMMY cable.

[0070] Configuration 6: Non-intelligent NIC.

[0071] Step 103: According to the type of the network card, control the server to execute configuration of adapting the network card connected to the adapter card.

[0072] In some embodiments of the present invention, the mainboard is provided with an expansion processor, such as Figure 2 , Figure 3 , Figure 4 PCA9555 in the MB board controls the server to execute the configuration adapted for the network card connected to the adapter card according to the network card type, including: transmitting the network card type to the core processor through the extension processor; in response to the control of the core processor, controlling the server to execute the bandwidth allocation mode adapted for the network card connected to the adapter card according to the network card type.

[0073] In some embodiments of the present invention, controlling the server to execute a bandwidth allocation mode adapted for the network card connected to the adapter card according to the network card type includes: controlling the server to execute a first bandwidth allocation mode when the network card connected to the adapter card is a smart network card that supports a single processor; and controlling the server to execute a second bandwidth allocation mode when the network card connected to the adapter card is a smart network card that supports multiple processors.

[0074] The first bandwidth allocation mode is a bandwidth allocation mode supporting a single processor; and the second bandwidth allocation mode is a bandwidth allocation mode supporting multiple processors.

[0075] In some instances, a bandwidth allocation mode for a single processor is supported, i.e., bandwidth allocation that is compatible with the smart network card X16 of the Signle-host, and a bandwidth allocation mode for multiple processors is supported, i.e., bandwidth allocation that is compatible with the smart network card X8X8 of the Mignle-host.

[0076] In some embodiments of the present invention, the mainboard is provided with a first logic controller, such as Figure 2 , Figure 3 , Figure 4 The CPLD (Complex Programmable Logic Device) in the MB board controls the server to execute the configuration adapted for the network card connected to the adapter card according to the network card type, including: controlling the server to execute the clock output mode adapted for the network card connected to the adapter card according to the network card type through the first logic controller.

[0077] In some embodiments of the present invention, the server is controlled to execute a clock output mode adapted to the network card connected to the adapter card according to the type of the network card, including: when the network card connected to the adapter card is a smart network card, the server is controlled to execute the first clock output mode or the second clock output mode; when the network card connected to the adapter card is a non-smart network card, the server is controlled to execute the second clock output mode.

[0078] The first clock output mode is a mode in which the clock is output without pressing the power button, and the second clock output mode is a mode in which the clock is output after pressing the power button.

[0079] In some examples, the mode of outputting the clock without pressing the power button is to output the clock in S5, and the mode of outputting the clock after pressing the power button is to output the clock in S0.

[0080] Among them, S0 means that the computer will start only after pressing the power button, and S5 means that the computer can start without pressing the power button.

[0081] In some embodiments of the present invention, the server is provided with a switch board (SwitchBoard) connected to the main board, and the switch board is provided with a second logic controller, such as Figure 2 , Figure 3 , Figure 4 The CPLD in the Switch board controls the server to execute the configuration adapted for the network card connected to the adapter card according to the network card type, including: through the second logic controller, controlling the server to execute the power supply mode adapted for the network card connected to the adapter card according to the network card type.

[0082] In some embodiments of the present invention, controlling the server to execute a power supply mode adapted to the network card connected to the adapter card according to the type of the network card includes: when the network card connected to the adapter card is a smart network card, controlling the server to execute a first power supply mode; when the network card connected to the adapter card is a non-smart network card, controlling the server to execute a second power supply mode.

[0083] The first power supply mode is a mode in which power is supplied without pressing a power button, and the second power supply mode is a mode in which power is supplied after pressing a power button.

[0084] In some examples, the mode in which power is supplied without pressing the power button is power supplied in S5, and the mode in which power is supplied after pressing the power button is power supplied in S0.

[0085] In some embodiments of the present invention, the server is provided with a fan board (FANBoard) connected to the mainboard, and the fan board is provided with a third logic controller, such as Figure 2 , Figure 3 , Figure 4 The CPLD in the FAN board controls the server to execute the configuration adapted for the network card connected to the adapter card according to the network card type, including: through the third logic controller, controlling the server to execute the heat dissipation mode adapted for the network card connected to the adapter card according to the network card type.

[0086] In some embodiments of the present invention, the server is controlled to execute a cooling mode adapted to the network card connected to the adapter card according to the type of the network card, including: when the network card connected to the adapter card is a smart network card, the server is controlled to execute a first cooling mode; when the network card connected to the adapter card is a non-smart network card, the server is controlled to execute a second cooling mode.

[0087] The first heat dissipation mode is a mode in which heat is dissipated without pressing a power button, and the second heat dissipation mode is a mode in which heat is dissipated only after pressing a power button.

[0088] In some examples, the mode in which heat is dissipated without pressing the power button is heat dissipated in S5, and the mode in which heat is dissipated after pressing the power button is heat dissipated in S0.

[0089] In the hardware adaptation of the smart network card, we need to pay attention to the following aspects:

[0090] In-place identification: used to let the server management system know how many smart network cards are currently available, so as to perform asset management and related configuration.

[0091] Power supply: Unlike ordinary network cards that use S0 power supply, smart network cards need to use S5 power supply.

[0092] Clock: Generally, the clock is provided by S0. A small number of manufacturers require 100M clock to be provided by S5.

[0093] Heat dissipation: The Smart NIC consumes a lot of power and the power supply is completed in the S5 state. Therefore, in terms of heat dissipation logic, the system needs to recognize that the Smart NIC is in place and start the fan in S5 to provide heat dissipation.

[0094] Among them, S0 means that the computer will start only after pressing the power button, and S5 means that the computer can start without pressing the power button.

[0095] For the configurations in Table 2 above, the server uses the adapted configurations shown in Table 3 below:

[0096]

[0097] Table 3

[0098] Configuration 1: For one X16 smart NIC (with NCSI connector), one power supply uses S5, the other power supply uses S0, and the fan uses S5 for cooling.

[0099] Configuration 2: For 2 x16 smart NICs (with NCSI connectors), one power supply uses S5 and the other power supply uses S5, and the fan uses S5 for cooling.

[0100] Configuration 3: For 1 X8X8 smart NIC (with NCSI connector), one power supply is powered by S5, the other power supply is powered by S0, and the fan uses S5 for cooling.

[0101] Configuration 4: For one X16 smart NIC (without NCSI connector), one power supply uses S5, the other power supply uses S0, and the fan uses S5 for heat dissipation.

[0102] Configuration 5: For one X8X8 smart NIC (without NCSI connector), one power supply uses S5, the other power supply uses S0, and the fan uses S5 for heat dissipation.

[0103] Configuration 6: Non-intelligent network card, one power supply uses S0 for power supply, the other power supply uses S0 for power supply, and the fan uses S0 for heat dissipation.

[0104] The following combination Figure 2 , Figure 3 , Figure 4 , the above configurations are exemplified as follows:

[0105] For configuration 2:

[0106] like Figure 2 , the system needs to support 2 X16 smart NICs (with NCSI connectors on the card end). The MB-side NCSI connector PRESENCE_N, SEC_NIC_PRSNT_N, and NIC_BW_ID signals are pulled up to P3V3_STBY (standby power) by default, and then connected to the MB CPLD and PCA9555.

[0107] After receiving these three signals, the MB CPLD can distinguish the current smart network card type according to the truth table shown in Table 2, and then control the 100M clock to output in S5 or S0.

[0108] After PCA9555 receives these three signals, the CPU can read them through I2C, and then distinguish the current smart network card type according to the truth table shown in Table 2, and then control the bandwidth allocation to X8X8 or X16.

[0109] At this time, the level received by MB CPLD and PCA9555 is: 001, which means that Smart NIC 0 is in place, Smart NIC 1 is in place, and the Smart NIC bandwidth is X16 (i.e. single-host).

[0110] In addition, the PRESENCE_N and SEC_NIC_PRSNT_N signals are simultaneously led to the SW board CPLD. After the SW board CPLD learns that the two in-position signals are equal to 00, it controls VR0 and VR1 to power on at S5. In addition, the FAN_S5_EN signal is pulled high to notify the FAN Board CPLD to control the fan to start rotating at S5.

[0111] It must be noted that the PRESENCE_N and SEC_NIC_PRSNT_N signals are looped back to GND on the MB-side cable and do not need to be connected to the Smart NIC. The NIC_BW_ID signal is not used and can be left floating. These three signals on NCSI cable 2 are not actually connected to the peer NIC.

[0112] For configuration 1:

[0113] Similarly, the difference between configuration 1 in Table 2, which supports one X16 smart NIC (with an NCSI connector on the card end), and configuration 2 is that the MB side does not ground the SEC_NIC_PRSNT_N signal, that is, it is left floating and not used. At this time, the level received by the MB CPLD and PCA9555 is: 011, which means that smart NIC 0 is in place, smart NIC 1 is not in place, and the smart NIC bandwidth is X16 (i.e. single-host). After the SW board CPLD learns that the two in-place signals are equal to 01, it controls VR0 to power on in S5 and VR1 to power on in S0. In addition, the FAN_S5_EN signal is pulled high to notify the FAN Board CPLD to control the fan to start in S5.

[0114] For configuration 3:

[0115] like Figure 3 , supports 1 X8X8 smart NIC (with NCSI connector on the card end). On the MB side cable, PRESENCE_N and NIC_BW_ID loopback to GND, and the SEC_NIC_PRSNT_N signal is left floating. At this time, the level received by the MB CPLD and PCA9555 is: 010, and the MB can know that smart NIC 0 is in place, smart NIC 1 is not in place, and the current smart NIC bandwidth is X8X8 (i.e., muti-host). After the SW board CPLD knows that the two in-place signals are equal to 01, it controls VR0 to power on in S5 and VR1 to power on in S0. In addition, the FAN_S5_EN signal is pulled high to notify the FAN Board CPLD to control the fan to start in S5.

[0116] For configuration 4:

[0117] like Figure 4 , supports 1 X16 smart NIC (no NCSI connector on the card end). Since there is no related connector on the smart NIC end, a dummy cable is required on the MB side (only connected to the MB end), with PRESENCE_N loopback to GND on the cable, and SEC_NIC_PRSNT_N and NIC_BW_ID signals left floating. At this time, the level received by the MB CPLD and PCA9555 is: 011, and the MB can know that smart NIC 0 is in place, smart NIC 1 is not in place, and the current smart NIC bandwidth is X16 (i.e. single-host). After the SW board CPLD knows that the two in-place signals are equal to 01, it controls VR0 to power on in S5 and VR1 to power on in S0. In addition, the FAN_S5_EN signal is pulled high to notify the FAN Board CPLD to control the fan to start in S5.

[0118] For configuration 5:

[0119] Supports 1 X8X8 smart network card (no NCSI connector on the card side), refer to configuration 4.

[0120] For configuration 6:

[0121] There are differences between ordinary network cards, whether they support NCSI or not. However, for ordinary network cards, they are all powered by S0 in terms of power supply and clock, and there is no difference in bandwidth between X8X8 and X16, so the system does not need to know whether it is in place or not. As a standard PCIe device, the BIOS / BMC can obtain relevant information according to the normal boot process. Therefore, the PRESENCE_N, SEC_NIC_PRSNT_N, and NIC_BW_ID signals on the MB side in configuration 6 are all suspended, that is, when these three signals are equal to the default state of 111, it is considered that the current configuration is hanging under the ordinary network card, and no special processing is required in the timing. If the ordinary network card supports NCSI, these three signals are all suspended when making NCSI cable 0. If the ordinary network card does not support NCSI, the MB side connector does not need to be connected to anything, and the Dummy cable does not need to be used.

[0122] In an embodiment of the present invention, by acquiring level signals transmitted by multiple signal lines of the first connector in the server mainboard, one end of the multiple signal lines is set to be grounded or suspended according to the network card connection status of the adapter card in the mainboard, and according to the level signals transmitted by the multiple signal lines, it is determined whether the adapter card in the mainboard is connected to the network card and the network card type of the network card connected to the adapter card; according to the network card type, the server is controlled to execute the configuration adapted to the network card connected to the adapter card, thereby realizing the execution of the configuration adapted to the network card in the server according to the network card type, thereby being compatible with smart network cards of multiple manufacturers and improving the compatibility of the server.

[0123] The following combination Figure 5 The present invention is exemplified as follows:

[0124] 1. Build the hardware circuit, the main features are as follows:

[0125] a. The NCSI connector PRESENCE_N, SEC_NIC_PRSNT_N, and NIC_BW_ID signals on the MB side are pulled up to P3V3_STBY by default, and then connected to the MB CPLD and PCA9555.

[0126] b. The PRESENCE_N and SEC_NIC_PRSNT_N signals are simultaneously led to the SW board CPLD, and the SW CPLD leads out the FAN_S5_EN signal and connects it to the FAN Board CPLD.

[0127] c. The P12V / P3V3 VR in the SW board that powers the smart network card must be controlled by the SW CPLD and have the ability to power on and off in S5.

[0128] 2. According to the smart network cards summarized in Table 2, different cables are configured for different smart network cards according to customer needs, and various types of NCSI cables and Dummy cables are manufactured accordingly.

[0129] 3. MB CPLD and SW Board CPLD refer to Table 2 truth table for logic design and development.

[0130] 4. After the system is correctly installed and the AC is powered on, accurate identification and configuration of various types of smart NICs can be completed. For example, after the AC is powered on and enters the S5 state, the MB and SW boards detect the PRESENCE_N, SEC_NIC_PRSNT_N, and NIC_BW_ID signal states, determine the current smart NIC type based on the truth table shown in Table 2, and execute the corresponding bandwidth allocation, power supply, clock, and fan control logic.
