[0002] The present application claims priority to the Chinese patent application No. 202411336472.4, filed on September 24, 2024, and entitled "Server control method based on network card, server, device, medium and product", the content of which is incorporated herein by reference in its entirety.

[0004] With the application of big data, artificial intelligence and other technologies, data has been growing exponentially in recent years, leading to the fact that traditional servers with CPUs (Central Processing Unit) as the core of data processing cannot meet the demand for data processing, and AI (Artificial Intelligence) servers equipped with GPUs (Graphics Processing Unit) have emerged as the times require.

[0005] For AI servers, some leading manufacturers in the AI field have developed AI server architecture specifications according to their own needs, such as the MGX (Modular GPU Acceleration Platform) specification. The specification makes detailed requirements for various physical interface specifications, signal definitions in the server, and does not allow other server manufacturers to modify them.

[0006] When designing AI servers, different customer groups have different usage needs, and different manufacturers' smart network cards need to be compatible in the server. However, currently each internet manufacturer has its own self-developed smart network card model, and each manufacturer has carried out custom design according to its own needs based on the specification, with various shapes, specifications, bus types and signal definitions. There is no complete uniformity. Moreover, specifications such as MGX are defined according to manufacturers' own smart network cards, without considering the actual situation of self-developed smart network cards of other domestic manufacturers, which makes the compatibility of smart network cards face great challenges when designing AI servers based on the MGX specification.

[0030] In order to more clearly illustrate the technical solutions of the present application, the drawings needed to be used in the description of the present application will be briefly introduced as follows. Obviously, the drawings in the following description are only some embodiments of the present application, and all other embodiments obtained by those skilled in the art without creative labor based on these drawings are within the protection scope of the present application.

[0031] In the related art, different Riser cards (adapter cards) are developed to meet the different signal requirements of smart network cards from different manufacturers, and are used one-to-one (Riser card and smart network card). The AI server is a relatively complex system, and it is time-consuming and laborious to replace the board card. Machine reassembly may cause other problems due to improper operation, increasing machine maintenance costs. At the same time, multiple board cards need to be designed to meet the needs of different scenarios, increasing the cost of research and development, production and system maintenance. Moreover, the existing board card also does not meet the requirements of the MGX specification, and the related board card cannot be used in the server.

[0032] In the embodiments of the present application, in view of the problems of numerous smart network card models and complex, cumbersome and time-consuming board card replacement steps, through special hardware architecture design and different cables, the compatible design of smart network cards of different forms from multiple manufacturers can be easily realized on the basis of small changes without time-consuming and laborious operations, thereby avoiding the development of multiple types of Riser board cards, greatly saving the development and maintenance costs of the server, and improving the development and maintenance efficiency. Moreover, since the MGX and other architecture specifications strictly limit the connectors and signal definitions of the mainboard, some embodiments of the present application can realize this function on the existing connectors without violating the MGX and other architecture specifications.

[0033] In the embodiments of the present application, a complete solution is given through hardware architecture design, logic design and cable design, and a truth table with unique identification (as shown in Table 2) is given, which can complete the type identification and in-place judgment of multiple smart network cards. By using the original NCSI (Network Controller Sideband Interface, a network interface protocol) connector signal definition of the 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 problem of smart network cards from various manufacturers under the MGX and other architecture specifications, greatly expanding the configuration diversity of the AI server. Moreover, compared with the traditional method of manufacturing multiple Riser boards, the present application saves time and does not cause other problems due to the cumbersome operation steps such as replacing the board card, greatly improving the maintenance efficiency and reducing the research and development and production costs.

[0034] Specifically, in the hardware architecture design, special processing is required for the three signals at the NCSI connector in the MB (Main Board), and it does not violate the MGX specification definition, and the complete hardware topology architecture between the MB, SW (Switch), and FAN (Fan) boards is given. In logic, a truth table with unique identification is given, and based on this truth table, type identification and in-place judgment of multiple intelligent network cards can be completed. In cable design, based on the identified type of intelligent network card, various specific type cables are given, and the signal processing method in cable design is specified.

[0035] Further illustrated below in conjunction with the drawings:

[0036] Referring to FIG. 1, a step flowchart of a server control method based on a network card is shown, in some examples, the server can be an AI server, such as an AI server based on the MGX specification, the AI server can be equipped with a CPU and a GPU, and the network card can be an intelligent network card. Compared with a non-intelligent network card, the intelligent network card can undertake part of the data processing function, which can include the following steps:

[0037] Step 101, obtaining the level signals transmitted by the plurality of signal lines of the first connector in the server mainboard, one end of the plurality of signal lines is set to ground or suspended according to the network card connection of the riser card in the mainboard.

[0038] In actual application, as shown in FIG. 2, FIG. 3, and FIG. 4, the server is provided with a mainboard (MB), and the network card is connected to the mainboard through a riser card. The mainboard is provided with a first connector, which is an NCSI connector, and the first connector is provided with a plurality of signal lines for transmitting different signals.

[0039] In order to be compatible with different intelligent network cards, detect whether the network card is online, and distinguish different types of network cards, the plurality of signal lines can be grounded or suspended at one end of the first connector, thereby generating different level signals, such as low level signals when grounded and high level signals when suspended. Through the arrangement and combination of the signals generated by the plurality of signal lines, the server can obtain the specific connection of the network card, such as which riser card is connected to the network card and the type of the connected network card.

[0040] In some embodiments, the type of the network card can include a single processor (Single-host) supporting intelligent network card (i.e., X16 intelligent network card, which requires only one CPU to provide PCIe X16 signal), multi-processor (Muti-host) supporting intelligent network card (i.e., X8X8 intelligent network card, which requires two CPUs in the system to provide one way PCIe X8 signal), and non-intelligent network card (i.e., ordinary network card).

[0041] In some embodiments of the application, the level signal transmitted by the plurality of signal lines of the first connector in the server motherboard is acquired, including: acquiring the first level signal transmitted by the first signal line of the first connector in the server motherboard, the first signal line being used for transmitting the level signal of whether the riser card is connected with the network card; and acquiring the second level signal transmitted by the second signal line of the first connector in the server motherboard, the second signal line being used for transmitting the level signal of the network card type of the network card connected with the riser card.

[0042] In actual application, different signal lines in the first connector can transmit different signals, mainly including two types, the first signal line being used for transmitting the level signal of whether the riser card is connected with the network card, i.e. being used for in-place judgment, such as through the PRESENCE_N, SEC_NIC_PRSNT_N signals to perform in-place judgment, and the second signal line being used for transmitting the level signal of the network card type of the network card connected with the riser card, i.e. being used for distinguishing the type of the intelligent network card, such as through the NIC_BW_ID signal to distinguish the type of the intelligent network card.

[0043] In some embodiments of the application, the motherboard is provided with one or more riser cards, and in the case that the motherboard is provided with a plurality of riser cards, the first connector transmits the level signals of whether different riser cards are connected with the network card through different first signal lines. For example, the first connector transmits PRESENCE_N, SEC_NIC_PRSNT_N through the first signal line, PRESENCE_N being used for identifying whether the first riser card is connected with the network card, and SEC_NIC_PRSNT_N being used for identifying whether the second riser card is connected with the network card.

[0044] In actual application, different signal lines can correspond to different pins of the first connector, and be used for transmitting different signals. The MGX specification makes detailed definition for the NCSI connector of the MB end, such as Table 1, including RBT, UART, PRESENCE, PKG_ID signals.

[0045] Table 1

[0046] In actual application, the PRESENCE signal is the intelligent network card in-place signal, and the signal is grounded by default at the intelligent network card end. When the NCSI cable is normally installed, the MB end can learn that there is an intelligent network card in the current system after identifying that the signal is low. This leads to a series of design problems, which limits the configuration implementation of the server, and the details are as follows:

[0047] 1. There is only one NCSI connector at the MB end of the server, but the system configuration requires to support one or two intelligent network cards.

[0048] 2. When configuring with only one smart network card (only one smart network card is inserted in Riser0), Riser1 needs to install a regular network card to maximize the utilization of system resources. However, the power supply and heat dissipation solutions of regular network cards and smart network cards are different.

[0049] 3. Smart network cards are further divided into two types: X8X8 (i.e., smart network cards that support a single processor) and X16 (i.e., smart network cards that support multiple processors), which makes it impossible for the system to accurately know the status of the card.

[0050] In some embodiments of this application, without changing the original definition of MGX and other specifications, a cable-assisted approach is used to fully utilize the PKG_ID 0 / 1 signal to achieve the system design goals.

[0051] According to relevant specifications, the PKG_ID 0 / 1 signal is output from the MB to the smart network interface card (NIC) and is used to configure the NIC's ID. It's important to note that the PKG_ID 0 / 1 signal is not a changing signal; its state is either constantly high or constantly low, and other manufacturers' smart NICs do not require this signal.

[0052] Therefore, in the cable design, the MB end of this PKG_ID 0 / 1 signal is looped back to GND (i.e., grounded) or left floating, and used 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. It is looped back to GND at the smart NIC connector, which can realize the relevant functions defined by the smart NIC, and at the same time meet the requirements of the MB end for the identification and differentiation of multiple types of smart NICs.

[0053] In other words, in the original definitions 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 terminal of this PKG_ID 0 / 1 signal to GND (i.e., 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.

[0054] With the above settings, one end of the signal line can be set to ground or floating depending on the network card connection status of the adapter card in the motherboard. This enables the determination of the presence of at least two network cards and the ability to distinguish the network card type of the present network card, thereby improving the server's compatibility with smart network cards.

[0055] Step 102, according to the level signal transmitted by the plurality of signal lines, determine whether the adapter card is connected to the network card in the mainboard and the network card type of the network card connected by the adapter card.

[0056] In some embodiments of the present application, according to the level signal transmitted by the plurality of signal lines, determine whether the adapter card is connected to the network card in the mainboard and the network card type of the network card connected by the adapter card, comprising:

[0057] According to the first level signal, determine whether the adapter card is connected to the network card in the mainboard; according to the second level signal, determine the network card type of the network card connected by the adapter card.

[0058] In some embodiments of the present application, 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.

[0059] In some embodiments of the present application, the network card type includes a smart network card supporting a single processor; in the case that the network card connected by the adapter card is a smart network card supporting a single processor, one end of the first signal line is set to ground, and the first level signal is a low level signal; in the case that the network card connected by the adapter card is a smart network card supporting a single processor, one end of the second signal line is set to ground, and the second level signal is a low level signal.

[0060] In some embodiments of the present application, the network card type includes a smart network card supporting multiple processors; in the case that the network card connected by the adapter card is a smart network card supporting multiple processors, one end of the first signal line is set to ground, and the first level signal is a low level signal; in the case that the network card connected by the adapter card is a smart network card supporting multiple processors, 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 application, the network card type includes a non-smart network card; in the case that the network card connected by the adapter card is a non-smart network card, one end of the first signal line is set to be suspended, and the first level signal is a high level signal; in the case that the network card connected by the adapter card is a non-smart network card, one end of the second signal line is set to be suspended, and the second level signal is a high level signal.

[0062] In some embodiments of the present application, when the network card connected by the adapter card is provided with a second connector, the first connector is connected with the second connector through a first cable; when the network card connected by the adapter card is not provided with a second connector, the first connector is connected with itself through a second cable. For example, when the network card is also provided with an NCSI connector, the NCSI connectors are connected through an NCSI cable, as shown in FIG. 2 and FIG. 3; when the network card is not provided with an NCSI connector, the NCSI connector of the mainboard is connected with itself through a DUMMY cable, as shown in FIG. 4. By setting different cable connections, it can further adapt to the case of having or not having a connector in different network cards, and improve compatibility.

[0063] In actual application, according to the type of network card (X8X8 smart network card, X16 smart network card, non-smart network card), the number of network cards, and whether the NCSI connector is provided, the connection of the network card is classified into 5 types, as shown in Table 2.

[0064] Table 2

[0065] Configuration 1: for 1 X16 smart network card (with 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, and the NIC_BW_ID pin is left floating as a high-level signal, and the NCSI connectors are connected through an NCSI cable.

[0070] Configuration 6: non-smart NIC.

[0071] Step 103: according to the type of the network card, the server is controlled to perform a configuration suitable for the network card connected to the adapter card.

[0072] In some embodiments of the present application, the mainboard is provided with an expansion processor, such as the PCA9555 in the MB board in FIGS. 2, 3, and 4, and according to the type of the network card, the server is controlled to perform a configuration suitable for the network card connected to the adapter card, including: transmitting the type of the network card to the core processor through the expansion processor; and in response to the control of the core processor, according to the type of the network card, the server is controlled to perform a bandwidth allocation mode suitable for the network card connected to the adapter card.

[0073] In some embodiments of the present application, according to the type of the network card, the server is controlled to perform a bandwidth allocation mode suitable for the network card connected to the adapter card, including: in the case where the network card connected to the adapter card is a smart NIC supporting a single processor, the server is controlled to perform a first bandwidth allocation mode; and in the case where the network card connected to the adapter card is a smart NIC supporting multiple processors, the server is controlled to perform a second bandwidth allocation mode.

[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 examples, the bandwidth allocation mode supporting a single processor is a bandwidth allocation mode suitable for a Signle-host smart NIC X16, and the bandwidth allocation mode supporting multiple processors is a bandwidth allocation mode suitable for a Mignle-host smart NIC X8 X8.

[0076] In some embodiments of the present application, the mainboard is provided with a first logic controller, such as the CPLD (Complex Programmable Logic Device) in the MB board in FIGS. 2, 3, and 4, and according to the type of the network card, the server is controlled to perform a configuration suitable for the network card connected to the adapter card, including: through the first logic controller, according to the type of the network card, the server is controlled to perform a clock output mode suitable for the network card connected to the adapter card.

[0077] In some embodiments of the present application, the server is configured to control the server to perform a clock output mode adapted to the network card connected to the adapter card according to the type of the network card, including: in the case that the network card connected to the adapter card is a smart network card, the server is controlled to perform a first clock output mode or a second clock output mode, and in the case that the network card connected to the adapter card is a non-smart network card, the server is controlled to perform the second clock output mode.

[0078] The first clock output mode is a mode of outputting clock without pressing the power-on key, and the second clock output mode is a mode of outputting clock after pressing the power-on key.

[0079] In some embodiments, the mode of outputting clock without pressing the power-on key is outputting clock in S5, and the mode of outputting clock after pressing the power-on key is outputting clock in S0.

[0080] The S0 is starting after pressing the power-on key, and the S5 is starting without pressing the power-on key.

[0081] In some embodiments of the present application, the server is provided with a switch board connected to the mainboard, and the switch board is provided with a second logic controller, such as the CPLD in the switch board of FIGS. 2, 3 and 4. The server is controlled to perform a configuration adapted to the network card connected to the adapter card according to the type of the network card, including: through the second logic controller, the server is controlled to perform a power supply mode adapted to the network card connected to the adapter card according to the type of the network card.

[0082] In some embodiments of the present application, the server is controlled to perform a power supply mode adapted to the network card connected to the adapter card according to the type of the network card, including: in the case that the network card connected to the adapter card is a smart network card, the server is controlled to perform a first power supply mode; and in the case that the network card connected to the adapter card is a non-smart network card, the server is controlled to perform a second power supply mode.

[0083] The first power supply mode is a mode of supplying power without pressing the power-on key, and the second power supply mode is a mode of supplying power after pressing the power-on key.

[0084] In some examples, the mode of supplying power without pressing the power-on key is supplying power in S5, and the mode of supplying power after pressing the power-on key is supplying power in S0.

[0085] In some embodiments of the present application, the server is provided with a fan board connected to the mainboard, and the fan board is provided with a third logic controller, such as the CPLD in the fan board of FIGS. 2, 3 and 4. The server is controlled to perform a configuration adapted to the network card connected to the adapter card according to the type of the network card, including: through the third logic controller, the server is controlled to perform a heat dissipation mode adapted to the network card connected to the adapter card according to the type of the network card.

[0086] In some embodiments of the present application, according to the type of the network card, the control server executes a heat dissipation mode adapted to the network card connected to the adapter card, including: in the case that the network card connected to the adapter card is an intelligent network card, the control server executes a first heat dissipation mode; in the case that the network card connected to the adapter card is a non-intelligent network card, the control server executes a second heat dissipation mode.

[0087] The first heat dissipation mode is a mode of heat dissipation without pressing the power-on key, and the second heat dissipation mode is a mode of heat dissipation after pressing the power-on key.

[0088] In some embodiments, the mode of heat dissipation without pressing the power-on key is heat dissipation under S5, and the mode of heat dissipation after pressing the power-on key is heat dissipation under S0.

[0089] In the hardware adaptation of the intelligent network card, the following aspects need to be concerned:

[0090] Bit recognition: used to let the server management system know that there are several intelligent network cards currently, and then do asset management and make relevant configuration.

[0091] Power supply: different from the S0 power supply of ordinary network cards, the intelligent network card needs to complete the power supply under S5.

[0092] Clock: generally provides clock under S0. A small number of manufacturers require 100M clock under S5.

[0093] Heat dissipation: the intelligent network card has large power consumption and the S5 state is completed, so in the heat dissipation logic, the system needs to recognize the intelligent network card in place, and then start the cooling fan under S5 to provide heat dissipation.

[0094] The S0 is started after pressing the power-on key, and the S5 is started without pressing the power-on key.

[0095] For the several configurations of Table 2 above, the server adopts the adapted configurations as shown in Table 3 below:

[0096] Table 3

[0097] Configuration 1: for one X16 intelligent network card (with NCSI connector), one power supply is powered under S5, another power supply is powered under S0, and the fan is cooled under S5.

[0098] Configuration 2: for two X16 intelligent network cards (with NCSI connector), one power supply is powered under S5, another power supply is powered under S5, and the fan is cooled under S5.

[0099] Configuration 3: for one X8X8 intelligent network card (with NCSI connector), one power supply is powered under S5, another power supply is powered under S0, and the fan is cooled under S5.

[0100] Configuration 4: for 1 X16 smart NIC (without NCSI connector), one power supply is powered under S5, another power supply is powered under S0, and the fan is cooled under S5.

[0101] Configuration 5: for 1 X8X8 smart NIC (without NCSI connector), one power supply is powered under S5, another power supply is powered under S0, and the fan is cooled under S5.

[0102] Configuration 6: non-smart NIC, one power supply is powered under S0, another power supply is powered under S0, and the fan is cooled under S0.

[0103] The following is an exemplary description of the above configurations in combination with FIG. 2, FIG. 3, and FIG. 4:

[0104] For configuration 2:

[0105] As shown in FIG. 2, two X16 smart NICs (card end with NCSI connector) need to be supported in the system. The MB NCSI connector PRESENCE_N, SEC_NIC_PRSNT_N, and NIC_BW_ID signals are pulled up to P3V3_STBY (standby power supply) by default, and then connected to the MB CPLD and PCA9555.

[0106] After receiving the three signals, the MB CPLD can distinguish the current smart NIC type according to the truth table shown in Table 2, and then control the 100M clock to be output under S5 or S0.

[0107] After receiving the three signals, the CPU can read through I2C, and then distinguish the current smart NIC type according to the truth table shown in Table 2, and then control the bandwidth allocation to be X8X8 or X16.

[0108] At this time, the levels received by the MB CPLD and PCA9555 are: 001, representing that smart NIC 0 is in place, smart NIC 1 is in place, and the smart NIC bandwidth is X16 (i.e. single-host).

[0109] In addition, the PRESENCE_N and SEC_NIC_PRSNT_N signals are simultaneously connected to the SW board CPLD. After the SW board CPLD learns that the two in-place signals are equal to 00, it controls VR0 and VR1 to be powered on under S5. In addition, the FAN_S5_EN signal is pulled high to notify the FAN Board CPLD to control the fan to start under S5.

[0110] It must be pointed out that the PRESENCE_N, SEC_NIC_PRSNT_N signals are loopback to GND on the MB side cable, and do not need to be connected to the smart NIC end. The NIC_BW_ID signal is not used and can be left floating. The 3 signals on the NCSI cable 2 are not actually connected to the opposite end NIC.

[0111] For configuration 1:

[0112] Similarly, the support of 1 X16 smart NIC (card end with NCSI connector) in Table 2 configuration 1, the difference with configuration 2 is that the MB side does not ground the SEC_NIC_PRSNT_N signal, that is, it is left floating. At this time, the MB CPLD, PCA9555 receives the level: 011, which represents that the smart NIC 0 is in place, the 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 be powered on at S5, VR1 to be powered on at S0. In addition, the FAN_S5_EN signal is pulled high to inform the FAN Board CPLD to control the fan to start rotating at S5.

[0113] For configuration 3:

[0114] As shown in FIG. 3, 1 X8X8 smart NIC (card end with NCSI connector) is supported. On the MB side cable, PRESENCE_N, NIC_BW_ID loopback to GND, SEC_NIC_PRSNT_N signal is left floating. At this time, the MB CPLD, PCA9555 receives the level: 010, and the MB can learn that the smart NIC 0 is in place, the smart NIC 1 is not in place, and the current smart NIC bandwidth is X8X8 (i.e. muti-host). After the SW board CPLD learns that the two in-place signals are equal to 01, it controls VR0 to be powered on at S5, VR1 to be powered on at S0. In addition, the FAN_S5_EN signal is pulled high to inform the FAN Board CPLD to control the fan to start rotating at S5.

[0115] For configuration 4:

[0116] As shown in FIG. 4, one X16 smart NIC (no NCSI connector at the card end) is supported. Since there is no related connector at the smart NIC end, a Dummy cable (connected to the MB end only) is used on the MB side, and the PRESENCE_N loopback is connected to GND, and the SEC_NIC_PRSNT_N and NIC_BW_ID signals are left floating. At this time, the levels received by the MB CPLD and PCA9555 are 011, and the MB can know that the smart NIC 0 is in place, the 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, VR0 is powered on at S5, and VR1 is powered on at S0. In addition, the FAN_S5_EN signal is pulled high to notify the FAN Board CPLD to control the fan to start at S5.

[0117] For configuration 5:

[0118] One X8X8 smart NIC (no NCSI connector at the card end) is supported, and reference is made to configuration 4.

[0119] For configuration 6:

[0120] Ordinary NICs also have a difference between supporting NCSI and not supporting NCSI. However, for ordinary NICs, they are all powered by S0 in power supply and clock, and there is no bandwidth difference between X8X8 and X16, so the system does not need to know whether they are in place or not. As a standard PCIe device, the relevant information is obtained by BIOS / BMC 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 left floating, that is, when the three signals are in the default state of 111, it is considered that the ordinary NIC is hung under the current configuration, and at this time, no special treatment is required in timing. If the ordinary NIC supports NCSI, the three signals are all left floating when the NCSI cable 0 is made. If the ordinary NIC 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.

[0121] In some embodiments of the present application, by acquiring the level signals transmitted by a plurality of signal lines of a first connector in a server mainboard, one end of the plurality of signal lines is set to be grounded or floating according to the NIC connection condition of an adapter card in the mainboard, and according to the level signals transmitted by the plurality of signal lines, it is determined whether the adapter card in the mainboard is connected to a NIC and the NIC type of the adapter card connected to the NIC; according to the NIC type, the server is controlled to execute a configuration adapted to the NIC, which realizes executing a configuration adapted to the NIC in the server according to the NIC type, and further compatible with NICs of multiple manufacturers, thereby improving the compatibility of the server.

[0122] The present application is exemplarily described below in combination with Fig. 5:

[0123] 1. Constructing a hardware circuit, the main features are as follows:

[0124] a. The MB end NCSI connector PRESENCE_N, SEC_NIC_PRSNT_N, NIC_BW_ID signal is pulled up to P3V3_STBY by default, and then connected to the MB CPLD and PCA9555.

[0125] b. The PRESENCE_N and SEC_NIC_PRSNT_N signals are simultaneously connected to the SW board CPLD, and the SW CPLD outputs the FAN_S5_EN signal connected to the FAN Board CPLD.

[0126] c. The P12V / P3V3 VR in the SW board for powering the intelligent network card needs to be controlled by the SW CPLD, and has S5 power-on capability.

[0127] 2. According to the intelligent network card summarized in Table 2, different cables are configured according to different customer requirements of the intelligent network card, and corresponding NCSI cables and Dummy cables are made.

[0128] 3. The MB CPLD and SW Board CPLD are logically designed and developed according to the truth table in Table 2.

[0129] 4. After the system is correctly installed and AC powered, accurate identification and configuration of various intelligent network cards can be completed. For example, after AC power-on, enter S5 state, the MB and SW board detect the PRESENCE_N, SEC_NIC_PRSNT_N, NIC_BW_ID signal state, judge the current intelligent network card type based on the truth table shown in Table 2, and execute the corresponding bandwidth allocation, power supply, clock, and fan control logic.
