As shown in fig. 1, the data selector 103 may be a two-out selector, which is used to connect the first storage medium 101 to a different device. The data selector 103 connects the first storage medium 101 with the PCIe gold finger 102 of the intelligent network card by default when power is applied, so that after the PCIe gold finger 102 of the intelligent network card is inserted into the PCIe slot of the server, the intelligent network card is powered on, at this time, the baseboard management controller of the intelligent network card is not powered on yet, but the host end of the server can directly read information in the first storage medium 101 through the PCIe gold finger 102.

Various embodiments corresponding to the intelligent network card are described in detail above, and on the basis of the embodiments, the application also discloses an identification method of the intelligent network card corresponding to the intelligent network card.
Fig. 2 is a flowchart of an identification method of an intelligent network card according to an embodiment of the present application.
As shown in fig. 2, the method for identifying an intelligent network card provided in the embodiment of the present application includes:
s201: after power-on, when a command for inquiring the device state sent by the basic input/output system is received, reading PCIe devices accessed on PCIe slots.
S202: if the identification information can be read, the identification information is compared with the pre-stored intelligent network card identification information.
S203: if the comparison is consistent, determining that the PCIe device is an intelligent network card.
The first storage medium of the intelligent network card stores a unique identifier of the intelligent network card, and is connected with a PCIe golden finger of the intelligent network card through an I2C bus.
In specific implementation, a first storage medium connected with a PCIe golden finger of the intelligent network card through an I2C bus is additionally arranged on a board card of the intelligent network card, and a unique identifier of the intelligent network card is stored in the first storage medium so that equipment connected with the PCIe golden finger can be directly read through the PCIe golden finger and the I2C bus. The method comprises the steps that intelligent network card identification information and consistency judging logic are stored in advance in a host end of a server, identification information read from PCIe equipment connected with PCIe slots is compared with prestored intelligent network card identification information, if the identification information is consistent with the prestored intelligent network card identification information, the PCIe equipment is confirmed to be an intelligent network card, and accordingly corresponding configuration files are called to conduct connection configuration of the host end and the intelligent network card.
The first storage medium may employ charged erasable programmable read-only memory (Electrically Erasable Programmable read only memory, EEPROM) to replace the unique identifier stored therein when needed.
The unique identifier is used for uniquely determining the intelligent network card, so that the baseboard management controller of the server host accurately identifies the intelligent network card and avoids misjudging other PCIe devices as the intelligent network card. The unique identifier may be generated according to production information of the intelligent network card, and may include a serial number, a product name, and the like without sensitive information of the intelligent network card.
In practical application, after the host is powered on, the baseboard management controller at the host obtains the control right of the PCIe gold finger I2C line, and at this time, the intelligent network card is not powered on yet. The basic input/output system at the host end is blocked after being started, and a query device status command (IPMI oem) is sent to the baseboard management controller at the host end in a circulating way. And the substrate management controller at the host computer end reads the identification information of the PCIe device at the PCIe slot position, if the identification information can be read and analyzed into the intelligent network card, the flag bit is set, and a query device state command sent to the basic input/output system returns the correct intelligent network card device type. And the basic input/output system performs initialization setting related to the intelligent network card, and then continues the starting-up flow.
If the baseboard management controller at the host detects that the PCIe slot is connected with the device but cannot read the identification information or cannot parse the identification information into the intelligent network card identification information, the state command of the query device sent by the basic input/output system cannot return a correct result all the time, and after reaching a timeout time (for example, 2 minutes), the basic input/output system considers that the intelligent network card is not currently inserted, and continues to execute a common startup procedure.
According to the identification method of the intelligent network card, the first storage medium connected with the PCIe golden finger of the intelligent network card through the I2C bus is additionally arranged on the board card of the intelligent network card, the unique identification of the intelligent network card is stored in the first storage medium, after the base plate management controller at the host end is electrified, when the inquiry equipment state command sent by the basic input and output system is received, PCIe equipment accessed on the PCIe slot is read, if identification information can be read and is consistent with the prestored intelligent network card identification information, the intelligent network card is identified, corresponding connection configuration is further accurately completed, the misjudgment problem possibly caused by outputting bit data only through the I2C input and output expander in the existing intelligent network card identification scheme is eliminated, normal starting of a server is promoted, and the safety risk of the misjudgment intelligent network card on system service is eliminated.
On the basis of the embodiment, in order to improve the accuracy of identifying the intelligent network card, the intelligent network card identification information specifically comprises a unique identification and bit data output by the I2C input/output expander of the intelligent network card after power on.
Accordingly, step S203: if the comparison is consistent, determining that the PCIe device is an intelligent network card, specifically:
if the identification information comprises a unique identification corresponding to the intelligent network card and bit data corresponding to the intelligent network card, the PCIe device is the intelligent network card.
The I2C input/output expander is connected with the PCIe golden finger through an I2C bus.
In a specific implementation, the intelligent network card identification information stored in the baseboard management controller at the host end may include a board ID of the intelligent network card (i.e. bit data corresponding to the external resistor configuration of the I2C input/output expander) and FRU key information (e.g. product name). The baseboard management controller at the host end compares whether the card ID is correct or not, and then analyzes the product name field from FRU data. If the unique identification and the bit data are consistent with the record of the prestored intelligent network card identification information, indicating that the intelligent network card equipment is in place at the moment, and setting the self-marking position; if the two data or data parsing errors cannot be read from the I2C bus, the flag bits are consistent with an error state.
Based on the above embodiment, in order to update the data in the first storage medium conveniently, in the identification method of the intelligent network card provided in the embodiment of the present application, the intelligent network card further includes a data selector disposed between the first storage medium and a baseboard management controller of the intelligent network card;
the fixed end of the data selector is connected with the first storage medium, the first selection end of the data selector is connected with the PCIe golden finger of the intelligent network card, and the second selection end of the data selector is connected with the baseboard management controller of the intelligent network card;
the data selector defaults to connect the first storage medium with the PCIe golden finger when powered on.
In an implementation, the data selector may be a two-out selector, which is used to connect the first storage medium to a different device. The first storage medium is communicated with the PCIe golden finger of the intelligent network card by default when the data selector is electrified, so that after the PCIe golden finger of the intelligent network card is inserted into the PCIe slot of the server, the intelligent network card is electrified, at the moment, the substrate management controller of the intelligent network card is not electrified yet, but the host end of the server can directly read the information in the first storage medium through the PCIe golden finger.
The second selection end of the data selector is connected with the baseboard management controller of the intelligent network card, so that after the second selection end is communicated with the fixed end, the (I2C 2 interface of the) baseboard management controller of the intelligent network card is connected with the first storage medium, and the baseboard management controller of the intelligent network card can manage the first storage medium.
The control end of the data selector may be externally connected, for example, by switching the internal connection channel under the control of the dial switch, or may be connected to a baseboard management controller (not shown in fig. 1) of the intelligent network card, so as to switch the internal connection channel under the control of the baseboard management controller.
On the basis, the data selector is communicated with the substrate management controller of the intelligent network card and the first storage medium under the control of the substrate management controller of the intelligent network card.
On the basis of the above embodiment, the method for identifying an intelligent network card provided in the embodiment of the present application further includes:
after the baseboard management controller of the intelligent network card controls the data selector to communicate the baseboard management controller of the intelligent network card with the first storage medium and update the unique identifier, the intelligent network card identification information is updated.
In a specific implementation, after the basic input/output system of the host end completes the startup process, the baseboard management controller of the host end establishes communication connection with the baseboard management controller of the intelligent network card. After updating the unique identifier in the first storage medium, the baseboard management controller of the intelligent network card sends a unique identifier updating notification to the baseboard management controller of the host, and the baseboard management controller of the host updates the identifier information of the intelligent network card accordingly.
