Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of data communication, and in particular to a PXE starting and installing method, device and equipment of an intelligent network card and a storage medium. BACKGROUND

[0002] With the gradually widening gap between the growth rate of CPU computing power and the growth rate of data center network transmission rate, CPU computing power encounters a bottleneck, and in the prior art, the CPU is usually flexibly unloaded from the processing tasks that are not suitable for the CPU, so as to meet the data plane network processing requirements and be compatible with the existing network protocol ecology. The core role of this method is to reduce the burden of CPU computing power and let it handle more important tasks. The traditional network card is only responsible for the transmission of the data link, the network stack algorithm and the protocol, and other functions such as storage, network encryption and decryption and security will occupy a large amount of CPU resources.

[0003] The intelligent network card has an operating system, and some intelligent network cards have embedded systems when they are shipped, and do not need to be started and installed with an operating system through the PXE (Preboot Execution Environment) function. However, at present, users of intelligent network cards often purchase intelligent network cards without embedded systems, and install independently developed intelligent network card systems suitable for their own businesses into the intelligent network cards. When the intelligent network card is automatically deployed through the traditional PXE function, the intelligent network card and the PXE server network need to be interconnected to complete the deployment. However, in a real network environment, the intelligent network card and the PXE server may need to cross multiple intermediate network devices such as switches to realize interconnection.

[0004] In a data center cloud management environment, to complete the PXE starting and installing of the intelligent network card, it may be impossible to directly connect to the intermediate network device for configuration, and manual connection and login to the intermediate device are required for operation. If multiple network devices are involved, it will take a lot of time to pass through the network, which is time-consuming and labor-consuming. Moreover, the result of the PXE starting and installing of the intelligent network card cannot be intuitively perceived, and it can only be confirmed whether the installation is successful by restarting the intelligent network card and paying attention to whether the starting is successful.

[0057] Embodiment 1

[0058] As Figure 1 shown, a flow chart of a smart NIC PXE boot installation method in an embodiment of the present application, the smart NIC PXE boot installation method provided by the embodiment of the present application is applied to a smart NIC, as Figure 5 shown, the smart NIC establishes a network communication connection with a PCIe (Peripheral Component Interconnect express, Peripheral Component Interconnect bus) port of a bare metal server, the bare metal server connects a cloud management platform through an IPMI interface, the cloud management platform establishes a communication connection with a PXE server, the PCIe channel is bridged with the IPMI interface, and the method comprises the following steps:

[0059] In step S110, after the smart NIC is powered on by the bare metal server, it is determined whether the physical port of the smart NIC connected to the external network is opened.

[0060] Specifically, the smart NIC is mounted on a bare metal server, and is not connected to an external network port. The bare metal server is powered on and can be connected to a cloud management platform through its IPMI interface. The bare metal server starts from its operating system and runs a preset driver to load a PF (Physical Function, physical function) device provided by the smart NIC for the bare metal server. In the bare metal server, the IPMI interface is connected to the PCIe channel of the bare metal server, and the connection mode can be bridging, which is not limited by the embodiment of the present application.

[0061] The intelligent network card is connected through the IPMI interface of the bare metal server on the cloud management platform, and the intelligent network card is enabled to enter the PXE starting state through the IPMI interface of the bare metal server, and after the intelligent network card enters the PXE starting installation process, it is judged whether the physical port of the intelligent network card connected to the external network is opened. If the state of the physical port of the intelligent network card connected to the external network is opened, it is considered that the intelligent network card can be started and installed through the physical port connected to the external network, and at this time, the standard PXE starting installation process can be entered.

[0062] The implementation of the present application only requires that the server supports the IPMI interface of the bare metal server, and the existing general server supports and is mature in technology, thereby improving the use rate of the method of the present application.

[0063] In step S120, if the physical port is not opened, a DHCP Discovery packet is sent to the IPMI interface of the bare metal server through the network communication connection, an IP address allocated from the PXE server received by the IPMI interface is acquired through the network communication connection, and a communication connection with the PXE server is established according to the IP address.

[0064] Specifically, if the physical port of the intelligent network card connected to the external network is closed, it is considered that the intelligent network card cannot be started and installed through the port connected to the external network, and it is considered that the process of starting and installing through the network communication connection needs to be performed.

[0065] The intelligent network card enters the process of starting and installing through the network communication connection, initializes the PCIe channel of the intelligent network card, so that the intelligent network card can communicate with the bare metal server through the network communication connection, and at this time, the intelligent network card formally enters the process of starting and installing.

[0066] Firstly, the intelligent network card needs to send a DHCP Discovery packet to acquire an IP address for communicating with the PXE server, and the DHCP Discovery packet is sent to the IPMI interface of the bare metal server through the network communication connection. In this embodiment, if the destination MAC address of the DHCP Discovery packet is all f, it indicates that it is a broadcast data packet.

[0067] After the IPMI interface of the bare metal server receives the DHCP Discovery packet, the DHCP Discovery packet is sent to the PXE server through the network communication connection.

[0068] Further, the bare metal server IPMI interface receives the DHCP Offer message returned by the PXE server through the network communication connection, and forwards the DHCP Offer message to the intelligent network card through the network communication connection. The DHCP Offer message includes the IP address allocated to the intelligent network card by the PXE server.

[0069] After the intelligent network card is allocated to the IP address, the intelligent network card sends a DHCP request confirmation message to the IPMI interface of the bare metal server through the network communication connection again, and receives the confirmation message returned by the PXE server through the network communication connection. At this point, the intelligent network card completes the request for allocating the IP address, obtains the IP address allocated by the PXE server, and can further communicate with the PXE server through the address.

[0070] In step S130, the PXE startup installation file request is sent to the IPMI interface through the network communication connection, so that the PXE startup installation file request is sent to the PXE server through the IPMI interface.

[0071] After the intelligent network card receives the confirmation message, the intelligent network card starts sending the PXE startup installation file request to the IPMI interface of the bare metal server through the network communication connection, so that the PXE startup installation file request is sent to the PXE server through the IPMI interface, thereby requesting the PXE startup installation file deployed by the PXE server, and completing the startup and installation of the intelligent network card.

[0072] It can be understood that in the embodiment of the application, the PXE startup installation file includes a binary file, a Grub (GRand Unified Bootloader, multi-operating system startup program) menu, a Kernel and an initd. The specific file content contained in the PXE startup installation file can be determined according to actual conditions, and the embodiment of the application does not limit this.

[0073] In step S140, the PXE startup installation file returned by the PXE server is obtained through the network communication connection, and PXE startup installation is performed through the PXE startup installation file.

[0074] Specifically, the IPMI interface of the bare metal server receives the PXE startup installation file returned by the PXE server through the network communication connection, and forwards the startup installation file to the intelligent network card through the network communication connection.

[0075] The intelligent network card reads the PXE startup installation file, and completes the PXE startup installation of the intelligent network card. The above method improves the efficiency of deploying the intelligent network card and improves the reliability of the PXE startup installation of the intelligent network card.

[0076] Further, after the intelligent network card completes the PXE startup installation through the above steps, the intelligent network card sends the PXE startup installation result to the IPMI interface of the bare metal server again through the network communication connection. After the IPMI interface of the bare metal server receives the PXE startup installation result, the IPMI interface sends the PXE startup installation result to the cloud management platform in the form of capture, so that the administrator confirms whether the PXE startup installation of the intelligent network card is successful according to the PXE startup installation result. The administrator can directly check the result on the cloud management platform, thereby saving the time of configuring intermediate network equipment, improving the efficiency of deploying the intelligent network card, and improving the reliability of the startup and installation of the intelligent network card. Thus, the process of the PXE startup installation of the intelligent network card through the network communication connection and the IPMI interface of the bare metal server ends.

[0077] The PXE startup installation method of the intelligent network card provided by the embodiment of the application is applied to an intelligent network card, the intelligent network card establishes a network communication connection with a PCIe channel of a bare metal server, the bare metal server is connected to a cloud management platform through an IPMI interface, the cloud management platform is connected to a PXE server, the PCIe channel is bridged with the IPMI interface, and the method comprises the following steps: after the intelligent network card is powered on by the bare metal server, it is determined whether a physical port of the intelligent network card connected to an external network is opened; if the physical port is not opened, a DHCP Discovery packet is sent to the IPMI interface of the bare metal server through the network communication connection, an IP address allocated by the PXE server and received by the IPMI interface is acquired through the network communication connection, and a communication connection is established with the PXE server according to the IP address; a PXE startup installation file request is sent to the IPMI interface through the network communication connection, so that the PXE startup installation file request is sent to the PXE server through the IPMI interface; a PXE startup installation file returned by the PXE server and received by the IPMI interface is acquired through the network communication connection, and PXE startup installation is performed through the PXE startup installation file. The intelligent network card communicates with the bare metal server, realizes the startup and installation of the intelligent network card system, saves the time of configuring intermediate network equipment, and improves the efficiency of deploying the intelligent network card.

[0078] Embodiment 2

[0079] As Figure 2As shown, a flowchart of a PXE boot installation method of an intelligent network card in an embodiment of the present application is shown, and the PXE boot installation method of the intelligent network card provided in the embodiment of the present application is applied to a bare metal server, such as Figure 5 As shown, the PCIe channel of the bare metal server establishes a network communication connection with the intelligent network card, the bare metal server connects a cloud management platform through an IPMI interface, the cloud management platform establishes a communication connection with a PXE server, the PCIe channel is bridged with the IPMI interface, and the method comprises the following steps:

[0080] In step S210, the intelligent network card is powered on after receiving the instruction of the cloud management platform.

[0081] Specifically, first, a PXE pre-boot execution environment is built, and a boot installation file of the intelligent network card is deployed in advance, wherein the boot installation file comprises a binary file, a Grub menu, a Kernel and an initd, and the intelligent network card is powered on after receiving the instruction of the cloud management platform.

[0082] It can be understood that in the embodiment of the present application, the PXE boot installation file comprises a binary file, a Grub menu, a Kernel and an initd, and the specific file content contained in the PXE boot installation file can be determined according to actual conditions, and the embodiment of the present application does not limit this.

[0083] In step S220, the DHCP Discovery packet sent by the intelligent network card is received through the network communication connection, the DHCP Discovery packet is sent to the PXE server through the IPMI interface, and the IP address allocated by the PXE server received by the IPMI interface is sent to the intelligent network card through the network communication connection, so that the intelligent network card establishes a communication connection with the PXE server according to the IP address.

[0084] Further, after the IPMI interface of the bare metal server receives the DHCP Discovery packet sent by the intelligent network card through the network communication connection, the DHCP Discovery packet is submitted to the PXE server through the network communication connection. Then, the PXE server allocates an IP address, and the IP address can be used for communication between the intelligent network card and the PXE server. The DHCP Offer packet returned by the PXE server and containing the IP address received by the IPMI interface is sent to the intelligent network card through the network communication connection.

[0085] The intelligent network card sends a DHCP request confirmation message again after receiving the DHCP Offer message. The IPMI interface of the bare metal server sends the DHCP request confirmation message to the PXE server through the network communication connection after receiving the DHCP request confirmation message from the intelligent network card through the network communication connection, and forwards the confirmation message returned by the PXE server to the intelligent network card through the network communication connection.

[0086] The intelligent network card completes the request for allocating an IP address, obtains the IP address allocated by the PXE server, and can further communicate with the PXE server through the address.

[0087] In step S230, the PXE boot installation file request sent by the intelligent network card is received through the network communication connection, and the PXE boot installation file request is sent to the PXE server through the IPMI interface.

[0088] After receiving the confirmation message, the intelligent network card sends a PXE boot installation file request to the PXE server through the network communication connection. The PXE server sends the pre-deployed PXE boot installation file to the IPMI interface of the bare metal server through the network communication connection, so that the IPMI interface sends the PXE boot installation file to the intelligent network card through the network communication connection, and the intelligent network card completes its own boot and installation.

[0089] In step S240, the PXE boot installation file returned by the PXE server and received by the IPMI interface is sent to the intelligent network card through the network communication connection, so that the intelligent network card performs PXE boot installation through the PXE boot installation file.

[0090] Further, the IPMI interface of the bare metal server receives the PXE boot installation file request sent by the intelligent network card through the network communication connection, and sends the PXE boot installation file request to the PXE server. The PXE server sends the boot installation file to the IPMI interface of the bare metal server through the network communication connection, so that the boot installation file can reach the intelligent network card through the network communication connection. Then, the intelligent network card reads the boot installation file and completes the PXE boot installation of the intelligent network card. The above method improves the efficiency of deploying the intelligent network card and improves the reliability of the PXE boot installation of the intelligent network card.

[0091] Furthermore, the bare metal server's IPMI interface receives the PXE boot installation result sent by the smart network card through the network communication connection, and then sends the PXE boot installation result to the cloud management platform through the IPMI interface, so that the administrator can confirm whether the PXE boot installation of the smart network card was successful based on the PXE boot installation result. At this point, the process of the bare metal server's IPMI interface assisting the smart network card in PXE boot installation via the network communication connection is complete.

[0092] The PXE boot installation method for a smart network interface card (NIC) provided in this invention is applied to a bare-metal server. The bare-metal server establishes a network communication connection between its PCIe channel and the smart NIC. The bare-metal server connects to a cloud management platform via an IPMI interface. The cloud management platform establishes a communication connection with the PXE server. The PCIe channel is bridged with the IPMI interface. The method includes: receiving an instruction from the cloud management platform and controlling the smart NIC to power on; receiving a DHCP request sent by the smart NIC through the network communication connection. The system sends Discovery messages and DHCP Discovery messages to the PXE server via the IPMI interface. It also sends the IP address assigned by the PXE server, received via the IPMI interface, to the smart network interface card (NIC) through the network communication connection, enabling the NIC to establish a communication connection with the PXE server based on the IP address. Furthermore, the system receives PXE boot installation file requests from the NIC via the network communication connection and sends these requests to the PXE server via the IPMI interface. Finally, it sends the PXE boot installation file returned by the PXE server, received via the IPMI interface, to the NIC through the network communication connection, allowing the NIC to perform PXE boot installation using the PXE boot installation file. This communication between the NIC and the bare metal server enables the startup and installation of the NIC system, saving time configuring intermediate network devices and improving the efficiency of NIC deployment.

The cloud management platform establishes a communication connection with a PXE server. The PCIe channel is bridged with the IPMI interface. The device includes:
