The intelligent network card 13 may be installed as a hardware component in the bare metal server 14, or may be connected to the bare metal server 14 as a separate device. The virtual switch may be deployed in the intelligent network card 13, that is, the virtual switch is pre-offloaded in the intelligent network card.
Having introduced the architecture of the virtual network configuration system of the bare metal server, a detailed description of the implementation of the virtual network configuration by each device is provided below in conjunction with fig. 2.
Fig. 2 shows an interaction diagram of a virtual network configuration system of a bare metal server according to an embodiment of the present invention. The following description will take the controller and the intelligent network card as two separate independent devices as an example. Referring to fig. 2, the virtual network configuration method of the bare metal server may include the steps of:
s201, a cloud server acquires a network configuration request; the network configuration request is for requesting configuration of a virtual network of the bare metal server.
The network configuration request may include identification information and network demand information of the bare metal server to be configured. The bare metal server to be configured is a bare metal server for completing the pre-configuration operations such as hardware installation, network connection and the like. The identification information of the bare metal server may be unique identification information of the bare metal server, for example, a device identification, a media access control (Media Access Control Address, MAC) address, etc.
The network demand information may include network type, bandwidth, etc. The network types may include: virtual private cloud (Virtual Private Cloud, VPC), high-speed network, custom virtual local area network (Virtual Local Area Network, VLAN) network and InfiniBand (IB) network, which are isolated from each other and not interworking. The network requirement information is used by the controller to determine network configuration information. Here, the network demand information may be input or selected by the user, or may be set.
In an embodiment, the cloud server may receive a network configuration request sent by the user terminal, where the network configuration request is generated when the user terminal receives the network configuration requirement information input or selected by the user.
For example, after the user completes the pre-configuration operation, the user may log in a cloud server for managing the bare metal server through a user interface of the user terminal, select the bare metal server to be configured, and input network configuration requirement information according to service requirements, or select the network configuration requirement information from the user interface; and then, the user can trigger the user terminal to send a network configuration request to the cloud server through the user interface. The pre-configuration operation may include: assembling hardware of the bare metal server, unloading (i.e. installing) the virtual switch in the intelligent network card, inserting the intelligent network card into a preset interface of the bare metal server to be configured, establishing communication connection between the intelligent network card and the controller, and the like.
The preset interface of the bare metal server is used for being connected with the intelligent network card. After the intelligent network card detects that the communication connection with the bare metal server is successfully established, the identification information of the bare metal server can be acquired, and the association relation between the identification information of the intelligent network card and the identification information of the bare metal server is established. The intelligent network card may then send the association to the controller so that the controller stores the association, or the intelligent network card may also send the association to the cloud server through the controller so that the cloud server stores the association. That is, the association relationship between the identification information of the intelligent network card and the identification information of the bare metal server may be stored in the cloud server or in the controller, which is not limited herein.
In another embodiment, the cloud server may obtain the resource configuration requirement information and generate the network configuration request based on the network configuration requirement information in the resource configuration information.
For example, a user selects a bare metal server to be configured in an interactive interface of the user terminal, and inputs or selects resource configuration requirement information of the bare metal server according to service requirements, and the user terminal sends the acquired resource configuration requirement information to the cloud server when acquiring the resource configuration requirement information of the bare metal server to be configured.
The resource allocation requirement information includes identification information, mirror type, network requirement information, etc. of the bare metal server to be configured. The image type may be a public image, a private image, or a shared image. The network requirement information is described above.
Under the condition that the cloud server acquires the resource configuration requirement information, an image file corresponding to the image type can be acquired according to the image type in the resource configuration requirement information, and the acquired image file is sent to the bare metal server to be configured through the controller and the intelligent network card, so that the operating system corresponding to the image file is installed after the bare metal server acquires the image file.
After the bare metal server successfully installs the operating system, a notification message indicating that the bare metal server has successfully installed the operating system may be sent to the cloud server via the intelligent network card and the controller.
The cloud server may execute S202 after sending the obtained image file to the bare metal server to be configured via the controller and the intelligent network card; the cloud server may also perform S202 after acquiring a notification message indicating that the bare metal server has successfully installed the operating system.
S202, the cloud server sends the network configuration request to the controller to trigger the controller to distribute network configuration information for the bare metal server to be configured.
And S203, the controller receives the network configuration request and distributes network configuration information for the bare metal server to be configured.
The controller may allocate network configuration information based on the network demand information in the resource configuration request. The network configuration information may include IP addresses, subnet masks, gateway addresses, DNS server addresses, and the like.
S204, the controller sends the network configuration information to the intelligent network card.
After the intelligent network card and the bare metal server are successfully connected in a communication manner, the association relationship between the identification information of the intelligent network card and the identification information of the bare metal server is stored in the controller or the cloud server, so that the controller can acquire the association relationship between the identification information of the intelligent network card and the identification information of the bare metal server from the local or cloud server, and determine the identification information of the intelligent network card corresponding to the bare metal server to be configured based on the association relationship between the identification information of the intelligent network card and the identification information of the bare metal server, thereby sending network configuration information to the intelligent network card according to the determined identification information of the intelligent network card.
S205, the intelligent network card acquires network configuration information sent by the controller.
The network configuration information sent by the controller can be transmitted through a physical network port of the intelligent network card, and the intelligent network card can acquire the network configuration information received by the physical network port.
Wherein, before executing S205, the intelligent network card may further execute the following pre-configuration steps:
after the intelligent network card is successfully accessed to a bare metal server to be configured, a virtual network port is created, wherein the virtual network port is used for the bare metal server to configure a virtual network corresponding to the virtual network port according to the network configuration information;
the intelligent network card obtains two internet protocol addresses (Internet Protocol Address, IP addresses) belonging to different network segments, and creates a service network and a management network according to the two IP addresses belonging to different network segments; the service network characterizes a physical network carrying the virtual network and is used for transmitting data packets of a virtual network port corresponding to the virtual network after the bare metal server successfully configures the virtual network; the management network characterizes a physical network carrying communications between the cloud server, the controller, and the bare metal server for transmitting the network configuration information. Here, the management network is used to manage or control the bare metal server. That is, control information related to the bare metal server is transmitted through the management network.
It should be noted that, the intelligent network card can create a plurality of virtual network interfaces for the bare metal server, and the bare metal server does not need to add a physical network card, so that the cost can be saved. The maximum number of virtual network ports is limited by the number of physical network ports of the intelligent network card.
Referring to fig. 3, fig. 3 shows another system architecture schematic provided by the embodiment of the present invention, where an intelligent network card may be connected to a bare metal server through a hardware interface, and the intelligent network card may be connected to a switch through a physical network port C1 and/or C2, and the switch is used to build a local area network. It should be noted that the intelligent network card includes at least one physical network port, and the intelligent network card shown in fig. 3 includes two physical network ports, and in some embodiments, the intelligent network card may also include more or fewer physical network ports. In the following, an example of creating 1 virtual portal by using the intelligent network card will be described with reference to fig. 3.
After the intelligent network card and the bare metal server successfully establish communication connection and the driver is successfully installed, a virtual network port (or SRIOV VF) corresponding to the physical network port C1 shown in fig. 3 can be created according to a virtual network port creation instruction triggered by a user, and a presentation port (representator port) B corresponding to the virtual network port is created. The representation port B corresponding to the virtual network port is a virtual port. The virtual network port creation instruction may include the number of virtual network ports to be created, so that the intelligent network card may create a corresponding number of virtual network ports, so that the bare metal server may configure a virtual network corresponding to the virtual network ports according to corresponding network configuration information.
After the intelligent network card successfully installs the driver, when two IP addresses belonging to different network segments are acquired, the two IP addresses can be respectively distributed to two physical network ports C1 and C2, and a service network and a management network are created. For example, the physical network port C1 corresponds to a service network, and the physical network port C2 corresponds to a management network. Here, one IP address corresponds to one physical portal. The intelligent network card acquires network configuration information sent by the controller through the physical network port C2.
The management network is used for the cloud server and the controller to transmit control information corresponding to the bare metal server, such as network configuration information, a flow table sent to the intelligent network card by the controller, and the like. The service network is used for transmitting the data packet of the virtual network port corresponding to the virtual network after the virtual network of the bare metal server is successfully configured. That is, the data packets transmitted through the virtual network card a, the representation port B corresponding to the virtual network port, and the physical network port C1 in fig. 3 are transmitted to the switch through the service network. The data packet via the physical network port C2 is transmitted through the management network.
The virtual network card A is obtained by mapping the representation port B based on the virtual network port when the representation port B corresponding to the virtual network port of the intelligent network card is detected after the bare metal server successfully installs the operating system. Although the virtual port B is a virtual port, the virtual port B is actually present with respect to the virtual network card a.
S206, the intelligent network card sends the network configuration information to the bare metal server based on the virtual switch; the virtual switch is pre-offloaded in the intelligent network card.
The virtual switch in the intelligent network card may be used to forward network configuration information from the controller to the bare metal server.
In fig. 3, a virtual switch in the intelligent network card may control the virtual network card a, and when the intelligent network card obtains the network configuration information sent by the controller via the physical network port C2, the virtual switch in the intelligent network card may forward the network configuration information received from the physical network port C2 to the virtual network card a for use by the bare metal server, so that the bare metal server may obtain the network configuration information transmitted via the virtual network card a.
S207, the bare metal server acquires the network configuration information and configures a virtual network according to the network configuration information.
After the bare metal server successfully installs the operating system, the virtual network of the bare metal server is configured according to the acquired network configuration information. For example, the bare metal server may configure, according to the obtained network configuration information, a virtual network corresponding to the virtual network card a mapped by the representation port B corresponding to the virtual network port.
For example, the bare metal server may configure the IP address, subnet mask, gateway address, DNS server address, etc. of the virtual network card a according to the network configuration information, and after the configuration is successful, the virtual network corresponding to the virtual network card a may be successfully created.
