The method for obtaining the information of the physical machine is described in detail below.

In the physical machine, a simple operating system can be pre-installed, which can control the physical machine to start or restart, and support input and output operations. For example, when the physical machine is connected to the switch, the simple operating system can connect the The information of the physical machine is sent to the management platform. Wherein, the simple operating system may be a customized or tailored computer operating system, for example, a customized or tailored LINUX system.

After the above-mentioned simple operating system is installed on the physical machine, after receiving the command sent by the management platform or the switch, the physical machine can obtain the information of the physical machine and send it to the switch or the management platform. Let's make a further introduction below.

For the MAC address of the network card of the physical machine, and the port of the switch connected to the network card:

After the physical machine is connected to the switch, the switch can obtain information such as the MAC address of the PXE network card of the physical machine or the MAC address of the service network card through the LLDP protocol. After receiving the LLDP message sent by the physical machine, the switch stores it. The LLDP message includes information such as the MAC address of the PXE network card of the physical machine or the MAC address of the service network card.

The SDN controller can query the switch for the MAC address of the network card of the physical machine and the information of the port of the switch it is connected to, and store them. For example, the controller queries the LLDP information stored by the switch, where the LLDP information can include the physical machine. The MAC address of the network card and the port number of the switch connected to the network card. The SDN controller can generate a physical topology based on LLDP information and record LLDP information. Among them, the SDN controller can query at a set period, or the switch can also directly send the LLDP information to the SDN controller after receiving the LLDP information uploaded by the physical machine, and the SDN controller can receive the physical machine Store the MAC address of the network card and the port information of the corresponding connected switch.

The SDN controller can send the MAC address of the network card of the physical machine and the port information of the switch it is connected to to the management platform. For example, it can notify the network management module of the management platform of the LLDP information obtained from the switch, and the management platform records the The information of each physical machine, for example, respectively records the MAC addresses of the network cards of each physical machine. The SDN controller may also send the information of the physical machine to the management platform after receiving the information acquisition request of the physical machine sent by the management platform.

In another implementation, when the physical machine is connected to the switch, the switch can use the switch number of the switch to which the PXE network card of the physical machine is connected, and the port number of the port of the switch that is connected, or the service number of the physical machine The switch number of the switch connected to the network card or the PXE network card, and the port number of the port connected to the switch are sent to the physical machine, and the physical machine can store these information, for example, in LLDP information. The management platform can obtain the MAC address of the network card of the physical machine stored in each physical machine and the port information of the corresponding connected switch from the connected physical machine. For example, the management platform can send a request to the physical machine through the LLDP protocol. The request is used to obtain the MAC address of the network card of the physical machine and the information of the port of the switch that is connected to it. After receiving the request, the physical machine sends the MAC address of the network card of the physical machine and the port of the switch that is The information is sent to the management platform, for example, carried in LLDP information and sent to the management platform. It should be known that the management platform and the physical machine can be connected through an access switch.

For physical machine specifications, or physical machine identifiers, and other physical machine information:

After a simple operating system is installed on the physical machine, the management platform can send an acquisition command of the physical machine to the physical machine. sent to the management platform.

It should be noted that the method of obtaining information of the physical machine such as the specification parameter of the physical machine or the identifier of the physical machine is only an example, and other methods capable of obtaining information of the physical machine are included in the embodiments of the present invention.

220. Receive an operating system installation instruction. Wherein, the operating system installation instruction may include target physical machine information, operating system type, service network information, and so on.

The management platform can present the pre-acquired physical machine information, operating system type information, network type and other information to the user or administrator through the management interface module, so that the user or administrator can select the target physical machine according to the information of the physical machine. Wherein, information such as type information of the operating system and network type may also be pre-collected by the management platform.

The management platform can receive operating system installation instructions through the management interface module. For example, the management interface module can provide the following options: whether the operating system is Windows7, XP, or Linux, etc.; the CPU model of the physical machine, the size of the internal memory, the model size of the hard disk, etc.; Select the requirements for parameters such as network speed and network type (VLAN, VxLAN, other physical or virtual networks, etc.) of the business network. Wherein, the operating system installation instruction may carry information such as the operating system type selected by the user through the management interface module, the specification parameters of the physical machine, and the network type.
