Detailed Description

The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

The embodiment of the application provides an out-of-band management network construction method for a cloud platform, which is suitable for constructing a network for out-of-band management of a physical server of the cloud platform aiming at the cloud platform.

The cloud platform is generally a server or a server cluster supporting some kind of service operation, for example, a service supporting computing, a service supporting information processing, and the like. As shown in fig. 1A, the hardware architecture of the cloud platform generally includes a service switch 111, and a physical server 112 for implementing data communication through the service switch 111. The number of the physical servers 112 is plural, and the physical servers may be deployed in a centralized manner in a computer room or deployed in a distributed manner.

The software system architecture for implementing the cloud platform can be various, for example, an OpenStack cloud platform system is adopted to deploy the cloud platform. The OpenStack cloud platform may include various types of nodes, such as control nodes, network nodes, storage nodes, and computing nodes. Various types of nodes are implemented by software, and can be integrated in one physical server or a plurality of physical servers. That is, at least one of the control node, the network node, the storage node, and the computing node is configured in one physical server.

In the process that the cloud platform supports service operation, the service operation process needs to be supervised, controlled and maintained so as to ensure normal and safe operation of the service. For example, the operation performance and data indexes of each physical server 112 are monitored and collected, and a control instruction, such as a restart, reset, read-write control instruction, may also be sent to the physical server 112. Therefore, an out-of-band management network needs to be established for the cloud platform, and the out-of-band management network is independent of the cloud platform supporting service operation, so as to perform transaction processing of out-of-band management. Specifically, as shown in fig. 1A, an out-of-band management unit 121 may be configured in the physical server 112, and the out-of-band management unit 121 implements data communication through an out-of-band management switch 122. The out-of-band management unit 121 is configured to perform data interaction through an out-of-band management network to manage the physical server 112.

The Out-of-band management unit 121 may be implemented in hardware and/or software, for example, the Out-of-band management unit may be, optionally, a iLO (Integrated Out-of-band) chip. The iLO chip can realize the remote management of the server at the hardware level, including the startup and shutdown, the restart, the monitoring of the server state, the virtual KVM and the like.

Based on the cloud platform architecture shown in fig. 1A, an embodiment of the present application provides a method for constructing an out-of-band management network of a cloud platform, and a flowchart of the method is shown in fig. 1B. The method is applicable to the architecture of the cloud platform, and can be specifically realized by an out-of-band management network construction device configured in any physical server, and the device can be realized in a hardware and/or software mode.

As shown in fig. 1B, the method includes:

s101, deploying an out-of-band management virtual machine in a host server of the cloud platform, wherein the host server is any physical server in the cloud platform;

generally, one or more virtual machines may be deployed on each physical server of the cloud platform to support various service functions of business operations. In this embodiment, the virtual machine may be deployed for out-of-band management, which is called as out-of-band management virtual machine.

A Virtual Machine, also called a Virtual Machine (VM), refers to a complete computer system with complete hardware system functions, which is simulated by software and runs in a completely isolated environment. The work that can be done in a physical computer can be implemented in a virtual machine. When creating a virtual machine in a computer, it is necessary to use part of the hard disk and memory capacity of the physical machine as the hard disk and memory capacity of the virtual machine. Each virtual machine has an independent CMOS, hard disk and operating system, and can be operated like a physical machine.

The out-of-band management virtual machine can only realize the out-of-band management function, and can also realize the out-of-band management function and other service functions of the cloud platform.

Through the path, bidirectional interaction of data can be realized between the out-of-band management virtual machine 123 and the out-of-band management unit 121, so that the out-of-band management virtual machine 123 can acquire data acquired by the out-of-band management unit 121 in the physical server 112, and can also send an instruction to the out-of-band management unit 121 to control the physical server 112, that is, out-of-band management of the cloud platform is realized. Meanwhile, the out-of-band management virtual machine 123 is connected to the cloud platform network (also referred to as a service operation network or a production network) through the second virtual network bridge 124b and the second physical network card 125b, so that the out-of-band management virtual machine 123 can be accessed through the cloud platform network, and the out-of-band management virtual machine 123 can also directly acquire operation data, such as an operating system log, as data for out-of-band management through the service operation network.

As shown in fig. 1C, the out-of-band management virtual machine 123 is preferably configured in a compute node, and the out-of-band management virtual machine 123 is connected to the first virtual bridge 124a and the second virtual bridge 124b based on data link layer devices (taps) through its two interfaces eth0 and eth1, respectively. The first virtual bridge 124a may be connected to a first physical network card (eth 0) 125a, and thus to the out-of-band management switch (ToR) 122. The second virtual bridge 124b may be connected to the second physical network card (xgbe 0 and xgbe 1) 125b through the virtual network convergence unit (br-int and br-tun) 126 of the virtual switch software (Openvswitch) and the physical network card convergence unit (Bond 0) 127, thereby being connected to the service switch (ToR) 111.

According to the technical scheme of the embodiment of the application, the out-of-band management virtual machine can be connected to the out-of-band management network for out-of-band management by deploying the out-of-band management virtual machine in the physical server of the cloud platform and by means of the physical network card of the physical server. Therefore, the setting of special out-of-band management equipment is reduced, and the hardware cost can be reduced; meanwhile, the out-of-band management virtual machine runs on the physical server, and the physical server is in the cloud platform network, so that the out-of-band management virtual machine can be accessed through the cloud platform network, namely, the out-of-band management virtual machine is remotely accessed through the cloud platform network, and a flexible and convenient control mode is provided; the out-of-band management virtual machine can also directly acquire the operation data of other virtual machines from the cloud platform network; in addition, the limit of the out-of-band management tool software which can be run on the out-of-band management virtual machine is less, so that the maintenance manager can flexibly select the out-of-band management tool software to realize more complex and rich out-of-band management requirements.

Fig. 2A is a flowchart of a method for building an out-of-band management network of another cloud platform according to an embodiment of the present application, and the present embodiment provides a more specific building scheme based on the technical scheme provided in the foregoing embodiment.

For an existing cloud platform system, for example, an OpenStack system, when a virtual machine is created, a bound virtual machine bridge is created for the virtual machine by default, and the virtual machine bridge is connected to a physical network card accessing a cloud platform network. As shown in fig. 2B, the created out-of-band virtual management machine 123 is created with a first virtual bridge 124a and a second virtual bridge 124B by default, both of which are connected to the virtual network convergence units (br-int and br-tun) 126 by default, and the virtual network convergence unit 126 is connected to the second physical network card 125B through the physical network card convergence unit (Bond) 127. In this example, the physical network cards include two types, the second physical network card 125b is a gigabit network card (xgbe 0 and xgbe 1) supporting the service operation network, and the first physical network card 125a is a gigabit network card (eth 0 and eth 1) connected to the out-of-band management network.

In this embodiment, the connection between the first virtual bridge 124a and the virtual network convergence unit 126 is further disconnected, as shown in fig. 1C, and then connected to the first physical network card 125a, that is, connected to the out-of-band management network where the out-of-band management switch 122 is located. And the second virtual bridge 124b remains in communication with the cloud platform network via the second physical network card 125b.

The technical scheme of the embodiment realizes the establishment process of the existing virtual machine and virtual network bridge based on the cloud platform, and can realize the communication between the out-of-band management virtual machine and the out-of-band management network through simple improvement.

As mentioned above, the out-of-band management virtual machine is preferably that the physical network card connected to the out-of-band management switch is a gigabit network card in the host server, and the physical network card connected to the service switch is a gigabit network card in the host server.
