技术领域Technical field

本发明涉及通信技术领域，尤其涉及一种裸金属服务器的虚拟网络配置方法、系统及智能网卡。The present invention relates to the field of communication technology, and in particular to a virtual network configuration method, system and intelligent network card for a bare metal server.

背景技术Background technique

裸金属服务器(Bare Metal Server，BMS)，是指未安装操作系统的物理服务器。BMS支持用户自定义安装操作系统(Operating System，OS)。相对于虚拟机，物理服务器具有计算能力强、资源独占、安全隔离等优点。相关技术中，可以使用OpenStack Ironic提供裸金属服务，其中，OpenStack是一个开源的云计算管理平台项目，Ironic是OpenStack的一个子项目，专门用于提供裸机服务。Ironic可以为用户提供自助式的裸金属服务器管理服务。Bare Metal Server (BMS) refers to a physical server without an operating system installed. BMS supports user-defined installation of the operating system (Operating System, OS). Compared with virtual machines, physical servers have the advantages of strong computing power, exclusive resources, and security isolation. Among related technologies, OpenStack Ironic can be used to provide bare metal services. OpenStack is an open source cloud computing management platform project, and Ironic is a sub-project of OpenStack specifically used to provide bare metal services. Ironic can provide users with self-service bare metal server management services.

OpenStack Ironic技术中，对于被管理的裸金属服务器而言，主要包括上架自检阶段(Inspection)、部署阶段(Provision)以及回收阶段(Clean)这三个阶段。上架自检阶段指的是，当物理服务器完成硬件安装、网络连线等工作后，由管理员将裸机的信息注册到Ironic架构中进行纳管。该阶段中，根据需要可以应用Ironic Inspector的功能实现裸机硬件配置信息以及上联交换机信息的自动采集，即裸金属服务器的自检。部署阶段指的是，当物理服务器完成上架后，处于可用状态，租户(或用户)根据业务需要指定镜像、网络等信息创建裸金属服务器实例。回收阶段指的是，当物理服务器完成使用，由租户(或用户)申请释放资源。In OpenStack Ironic technology, the managed bare metal servers mainly include three stages: self-inspection stage (Inspection), deployment stage (Provision) and recycling stage (Clean). The self-inspection stage refers to when the physical server completes hardware installation, network connection, etc., and the administrator registers the bare metal information into the Ironic architecture for management. In this stage, the function of Ironic Inspector can be used as needed to automatically collect bare metal hardware configuration information and uplink switch information, that is, self-inspection of bare metal servers. The deployment phase refers to when the physical server is put on the shelf and is in an available state. Tenants (or users) create bare metal server instances by specifying image, network and other information according to business needs. The recycling phase refers to when the physical server completes its use and the tenant (or user) applies to release resources.

相关技术中，在上架自检阶段和部署阶段，需要通过智能平台管理接口(Intelligent Platform Management Interface，IPMI)配合物理交换机，来配置裸金属服务器的网络信息，以便裸金属服务器能够接入局域网、公网。其中，在上架自检阶段，通过IPMI发现裸金属服务；在部署阶段，用户通过IPMI平台管理工具和物理交换机为裸金属服务器人工配置网络信息。In related technologies, during the self-inspection stage and deployment stage, it is necessary to configure the network information of the bare metal server through the Intelligent Platform Management Interface (IPMI) in conjunction with the physical switch, so that the bare metal server can access the LAN and public network. net. Among them, during the self-inspection stage, bare metal services are discovered through IPMI; during the deployment stage, users manually configure network information for bare metal servers through IPMI platform management tools and physical switches.

相关技术中，需要人工配置裸金属服务器的网络，人工错误对网络连通性影响较大，这导致裸金属服务器的网络的可管理性较差。In related technologies, a network of bare metal servers needs to be manually configured, and manual errors have a greater impact on network connectivity, which results in poor manageability of the network of bare metal servers.

Figure 1 includes a cloud server 11, a controller 12, at least one smart network card 13 and at least one bare metal server 14. One smart network card 13 corresponds to one bare metal server 14.

云服务器11用于管理裸金属服务器，用户可以通过用户终端登录云服务器11，对裸金属服务器进行管理，例如，用户可以根据业务需求申请创建裸金属服务器实例，当用户使用完已经配置好的裸金属服务器时，申请清理裸金属服务器中的数据等。Cloud server 11 is used to manage bare metal servers.

在介绍了裸金属服务器的虚拟网络配置系统的架构之后，下面结合图2详细说明各设备实现虚拟网络配置的具体实现过程。After introducing the architecture of the virtual network configuration system of bare metal servers, the specific implementation process of virtual network configuration for each device will be described in detail below with reference to Figure 2.

图2示出了本发明实施例提供的裸金属服务器的虚拟网络配置系统的一种交互图。下面以控制器和智能网卡为两个分离的独立设备为例进行说明。参见图2，裸金属服务器的虚拟网络配置方法可以包括以下步骤：Figure 2 shows an interaction diagram of the virtual network configuration system of a bare metal server provided by an embodiment of the present invention. The following description takes the controller and smart network card as two separate independent devices as an example. Referring to Figure 2, the virtual network configuration method of a bare metal server may include the following steps:

S201、云服务器获取网络配置请求；所述网络配置请求用于请求配置裸金属服务器的虚拟网络。S201. The cloud server obtains a network configuration request; the network configuration request is used to request the configuration of a virtual network of the bare metal server.

网络配置请求可以包括待配置的裸金属服务器的标识信息和网络需求信息。待配置的裸金属服务器为完成硬件安装、网络连接等预配置操作的裸金属服务器。裸金属服务器的标识信息可以为裸金属服务器的唯一标识信息，例如，设备标识、媒体访问控制(MediaAccess Control Address，MAC)地址等。The network configuration request may include identification information and network requirement information of the bare metal server to be configured. The bare metal server to be configured is a bare metal server that has completed hardware installation, network connection and other pre-configuration operations. The identification information of the bare metal server may be the unique identification information of the bare metal server, for example, device identification, media access control (MediaAccess Control Address, MAC) address, etc.

网络需求信息可以包括网络类型、带宽等。网络类型可以包括：虚拟私有云(Virtual Private Cloud，VPC)、高速网络、自定义虚拟局域网(Virtual Local AreaNetwork，VLAN)网络和无限带宽(InfiniBand，IB)网络，四种网络之间相互隔离不互通。网络需求信息用于供控制器确定网络配置信息。这里，网络需求信息可以是用户输入或选择的，也可以是设定的。Network requirement information may include network type, bandwidth, etc. Network types can include: virtual private cloud (Virtual Private Cloud, VPC), high-speed network, custom virtual local area network (Virtual Local Area Network, VLAN) network and infinite bandwidth (InfiniBand, IB) network. The four types of networks are isolated from each other and cannot communicate with each other. . Network requirement information is used by the controller to determine network configuration information. Here, the network requirement information may be input or selected by the user, or may be set.

在一实施例中，云服务器可以接收用户终端发送的网络配置请求，网络配置请求是用户终端在接收到用户输入或选择的网络配置需求信息时生成的。In one embodiment, the cloud server may receive a network configuration request sent by the user terminal. The network configuration request is generated by the user terminal when it receives network configuration requirement information input or selected by the user.

例如，用户在完成预配置操作之后，可以通过用户终端的用户界面，登录用于管理裸金属服务器的云服务器，选择待配置的裸金属服务器，并根据业务需求输入网络配置需求信息，或从用户界面中选择网络配置需求信息；之后，用户可以通过用户界面触发用户终端向云服务器发送网络配置请求。预配置操作可以包括：组装裸金属服务器的硬件、将虚拟交换机卸载(即安装)在智能网卡中、将智能网卡插入待配置的裸金属服务器的预设接口、建立智能网卡与控制器之间的通信连接等。For example, after completing the preconfiguration operation, the user can log in to the cloud server used to manage bare metal servers through the user interface of the user terminal, select the bare metal server to be configured, and enter network configuration requirement information according to business needs, or obtain the information from the user. Select the network configuration requirement information in the interface; then, the user can trigger the user terminal to send a network configuration request to the cloud server through the user interface. The preconfiguration operation may include: assembling the hardware of the bare metal server, uninstalling (that is, installing) the virtual switch in the smart network card, inserting the smart network card into the preset interface of the bare metal server to be configured, and establishing the connection between the smart network card and the controller. Communication connections, etc.

其中，裸金属服务器的预设接口用于与智能网卡连接。智能网卡在检测到与裸金属服务器成功建立通信连接之后，可以获取裸金属服务器的标识信息，建立智能网卡的标识信息与裸金属服务器的标识信息之间的关联关系。之后，智能网卡可以向控制器发送该关联关系，以便控制器存储该关联关系，或者，智能网卡也可以通过控制器向云服务器发送该关联关系，以便云服务器存储该关联关系。也就是说，智能网卡的标识信息与裸金属服务器的标识信息之间的关联关系，可以存储于云服务器中，也可以存储于控制器中，此处不做限制。Among them, the default interface of the bare metal server is used to connect to the smart network card. After the smart network card detects that the communication connection is successfully established with the bare metal server, it can obtain the identification information of the bare metal server and establish an association between the identification information of the smart network card and the identification information of the bare metal server. Afterwards, the smart network card can send the association relationship to the controller so that the controller can store the association relationship, or the smart network card can also send the association relationship to the cloud server through the controller so that the cloud server can store the association relationship. In other words, the association between the identification information of the smart network card and the identification information of the bare metal server can be stored in the cloud server or in the controller. There is no restriction here.

在另一实施例中，云服务器可以获取资源配置需求信息，基于资源配置信息中的网络配置需求信息生成网络配置请求。In another embodiment, the cloud server may obtain the resource configuration requirement information and generate a network configuration request based on the network configuration requirement information in the resource configuration information.

例如，用户在用户终端的交互界面中选择待配置的裸金属服务器，并根据业务需求输入或选择该裸金属服务器的资源配置需求信息，用户终端在获取到待配置的裸金属服务器的资源配置需求信息的情况下，向云服务器发送获取到的资源配置需求信息。For example, the user selects the bare metal server to be configured in the interactive interface of the user terminal, and inputs or selects the resource configuration requirement information of the bare metal server according to the business requirements. The user terminal obtains the resource configuration requirement of the bare metal server to be configured. In the case of information, the obtained resource configuration requirement information is sent to the cloud server.

资源配置需求信息包括待配置的裸金属服务器的标识信息、镜像类型、网络需求信息等。镜像类型可以是公共镜像、私有镜像或共享镜像。网络需求信息请参照上述相关描述。The resource configuration requirement information includes the identification information, image type, network requirement information, etc. of the bare metal server to be configured. The image type can be public image, private image or shared image. For network requirements information, please refer to the relevant descriptions above.

云服务器在获取到资源配置需求信息的情况下，可以根据资源配置需求信息中的镜像类型，获取与镜像类型相对应的镜像文件，经由控制器以及智能网卡，向待配置的裸金属服务器发送获取到的镜像文件，以便裸金属服务器在获取到镜像文件后，安装镜像文件对应的操作系统。When the cloud server obtains the resource configuration requirement information, it can obtain the image file corresponding to the image type according to the image type in the resource configuration requirement information, and send it to the bare metal server to be configured via the controller and smart network card. The image file is obtained so that the bare metal server can install the operating system corresponding to the image file after obtaining the image file.

裸金属服务器在成功安装操作系统之后，可以经由智能网卡以及控制器，向云服务器发送用于表示裸金属服务器已成功安装操作系统的通知消息。After the bare metal server successfully installs the operating system, it can send a notification message to the cloud server via the smart network card and the controller to indicate that the bare metal server has successfully installed the operating system.

云服务器可以在经由控制器以及智能网卡，向待配置的裸金属服务器发送获取到的镜像文件之后，执行S202；云服务器也可以在获取到用于表示裸金属服务器已成功安装操作系统的通知消息之后，执行S202。The cloud server can execute S202 after sending the obtained image file to the bare metal server to be configured via the controller and the smart network card; the cloud server can also obtain a notification message indicating that the operating system has been successfully installed on the bare metal server.
