将 VMware/物理服务器复制到辅助本地站点的体系结构Architecture for VMware/physical server replication to a secondary on-premises site
本文介绍使用 Azure Site Recovery 设置将本地 VMware 虚拟机 (VM) 或物理 Windows/Linux 服务器复制（用于灾难恢复）、故障转移以及恢复到辅助 VMware 站点时使用的体系结构和过程。This article describes the architecture and processes used when set up disaster recovery replication, failover, and recovery of on-premises VMware virtual machines (VMs) or physical Windows/Linux servers to a secondary VMware site using Azure Site Recovery.
体系结构组件Architectural components
| 区域Area | 组件 Component | 详细信息Details |
|---|---|---|
| AzureAzure | 使用 InMage Scout 部署此方案。You deploy this scenario using InMage Scout. | 若要获取 InMage Scout，需要 Azure 订阅。To obtain InMage Scout you need an Azure subscription. 创建恢复服务保管库后，可以下载 InMage Scout 并安装最新的更新，以设置部署。After you create a Recovery Services vault, you download InMage Scout and install the latest updates to set up the deployment. |
| 进程服务器Process server | 位于主站点Located in primary site | 可以部署进程服务器来处理缓存、压缩和数据优化操作。You deploy the process server to handle caching, compression, and data optimization. 它还可以将安装的统一代理推送到要保护的计算机。It also handles push installation of the Unified Agent to machines you want to protect. |
| 配置服务器Configuration server | 位于辅助站点Located in secondary site | 配置服务器可以通过管理网站或 vContinuum 控制台管理、配置和监视部署。The configuration server manages, configure, and monitor your deployment, either using the management website or the vContinuum console. |
| vContinuum 服务器vContinuum server | 可选。Optional. 安装在配置服务器所在的同一位置。Installed in the same location as the configuration server. | 它提供一个控制台用于管理和监视受保护的环境。It provides a console for managing and monitoring your protected environment. |
| 主目标服务器Master target server | 位于辅助站点Located in the secondary site | 主目标服务器保存复制的数据。The master target server holds replicated data. 它从进程服务器接收数据，在辅助站点中创建副本地器，并保存数据保留点。It receives data from the process server, creates a replica machine in the secondary site, and holds the data retention points. 需要的主目标服务器数目取决于要保护的计算机数目。The number of master target servers you need depends on the number of machines you're protecting. 如果希望故障转移到主站点，则主站点上也需要有一个主目标服务器。If you want to fail back to the primary site, you need a master target server there too. 在此服务器上安装统一代理。The Unified Agent is installed on this server. |
| VMware ESX/ESXi 和 vCenter 服务器VMware ESX/ESXi and vCenter server | VMs 托管在 ESX/ESXi 主机上。VMs are hosted on ESX/ESXi hosts. 主机通过 vCenter 服务器进行托管Hosts are managed with a vCenter server | 需要使用 VMware 基础结构来复制 VMware VM。You need a VMware infrastructure to replicate VMware VMs. |
| VM/物理服务器VMs/physical servers | 安装在要复制的 VMware VM 和物理服务器上的统一代理。Unified Agent installed on VMware VMs and physical servers you want to replicate. | 该代理充当所有组件之间的通信提供程序。The agent acts as a communication provider between all of the components. |
复制过程Replication process
- 在每个站点（配置、进程、主目标）中设置组件服务器，并在要复制的计算机上安装统一代理。You set up the component servers in each site (configuration, process, master target), and install the Unified Agent on machines that you want to replicate.
- 在初始复制之后，每台计算机上的代理会将增量复制更改发送到进程服务器。After initial replication, the agent on each machine sends delta replication changes to the process server.
- 进程服务器将优化这些数据，并将其传输到辅助站点上的主目标服务器。The process server optimizes the data, and transfers it to the master target server on the secondary site. 配置服务器将管理复制进程。The configuration server manages the replication process.
