使用 VMware 和 Dell MD 存储阵列进行数据恢 复
为了整合并更有效地利用服务器资源，以前运行在专用物理服务器环境中的许多应用程序，正在迁移至虚拟机
VM）或运行在基于 VMware ESX 的虚拟基础架构的虚拟服务器上。从这种单独的专用服务器平台，特别是要
（
求高性能、块级存储的生产环境，迁移走的优势包括：
• 更高的可用性
• 增强的灵活性
• 可扩展性
VMware 的 vCenter Site Recovery Manager（SRM）提供采用 Dell PowerVault MD 存储阵列的远程复制功能的灾
难恢复解决方案 (DRS)，来提供服务器和虚拟机的自动故障转移，以及它们所用的基本存储和数据存储。这种
自动恢复解决方案旨在实现以下两个目标：
1. 提供低成本的第 2 层和第 3 层应用程序。
2. 将 DRS 引入到较小型的企业，通常不需要企业级存储和服务。
SRM Overview
NOTE:
The Dell PowerVault SRA can be used on MD Storage Arrays based on both Fibre Channel and iSCSI
configurations.
For more information about supported versions of SRM and MD Storage Arrays, see the Support Matrix at
dell.com/powervaultmanuals.
SRM is a recovery workflow product that automates setup, failover or failback, reprotect and testing of recovery plans.
SRM leverages the Dell MD storage array's block-based Remote Replication feature by using an MD-specific Storage
Replication Adapter (SRAs), which is a set of hardware applications vendor to control replication of data from the
primary site to the recovery site. The figure below shows that the hierarchical relationship of the database, operating
system, VMware applications and storage array in the SRM architecture.

Setting Up Your Environment
This section details initial setup requirements for using VMware vCenter Site Recovery Manager (SRM) and the Dell MD
storage array-based Storage Replication Adapter (SRA).
Installation Prerequisites
Implementing a successful recovery solution using VMware and the remote replication features of the Dell MD storage
array requires specific installation and configuration tasks on the VMware application platform and MD storage array.
The following VMware platforms are required.
• ESX host server (connected to MD storage arrays)
• vSphere Client
• vCenter Server
• Site Recovery Manager (SRM)
• Storage Replication Adapter (SRA)
Compatibility Requirement
NOTE: For the latest supported software VMware versions for vSphere Client, vCenter Server, Site Recovery
Manager, Storage Replication Adapter and firmware updates, see
dell.com/support/manuals.
Before the installation, note the following compatibility requirement.
• vSphere Client and Site Recovery Manager (SRM) version must match with the version of vCenter Server that it is
connecting to. If a different version of vCenter Server is found, it will prompt to download a new client from that
vCenter Server.
NOTE: For information on installing these applications, refer to the VMware platform documentation at
vmware.com/support/product-support.

Remote Replication And Snapshot Premium Feature Activation
SRA requires that these Dell MD storage array premium features be activated on each array used in your recovery
solution:
• Remote Replication
• Snapshot Virtual Disk
For more information on obtaining and activating MD premium features, go to dell.com/support and select your array
model from the product selector.

Dell MD Storage Array Installation Requirements
SRM relies on the MD storage array's Remote Replication premium feature to maintain data replication between the
protected site and the recovery site. Replication must be configured on the MD storage array before configuring SRM.
See the corresponding Deployment Guide for your storage array at dell.com/support/manuals.
虚计磁计布局注意事计
计置计程复制之前，不计要考计计留在数据存计上的虚计机，也要考计计留在虚计磁计上的数据存计。MD 存
计计列上的计程复制功能计运行于虚计磁计计计上；因此，任何计留在复制虚计磁计上的数据存计或虚计机都
受到保计。如果没有虚计机需要保计，计确保您的虚计机至数据存计至虚计磁计计计得很有效。例如，在计虚
计磁计复制示意计中，
保计。如果计建包含计数据存计的计虚计磁计，所有四个虚计机都会受到保计，但是，要以通计网计计接将
400 GB 数据复制到计程存计计列计代价。
400 GB 虚计磁计用于容计包含四个虚计机的计数据存计。然而，只有 VM1 和 VM4 需要

使用相同的保计要求，多虚计磁计复制示意计计示了计建多虚计磁计，并且只复制需要保计的虚计机。 其计
果是，如果必要的计，不但提高了控制计个 VM1 或 VM4 故障计移的能力，而且通计网计移计的数据量更少。

Setting Up Remote Replication On The MD Storage Array
NOTE: You must activate the Remote Replication premium feature before performing the steps below. For step-bystep instructions on using MD Storage Manager (MDSM) to set up Remote Replication, see the Administrator's
Guide for your array at dell.com/support/manuals.
Before installing and configuring SRM, you must set up Remote Replication on each MD storage array used in the
recovery solution.
NOTE: Setup of Remote Replication on iSCSI based PowerVault storage MD Series array is governed by iSCSI
array documents available on dell.com/support/manuals.
To set up Remote Replication on the storage array:
1. Start MD Storage Manager (MDSM) on your management host.
2. Open the Enterprise Management Window (EMW) and discover both the protected and recovery site's storage
array.
3. Open the Array Management Window (AMW) for the protected site's storage array and identify a virtual disk to be
used in the recovery solution.
4. Open the AMW for the recovery site's storage array and create a similar-sized, remotely replicated virtual disk.
5. Right-click on the protected site's storage array virtual disk and select Create Remote Replication
6. Select the settings appropriate for your environment and allow remote replication to synchronize.
7. Repeat these steps for:
a. Each virtual disk to be remotely replicated
b. Each storage array in the recovery solution

Switch Zoning Requirements
Switches used in a fibre-channel and iSCSI configuration must employ zoning. These switch zoning requirements must
be observed:
• Each host bus adapter (HBA) on the host server must connect to a separate switch zone; no more than one HBA may
be connected to one logical switch zone.
• Port 3 on each of the MD storage array controller is reserved for Remote Replication. This is required for fibrechannel only. iSCSI does not require any dedicated port.
• For fibre-channel, a separate zone must be created for each Remote Replication port.
• No more than four data paths (port-to-port segments) can be established from a single, physical host server to a
single RAID controller.
For additional MD storage array zoning information, see the Deployment Guide for your array at dell.com/support.
For additional VMware-related zoning information, see
support/product-support.

Installing The Recovery Solution Components
The recovery solution described in this guide is based on the concept of a protected main site (host server or virtual
machine) connected to an identically configured recovery site ready to take over should the protected site become
unavailable. For this type of failover to be possible, both sites must have independent installations of the required
recovery solution components. The procedures in this section guide you through the installation of these solution
components on the protected site and the recovery site:
• A standalone database with a connection to both vCenter Server and SRM Server
• vCenter Server
• vSphere Client
• vCenter Site Recovery Manager (SRM)
• Storage Replication Adapter (SRA)
NOTE: For more information, see Compatibility Requirements under Installation Prerequisites section of this
document.
About This Guide
This guide describes how to set up the recovery solution in vSphere, as well as how to configure certain SRM settings
required by SRA to discover the MD storage arrays and recognize Remote Replication connections. However, it does not
provide step-by-step instructions for installing VMware platforms. For complete installation information on these
platforms, see the following VMware documentation:
•
VMware Site Recovery Manager Administration Guide
•
VMware vSphere Installation and Setup Guide
•
ESXi and vCenter Server Documentation Center
NOTE: To select appropriate VMware document based on the VMware versions, see the Compatibility
Requirements document.
at vmware.com/support/pubs
Summary Of Tasks
These tasks represent a high-level view of the recovery solution installation and configuration process:
NOTE: Each of these tasks must be completed separately on both the protected and recovery sites.
1. Install a supported database server and configure ODBC (Open Data Base Connectivity) connections.
2. Install vCenter Server
3. Install vSphere Client
4. Install SRM
5. Install the SRM Plug-in (in vSphere).
