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 PowerVault MD Series Support Matrix on 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.

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-by- step 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 VMware Fibre Channel SAN Configuration Guide at vmware.com/ 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 at vmware.com/support/pubs
NOTE: To select appropriate VMware document based on the VMware versions, see the Compatibility Requirements document.
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).
