Planning for Disaster Recovery

Considerthefollowingitemsasyousetupadisasterrecoveryprogram:

 Whatisthemaximumdowntimeyoucanaccept?WhatisyourRecoveryTimeObjective(RTO)?

 Howmuchdatalosscanyouaccept?WhatisyourRecoveryPlanObjective(RPO)?

 Whatkindofrecoveryplandoyouneedforapartialdisaster(suchasastoragearrayfailure)compared

toacompletedisaster(suchasanentirefacilitybeingunavailablebecauseoffiredamage)?

 Howdoyouclassifyyourcomputingresourcesforrestorationafteradisaster?Aretheycritical,urgent,

About Protected and Recovery Sites

SRMusestwosites,aprotectedsiteandarecoverysite.TheVirtualCenterServer2.5andtheVIClient2.5must

beinstalledatbothsites,aswellasanSQLServerorOracleDatabaseserver.(SeeSiteRecoveryManager

Technical Note Getting Started with Site Recovery Manager Site Recovery Manager 1.0 and Later This document provides a high‐level overview of VMware® Site Recovery Manager (SRM), a disaster recovery solution from VMware. If a disaster occurs, SRM helps you quickly restore your organization’s IT infrastructure, dramatically shortening the length of time that you experience a business outage. SRM is based on your existing IT setup using virtual machines that VMware VirtualCenter manages.
PAGE 2
Getting Started with Site Recovery Manager About SRM Architecture Each site consists of a VirtualCenter Server, which is a Windows machine that runs the VirtualCenter service. Installed with each VirtualCenter Server is the SRM Server. The SRM Server hosts Site Recovery Manager and array management technology. It also serves the SRM plug‐in to the VI Client. Management is done from the VirtualCenter client on the protected site. SRM uses block‐based replication with SRAs installed on the SRM Server.
PAGE 3
Getting Started with Site Recovery Manager Setting Up SRM The following table describes process of setting up SRM. These steps assume that you already have a working Virtual Infrastructure with VirtualCenter clients installed as well as the SRAs installed and configured. For more information, see the Administration Guide for Site Recovery Manager 1.0. Task Description Prepare the site See “Preparing to Use SRM.
