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.Thisintegrationofhardwareand
softwaresupportsthemostdemandingapplicationbusinesscontinuanceneeds,inthiscase,afailover
followingadisaster.AnexampleofSRMarchitectureisillustratedinFigure 1

Preparing to Use SRM
AnenvironmentthatisreadyforSRMincludesthefollowing.
 Theprotectedandrecoverysitesareidentified.
 ProtectedvirtualmachinesresidinginhostsorclustersaremanagedbyVirtualCenterServer2.5,andare
residingonasupportedESXServer.
Forinformationaboutthemostrecentupdatesandpatchlevels,consulttheSiteRecoveryManager
CompatibilityMatrixesdocumentation.
 AMicrosfotSQLServerEnterprise2005orOracleDatabase10gserverisreadyforuseontheprotected
andrecoverysites.
 Array‐basedreplication(iSCSIorFibreChannelstoragearray)isinstalledandconfiguredattheprotected
andrecoverysites.Ifothervendor‐providedcomponentsarerequired,thecomponentsareinstalled.
 TheSRMservermusthaveaccesstoaVirtualCenterserverthatmanagesESXhoststhathaveaccessto
volumesmanagedbythereplicatedarrays.
 Administratorrolesandpermissionsareidentifiedfortheadministratorswhowillinstall,configure,
setup,test,andmanageSRM.
