� Understanding components of DR
� Introduction to VMware Site Recovery Manager (SRM)
� Key SRM Concepts
� SRM Demo
� Business Benefits of SRM
DR – What are the components involved?
Management
Simplify and automate setup, testing, and execution of recovery process
Lower RTO and increase reliability
Data
Protection of all data – configuration, OS, and application
Infrastructure
Reduce cost and complexity of providing infrastructure necessary to ensure successful recoveryInfrastructure
VMware Site Recovery Manager
Simplifies and automates disaster recovery workflows:
Setup, testing, failover
Turns manual recovery runbooks into automated recovery plans
Provides central management of recovery plans from VirtualCenter
Works with VMware Infrastructure to provide process automation for disaster recovery
Site Recovery Manager leverages VMware Infrastructure to deliveradvanced disaster recovery management and automation

Site Recovery Manager Recovery Plans:Turn manual BC/DR run books into an automated process
Specify the steps of the recovery process in VirtualCenter
Provide a way to test your BC/DR plan in an isolated environmentat the recovery site without impacting the protected VMs in the protected site
Low PriorityVM Recovery
Post Test Cleanup
Virtual Disk Reset
Testing a Recovery Plan
‘Test’ a recovery plan by simulating a failover of protected VMs with zero downtime to the protected VMs in the protected site
Executing Failover
WARNING - Executing an actual failover will permanently alter virtual machines and infrastructure of both the protected and recovery sites

Failback Options in Site Recovery Manager 1.0
�Site Recovery Manager 1.0 does not provide a push-button automated failback process.
�Failback Options:Without SRM (no startup order, no failback history reports)
Work with your storage team, reverse data replication
VM re-inventory*, restart and re-ip (manual or scripted)
With SRM (start up order in recovery plan with failback history)
Work with your storage team, reverse data replication
Leverage SRM, complete all SRM workflows in the reverse direction from Recovery Site back to the Protected Site
Repeat the above two steps from the Protected Site back to the recovery Site.
* Note: VM re-inventory in VC may not be necessary in the Protected site.
Demo
Business Benefits of SRM
Rapid� Automate recovery process� Eliminate failures due to hardware dependencies� Integrate different components of recovery
Reliable� Enable easier, more frequent testing� Turn manual, inconsistent processes into
pre-programmed, repeatable processes
Manageable� Centralize and simplify management of recovery plans� Make disaster recovery protection a property of
virtual infrastructure
Affordable� Eliminate idle recovery hardware� Eliminate dependencies on physical infrastructure
