� 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 Plan

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

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.

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
