This presentation discussed disaster recovery solutions for business critical applications using VMware Site Recovery Manager (SRM). SRM supports various replication technologies including vSphere Replication, array-based replication, and application-consistent replication options like Oracle Data Guard. SRM automates the failover and failback of virtual machines in protection groups between sites using recovery plans. A demo showed configuring an SAP environment for disaster recovery with SRM and vSphere Replication, including performing a test failover recovery. Another section demonstrated using SRM for a planned migration of VMs from an on-premises data center to a cloud provider.

11. vSphere Provides The Best Foundation For Disaster Recovery
Flexible Infrastructure
• Eliminate need for identical hardware across sites
• Enable waterfalling of equipment to recovery site
Simple Application Protection
• Entire system – including application, OS,
and data – is stored as virtual machine files
• Entire system can be protected with data protection tools
Cost-Efficient Infrastructure
• Reduced hardware requirements at recovery site
• Use recovery hardware to run low-priority apps

26. Protection Group
A protection group:
– Is a group of virtual machines that fail over together to the recovery site
– Contains virtual machines whose data has been replicated by array-based replication or by VR
– Typically contains virtual machines that are related in some way:
• A three-tier application (application server, database server, Web server)
• Virtual machines whose virtual machine disk files are part of the same datastore group

the following:
– Direct attached
– NFS
– iSCSI
– Fibre Channel
