Installing and conguring the SRA
The Dell EMC ME4 Series Storage Replication Adapter (SRA) for vSphere enables full-featured use of the VMware vCenter Site Recovery
Manager (SRM) version 6.5 or later. Combining the ME4 Series storage system’s replication functionality with the vCenter SRM, the SRA
provides an automated solution for implementing and testing disaster recovery between geographically separated sites. It also enables you
to use SRM for planned migrations between two sites.

About VMware Site Recovery Manager
The vCenter Site Recovery Manager (SRM) is a business continuity and disaster recovery solution that helps you plan, test, and execute
the recovery of vCenter virtual machines between one site (the protected site) and another site (the recovery site).
Two types of recovery are available—planned migration and disaster recovery.
Planned migration
Planned migration is the orderly decommissioning of virtual machines at the protected site and commissioning of equivalent machines at
the recovery site. For planned migration to succeed, both sites must be up and fully functioning.
Disaster recovery
Disaster recovery is similar to planned migration except it does not require that both sites be up. During a disaster recovery operation,
failure of operations on the protected site are reported but otherwise ignored.
SRM coordinates the recovery process with the underlying replication mechanisms that the virtual machines at the protected site are shut
down cleanly (in the event that the protected site virtual machines are still available) and the replicated virtual machines can be powered
up. Recovery of protected virtual machines to the recovery site is guided by a recovery plan that species the order in which virtual
machines are started up. The recovery plan also species network parameters, such as IP addresses, and can contain user-specied scripts
that can be executed to perform custom recovery actions.
After a recovery has been performed, the running virtual machines are no longer protected. To address this reduced protection, SRM
supports a reprotect operation for virtual machines. The reprotect operation reverses the roles of the two sites after the original protected
site is back up. The site that was formerly the recovery site becomes the protected site and the site that was formerly the protected site
becomes the recovery site.
