vSphere Replication - provides simple, cost-efficient replication between vSphere clusters
Planned migration - ensures no data-loss, application-consistent migrations of VMs
Reprotect and failback - automates reprotection and failback to original site after failover
User Interface - manage both protected and recovery sites from one interface
IP customisation - faster recovery time if IP customisation is required at the recovery site
VM startup order - more granular control over startup order and dependent relationships
In-guest callouts - run scripts from within protected virtual machines during a failover

Setup resource mappings - map production resources to resources at a recovery site
Create recovery plans - with virtual machine startup order control and IP customisation
Test recovery process - non-disruptively test recovery plans in an isolated environment
Workload mobility - automate planned site migrations and failbacks
Automate failover - automate the execution of recovery plans to ensure accuracy

Create, manage and document - recovery plans within VMware vCenter
Automate promotion - of replicated datastores using array specific adapters
Reconfigure VM IP addresses - to match network configuration at failover site
Use storage snapshots - to perform recovery tests without losing replicated data
Support for virtual machines - that use VMFS and raw disk mappings (RDMs)
Monitor availability - of the remote site and alert users of possible site failures
Bi-directional site protection - supports both sites running active virtual machines
Shared recovery sites - many-to-one pairings of protected sites with a recovery site
