In SRM 5.8, new APIs appeared to create protection groups, assign them to recovery plans, and protect virtual machines using array‐based or host‐based replication. The new APIs provide three types of functionality for vSphere disaster recovery operations:

Infrastructure
workflows to create protection groups
workflows to create inventory mappings between matching objects
workflows to add protection groups to recovery plans
Virtual machine (VM) protection
workflows to protect VMs using a pre‐configured array‐based protection group
workflows to protect VMs using a pre‐configured host‐replicated protection group
Virtual machine (VM) recovery settings
recovery priority
per‐VM callouts
final power state
