Managed Replication Requirements
Each Storage Center that participates in the Live Volume and managed replication configuration must meet specific
requirements.
● The primary and secondary Storage Centers (Live Volume) must be running version 6.5 or later and meet the Live Volume
requirements.
● The destination Storage Center (managed replication) must be running version 6.5 or later and meet the replication
requirements.
Creating Live Volumes
Create a Live Volume to replicate a volume to another Storage Center while allowing servers to send IO for the volume to both
Storage Centers. This additional flexibility can be used to perform planned outages without interrupting volume availability.
