VRA Configuration Best Practices
Zerto best practice: Install a VRA on each source and target hypervisor node on which the protected Oracle VM can run. There will be a break in replication if the Oracle VM is moved to a hypervisor without a VRA.
Zerto best practice: If multiple Oracle virtual machines that are all highly transactional in their I/O profile require protection, distribute the load evenly between hypervisor hosts, and therefore VRAs, to minimize the I/O load placed on a single appliance.
