SD-WAN HA
SDWAN is a horizontally scaling solution. Just add more nodes.
Managers
Managers can be deployed in these numbers:
1, 3, 6.
Each set of managers is a cluster. A cluster provides HA.
For redundancy, use multiple clusters.
Disaster recovery
Detailed requirements to implement disaster recovery.
It’s recommended to keep another cluster available as a backup.
The Managers can sync over the datacenter interconnect.
