GitHub user cookesan added a comment to the discussion: Is secondary management server able to handle infra in data center 1
I would not model these as primary and secondary management servers. In CloudStack they are management-server nodes sharing the CloudStack database and agent connectivity. If only the management server in data center 1 is down, another management server can take over as long as it can reach the same CloudStack database and the data-center-1 hosts, system VMs, and storage management endpoints. The agent code is built around a list of management server addresses and can migrate an agent connection to another reachable management server; the database config is common CloudStack state, not per-zone state. If the whole data center 1 is unreachable, a management server in data center 2 will not be able to provision resources in data center 1 just because it is still running. It still needs network reachability to the hosts and the management/storage networks for that zone. So they do not need to be on the same L2 network, but they do need routable connectivity for the CloudStack control plane: shared database access, API/UI/load-balancer access as you design it, and management-server-to-agent/system-VM reachability for the zones they are expected to control.
