I’m exploring a setup where two Niagara N4 servers (either physical or VMs) run in a Windows Server Failover Cluster (WSFC). The idea is to use a Synology SAN (via iSCSI) or a similar shared storage solution to provide high-speed disk access and enable automatic failover between nodes.
Has anyone implemented this type of configuration? A few specific questions:
-
How does WSFC handle Niagara host IDs in a failover scenario?
-
When the active node fails and the passive node takes over, does Niagara continue to use the same host ID, since only one server is active at a time?
-
During the initial install, do I need to purchase two separate host IDs/licenses, or can a single host ID work across the clustered pair?
Any experiences, caveats, or recommendations for Niagara N4 + WSFC with Synology (or other SANs) would be greatly appreciated.
