Hi everybody,

I'm planning to set up new PI System. Its architecture is depicted as above image. My PI Server is standalone (no HA / Collective). I will config 2 computers (install PI OPC DA interface). Each computer runs simultaneous 2 instances to collect 2 separate OPC servers.


Is this system possible? Can I enable both "UniInt failover" and "OPC server-level failover" mode to these interfaces?
