We are going to a 2 server PI HA environment in the near future and was wondering if there were any pitfalls to avoid or lessons learned you could share from people who have been through it.
Our current PI environment is a single server with approx 30 interfaces connected. We will be going to a dual HA environment with new IP's. All our server utilize SAN disk.
One of my biggest question is on the interface side of it. Do we need to upgrade all our interface software to allow for HA or do we just point the SDK server name to the PI Collective instaead of a specific PI server name.
