This post is a hand-picked compilation of suggestions from OSIsoft's feedback website that ask for redundancy support to be added to a PI program or for a PI program to be able to send data to PI Collectives. Suggestions to enhance existing redundancy support are excluded. If you agree with any of these suggestions, please consider voting for them!
Some search terms that I used include: failover, redundant, availability, collective
I'm adding this section in response to Roger Palmen's comment. These are the load-balancing suggestions.
Some root words of search terms that I used: balance, distribute
