Why does the recommended high-availability solution differ with each PI program?

Question asked by Kenneth_Barber Champion on Jul 28, 2020

To get the PI Asset Framework, the PI Analysis Service, and the PI Notifications Service to be redundant, OSIsoft recommends using Windows Server Failover Clustering. To get the PI Data Archive to be redundant, we use PI Collectives. PI Connectors (Generation 1) use yet another type of failover.

 

Why does the recommended high-availability solution differ with each PI program? What makes the use of Windows Server Failover Clustering inappropriate for the PI Data Archive and for PI Connectors? Or is Windows Server Failover Clustering actually appropriate in all cases?
