Topology 3 is a six-server system designed as the largest, stand-alone PI System. If this topology does not meet your system’s requirements, a group of federated PI Systems can be implemented.
There are three versions of Topology 3 covered in this section. The one you select depends on the number of events your PI System is expected to handle:
-
Topology 3A is recommended for systems that have up to 50,000 events per second.
-
Topology 3B is recommended for systems that have between 50,000 and 150,000 events per second.
-
Topology 3C is recommended for systems that have between 150,000 and 250,000 events per second.
