Topology 4: Things to note

If a PI System is not performing to expectation with the recommended resources and settings, contact the AVEVA Customer Support team to determine if modifications are needed to the Data Archive tuning parameters or the PI Analysis Service configuration settings.

AVEVA PI Vision scalability is specified using concurrent connections, which may not match the number of concurrent users if some users open more than one display at a time. Scaling of concurrent connections is heavily influenced by both the complexity and volume of unique analysis data reference attributes displayed in open PI Vision displays. For optimal performance in PI Vision, Asset Framework (AF) analyses should output to PI points.

Note: In testing, it was discovered that the amount of RAM available on the Data Archive node made a significant impact in overall performance. If performance appears to be slower after significant system configuration changes, adding additional RAM to the Data Archive node may provide some improvement.
