For distributed systems with large workloads and point counts and with multiple Data Archive servers that link to a central PI AF database, we recommend that you:
-
Install Data Archive in a collective deployment. See Buffering and High Availability.
-
Install PI AF server using an approach based on network load balancing and Microsoft high availability technologies. See PI AF high-availability solutions.
-
Install Microsoft SQL Server for your PI AF SQL database in an Always On Availability group. See PI AF high-availability solutions.
-
Install PI Analysis Service in a failover cluster.
-
Install PI Notifications Service in a failover cluster.
We recommend deploying PI AF servers and Microsoft SQL Servers on separate, redundant computers to achieve the best level of performance and scalability.
