I've recently become the admin for the Orion NPM system at the organization I work for and I am still learning the system. We have a pretty large Orion setup with approximately 13,000 elements. Our current setup is such:
Server 1:
Orion Platform 2015.1.0, SAM 6.2.0, QoE 2.0, NCM 7.3.2, NPM 11.5, NTA 3.11.0, IVIM 2.0.0
Runs web, alerting, and the primary poller (~9,700 elements)
Server 2:
Secondary poller (~3,300 elements)
Server 3:
SQL Cluster node (Windows Failover)
Server 4:
SQL Cluster node (Windows Failover)
Our first poller is getting quite bogged down and Orion is becoming very slow to launch the web front end. I am looking to separate these polling functions from the front end. More specifically, I'd like to build a new server for the front end, and possibly a new one for the alerting. Is there a recommended setup for distributing these services, and if so, can someone point me in the right direction? If not, does anyone have any tips on how it would be best to separate these services?
