Maybe I am missing the point here, but each of my devices will be monitored on its primary IP/interface. >> I am figuring that we will want to run OpenNMS, Postgres, and Tomcat all >> on the same server. > > You'll have much better performance if you can arrange to store the > postgres DB, logs, and jrbs on different physical disks to avoid the > head contention when these are all written in different places at the > same time.

However, have things changed a lot in the last 4 or 5 years? Back maybe 5 years ago, we had a simple, 2U, RedHat linux server with two hard drives (mirrored) running OpenNMS, PostgreSQL, Tomcat, etc just fine. We are finally ready to stop using Sitescope and go back to OpenNMS but now I am getting concerned about the hardware requirements. Am I dreaming to think I can ping monitor and do SNMP polling on about 200 different devices/IPs from a single server with two hard drives? On most of these devices, we will probably just send SNMP Traps to OpenNMS and no SNMP polling. (If there is a lot of log data, I can probably store it on our file server/NAS.
