We are implementing a core and failover unit at our aggregation point which will only receive information from remote probes out in our school districts. Each school will have a single NetFlow sensor and anywhere from 50 to 2500 sensors (mainly on the smaller end) being monitored by their probe.
Question#1: How many sensors would our core be limited to for this scenario?
Question#2: When purchasing hardware for our core server(s), should we lean towards more RAM or more processing power or a balance of both?
Question#3: Is there any advantage for performance with any specific RAID level on the core server?
