NetFlow statistics generate a high volume of data. We recommend that you have the database on a separate server from the Orion server.
We also recommend:
High Speed Disks: 10,000 rpm, RAID 10. RAID controller should have at least 256MB of battery backed-up write-back cache
Regarding the storage requirements, one thing to keep in mind is that we progressively compress data as it gets older, so the storage requirements for 2 days is not twice that of the first day.
That said, for 15 NetFlow nodes, you may need around 15+ GB of storage. NetFlow is inherently storage intensive. That sizing is just a guess because I don't know how much data is flowing through your interfaces. This is also a new product, so we'll get a better idea of size recommendations once it's been out a while. I hope this helps.
Sr. Product Manager, Orion
Thank you very much. Now I will plan for my new test server and I will ask for the temp key again.
