Since netflow processing is generally I/O bound, you may want to invest in 15K drives.
I had suggested off-list that perhaps primary storage as SSD was a better path, is there a reason to not do that? (with some larger storage on spinning-media for historical storage/query).
Nope, great suggestion. Just a cost consideration ...
ah, ok... I figure that even if you were to put in 2 || 3 SSD drives in the 200gb range, one per controller, you'd get maximum throughput for a few days of data at not very much of a premium, then back up / near-line store the data longer term on spinning 2tb or so disks.
