Re: Sizing for a Small School
It depends on what your doing. For example, I had a similar setup that I did many years ago using comcast business but at 50mbps. It for a private school with a bunch of k5 grade classes. I'm using a pair of FGT60C ( that all they could afford ) and in one case a FGT80CM.
We are doing URL filtering for the most part, no AP, no DMZ hosted devices, etc....
A FGT90D or 100D should fit your needs but how much AP traffic to you see and really how many APs?
note: a FGT90D has more thruput than the 92D and is still cheaper priced, not to sure on cpu/memory requires of the 92D.
if you budget can afford it the FGT100D are great in the low-end spectrum and not a whole lot more. Review the specs and matrix and then go from that point and the needs you forecast now and in the future. Fortinet always stress more than less.
