So here is my question. What do you do with equipment that isn't old but doesn't handle the load you are moving too or the vendor tells you it doesn't carry the load?
I currently have a TZ215W(@HQ) and two TZ-215(@remote sites) and unmanaged switches. I am moving to having the two remote sites on site to site fiber and moving them to all be one network. I have talked to SonicWall and they only suggest 30 devices connected for optimal use. I have around 80 devices total once I combine the networks. My HQ will be the only site with Internet so all traffic will be routing to HQ.
Should I take the hit and purchase a UTM designed for that traffic or should I redesign my setup to use what I have? Ultimately all that traffic will hit the main UTM that I use.
Here is a diagram of current and upcoming overview:
