I am moving my company to a new building. We are leaving all the old network equipment behind and building out a new network. My question is what is the advantages/disadvantages to using stackables in the core versus a 6500? I only need about 6-10 10GB uplinks to the closets and maybe 40-60 ports in the core for servers, etc. I wont need PoE in the core, and will have seperate routers, firewalls, and APs, so I wont need to put those into a chassis. It seems cheaper and simpler to just have 3750E for all my LAN switches. i can have one or 2 on the shelf for replacement and save more on maintenance. Am I missing something by not going for the 6500's?
