We are currently in negotiation to move to a co-location site. I have to purchase new equipment for this site because not everything is going ony mission critical stuff. My question is I have pretty much around 15k to spend on new equipment. I was thinking about just copying what I have here on site which is a few cisco switches. 1 3560G for the routing and 2 2960G's. Would it be cheaper or even smarter to purchase 1 4500 series switch with the same amount of ports? Would there be any benefit from this. I assume it would be more scalable. Also can I purchase a 4500 switch for that amount? Any help is appreciated.
