I am designing a new model and am really grappling with the fiber uplink speeds. I am trying to build a network resilent enough to support data for the next ten years. I am trying to decide if I need a 10 gig fiber uplink to my data center on the third floor of the building from each of the adjacent floors. I am planning on running a 48 port gigabit switch on each floor, and at the moment without VOIP. But I'm trying to peer into my crystal ball for years down the road to see what my requirements will be. Currently we are a 10/100 based LAN with all the normal windows domain things, file shares, exchange, internet, etc. I could also concatenante some 1 gig fiber links, say 4 per floor, to get to almost half the bandwidth but with multiple fiber strands.
Either way I was just hoping for some feedback. There are advantages to each, I'm just worried as my switches begin to max out the ports, and the computers and network start utilizing the gigabit bandwidth more that my uplinks will begin to be the bottleneck, not today or tomorow, but a few years down the road. Am I crazy? Any help would be greatly appreciated, or a link to a thread that has already addressed this issue.
