I am to plan and roll out a fibre network across london for my company. We require fibre router / switch at our at our 2 data centre. These will have lots of space for use to slot in cards for whatever puspose we need, single / mutimode fibre, dark and lit fibre, sonet etc. From out data centre we will have fibre connections to different locations in London.
I have been told the best way to go is the 6500 series since the company is willing to spend some money. Only problem is I am not really sure of what I am buying. The sales guy quoted for the follwoing
WS-C6509-E with fan tray
2 x WS-CAC-3000W PSU
48 Port Gigabit copper
WS-X6748-GE-TX - £1600.00
He also quoted me for 2 kinds of supervisor card the WS-SUP720-3B, and the 4 times more expensive WS-SUP720-3BXL. I am trying to figure out which of these I will need for my purpose? What are the core differences?
