If you had to write a reference architecture document where you had to delineate the architectural and operational requirements for a user access switch and a server farm access switch, what would be the main differences?
The way I look at it, for any environemnt where I had more than 200 connections in a mission critical office, I would not use the 3750 stacks. I would go for a chassis-based switch with dual SUPs and redundant power supplies.
I would go for a dual 4507 switches for the user access layer.
But what about the server farm? I think I would need something more robust, like a 6509 (same architecture though -- dual SUPs, dual power supplies, chassis based, etc).
