The n2k ToR is not a great design for user or storage interfaces if most of your traffic is east/west.  It is great as a low cost ilo/drac/choose your oob port, or if most of your traffic is north/south.  Biggest thing to remember is that it is not a switch, and has limitations such as not connecting other switches to it. Like anything else you have to understand the product so that you don't engineer something that it wasn't designed to do. 

Lots of very large companies using Nexus gear...

That being said I prefer Arista when I'm architecting DCs.

More specifically I am interested in hearing about FEX with N2K at the ToR and if this has indeed made any impact on Opex as well as non-obvious shortcomings to using the fabric extenders. Also if anyone is using any of the Nexus line for I/O convergence (FCoE) I would be interested in hearing your experience with this as well.
