I wasn't the implementing engineer but I've been at two places that did that, a larger game company and a network gear manufacturer in their engineering support computational hubs. I was there during planning and rollout at the game company, very early in the Nexus lifespan. Both sites brought the FEXes back to 5500s; one used a 6-something for core, the other a pair of 7ks. Game company was more east-west, telco eqpt was very heavy east west. In both cases it's working fine. George William Herbert Sent from my iPhone

Nanog,
I would like to poll the collective for experiences both positive and negative with the Nexus line. 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.
Thank you in advance,
