Hi Alexander,

I would say it is a much better architecture for various reasons.

1. With Nexus FEX, the N2K act as line cards & all traffic has to be sent to the parent N5K whereas the QFnodes have a routing engine to decide where to send the packet.
2. There is only a single lookup across the whole system. There is a Fabric Header that is added by the QFnodes to determine which QFnode the packet should be sent to .
3. The system can scale up to 6,144 10GE ports and still managed as a single switch.
4. Fully converged I/O in terms of connecting the SAN switches to the QFnodes.
