You mean internal failover (dual sup) or failover between two Nexus 7K's?

What exactly are you looking for about failover?

I can actually use articles on either subject but predominately articles focused on the failover and robustness features built of the individual box.

Well, I can tell you the supervisor failover is pretty much instantaneous. I can't recall ever seeing a dropped frame. As for non-Cisco articles, the only thing I could think of is google.

With respect to chassis failover, that would be protocol dependent since the protocol (OSPF, EIGRP, STP, etc.) is responsible for detecting a lost neighbor.  The exception to that would be vPC. And unlike supervisor failover, I have seen a packet drop in that situation.
