You should connect 6248 to Nexus 7000.

Nexus 2000 was created to connect end-hosts and not switches or FI. Since all local switching is performed on N7k, if you connect FI to N2k, traffic even between blades will be send through n2k to N7k,  fabric link from N2k to N7K will be oversubscribed and UCS will suffer from low performance.

So FI should be connected to N7K

If you would have 10G 2Ks, it might make sense to do it. You would trade throughput for cabling convenience.

In you case you can use 2000 ports for UCS management.

Is it really possible (and supported) to connect UCS FI uplinks to Nexus 2000???

Yes.  Why wouldn't it be?  A Nexus 2000 is just an extension of a Nexus 5000/7000.

UCS is an end host device by definition.

Great. Thanks Robert
