Hi Kshitij,

The 2148 FEX is not supported for UCSM C-Series integration instead, you would need to get a 2232.  If  don’t want to get new FEXes (2232) you will need to upgrade your UCS environment to the 2.2 firmware release where Direct attach is now supported see below. Note that not all the C-series servers are supported on this mode, so please read the documentation below.  This documented also have the best practice when integration c-series servers with UCSM.  Finally, once you have these servers integrated with UCS you will be able to assign service profiles like the B-series servers and assign boot policies that uses your SAN (boot from SAN).

Kshitij,

Yes, you can connect your N2k to the N5K if you need extra ports.

See the documentation below for connectivity solutions with the UCS and Nexus 5K

If you need best practices documents to connect from the N5K to the storage (EMC), I recommend that you contact EMC for their recommendations.
