[c-nsp] Nexus 2000 vs Catalyst 4948 for access layer

[Livio Zanol Puppim]

Hi folks,

Can anyone please tell me the advantages of using Nexus 2000 over Catalyst
4948 as access layers switches?
Using Nexus 2000, I have to use at least 2 ports at my Nexus 5000, that
could be used by servers with 10GbE/FCoE servers.

Also, are there any advantages on NX-OS compared to IOS?

Thanks.
