Suggestion on Switch Hardware and Model

[netbeginner]

Hello All, 

We have to suggest a Nexus Switch with Low Commercial which having at least 16 X 10 Gig speed optical Ports ,  should support port-channel , should support port SPANNING and obviously vPC.

Deployment plan is : 02 Switches per DC (we have 02 DC in our scneario).

pls recommend some good Nexus Models along with license requirement as per above mentioned feature. Key point in Low Commercial.
