Session Abstract
The session will start with an overview of the Nexus 9000,7000 switches
followed by the latest updates to Nexus 2000 thru Nexus 6000 Switches
portfolio and will also include recent key NX-OS innovations
This session will help audience understand how the Cisco Nexus switches
series switches can help build highly dense & scalable 40/100G fabrics in
there Data Center networks. It will also cover some high level design options
using the portfolio above.
