The Nexus 2000 is now orderable so Cisco DC vision is just about complete. When the Nexus 1000v is final than Cisco's vision for the data center will be a full leap ahead of everyone else in the industry. They will have a full product line that can bridge the gap between today's data center needs and support what your data center will look like for several years to come.
The remarkable thing is that Cisco pulled this off in 1 yr. The release of the Nexus 7000 was just over 1 yr ago and while definately early out of the gate it is remarkable the amount of engineering and resources that have gone into building out this new data center vision. Cisco is back in their element - everyone else better look out because the 800 gorrilla is on a rampage!
