Today Cisco released two videos on the Cisco Nexus 1000v, going into a lot of good deals about how it works. I’d recommend anyone considering the Enterprise Plus edition of VMware vSphere and the Cisco 1000v to look at the videos.
If you want to view them in HD, so you can clearly see the screenshots, take a look at their facebook page. Look on the LEFT side of the page for the two videos with the HD icon. The primary videos in the middle of the page are low-resolution and VERY hard to read.
