Last week I had the opportunity to join John Troyer on the VMware Communities podcast. My purpose, as John put it when he invited me, was to “gently introduce” the community to the idea of network virtualization, which is where I now spend most of my time since joining VMware in early February. Or virtualized firewalls?

VMware equates network virtualization to Server Virtualization. I re-read the VMware post announcing the NSX product and it all kind of just clicked for me. Source VMware. These virtual ports can then be assigned to a virtualized Firewall, Switch, Router or IDS ports based on the need. Related Posts.

Although I used to work at EMC before I joined VMware earlier this year , I never really had deep access to what was going on with this project, so my thoughts here are strictly based on what’s been publicly disclosed. Naturally, given that the product was only announced today, these are very early thoughts. .”

A discussion of “statefulness” brought me again to Ivan’s post on the spectrum of firewall statefulness. VMware introduced VMware NSX recently at VMworld 2013. I found a few articles by fellow VCDX Josh Odgers that discuss the impact of Nutanix’s converged architecture on vSphere designs.

Using 1 GbE would have required too many ports, too many cables, and too many switches; 10 GbE offered Expedient a 23% reduction in cables and ports, a 14% reduction in infrastructure costs, and offered a significant bandwidth improvement (compared to the previous 1 GbE architecture). Note that there are trade-offs as a result.)
