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.)

Instead, Koch’s engineering team set about virtualizing the physical transports to build the SD-LAN and firewall within the cloud rather than in the data center. Co-location providers that offer interconnection-oriented architectures — such as Equinix, Digital Realty, and CoreSite — partner with many of these suppliers.

Anthony Burke (disclaimer: Anthony works for VMware in the NSBU) has a post on how to use Python to automate the bulk creation of firewall rules for use with the VMware NSX distributed firewall. Here’s a post by Grant Orchard on using VMware NSX’s security groups to protect workloads deployed via vCAC (now vRA).

For Carrier Ethernet, Cisco ME3600—a very expensive switch—will allow you to implement such an architecture. VMware NSX has a stateful IPv6 firewall that provides RA guard and ND inspection services. Microsoft also has a stateful IPv6 firewall.). Can we use shared Layer 3 IPv6 subnets?

Examples of hardware virtualization platforms include VMware ESXi and Microsoft Hyper-V Operating system-level virtualization : This type of virtualization allows multiple isolated operating systems to run on a single physical server. The VM is given its own operating system and resources, but they are all contained within the host computer.

Tony Sangha took PowerNSX (a set of PowerShell cmdlets for interacting with NSX) and created a tool to help document the NSX Distributed Firewall configuration. Terraform is used to turn up OpenStack infrastructure, and Skydive (via connections into Neutron and OpenContrail, in this example) is used to validate SDN functionality. What’s that?
