The webinar slide deck includes NSX-T details that will be covered in NSX Architecture Deep Dive workshop in early September 2019, and in live webinar sessions starting in mid-November 2019.

If you cannot attend the September workshop and need more details before November, please contact us.

2:09:45 Introduction and Overview

This section is answering the fundamental questions one should know when considering VMware NSX:

  • What problem is it trying to solve?
  • What are the differences between NSX-V and NSX-T, and where would you use one or the other?
  • How is the product licensed?

It also describes the high-level architecture of NSX-V, its components and their interaction.

1:12:24 Logical Switches in NSX-V

VMware NSX logical switches implement overlay virtual networks emulating Ethernet (layer-2) segments with VXLAN encapsulation.

This section describes how NSX implements VXLAN data and control plane, and what it expects from the physical (underlay) network infrastructure.

1:05:54 Gateways to Physical World

Overlay virtual networks are more scalable than traditional VLAN-based virtual networks... but the clients accessing the servers connected to the overlay networks still reside in the physical world.

This section describes three variants of physical-to-virtual gateways (bridge, router, network services device) and their software and hardware implementation in VMWare NSX-V.

37:14 Distributed Logical Routers

Distributed logical routers provide optimal any-to-any packet forwarding within overlay virtual networks. This section describes the details of NSX-V distributed logical routers, including:

  • DLR control- and data plane architecture;
  • Packet forwarding with DLR;
  • DLR integration with the outside world.

29:24 Firewalling and Security

VMware NSX-V includes stateful distributed firewall that can filter traffic not only based on traditional attributes (IP, MAC, TCP/UDP ports) but also based on vCenter objects, users logged into virtual machines, or application fingerprints.

Other security solutions available in NSX-V framework include integratino of third-party security appliances, guest introspection and service composer.

35:39 ESG Network Services

Edge Services Gateway (ESG) provides a plethora of network services including:

  • Firewalling and NAT
  • Load balancing and SSL proxy functionality
  • SSL VPN, IPsec VPN and L2VPN
  • DHCP and DNS proxy

23:03 Cross-vCenter and Cross-Site NSX-V Deployments

Even though NSX-V was never designed for cross-site deployments, VMware force-fit it into stretched VLAN segments concept.

In this section you'll discover the architecture of cross-site NSX deployments, universal objects, routing hacks needed to prevent traffic trombones, and NSX-V behavior under split-brain scenarios.
