There are a few NSX Communications network diagrams floating around, but none have really displayed the info in a way I found to be clear or complete enough. To that end, I have been working on a diagram that covers as much of the communications between NSX Components as I can. I’ve currently only covered single site NSX (not Cross vCenter) but I’ll publish an updated version soon including that.

vRealize Automation and NSX integration has introduced the ability to deploy multi-tiered applications with network services included. The current integration also enables a method to deploy micro-segmentation out of the box, based on dynamic Security Group membership and the Service Composer. This method does have some limitations, and can be inflexible for the on-going management of deployed applications. It requires in-depth knowledge and understanding of NSX and the Distributed Firewall, as well as access to the Networking and Security manager that is hosted by vCenter Server.

Yesterday saw the release of NSX-T 2.1, with some new features and also some usability enhancements. You can check out the release notes here https://docs.vmware.com/en/VMware-NSX-T/2.1/rn/VMware-NSX-T-21-Release-Notes.html As I’m mid-way through this blog series, I thought I’d stick in the upgrade as a little bonus! Download the upgrade bundle Validate the version and status of NSX-T components Check the Controller cluster status and Manager connections are up. Validate the hosts are installed, and have a connection to the controller and manager.

Disclaimer! I am learning NSX-T, part of my learning is to deploy in my lab - if I contradict the official docs then go with the docs! Lab Environment This NSX-T lab environment is built as a nested lab on my physical hosts. There are four physical ESXi hosts, onto which I will deploy three ESXi VMs, a vCenter Server Appliance, NSX Manager, an NSX Controller cluster, and two NSX Edge Nodes.

A little while ago I replaced my three ageing Intel NUC hosts with a single (still ageing) Dell T7500 workstation. The workstation provides 24 processor cores and 96GB RAM for a really reasonable price, while still being quiet enough to sit in my home office. One of the driving factors in retiring the old NUCs was vSAN - I know in the newer generations of NUC you can get an M2 and a SATA SSD in, but my 1st gen.

Last Tuesday I had the privilege of presenting an introduction to the NSX APIs on vBrownBag EMEA - you can view the recording below or on vBrownBag’s youtube channel. During the presentation I showed a mind map of the API, which I’ve made available on GitHub in PDF format I’ve also published the Postman collection and environment I used during the demonstration, which covers some basic configuration and deploy tasks:
