Meet Me at VMware NSX Deep Dive Event in Zurich

When VMware launched the first version of NSX for vSphere more than four years ago, the NSBU team reached out to me and asked me to create a sponsored webinar describing NSX fundamentals, its architecture, and high-level deployment guidelines.

In the meantime we discussed updating the materials, but nothing ever happened. Time to fix that, this time from a vendor-neutral perspective. We’ll start with a day-long event on April 19th 2018 in Zurich, Switzerland.

Video: Create an NSX Logical Switch with PowerNSX

After introducing PowerNSX Anthony Burke illustrated how easy it is to use with a Hello, World equivalent: creating a logical switch (VXLAN segment).

You’ll need at least free ipSpace.net subscription to watch the video.

Want to know more about VMware NSX? We’ll run an NSX-focused event and a NSX Deep Dive workshop in Zurich on April 19th 2018, an overview webinar comparing NSX, ACI and EVPN on March 1st, and a deep dive in VMware NSX architecture later in 2018.

Video: What Is PowerNSX?

One of the beauties of VMware NSX is that it’s fully API-based – you can automate any aspect of it by writing a script (or using any of the network automation tools) that executes a series of well-defined (and well-documented) API calls.

To make that task even easier, VMware released PowerNSX, an open-source library of PowerShell commandlets that abstract the internal details of NSX API and give you an easy-to-use interface (assuming you use PowerShell as your automation tool).

Cisco ACI, VMware NSX and Programmability

One of my readers sent me a lengthy email describing his NSX-versus-ACI views. He started with [slightly reworded]:

What I want to do is to create customer templates to speed up deployment of application environments, as it takes too long at the moment to set up a new application environment.

That’s what we all want. How you get there is the interesting part.

Have to choose between VMware NSX and Cisco ACI? You’re Not Alone

I keep getting questions along the lines of “should I go with VMware NSX or should I deploy Cisco ACI” every single week, and as you know it’s hard to answer anything but it depends without spending hours on the topic.

That’s exactly what we plan to do in Zurich next Tuesday (May 16th) in a DIGS workshop that will run in parallel with the Data Center & Cloud Day (part of the SIGS Technology Conference).

Update: VMware NSX in Redundant L3-only Data Center Fabric

Short update for those that read the original blog post: it turns out that the answer to the question “Is it possible to run VMware NSX on redundantly-connected hosts in a pure L3 data center fabric?” is still NO.

VTEPs from different ESXi hosts can be in different subnets, but while a single ESXi host might have multiple VTEPs, the only supported way to use them is to put them in the same subnet. I removed the original blog post.

A huge thank you to everyone who pushed me with their comments and emails to find the correct answer.

Mini-RSA in Zurich, NSX, ACI, Automation…

I’ll be doing several on-site workshops in the next two months. Here’s a brief summary of where you could meet me in person.

A bit of manual geolocation first: if you’re from Europe, check out the first few entries, if you’re from US, there’s important information for you at the bottom, and if you don’t want to travel Europe or US, there’s an online course starting in September ;)

Can VMware NSX and Cisco ACI Interoperate over VXLAN?

I got a long list of VXLAN-related questions from one of my subscribers. It started with an easy one:

Does Cisco ACI use VXLAN inside the fabric or is something else used instead of VXLAN?

ACI uses VXLAN but not in a way that would be (AFAIK) interoperable with any non-Cisco product. While they do use some proprietary tagging bits, the real challenge is the control plane.

Software-Defined Security and VMware NSX Events

I’m presenting at two Data Center Interest Group Switzerland events organized by Gabi Gerber in Zurich in early June:

  • In the morning of June 7th we’ll talk about software-defined security, data center automation and open networking;
  • In the afternoon of the same day (so you can easily attend both events) we’ll talk about VMware NSX microsegmentation and real-life implementations.

I hope to see you in Zurich in a bit more than a month!

VMware NSX Update on Software Gone Wild

A few months ago VMware launched NSX version 6.2, and I asked my friend Anthony Burke to tell us more about the new features. Not surprisingly, we quickly started talking about troubleshooting, routing problems, and finished with route-health-injection done with a Python script. The end result: Episode 50 of Software Gone Wild. Enjoy!
