RSS feed for VMware release notes

by // 9 Comments

Staying up to date with the latest VMware product releases can be a challenge and with something like VMware Cloud on AWS, which is delivered as a service, it can be even more tricky as new updates are constantly being made available. Historically, there has not been a consistent method for how customers can get notified of new releases and this has also come up from our VMware Cloud on AWS customers.

We posed the challenge to our Information Exchange (documentation) team to see how we can help our VMware Cloud on AWS customers and the team came back with an initial implementation of providing a standard RSS feed which you can now find at the upper right hand corner of the VMware Cloud on AWS release notes page. You can subscribe using your favorite RSS reader, I personally use Feedly and when a new release of the SDDC and/or service, you will get notified via your RSS reader. For those that want a different delivery mechanism such as email for example, you can use the free If This, Than That (IFTTT) service which I also personally use and setup an email notification or any other type of notification that IFTTT supports.


Although this initial requirement was driven by the VMware Cloud on AWS product team, we definitely wanted to see this capability delivered across all VMware products and services which is what the team has done as well. When you navigate to a specific product and/or service release notes, you will now see the additional RSS feed that you can subscribe to.

Here are just a few of the popular RSS feeds that I know folks will want to subscribe to. For a complete list of all VMware product/services, please take a look here.

I think this be a great first step in helping our customers easily get notified of new releases, so that can start reviewing the release notes and start planning. I know many of you have also asked for other methods such as programmatic access to release notes updates or even having a specific changelog for things like our APIs. If folks have any feedback in this area, feel free to leave a comment and I will be more than happy to share this with our documentation team.

Configure NSX-T Enhanced Data path / Network Stack (ENS) for Nested ESXi

by // Leave a Comment

After publishing my Running Nested ESXi, NSX-V or NSX-T on top of NSX-T article which actually turned out to be quite popular, I received an interesting question on whether ENS for NSX-T could also be configured within a Nested ESXi deployment? I was a little familiar with ENS, which I will explain in a second. However, I was not completely sure about the benefits of running ENS in a Nested environment.

With the help from my friend Frank Escaros-Buechsel, who actually works in our NFV group at VMware. Frank helped validate the instructions but he also provided some additional insights on why this could be useful in a lab setup for verifying configuration and behaviors when additional tuning maybe required. If you are NOT running NFV-based workloads, ENS is not something you need to configure when running NSX-T using Nested ESXi.

So what is ENS?  Enhanced Network Stack (ENS) also referred to as Enhanced Data Path is an NSX-T capability which was first introduced with NSX-T 2.3. ENS is specifically designed for Network Function Virtualization (NFV) workloads that require a high performance data path. Such workloads include Telco, 5G and IoT based deployments where improved packet throughput is critical for the responsiveness of these applications.

Running Nested ESXi, NSX-V or NSX-T on top of NSX-T

by // 6 Comments

Nested Virtualization is an extremely useful tool that helps customers easily test and try out new VMware products and solutions before rolling that into a proper development environment for further validation. This is especially handy for those wanting to setup an NSX-based environment and simulating their actual deployment topology, configuration and upgrade workflows.

In this past year, I have seen a 10x increase in the number of NSX-T based questions that have come up from customers and our field, the adoption of NSX-T is definitely in full swing. As expected, questions about running Nested ESXi on top of a physical NSX-T deployment has come up and there has actually been several variations that have been asked about whether that is Nested ESXi using VSS, VDS, NSX-V or even NSX-T running on top of an N-VDS, which is the virtual switch that NSX-T uses.

Luckily all of these combinations work and just require some basic configuration changes within NSX-T. However, before I continue, let me remind folks again that VMware does NOT officially support Nested Virtualization.
