Virtualisation Podcasts – Keeping your finger on the Pulse

For many years I’ve found listening to Podcasts a great way to keep up-to-date with Virtualisation and Technology.

It all started with the VMware Communities Roundtable podcast, where I quickly realised the commute to work didn’t have to be “dead time”.

Here’s my current list of Virtualisation and Tech podcasts:

  1. Packet Pushers Datanauts
  2. Speaking in Tech
  3. In Tech We Trust Podcast
  4. The Cloudcast (.net) – Weekly Cloud Computing Podcast
  5. The Full Stack Journey
  6. Virtually Speaking Podcast
  7. The Geek Whisperers
  8. VMware Communities Roundtable
  9. Cloud Insiders
  10. vChat (MP3 VERSION) – The Latest in Virtualization and Cloud Computing
  11. The Data Center Insiders Podcast: Virtualization | Cloud Computing | Enterprise IT | VMware | EMC

The best Podcast app I’ve found to date is Overcast, as it has very useful features including Voice Boost and Smart Speed, Playlists, and a great UI.
Oh yeah, and it’s free!

I’ve you want to quickly import the above podcasts, download and import my OPML file here: overcast-adam-rush

Find Upgradeable vShield Edges

I was recently asked if there was a quick way to find out how many vShield Edges were out-of-date and could be upgraded in a vCloud Director environment. I didn’t know of any, so I turned to my good friend PowerCLI and came up with this:

This script does assume that at least one of the vShield Edges in your environment is up-to-date, as it looks for the highest available version deployed and not the known latest version.

VMware Training Resources

I regularly get asked where good VMware training resources are found for various VMware products, so I thought I’d better create a page I can add links to as find them.

vCloud Director

Since I’ve had a focus on vCloud Director for the past few years, these links are fresh in my mind:

  1. VMware has recently updated their Fundamentals course, so this is probably the best place to start: VMware vCloud Director Fundamentals 2016

vCloud Networking

  1. Networking is often a tricky area for new users of vCloud Director, so here is a the best presentation I’ve found so far that explains how the different networking components fit together:

vCloud Design

  1. vCloud Director Design and Scale:

I’ve just found this page which includes most of the above links and more:

I’m a big fan of Pluralsight and can highly recommend these courses:

Free iSCSI SAN for your home lab using FreeNAS 8.2


You have a home lab set up so you can experiment with the latest and greatest software and technology. You could be using VMware ESXi, Hyper-V or another hypervisor for your lab, but they don’t come with shared storage built-in. You need shared storage to set up features like Failover Clustering.

Luckily, you don’t have to spend a fortune to get an iSCSI SAN for your home lab. As the name suggests, FreeNAS is FREE!

Read on to learn how to install FreeNAS 8.2. I’ll be using VMware Workstation, but the process is similar for most hypervisors.
