vSphere 5.5 – ESXi minimum RAM

With vSphere 5.5 about to go GA, something that people may not know is that there’s an uplift in the host minimum memory requirement. I noticed early in the beta process that if I configured a host with only 2GB of RAM (the previous maximum) while it would install and run fine, as soon as I joined it to a cluster the host would PSOD. I soon learned that the memory footprint of ESXi has increased by a little bit, as soon as the FDM service was started, it would tip over the edge.

So, with that in mind I had to increase my nested hosts to 3GB to get them to run properly… when you add in VSAN and any other services needed, you may find that even that is not enough. ESXi 5.5 “officially” requires a minimum of 4GB of RAM.

Time to upgrade those lab hosts! 

Announcing Mastering VMware vSphere 5.5

After months of learning, writing and endless lab rebuilds I am very excited to announce the project I have been working on:

Mastering VMware vSphere 5.5

When Scott Lowe first approached me in late 2012 about a possible writing opportunity I couldn’t begin to understand what the next 9 months would entail. The project has certainly been mammoth, but one that I’ve thoroughly enjoyed along the way. And the best bit is yet to come, I get to share it with the rest of the VMware community!

This new revision has been revised for the newly announced vSphere 5.5 and covers all the features introduced in both 5.1 and 5.5. Getting up to speed with the vSphere Web Client has never been easier, as every example both new and old has been written with the Web Client in mind. At a high level, some the new coverage includes:

  • Single Sign-On
  • VSAN
  • vFlash
  • LACP
  • vC Ops

As Scott mentioned when he announced the 5.0 edition “This book won’t go as deep as some other books on the market, but that’s not really its purpose.” – and the same goes for this edition. The idea is real world, practical information to help you get the most out of vSphere 5.5.

I would like to put a big thank you out there to the contributing authors, Forbes Guthrie, Matt Liebowitz and Josh Atwell. These guys each submitted a quality chapter towards this book and I am ever grateful for their contributions. And of course, thank you to Scott for this opportunity. I hope that I have lived up to your expectations with this work and you have no regrets handing “your baby” over to my care. I certainly will pay it forward when the time is right as you so graciously did for me.

So, I guess the question is, when is it available? It’s available for pre-order right now from Amazon, and should be generally available late October / early November.
