Using Puppet with Multiple Operating Systems

Over the last few days, I’ve been working with the open source edition of Puppet, the configuration management/automation tool. I’ve learned quite a bit, but I still have a long, long way to go. What I wanted to share in this post is what I learned in using Puppet with clients using different operating systems (OSes). If you are a Puppet expert, I’d love to hear any tips and tricks you might have to help me improve.

vSphere on NFS Design Considerations Presentation

This presentation is one that I gave at the New Mexico, New York City, and Seattle VMUG conferences (this specific deck came from the Seattle conference, as you can tell by the Twitter handle on the first slide). The topic is design considerations for running vSphere on NFS. This isn’t an attempt to bash NFS, but rather to educate users on the things to avoid if you’re going to build a rock-solid NFS infrastructure for your VMware vSphere environment. I hope that someone finds it useful.

Presentation from South Florida VMUG

Back in early March I was invited to speak at the South Florida VMUG, and I gave this presentation on vSphere networking challenges and solutions. The idea behind the presentation was to give attendees some visibility into IEEE and IETF efforts at creating new network technologies and protocols. I’m posting it here just in case someone might find it useful or helpful.

Installing XCP-XAPI on Ubuntu Server 12.04 LTS

As part of my 2012 projects (see here plus an update here), I’ve been familiarizing myself with the Xen hypervisor. To that end, I’ve been working to get XCP (Xen Cloud Platform, the open source version of XenServer) running on a test system in my home office. It’s been a bit of a struggle, but I think I’ve finally got it, and I wanted to share the information here.

Thoughts on a VMworld Unconference

So the “good news/bad news” that is the VMworld submission acceptance/denial notifications happened today. As is typically the case, lots of very talented people submitted proposals for what I’m sure are very informative and useful sessions were turned down. As a result, a lot of ideas were being tossed around about some sort of “unconference” where speakers whose sessions were not accepted could have an opportunity to speak.

Thinking Out Loud: Why Not MPLS-in-IP?

As I was reviewing my list of actions in OmniFocus this morning, I saw an action I’d added a while back to review RFC 4023. RFC 4023 is the RFC that defines MPLS-in-IP and MPLS-in-GRE encapsulations, and was written in 2005. I thought, “Let me just read this real quick.” So I did.

Choosing the Right Tool

Kyle Mestery of Cisco recently shared a link on Twitter about Marco Arment’s choice to move back to a dual Mac setup. The article started me thinking along two parallel lines:

Thoughts on a Couple of Books

I’ve been remiss in posting some thoughts on books that I’ve recently read, so here is an attempt to catch up a little bit on a couple of titles. I don’t know if I would classify these as true reviews, but here are my thoughts and key take-aways from these titles.
