Last week VMware officially released an official paper around Deployment Best Practices for HA. I was one of the authors of the document. Together with several people from the Technical Marketing Team we gathered all best practices that we could find, validated and simplified them to make it rock solid. I think it is a good read. It is short [...]
In August we announced that we were working a secret project and let you guys in on it. The idea was to get it published through an official Publisher but due to several circumstances and a very tight deadline we decided to go the self-publishing route to make it available as soon as possible.

I downloaded Symantec’s Application HA and decided to give it a spin, I already started documenting the installation of the ApplicationHA Console and the Guest Component but Mr Sloof beat me to it and documented his finding in the following two articles.

Although at first it might not seem substantial it actually is. As of vSphere 4.0 VMware [...]
A week ago I already touched on this topic but I wanted to get a better understand for myself what could go wrong in these situations and how vSphere 4.1 solves this issue. Pre-vSphere 4.1 an issue could arise when shares had been set custom on a virtual machine. When HA fails over a virtual machine it will power-on the [...]
