When I started out with ESX 3.0.x the first thing I wanted to do was disable the VMFS-2 driver. There’s no need for it when you’re not accessing VMFS-2 volumes and removing it can lead to performance gains or at least a faster rescan of your storage. Removing it, according to to this section of the VMware website, was supposed [...]

Your VMFS has been recognized as a snapshot, what are you going to do? Hopefully most of you have read my previous post on this topic by now. If you didn’t, be very ashamed and start reading my EnableResignature post before you continue. I was just playing with a VMworld Europe lab manual, which was about the next version of [...]

I just received an email from my colleague Massimiliano Daneri. He wrote a script that automates the installation of the new performance reporting plugin. Richard Garsthagen already wrote an article including screenshots about the plugin by the way, take a look here: http://www.run-virtual.com/?p=276 Check the following KB articles for more info on the installation of the plugin  and after reading [...]

Back in the days of ESX 2.x there wasn’t such a huge community, but there was one tool that everyone knew about and probably everyone tested and used at one point, vmktree! Lars Trøen is man behind [...]

One of the most promising blogs of this moment is definitely Frank Denneman‘s blog. Frank is a freelance consultant with a focus on virtualization and storage. His latest addition “Increasing the queue depth” is an excellent article and really shows that Frank knows what he’s talking about! When it comes to IO performance in the virtual infrastructure one of the [...]
