Today Rob de Veij released an update of his excellent tool called RVTools. We are up to version 3.2 already. You can find the update on the RVTools website. RVTools is an essential tool for every vSphere Admin. It allows you to report on the most important aspects of your virtual infrastructure, but probably the most important ones are limits [...]
I had this post sitting in my “Draft” box for a week and didn’t notice it never got published. Although a bit late here it is. At VMworld Copenhagen I tried to spot a whole bunch of rockstar Bloggers / Tweeps. I tweeted their pics during the show but I figured not everyone of you is online all of the [...]
I was listening to some VMworld talks during the weekend and something caught my attention which I hadn’t realized before. The talk I was listening to was VSP2122″VMware vMotion in vSphere 5.0, Architecture and Performance”.

After diving in to the problem it appeared that both HA and DRS were still working. It seems that some how the vSphere Client thinks it is [...]
I was reading a whitepaper by VKernel and it mentioned the following “a failover host for these VMs requires sufficient idle resources“. In this whitepaper it is discussed how Monster VMs pose challenges for both HA and DRS. As I had a similar question last week at VMworld I figured I would post this. Also because it is fundamental to [...]
I was asked to speak at VMworld Europe in Copenhagen and before I flew out I planned on writing daily wrap-ups again. It usually helps me to wind down, but this time I never really got around to it. I figured I would at least write this article at the end of the week to summarize some of my personal [...]
