I just finished overhauling the vSphere HA Deepdive page. It now includes details about all versions of HA but is specifically split up in two sections: 4.1 and prior 5.0 I also cleaned up all comments. Although there were a lot of useful details in there the amount of comments made it impossible to maintain. With all changes in 5.0 [...]

No it isn’t a late April Fools’ joke… And we never expected this to actually happen to be honest. Last week I had discussion about the ebook on twitter and people were convinced that ebooks are the way to go. I won’t deny that and I know Frank agrees with me on this as well but the fact of the [...]

I’ve had this question too many times over the last couple of weeks and instead of answering all of them separately I figured I would dedicate a blog article to it so that I can reference to that.

Yesterday I posted the DRS Deepdive. One of the questions still left open was how DRS decides which VM to move to create a balance cluster. After a lot of digging for non-NDA info I found this “procedure” in a VMworld presentation(TA16) amongst some other cool info. The following procedure is used to form a set of recommendations to correct [...]

Last week I mentioned which metrics DRS used for load balancing VMs across a cluster. Of course the obvious question was when the DRS Deepdive would be posted. I must admit I’m not an expert on this topic as like most of you I always took for granted that it worked out of the box. I can’t remember that there [...]
