As I wrote a while ago when you enable virtualized MMU for your virtual machine it enables Large Pages and Large Pages don’t get “TPS’ed”. The article I wrote was specifically related to AMD cause it was the only platform at the moment for which enhanced memory techniques where used. (AMD RVI!) As of vSphere 4.0 Intel EPT is also [...]
One of my customers recently asked if it was possible to change the time-out for a power state change, at the same time this question was asked and answered on an internal mailing list. I thought it would be nice to document it. An example of a power state change task would be the shutdown that is initiated by SRM [...]
VMware just released a bunch of patches for ESX 3.5 and 3.0.x. Those of you who did not yet upgrade to vSphere 4 might want to look in to these new patches as they contain security and critical updates.

There are a whole bunch of enhancements which definitely make this new release worth checking out. I’m not going to post them, just read the release notes. Another thing I wanted to let you [...]

If I would ask you what the max amount of VMs per Host is for vSphere what would your answer be?

But is this actually the correct answer? No [...]
As of VMware vCenter 2.5 Update 2 the HA default isolation response changed from “Power Off” to “Leave powered on”. A lot of people liked this new default setting because it would lower the chances of downtime due to a “false positive”. I’ve never been a fan though, I just don’t like using degraded hardware or a degraded ESX host [...]
