Hi, great post.

It was very helpful information to be aware of how SCVMM make this calculate.

Let me one ask about that. Do you know how calculate overcommited under the Dynamin Memory enoviroment (Windows Server 2008 R2 SP1)? because it´s dynamic memory and SCVMM need to calculate slot size with a largest VM, which will be slot size? Will be dynamic??

Thanks in advanced.

Regards

IMO - the way MS determines over-provisioning is flawed. I've been forced to set my cluster host failure threshold to 0 becaue of it.

I have 4, 100% identical nodes in my cluster. I always keep 1 node free from any Virtual machines (Yes - 0 VM's). Yet, SCVMM states the cluster is oversubscribed.

This is obviously a design flaw that needs to get fixed if MS thinks they are going to continue to compete against VMware.
