Frank, I posted this to Duncan as well to see if any of you can help me!

With DRS turned off, and thus, no affinity rules, is there any way to know (or to control) which host will be my rescued VMs transferred to in case one host fails?? I need to make sure 2 VMs won’t be on the same host in case one of the host fails! I must keep them on separate hosts. Is this possible??

thank you very much!!

Beside Oracle, any other ISV that is charging for the _entire_ cluster?

I wonder if any legal department in large enterprise has reviewed Oracle licensing policy. IANAL, but it looks grey to me when it comes to this new affinity rule.

Separately, what if DRS is disable at the cluster level. So it’s just a simple HA. Does Oracle still charge for entire cluster, so it’s down to 1 host?

Thanks from Singapore.

Great post Frank, very informative. Out of curiosity, how long does it take DRS start to apply the prerferential rule after an HA event such as host failure has occurred?

Its a great feature. VMware have really upped there game with 4.1.
