Hi,
I appreciate any help about this question. I have a client that want to upgrade from vSphere Enterprise to vSOM Enterprise (with vCenter Operations Manager Standard.. by default). This client has some virtual machines that need application monitoring., and as you know, this is possible witht vFabric Hyperic available in the vCenter Operations Manager suite Enterprise. So the customer is going to buy this two products:
- vSOM Enterprise: vSphere Enterprise + vCenter Operations Management Suite Standard (licensed by CPU) ... for the upgrade. And
- vCenter Operations Management Suite Enterprise (25 OS Instance pack) ... for the virtual machines that need application monitoring.
In the architecture, the question is if they can "mix" this two kind of license models in the same hosts, or if they have to put those virtual machines that need application monitoring in separated hosts? 
Thanks for your help!
