vmware essentials plus license

Hi Experts,

it is just a short question about essentials plus license.

I have just 3 hosts with esxi.
I know I can license 3 esxi hosts with this license right ?
Now we want to use windows 2012 for our vm´s
I have seen a win2012 datacenter license is for 1 physical maschine or for unlimited vm´s, right ?
Do I have to buy 3 datacenter licenses because of my 3 hosts ?

Yes you need to purchase 3 Windows 2012 datacenter licenses per processor in the Host and then you have Unlimited VMs per Host.

Cliff GaliherCommented:
Per two processors technically. But yes, the unlimited VMs granted by datacenter are limited to a single physical machine.

Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

So you will need 2 x Licenses PER HOST.

So in TOTAL you will need 6 Microsoft Windows 2012 Datacenter Licenses.

Understand ?

but they write this:

A Datacenter edition license will entitle you to run an unlimited number of VMs on up to two processors.

I disagree. 3 licenses would cover it. Again, a license covers TWO processors. As per question 9 in the document Hancocka  linked to.

...and read this
Each license covers up to two physical processors, so to determine the number of licenses needed to fully license a physical server, simply count the number of physical processors in the server, divide that number by two and that tells you the number of licenses that will be needed.

correct in question 9 it is clear.

so, in vmware I have to calculate with each host, because the vm's can run on each host because of HA or migrate a vm, right ?

Cliff GaliherCommented:
You always have to calculate per physical server. Not because of VMWare, but because that is the licensing model Microsoft chose. You'd have to do the same for virtualbox, hyper-v, or others as well.

Microsoft has nothing really to do with VMware
