Hi all
I know there are 1000+ threads with questions about TMG licensing and virtualization but I haven't found the answer yet. I'm really confused and maybe someone can help me.
We have a Host-System with two 6Core CPU. We plan to assign 8 vCPUs to the VM.
We want to buy a TMG Enterprise License (not much time left to do that ;-))
At a TMG course we were told that with the TMG Enterprise License, we just need 1 license per physical processor available and not for every vCPU we assign to the VM.
According to many threads I found, this must be wrong. And I also found the following official document:
http://download.microsoft.com/download/B/D/3/BD3C5A07-599D-4C14-AC2E-A98F495CCFB5/Forefront%20Licensing%20Datasheet.pdf
"Forefront Threat Management Gateway 2010 is licensed under the processor licensing model, with a license required foreach physical or virtual processor accessed by an operating system environment (OSE) running a Threat Management Gateway server."
So with this statement we would need 8 TMG Enterprise licenses if the VM has 8 vCPU.
But I also found opposite statements like in this document:
http://logiciels.univ-rennes1.fr/html/intranetur1/editeurs/microsoft/Docs/TMG_PL_guide_v2FINAL%20101909.pdf
"With TMG Enterprise Edition, customers need to licenseonly the physical processors and can run the software on anunlimited number of virtual CPUs"
With this statement we would need only 2 TMG Enterprise licenses if the Host-System has 2 6-Core CPU.
(although the document looks official, I couldn't find this document on microsoft.com so it might be outdated and the statement isn't valid anymore?)
And also on this page:
http://microsoftguru.com.au/2011/01/12/forefront-tmg-2010-frequently-asked-questions-faq/
"Support for unlimited virtual CPUs -> yes"
Can please someone clarify if I need 8 or 2 TMG Enterprise licenses?
Is the second document I linked not valid anymore?
Thanks a lot
