Windows Server Licensing and vMotion
Morning all :)
I was wondering if any of you might be able to help me find the answer to this question (I don't fancy trying to find out from Microsoft as they just pass you between departments!). We have a VMware virtualised platform, 3 hosts and a SAN.
What is causing confusion is whether or not we need a Windows Server license for each host that the VM could run on.
For example... we have 3 hosts and 6 VM's. Do we need...
- 3 licenses for Windows Server 2008 R2 Standard (Standard licenses license you to run 2 VM's on one physical box).
- 18 licenses for Windows Server 2008 R2 Standard to allow any/all of the machines to be run on any 3 of the hosts at any one time.
- 6 licenses for Windows Server 2008 R2 Datacenter and be done with it (2 processors per host)?
Thanks in advance!
