Host requirements for virtualization with Hyper-V

Question

I’m planning to create a virtualized setup for a company I work for and I’ve been looking at server configurations. I’ve settled on a Dell PowerEdge R710, but I’m not sure which OS is right for me. My choices are between 2008 R2 EE (~$9,800) and 2008 R2 DC (~$12,800).

I have a friend who’se already done a similar setup for his work place and they’re running 2008 R2 DC and he believes that if you’re on DC then you have an ‘unlimited guest os’ license where as EE is limited to 4 (according to him). Is that true, and would it be beneficial to go with DC for an extra $3,000?

Also, if you go with DC, does that give you access to some super MSDN or TechNet account that allows you to download OSes for VMs as needed? Or if not, I’m assuming I just buy a product key as needed to deploy a new VM?

Thanks in advance for any help!

Answer

As I recall, the retail license for Windows Server 2008 R2 EE comes with four VM licenses. That doesn’t mean you can’t create more than four VMs, but it does mean that you will need to purchase licenses for the number you create beyond four. You could purchase a license for each VM beyond four, but as explained in this blog on Microsoft TechNet

You can assign two EE licenes to the host to obtain 8 VM licenses, or three EE licenses to get 12 VMs. It all comes down to how many VMs you need as to which OS you need to purchase. And don’t forget to purchase lots of RAM in your server. Hyper-V loves RAM.
