How does the licensing model of Windows Server Data Center Edition work?

According to this Microsoft page a copy of Windows Server DCE is $4,809 and as far as I can tell I can run as many Windows virtual machines on top of this. I have been reading through the site and I am completely confused;

  • Is this any version of Windows, so I could spin up 50 Windows 7 virtuals, or is it DCE only?

  • There is usually a limitation somewhere but I can't find it; I am suspecting there is a limit on the number of CPUs per physical server or the number of cores per CPU. Is this true here?

Thank you.

Windows Server 2012 Datacenter Edition is licensed per-socket. A single DCE 2012 license is good for 2 sockets and will entitle you to run as many VMs of any Windows Server OS on a single piece of physical hardware that has all of the physical sockets licensed.

You don't even have to run them on a DCE host. You can even have 50 Windows VMs on a VMWare ESXi host as long as you have DCE licenses that cover all physical CPUs in that ESXi host.


Of course, like all licensing questions on this site - you're best off contacting a reseller that specialized in licensing. After all, we're sysadmins, not VARs and licensing partners.

@TomTom Can you explain what is wrong about the last sentence please? :) –  jwbensley Nov 1 '12 at 14:23
    
@javano He was saying that he's a VAR/licensing partner. Generally we don't deal with licensing questions here. He was just making a joke - the information pertaining to the actual answer is accurate. –  MDMarra Nov 1 '12 at 14:24
    
@MDMarra Ah!I thought he meant the last line of actual content, above the horizontal rule :) –  jwbensley Nov 1 '12 at 14:28
