60. Can I buy two HP OEM Windows Server 2008 R2 Standard edition licenses for one physical server, with the

intention of running them each in a virtual machine (non-Microsoft VM)?

Yes. Microsoft licensing (FPP, OEM, and VL) allows this.

Windows Server 2012 Standard Edition

61. Is there any difference in the code between Windows Server 2012 Standard and Datacenter Editions?

No. They are identical. It’s the licensing that’s different.

62. What are the differences in licensing for Windows Server Standard versus Datacenter Edition?

Datacenter has unlimited virtualization and the base license supports up to two CPUs.

The Standard base license has only two VMs and supports up to two CPUs.

63. What’s an additive license?

Microsoft’s new licensing structure allows you to buy just the amount of product you need for the virtual machines

on a server. With the additive license, you can add it to the base license for Windows Server 2012 Standard Edition

to increase to either more than two CPU support and/or more than two VM support.

64. How do I calculate the number of Windows Server 2012 licenses I need for a server solution?

The number of licenses you will need depends on the number of physical processors on the server and the number

of server instances that you will be running. (This only applies for Windows Server Standard Edition because

Datacenter Edition allows for unlimited VMs.) The larger of these two numbers determines the number of total

licenses required. 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 and divide

that number by two. This will tell you the number of licenses that will be needed. For example:

• You have a 2-processor server. 2 physical processors/2 (number of processors covered by a license) equals 1.

You will need one license to cover a 2-processor server.

• You have a 4-processor server. 4 physical processors/2 (number of processors covered by a license) equals 2.

You will need two licenses to cover a 4-processor server.

• You have an 8-processor server. 8 physical processors/2 (number of processors covered by a license) equals 4.

You will need four licenses to cover an 8-processor server.

One single key will be provided and will let you activate the “physical” license and the VMs. You will be able to stack

additive licenses besides the “base license” (which covers two processors) in order to cover the rest of the

processors. As with any HP OEM Windows Server 2012 license, it can only be sold with a new HP ProLiant server.

65. How do I activate an additive license?

There is no product key with additive licenses. Instead, the customer reuses the product key from the base license

to activate the additional operating system environments. Each Windows Server 2012 product key may be used to

automatically activate a limited number of operating system environments. If automatic activation fails, the user is

prompted to phone a Microsoft Activation Center. When they explain to the Activation Center analyst that they are

reusing a base license product key to activate virtual machines covered by additive licenses, the Activation Center

analyst will assist them in activating the VM.

66. Does an OEM license for Windows Server 2012 Standard Edition come with CALs?

No. As of Windows Server 2012, OEM licensing has been aligned to Microsoft volume licensing, in that CALs

are purchased separately. This assures that each customer can purchase only and exactly the number of CALs

they need.

Windows Server 2012 Datacenter Edition

67. When does it make sense to get Windows Server Datacenter versus Standard Edition?

It depends on your needs, but a rule of thumb is that if you think you might ever need to run near 10 or more

Windows Server virtual machines on a server, then Datacenter, with its unlimited virtualization rights, is the

best choice.
