Choose from three primary editions of Windows Server based on the size of your organization, as well as virtualization and datacenter requirements. The following page is intended to provide you with reference pricing for Windows Server For specific pricing, please contact your Microsoft reseller.
Datacenter [2]. Standard [2]. Specialty servers server license [3]. See the Product Use Rights for details. Please contact your Microsoft representative for a quote. Storage Replica [2]. Pricing and licensing for Windows Server Choose from three primary editions of Windows Server based on the size of your organization, as well as virtualization and datacenter requirements.
You see, we're almost there. The 11th VM will make difference. The Windows Server licensing is cheaper when running more than 10 VMs and taking the Datacenter license. Again, I'll demonstrate with an image, where you'll see that the requirements to run 10VMs per host must be kept. I'm assuming that during the normal workload five VMs run on each host. In case you want to move 5 VMs to any of those 2 hosts, then each of the host has to have enough assigned Windows Standard licenses.
Also the requirements to cover both hosts with at least one license to match the physical CPU requirements. A multiple standard licenses are needed to stack to match the 10 VMs which runs in the environment. Recently I was thinking that running vCenter Server Linux appliance would lower the costs of the licensing for smaller shops, but it seems that only a good planning and the exact needs is the way of calculating the costs. You can still read that article if you want to see the steps required to deploy and configure the vCSA in your environment.
There is also a datasheet and a FAQ with more details. Connect on: Facebook. Feel free to network via Twitter vladan. Regarding physical sockets there is clear statement that each physical CPU of the host have to be licensed. What does it means. Because there is feature parity between Windows Server R2 Standard and Datacenter editions, your decision will be based on your virtualization strategy, as virtualization rights are the only differentiator between the editions.
If your strategy calls for a highly virtualized environment, Datacenter edition will provide you with optimum flexibility because it allows for unlimited virtualization. This edition gives you the elasticity to add and move virtual OSEs across Datacenter licensed servers without needing to track the virtual OSE count on that server.
If you purchase Standard edition today but find you need to expand the virtualization capacity of your licensed server, you can do one of the following: Purchase additional Standard edition licenses and assign them to the same physical server, giving you the rights to run additional instances of Windows Server.
The server must have the appropriate number of licenses assigned to it to ensure coverage of all of the virtual OSEs that are running at any given time. Purchase a Software Assurance Step-up license to Datacenter edition, changing the license to a higher edition that allows unlimited virtual OSEs. To use this benefit, your underlying license must have Software Assurance. With the Windows Server R2 Standard edition licensing model, you can grow your virtualization environment by either buying a step-up license to Datacenter edition if you have Software Assurance, or by simply buying additional Standard edition licenses and assigning them to the same physical server.
For example, if you have a two-processor server and want to run a total of four VOSEs, you can purchase two Standard edition licenses and assign them to the same server. Additional examples are shown in the following table. Windows Server R2. Windows Server R2 captures the experience Microsoft has gained from building and operating public clouds to deliver a highly dynamic, available, and cost-effective server platform for your datacenter and private cloud.
The following information provides an overview of your key licensing options.

Datacenter edition is ideal for customers who want to have a highly virtualized private and hybrid cloud environment.
