Windows Server R2 | Microsoft Volume Licensing

 

We should note that the Standard edition supports up to 2 Virtual Machines. The Windows Server R2 Datacenter edition is the flagship product created to meet the needs of medium to large enterprises.

The major difference between the Standard and Datacenter edition is that the Datacenter edition allows the creation of unlimited Virtual Machines and is therefore suitable for environments with extensive use of virtualization technology.

Before purchasing the Windows Server operating system, it is very important to understand the difference between various editions, the table below shows the difference between the four editions of Windows Server For example, a CAL assigned to a user, allows only that user to access the server via any device.

Likewise, if a DAL is assigned to particular device, then any authenticated user using that device is allowed to access the server. We can use a simple example to help highlight the practical differences between CAL and DAL licensing models and understand the most cost-effective approach:. Assume an environment with Windows Server R2 standard edition and a total of 50 users and 25 devices workstations.

In this case, we can purchase either 50 CAL licenses to cover the 50 users we have or alternatively 25 DAL licenses to cover the total amount of workstations that need to access the server.

In this scenario, purchasing DALs is a more cost effective solution. If however we had 10 users with a total of 20 devices , e. Windows Server Foundation is available to OEMs Original Equipment Manufacturers only and therefore can only be purchased at the time of purchasing a n new hardware server. Windows Foundation edition supports up to 15 users. In addition, Foundation edition owners cannot upgrade to other editions. The Essential edition of server is available to OEMs with the purchase of new hardware and also at retail stores.

The user limit of this server edition is 25 and device limit is This means that a maximum of 25 users amongst 50 computers can access the Windows Server Essentials edition. For example, you have 20 users rotating randomly amongst 25 computers accessing the Server Essentials edition, without any problem. A common question at this point is what if the organization expands and increases its users and computers?

In these cases Microsoft provides an upgrade path allowing organizations to upgrade to the Windows Server Standard or Datacenter edition license and perform an in-place license transition. Once the transition is complete, the user limitation, and other features are unlocked without requiring migration or reinstallation of the server. Companies upgrading to a higher edition of Windows Server should keep in mind that it will be necessary to purchase the required amount of CALs or DALs according to their users or devices.

A single license covers up to two physical processors. Here are just a few examples: Enterprise-class virtual machine density, performance, and mobility with best-in-class performance and scale for Microsoft workloads High-performance file-based storage on cost-effective, industry-standard hardware with inbox storage virtualization and tiering Highly available, in-box hybrid networking for bridging physical and virtual networks in a multi-tenant environment and across premises Protection and recovery of assets for all your workloads with simple and affordable disaster recovery options Flexible remote access to corporate resources from virtually anywhere and on any device while helping to protect corporate information.

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.
