Windows Server CALs are required for every user or device accessing a server. Customers can purchase a Windows Server 2012 R2 CAL from IBM either for every device (used by any user) accessing their servers, or for every named user accessing their servers (from any device).
The option to choose between the two types of Windows CALs offers the flexibility to use the licensing that best suits the needs of your organization. For example:

Also, some additional or advanced functionality will continue to require the purchase of an additive CAL. These are CALs that you need in addition to the Windows Server CAL to access functionality, such as Remote Desktop Services. Remote Desktop Services 2012 CALS are also available from IBM.

If you are not ready to upgrade to Windows Server 2012 R2 or 2012, IBM continues to support Windows Server 2008 R2. However, IBM does offer a downgrade kit to Windows Server 2008 R2 so that you can purchase the latest software features of Windows Server 2012 R2 and downgrade if you need to. The Windows Server 2012 downgrade kits include both Media and Activation Keys. When downgrading from Windows Server 2012 R2 to Windows Server 2012 or to Windows Server 2008 R2, the licensing rights of the Windows Server 2012 R2 product is maintained.
