The story on CAL’s
• Server + CAL model• External connector option• Device CAL’s versus User CAL’s
Product Licensing
• “Microsoft Licensing is difficult to understand”– Licensing – “How can a professional organisation acquire its
software licenses” – is relatively simple– Product Licensing – ‘What can I do with the software for which
I have a license?’ or ‘What licenses do I need to put together this infrastructure’ is more difficult and evolves quickly.

Virtualization Use Rights1 4 Unlimited Unlimited
Hyper-V & Windows Licenses
• Hyper-V Server 2008– Each guest OS requires a license
• Windows Server 2008 Standard Edition– 1 License for Virtual Machine included
• Windows Server 2008 Enterprise Edition– 4 Licenses for Virtual Machines included
• Windows Server 2008 DataCenter Edition– ∞ Licenses for Virtual Machines included
Included Virtual Licenses
CPU based Licensing
(1 multicore = 1 CPU)
More interesting when able to have 3 or more VM per CPU
Physical VirtualBasic Differences in licensing
Physical
• License required when software installed– OS– Applications
• Exception:– COLD stand-by in Software
Assurance
Virtual
• License required– Per “running instance”– OS– Applications
Virtualization User Rights
Each “Assigned”Enterprise License on
Host
4 Server Licenses for Virtualisation
Independent of virtualization technology
1/4/Unlimited Virtual Licenses
• Virtual license bound to “physical” license– No split possible
• Need # Virtual licenses as MAXIMUM # instances that might run– Per box
• Licenses can be transferred to other hardware– Dismissal of host– After 90 days for OS, instantly for Server Apps– Not with OEM Licenses

Server Virtualisation – rules of thumb
• Windows Server Host OS often gives right to some free Guest OS’es
• For Application Servers licensed ‘per CPU’, you only need to count virtual CPU’s in the VM
• Microsoft only requires license for running instances of an OS or application
• All our licensing rules with regards to virtualisation are independent of Virtualisation Technology
• Also OEM licenses give virtualisation rights, but remain linked to hardware
Server Application Re-assignment
• Sept 1 announcement: ‘Microsoft waives the 90 day rule on license re-assignment’
• Details:– For application server only– Only for Volume Licensing– Within a limited time zone– Allows easier VM swapping to other hardware– Independent of virtualization technology used
• Rule of thumb: if a customer moves a running instance of a virtualized server application to other hardware, he can do so freely, but needs to check on the server OS licenses.
