The Windows Server Division Weblog posted a link to this tool today. In Microsoft’s words:
The Windows Server Virtualization Calculator provides two ways to estimate the number and cost of Windows Server Standard Edition, Enterprise Edition and Datacenter Edition licenses needed for your virtualization scenarios to help you determine the most cost-effective edition of Windows Server.
One of the MCS team also blogged about this online tool and reminded us that this tool will also be useful for those considering VMware technologies instead of Microsoft’s solution.
