VKernel is offering perpetual license for their Capacity Modeler from now through the end of the year. I have not had time to take a look at the product, the price is definitely right to add to the bag of tools I carry around. I will write more on this once I’ve had time to take a look.

Now through December 31, 2009, you can download VKernel Capacity Modeler absolutely free — these are perpetual licenses for use on unlimited sockets.

VKernel Capacity Modeler is a free alternative to the expensive VMware vCenter CapacityIQ software, which can cost you upwards of $1,000 per socket.

The free VKernel Capacity Modeler software provides VMware customers the ability to quickly plan, simulate, and validate hundreds of real–world “what if” VM deployment and resource allocation scenarios in an interactive sandbox before going live in the production environment.

With VKernel Capacity Modeler, user can perform:

• Capacity Planning
• Interactive “What If” Modeling Scenarios
• Proactive Problem Prevention
• Predictive Capacity Impact Analysis
