I came across Ben Armstrong’s Blog today while doing a little searching. He has some good stuff about Microsoft Virtual Server on there and one of the things he posted on has to do with a calculator to figure out how to configure your Virtual environment. It doesn’t take much to figure out that Data Center Edition may actually be worth paying for when you use multi-core processors and pack a lot of VMs on one host.
Windows Server Virtualization Calculator
I do not know how I missed this one, but this is a very cool tool. The Windows Server Virtualization Calculator allows you to specify how many virtual machines you will be running, on a given set of hardware, and it will show you all of your licensing options for buying Windows Server. This way you can quickly determine what the best option is for your environment.
