Hi folks! So now with 6 core processors readily available for servers, the questions about VMware and multi-core licensing are starting to crop up again.
Generally you license based on a certain amount of cores, and if you exceed that, you buy a license to upgrade you to more cores. However you cannot split cores in a license across multiple processors.
6 core processors are great for virtualization, and that coupled with the ability to put large amount of memory in servers these days will make for some very powerful virtual environments.
