By now the whole virtualization world should be aware that VMware took the big step of releasing its flagship hypervisor as a free product: ESXi 3.5.
Despite that, maybe not everybody knows that this free platform has some limitations compared to the fully-featured ESX 3.5.
To clarify the things VMware published a new knowledge base article with a valuable comparison matrix.
Please note that this table is only focused on the virtualization host capabilities and doesn’t consider all the features that VirtualCenter can bring in. This avoid any confusion that previous comparison (for example ESXi stand-alone vs ESX+VC) could imply.
