So follow up to my question, if the above is not possible, should I just allocate the remaining 200 GB or so in my RAID1 drives that have the hypervisor isntalled, and make that for the VM files? Then I could just add one more drive for data? I could theoritically make a Windows 8 as a VM and make sure that autostarts, than people can just RDP to it, or install the management tools onto their local pc (I do understand that part of it).
When I was reading the supported Host OS list, it appeared it was compatible with basically all versions of Windows, and that's why I thought I could install Windows 8 and than install the VSphere software on it...
