An Open Letter to Apple on Server Technologies
Some of our smaller departmental or lab users may be able to run Mac OS X Server on a Mac Pro or Mac mini. At a campus level, we cannot, because these systems do not have the required mounting, power, management, and other functionality. While it is possible to rack mount a Mac Pro with third-party hardware, it is a non-starter because of the lack of dual redundant power supplies, management capabilities, and spare parts kits, to say nothing of space considerations.
Please allow virtualization of Mac OS X Server in non-Apple virtualization environments, with a commensurate license and pricing model.
