I hope someone smarter than me comes up with vCenter unlocker as Apple once again ignored releasing "real" Mac Pro.
All my PC's are Mac's (even livingroom HTPC with MCE is running on Mac Mini) but I just cant justify buying new Mac Pro for my server. (I still have 2008 Mac Pro but it's even slower than current QuadCore Haswell while consuming 2.5 x times the power )
No iLOM, no internal storage (so good bye VSAN), no RAID, (for server use) useless 100 WATT GPUs .... It's nice workstation but by no means replacement for currently (very old) Mac Pro.
I am sure we all understand where you are coming from, I think if Apple want OS X Server to live in the virtual world, they are going to have to revise their EULA, we are all happy to pay for OS X Server, but since Apple do not have any server grade hardware what are we supposed to do? VMware quite clearly have the Hypervisor capable of delivering virtual OS X Server, just not the legal right to allow it!
Come on Apple time for a radical rethink, you have done it with the recent free release of OS X Mavericks, what about extending that to the OS X server in the virtual world. I wonder what Apple run as servers for their own infrastructure, clearly not the old Mac Pro, and certainly not the new Mac Pro, much as we all love both, and are saving our money for the new Mac Pro!
