Yes, I'm a bit of a masochist. So here is my plan: 1) Four 2 TB drives connected to a RAID card. I'd like this data to be as OS neutral as possible, preferably accessible through ESXi, OSX, and Windows under boot camp. 2) A single SSD which will house the OSX and Windows 7 boot camp partitions. My questions: 1) Which RAID card? It sounds like the Apple one is a rip off and doesn't work very well, so I'd like to go ATTO or Areca. The only requirements is that they are capable of 6 GB, ESXi compatible, and will work with the setup I have listed above (both operating systems). I'd like to spend as little as possible, so I'm leaning towards an 11XX or 12XX series controller from Areca. RAID 10 at a minimum and RAID 6 would be ideal. 2) Is there a recommended SSD (I've heard the new Intels are best)? 3) Has anyone gotten ESXi to successfully work on their Mac Pro? I have found references to people getting it to work in the VMWare forums but haven't tried it myself. Ideally, I'd like to have it setup so I can boot off USB, and will boot into ESXi. If I pull the thumb drive, it will boot up to OSX or Windows depending on which I select. The RAID storage is agnostic and will work with all three systems. So please, shoot holes in my plan or let me know if you have any experiences getting this going.
