I have a 2012 iMac and a Drobo 5D (Thunderbolt Mass Storage) where I store all of my iTunes movies, music, etc. Both devices here have Thunderbolt capability. The iMac and the Drobo 5D are connected via Thunderbolt and this is how I manage and share my iTunes library. I then use Home Sharing via iTunes and play said media on my Apple TV3. Of course this only works when the computer is on. Here is where the conundrum begins. I also need to use bootcamp quite often. When I do, the shared media disappears (obviously) and it leaves others in the house unable to view said media via Home Sharing on the Apple TV.
Is there a way for me to have 2 Mac desktops hooked up directly via thunderbolt to the same storage device such as my Drobo 5D?
Essentially, my ideal workflow would be something like...
iMac: Manage iTunes media and store it on the Drobo 5D
Mac Mini: Take the stored media and Home Share it via iTunes to ATV3
ATV3: Play back the stored media from the Drobo 5D that is shared out via Mac Mini
Note - All connections need to be Thunderbolt as I've found that even when connected via Gigabit Ethernet, there is too much congestion for the ATV3 to handle (poor playback).
