The new rig consists of 7 Mac Mini mid-2011 servers, each connected to an M-Audio ProFire 610 interface for MIDI and audio. Each player in the Ensemble has his own dedicated computer. I chose this Mini model because it has a quad-core processor and dual 500GB internal hard drives. I’m not using any server functions on it. The second internal drive is a clone of the first, maintained by Carbon Copy Cloner; whenever the machine boots up, the clone is updated and older files archived. All computers are run headless via Ethernet from a MacBook . All machines have identical software loads, except for their manual IP addresses and desktop pictures which have the computer name embedded in them so I can tell which one I’m looking at. I have written a number of custom Applescript applications as front ends for rsync to manage synchronization between machines, a subject worthy of a separate discussion, so I won’t go into that now.
While not directly related to Photography I found this interesting on how they solved these issues. I like the use of mac minis as well. I am looking for some options for a render farm and I may do something like this.
