I am setting up a late 2012 Mac Mini as a file server with Server 2.2. It has a Promise Pegasus R4 RAID and LaCie 4TB drives daisy chained via the thunderbolt connection. 4 users on MacPro's will connect to the server to access these hard drives via gigabit ethernet. I imagine the gigabit ethernet will be the bottleneck, so I'm now looking at link aggregation. Not a problem on the MacPro's but the Mac Mini will require an adaptor to get a second gigabit port. From reading this forum I understand the Apple Thunderbolt to Gigabit adaptor will work, but I'm concerned that it will need to be fitted 3rd in line after the R4 and LaCie drives. The 10Gbps bandwidth Thunderbolt has, may cause another bottleneck with all three working off the same port? An option would be to use one of the USB 3 ports with this adaptor http://www.ebuyer.com/412005-starte...b31000s?utm_source=google&utm_medium=products I believe it work with OSX, but I have no speed information or if OSX link aggregation will work using it. Any thoughts on the above would be appreciated and recommendations on a suitable Network Switch with LACP support welcome.
