Looking to upgrade our aging Mac Pro Tower and Promise Storage Via Fiber. We are an Ad agency with 86 workstations and the only service running is File sharing. (All other services cloud based, Gmail etc. ) Was looking at the new Promise Thunderbolt Raid, however the mini's lack of Thunderbolt 2 pushes us into a MacPro Tower. Shelling out 3K for only file sharing seems a waste. Windows server options were looked at but after you factor licensing, support etc., you are at the MPT price point. Anybody in a similar situation? SIDE NOTE, We have about 16 TB of live data.
