We use a series of Pegasus RAIDs sold by Promise. They use twin Thunderbolt
ports so you can daisy-chain a bunch of them together (one port to the
host, other port to the next chassis in the chain). The biggest chassis has
8 bays, and you can put a 4TB drive in each bay for 32TB per chassis. They
tend to be a bit cheaper than 'real' enterprise solutions and seem fairly
reliable. We've had ours running for a few years now (an earlier 4 bay
model) with no issues. We recently added an 8 bay system (Pegasus2) as well
and they seem to play well together. One hitch is to make sure your
thunderbolt drivers are up to date for the newer models. A current Mac Mini
Server can manage these systems fairly simply on a network without being
too expensive. Just make sure to buy a spare hard drive or two when you buy
them so you have a drive on hand that matches the original set. It will
make dealing with any drive problems much quicker. I tend to keep a single
module per chassis in reserve just in case, although I have yet to use any
of these 'spares'.
