We use a pair of Synology DS 1812+. The user interface on these servers is very friendly for us non-IT types, and there are plenty of security and automation features. For example, our server is setup to only allow access via the University subnet, and only SFTP access. Setting up unique encrypted accounts is a breeze, and I also have the server running a virus scan and SMART scan each night, as well as more thorough checks over the weekend. Our backup server powers on only for the backup and a quick diagnostic self-check. All in all, the system has been very nice and supports hybrid raid for memory expansion, as well as two external bays for a total of 18 drives. We've also gone with 3TB drives rather than 4TB just to stay away from the "bleeding edge" of technology.
In my opinion, when you have to come in on Christmas day because the server failed to backup, you will greatly appreciate having something that's user friendly.

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'.
