These are relatively inexpensive network storage boxes using SATA drives
and AoE (ATA over Ethernet) connection to the server. Drivers build
easily on CentOS.
Just make sure you get drives that are on their compatible list. This
may not be as much of an issue now, but I had some problems with drives
being marked bad and dropped out of the array when I first set up mine a
couple of years ago. This was caused by firmware incompatibilities and
fixed by upgrading the drive firmware. Once this was fixed, everything
has worked flawlessly since.
