At a guess it's an external box which
emulates a SCSI hard disk, but consists
of a RAID processor and a bank of drives.
Any configuration/rebuild is controlled
by a front panel.
There are also 2 or 3 drive + CPU combos
you can get for PCs which again emulate
a single IDE/SCSI drive. These typically
have hot swap trays and a small LCD to
control them, so that the host PC needs
no extra hardware or software. Quite a nice
way to do it, but not very cheap.

Our main Venti server runs on a big RAID.
I don't know details of how it works, but
it does work. Presumably it does imitate
a really big disk.
There's definitely no support for software
RAID, though if you want mirroring there's fs(3).
