That's because they have hardware RAID, with that built in at the
hardware itself, the drivers designed for that chassis, and the
management tools for it. Unpeeling that to say "make it work on
Linux!" would be unfair: we couldn't make a good guess without knowing
the actual *hardware* of your Linux File Server. And we can't even
guess what the available displays of your drive enclosure are.
Why are you doing this when a commercial solution with such featurs,
equipped with 1 TB drives, costs less than $10,000 with all these
goodies and the superior performance of hardware RAID thrown in?
