You're probably thinking of an A3000.  The 3000 control "unit" up top is chained
to multiple D1000 drive "shelves".  The 3000 does the hardware RAID.

Okay, rundown:

 A1000 = 8 or 12-slot drive "shelf" with hardware RAID controller integrated
 D1000 = 8 or 12-slot drive "shelf" with no hardware RAID; its just a JBOD/
         enclosure
 A3000 = hardware RAID controller connected to multiple D1000s

 If I have the time, I'll bring my digicam to work this weekend and take some
 pictures of A3000 setups.
