Actually, that's not *quite* correct. The IDE drive would look like one drive. 
All the SCSI drives would then be RAIDed together into a single large drive.
(I have no idea how it determined what blocks to put on what drive.)

It did work well with Linux. I also seem to remember getting some version
of BSD to install on it. (Probably and old 386BSD.)
