Max secondary storage

Is there an inherent maximum limitation to the amount of physical secondary 
storage, specifically hard disks or cdrom, one can access under SCO UNIX 
3.2v2.0 excluding type RFS or NFS?  I checked out /usr/include/sys/params.h 
but couldn't find what (I thought) I was looking for.

Theoretically what I'd like to be able to do is install nine DPT 2012B/90 EISA
SCSI host adapters on one system and hang seven 1.2GB drives off of each for a
total of 75.6GB, possible more if I subsititute large-capacity cdroms for some
of the disks.  Besides device driver mod's to subvert the major number/minor
number restriction under SCO which only allows four disk drives per host 
adapter, what other kernel mod's would I need to investigate in the i/o
subsystem?  I believe there's also a two host-adapter per system restriction
but I'm not sure.  Any info would be greatly appreciated.
