IBM's SCSI host interface works "out of the box" with their 678 "Athens" 200mb
and 400mb humongous 14" drives.  This may be out of your league -- size,
price and power-wise.  I suspect that it will work with other SCSI disks,
but it would probably require some amount of driver hacking.

I can't comment on AIX, but if you're running AOS 4.3, I highly,
highly, highly recommend avoiding the IBM SCSI interface and getting
Christer Bernerus' driver for the Adaptec AHA-1450A SCSI interface, a
PC/AT board which is very inexpensive: < $300.  His 4.3 device driver
is written the RIGHT way, so that device drivers of all types can be
slipped beneath the generic controller code.  He provides a Maxtor
4380S hard disk driver and a SCSI streaming tape driver, both of which
give you adequate boilerplate to write a driver for any kind of SCSI
device you want--I'm working on a CD-ROM driver right now based on his
hard disk driver.  I got the disk driver working with a Newbury Data 4380S
unit with a minimum of tweaking (mainly in defining the templates for
the MODE SENSE command, since different drives return different
pages.)  A Maxtor 4380S should work out of the box.

His code comes with a standard university-style disclaimer/copyright.
I don't know what his opinion is regarding this publicity, but I am
one very pleased individual.  His address in Sweden is
	bernerus@utc.chalmers.se.
