They should work fine, some of the drives that Sun shipped in the SS5/SS20
were actually wide SCSI (capable of using ID's from 0 to 15).  The small
interface board that the drives plug into sets the ID's.

One thing to watch out for are the new LVD drives.  Some of these
correctly autonegotiate down to SE narrow SCSI mode, some of them don't.
Nearly all of the do negotiate correctly to a wide SE controller (which
the SS20 does not have).
