For SE Fast20 ("Ultra") you should not exceed 1.5m per the SCSI-II spec.
Stubs should not be positioned closer together than 0.3m.  SCSI-III
modifies some of these but in a complex way.

So, for best results you should have no more than 5 feet of SCSI cable,
with devices no closer together than 1 foot.  You can of course stretch
these limits and get away with it most of the time.
