Weakening of the SCSI Standard

[Gene Milligan]

SCSI obviously is pervasive at the high end where vendors are able to invest
considerable engineering effort to achieve a workable system. In part, the
effort is considerable because the SCSI standard allows troublesome variations
by employing weak "should" requirements.
 
I notice that in the working group minutes there is an indication that the
standard will be further weakened by removing the stub length requirement and
just giving some weak recommendations. If the stub length does not matter don't
mention it. If it matters specify absolute tolerances.
 
Items like this are not statistical per se. The node capacitance of a device
will not be lower just because the user wants many per system. There does not
seem to be a body of evidence that SCSI has been too tightly specified.
