That's the abstract from EPI. I agree it needs to be completely
rewritten for SDV.
While on the topic of SDV, here's where I see the SDV content going:
a) Move expander communication mechanism(s) (the multibit selection
method and the "out-of-band" method) into SPI-4. This will help ensure
that SPI-4 initiators are capable of doing such communication. If
they remain buried in another document, they're more likely to
At a minimum, software control of the SCSI lines will be needed.
The multibit selection method can probably be automated by the
standard hardware, provided the multibit "target" IDs are supported
and broadcast timeout handling is added.
b) Move the multibit selection method expander SCSI commands into a
full-fledged Expander Command Set.
c) Leave the domain validation algorithm discussions in the SDV
technical report. This would focus on what the different levels
of domain validation mean, discuss how to handle multiple
initiators correctly, and provide other advice on how to use the
tools in a) and b).
