At the time it was developed SCSI was maybe SCSI-1 or II and way short on
perfomance, limited in number of possible connected devices and short on
cable length. DSSI like many of the DEC storage interconnect was trying
to
address problems like cable length (wanted longer), rate of
transmission(faster)
and cluster interconnect. It's also a protocal and within that it
addresses
best ways to move data faster and route it.

Yes.
