HSD10 DSSI-to-SCSI Bus Adapter Description
The HSD10 DSSI-to-SCSI bus adapter provides connectivity for up to seven SCSI disks or
six SCSI disks/CDROMS and one SCSI tape device through a single port on the DSSI bus.
The DSSI bus is connected through the CPU module. One accessible connection is also
available through the expansion port on the rear of the enclosure.
The HSD10 is a TMSCP/MSCP-compliant device that performs the translations required
to support devices conforming to SCSI or SCSI-2 protocols. The HSD10 supports
embedded SCSI devices in VAX 4000 Model 108 systems
