Sample KZPSA Adapter Configurations

This appendix describes three possible configurations in which differential and single-ended

SCSI devices, housed within a storage enclosure and external to the host system, are intercon-

nected by way of the KZPSA adapter's external SCSI port connector.

B.1 Configuration Summary

Table B–1 presents a summary of three configurations of how to connect the

adapter to a storage enclosure and external host.

Configuration Description Figure

Bus Converter Illustrates an end-bus configuration whereby the

KZPSA adapter interconnects, by way of a point-to-

point cable connection, to a bus converter housed

within a Digital storage enclosure. The bus con-

verter, in conjunction with the storage enclosure,

provides a single-ended SCSI bus in which six 8-bit

SCSI devices are attached.

B–1

RAID Subsys-

tem

Illustrates an end-bus configuration whereby the

KZPSA adapter interconnects by way of a point-to-

point cable connection to a RAID Subsystem

housed within a Digital storage enclosure. The

storage enclosure provides six single-ended SCSI

buses in which three 8-bit SCSI devices are at-

tached to each bus.

B–2

DECsafe ASE Illustrates a dual host mid-bus configuration

whereby two KZPSA adapters connect to a bus

converter housed within a Digital storage enclo-

sure. The bus converter, in conjunction with the

storage enclosure, provides a single-ended SCSI

bus in which six 8-bit SCSI devices are attached

and shared between the two hosts.
