Module Description
Purpose of the
Module

The KZTSA storage adapter is a versatile, intelligent, highperformance TURBOchannel option module. It serves as a
pathway between the system’s TURBOchannel I/O bus and a
single local 16-bit differential SCSI bus.
For versatility, the storage adapter’s local 16-bit differential
SCSI bus can be hardware configured, using appropriate cabling,
to interconnect with either 16-bit or 8-bit differential SCSI
devices that are grouped and housed within storage enclosures.
The system architecture of the KZTSA storage adapter is shown
in Figure 1–1.

1–6 KZTSA Adapter Overview

General Overview

General Overview
Open Systems

The KZTSA storage adapter can be used on many of
the workstation or server platforms that incorporate a
TURBOchannel bus as the system I/O bus.
Consult the appropriate Digital literature for a list and
description of supported workstation or server platforms.

Open Operating
Systems

The KZTSA storage adapter can be used on multiple operating
systems. Consult the appropriate Digital system software
product description (SPD) for a list and description of supported
operating systems.

Open Storage
Bus: SCSI

The KZTSA storage adapter uses the small computer system
interface (SCSI) architecture for connection to SCSI devices. For
example: SCSI devices include controllers, bus converters, or
removable and nonremovable tapes and disks.
This architecture allows for the expansion of the host system’s
storage area. Many vendors manufacture SCSI devices, and
connection of these devices is made easy through standardized
connectors and cables.

KZTSA Adapter Overview 1–7

General Overview

Optional SCSI
Devices

The KZTSA storage adapter directly supports up to 15
differential 16-bit (depending upon the operating system) or
up to 7 differential 8-bit SCSI devices. For example, the SCSI
device could consist of a:
•

16-bit differential disk array controller

•

16-bit differential to 8-bit single-ended bus converter

•

16-bit differential removable or nonremovable tape or disk

•

8-bit differential removable or nonremovable tape or disk

The storage adapter can also indirectly support single-ended,
8-bit or 16-bit SCSI removable or nonremovable tapes or disks.
Important
The KZTSA-AA storage adapter cannot directly support
single-ended, 8-bit or 16-bit SCSI devices. For these
devices, a differential 16-bit to single-ended 8-bit or
16-bit SCSI bus converter or disk array controller must
be ordered separately.
By using the appropriate bus converters and cables, 8-bit
or 16-bit single-ended and 8-bit or 16-bit differential
devices can be mixed. See Table 2–3 for additional
guidelines.

Utilizing the appropriate converter, up to 7 8-bit or 15 16-bit
(depending upon the operating system) single-ended devices are
supported.

Priority
Arbitration

SCSI bus priority arbitration is based on the SCSI ID of the
arbitrating device. Priority arbitration is established from
highest to lowest.
For example, in the following priority arbitration scheme, SCSI
ID 7 has highest priority and SCSI ID 8 has lowest priority:
SCSI ID 7-6-5-4-2-1-0-15-14-13-12-11-9-8

2–4 System Configurations

Differential SCSI Bus

Configurations

The KZTSA adapter can be configured within the middle of the
bus (mid-bus) or the end of the bus (end-bus) depending on the
balancing scheme used on the bus; that is, the physical location
of bus terminators on the bus in relation to the KZTSA adapter.
For a mid-bus configuration, the bus is not terminated on the
KZTSA adapter (onboard terminators are removed). A "Y" cable
or a tri-link connector is used to position the KZTSA adapter in
the middle of the bus. The bus is terminated at the end SCSI
device using a 68-pin p-connector terminator.
For an end-bus configuration, the bus is normally terminated
on the KZTSA adapter using its onboard terminators, while the
other end of the bus is terminated at the end SCSI device using
a 68-pin p-connector terminator.
Note
Refer to Table C–3 for the documents that contain
the Digital part number for the "Y" cable and tri-link
connector block.
"Y" Cable (BN21W-0B)
Figure 2–2 shows a "Y" cable configured for a mid-bus

System Configurations 2–9

Differential SCSI Bus

Termination

The integrity of the data written to or read from a differential
SCSI device can be seriously compromised due to signal
reflections derived from an unbalanced bus. An unbalanced
bus is the result of an improperly or nonterminated bus.
Therefore, failure to terminate the bus properly may result in
data corruption or, worst yet, a system crash.
A balanced bus is determined by the physical location of bus
terminators on the bus in relation to the KZTSA adapter and
SCSI device.
In summary, to avoid bus reflections, the bus must be properly
terminated at both ends to operate reliably.

Termination
Options

Termination of the bus involves supplying terminator power onto
the bus and the strategic placement of terminators on the bus.
Normally the KZTSA storage adapter provides active termination
of the differential SCSI bus for either mid-bus or end-bus
configurations by supplying terminator power onto the
bus. However, a SCSI device could also provide this active
termination, in which case jumper W3 on the KZTSA storage
adapter would be removed.
The strategic placement of terminators on the bus in relation to
the KZTSA storage adapter and the SCSI device is determined
by the KZTSA storage adapter’s placement on the bus; that is,
whether it is a mid-bus or end-bus configuration. For example,
the adapter’s onboard terminators are removed for a mid-bus
configuration and installed for an end-bus configuration. The
end SCSI device is then terminated, using either onboard or
external terminators; that is, onboard terminators if the device
contains a single SCSI port p-connector, or external terminators
if the device contains dual SCSI port connectors. The external
terminator is simply a high-density, shielded differential
terminator housed in a male p-connector.

2–10 System Configurations

Differential SCSI Bus

Table 2–4 lists the onboard and p-connector terminators used in
terminating the differential SCSI bus.
In summary, active termination simply implies whether the
KZTSA storage adapter or the SCSI device supplies termination
power onto the bus. This termination power is then used by a
terminator(s) that contains a series of pull-up and pull-down
resistors, which make up the termination process.

13–36034–01

SCSI device

H879–AA

A Digital supported SCSI device can be warm swapped provided
that a "Y" adapter is used and the bus is properly terminated.
By using a "Y" adapter, a SCSI device could occupy either a
mid-bus or end-bus position, yet remain removable for service.
A "Y" adapter, whether a cable or tri-link connector, provides the
following capabilities:
•

Mid-bus connection for single-connector SCSI devices

•

Online removal of mid-bus SCSI devices without disrupting
service to other SCSI devices

•

Online removal of end-bus SCSI devices without disrupting
service to other SCSI devices

Sample Configurations

Sample Configurations
Overview

This section describes three possible configurations in which
differential and single-ended SCSI devices, housed within
a storage enclosure and external to the host system, are
interconnected by way of the KZTSA adapter’s external SCSI
port connector.
A summary of the three configurations follows:
Configuration #1

Illustrates an end-bus configuration whereby
the KZTSA adapter interconnects by way of a
point-to-point cable connection to a bus converter
housed within a Digital storage enclosure. The
bus converter, in conjunction with the storage
enclosure, provides a single-ended SCSI bus in
which six 8-bit SCSI devices are attached.

Configuration #2

Illustrates an end-bus configuration whereby the
KZTSA adapter interconnects by way of a point-topoint cable connection to a RAID subsystem housed
within a Digital storage enclosure. The storage
enclosure provides five single-ended SCSI buses in
which six 8-bit SCSI devices are attached to each
bus.

Configuration #3

Illustrates a dual host mid-bus configuration
whereby two KZTSA adapters connect to a
bus converter housed within a Digital storage
enclosure. 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.

Device Parameter Disable Utility F–3

Using the Device Parameter Disable Utility

SET Command

The SET command allows one of the four activities to be enabled
or disabled for the specified device.
For Alpha AXP based workstations or servers, the format for the
Device Parameter Disable utility SET command is:

DevParams>set [device_id|ALL] [SYNC|WIDE|DISCON|TAGQ] [ENABLE|DISABLE]
or
DevParams>set [device_id|ALL] DEFAULT
The device_id can be entered as a decimal or hexadecimal
number, for example, as 11 decimal or as 0xb hexadecimal.
Using the DEFAULT qualifier with the SET command enables
the four activities on the specified device or on all devices on the
SCSI bus.
The following display is an example of using the SET command
to disable wide negotiation on the device that has a SCSI ID of
10:
DevParams>set 10 wide disable

Return

?DevParams: Adapter must be reinitialized for changes to take effect
DevParams>
After using the SET command, the SHOW command can be used
to verify that the desired activity was enabled or disabled on the
selected device.

one of the address signal lines.
self-test
Program test that is invoked automatically when the system
starts up.
target
SCSI device that performs an operation requested by an initiator.
terminator
Resistor array device used for terminating a SCSI bus. A SCSI
bus must be terminated at its two physical ends. A peripheral
device uses a terminator only if it is at the end of the bus.
TURBOchannel
System’s synchronous, asymmetrical I/O channel.
