Overview
This chapter provides an overview of the KZPBA–CA PCI-to-Ultra SCSI Host Adapter.
The KZPBA–CA is an ultra wide single-ended host adapter.
1.1
Introduction
The KZPBA–CA host adapter module provides the interface between the host
computer’s PCI bus and internal and/or external SCSI devices. The KZPBA–CA
combines a powerful Reduced Instruction Set Computing (RISC) processor, a
SCSI executive processor, and a PCI local bus interface on a single chip.
The KZPBA–CA is a leading edge host adapter that supports bootable devices
and provides a powerful multi-tasking interface. The SCSI bus can be connected
to disk drives, CD-ROM drives, scanners, tape drives, and other SCSI devices.
More than one KZPBA–CA host adapter can be installed in the same host
computer. Each host adapter and its associated SCSI devices form a separate
SCSI bus.
The RISC processor minimizes the overhead of the host computer’s
microprocessor by transferring data directly into the host computer’s memory. It
also manages the actual data transfers between the host computer and the SCSI
devices without involving the host computer’s microprocessor.
The SCSI processor negotiates with each device on the SCSI bus to establish the
data transfer rate between the host adapter and each SCSI device. It also
automates SCSI command processing and significantly reduces the number of
interrupts and command overhead.
The KZPBA–CA is capable of 32-bit bus master data transfers, including PCI
enhanced data transfer commands. The host adapter supports all SCSI-2 and
SCSI-3 functions.
EK–KZPBA–UG. B01
1–1
KZPBA–CA PCI-to-UltraSCSI Host Adapter
The host adapter supports multithreaded I/O operations, thereby allowing
simultaneous operations on multiple SCSI targets or Logical Units (LUNs). In
systems with multiple targets, the Disconnect/Reconnect feature optimizes SCSI
bus usage. In systems that have fragmented memory buffers, the Scatter/Gather
feature provides high performance.
The KZPBA–CA comes with both AXP and Intel configuration utilities. These
configuration utilities provide the capability of changing settings on the board
flash EEROM without having to make physical changes to the host adapter
board. You can change settings such as host adapter SCSI termination and SCSI
Parity Checking.
1.2
KZPBA–CA Ultra Wide Single-Ended Host Adapter
The Ultra Wide Single-ended Host Adapter contains two 68-pin high density
connectors, one internally on the surface of the board and the other on the
external bulkhead, and one 50-pin connector. The internal connectors are used to
connect any internal SCSI drives to the PCI bus. The KZPBA–CA single-ended
Host Adapter is shown in Figure 3–1.
In a 16-bit (wide) SCSI bus, the KZPBA–CA can directly support up to 15 wide
single-ended SCSI devices (operating system dependent). Each of the two 68-pin
connectors can support up to 15 single-ended 16-bit SCSI devices or seven
single-ended 8-bit SCSI devices. The 50-pin connector can support up to seven
single-ended 8-bit devices.
You can use only internal or external SCSI connectors at any one time. The
KZPBA–CA does not support simultaneous use of both internal and external
connectors.

Configuration Guidelines
Before you install the KZPBA–CA host adapter in your computer, you need to become
familiar with the product, the configuration guidelines for the host adapter, and its SCSI
bus. This chapter includes installation guidelines, a description of single-ended SCSI
buses, and sample configurations.
NOTE
If you are familiar with configuration guidelines
and know the configuration that you are installing,
skip to Chapter 3 and begin by installing the host
adapter.
2.1
Configuration Guidelines
More than one KZPBA–CA Host Adapter can be installed in the same host
computer. The number of boards that can be installed is only limited by the
number of PCI slots available in the host computer. Unless a SCSI-bus converter
is used, only single-ended SCSI devices can be directly connected to the singleended host adapter. For external UltraSCSI device use, refer to Section 2.5 and to
the UltraSCSI Configuration Guidelines (EK–ULTRA–CG) for recommended
configurations; also, refer to our Web page at: http://www.storage.digital.com/.
Physical Configuration
The Personality Module resides in the BA356 storage shelf. The host adapter
connects directly to the Personality Module using a point-to point cable
connection.
Single-Ended SCSI Bus Configuration
The DS–BA356–XX storage shelf contains two single-ended SCSI buses that are
internally configured as a single bus. A maximum of seven 3½-inch half-height
8-bit or 16-bit SCSI devices in DIGITAL StorageWorks Building Blocks (SBBs)
can be attached to the bus. This bus can be split so that storage shelf can be
configured to have one 3-device bus configuration and one 4-device bus
configuration. This is useful when a specific device requires more than one slot
(such as a tape loader or solid state drive).
EK–KZPBA–UG. B01
2–1
KZPBA–CA PCI-to-UltraSCSI Host Adapter
SCSI ID Selection
The KZPBA–CA host adapter is assigned SCSI ID 7. For the SCSI devices
mounted in the storage shelf, the device address is determined by its physical
location in the storage shelf, with the slot number equating to the SCSI ID
number.
SCSI Bus Termination
For a single-ended bus connection, the single-ended bus is terminated at one end
by the KZPBA–CA adapter and at the other end by the StorageWork shelf
Personality Module
2.2
Configuration Topography
You can configure the host adapter to be in the middle or at the end of the SCSI
bus.
Configure the host adapter in the middle of the SCSI bus by using both internal
connectors, each connected to one or more internal SCSI devices.
When the host adapter is at one end of the bus, the bus is terminated at the host
adapter and at the last SCSI device. When the host adapter is in the middle of the
bus, the bus is terminated by the last SCSI device at each end of the bus.
2.2.1 SCSI Cable Selection
Always select high-quality SCSI cables to use in your system. Because singleended host adapters support UltraSCSI transfer rates, the use of high-quality
cabling is especially critical. Cables of a lesser quality can cause data corruption,
parity errors, and other problems.
Round external SCSI cables vary widely in quality and electrical characteristics.
Ascertain, from your cable supplier, that external cables meet SCSI-2 standards.
The following are some cable selection guidelines:
•
Use layered twisted pair cables with 25-wire pairs
•
Use cables that have a single-ended impedance range of 80-100ohms
•
Do not use cables shorter than 30 cm (11.8 inches) between any two SCSI
devices
2.2.2 SCSI Bus Lengths
The length of a SCSI bus segment is the cable distance between the two bus
terminators, with each terminator located at an end of the bus segment. The
length of the Single-ended SCSI bus should not exceed 1.5 meters when
operating in UltraSCSI mode, using internal connectors to internal devices. If
you are using an UltraSCSI DIGITAL StorageWorks enclosure, refer to the
2–2
EK–KZPBA–UG. B01
Chapter 2. Configuration Guidelines
UltraSCSI Configuration Guidelines for cable lengths. For Fast-10 SCSI
configurations with BA356 StorageWorks enclosures, the maximum cable length
is 2.0 meters.
2.3
SCSI Bus Termination
The integrity of the data written to or read from a SCSI device can be seriously
compromised due to signal reflections caused by an unbalanced SCSI bus. An
unbalanced bus is the result of an improperly terminated or unterminated bus.
Therefore, failure to terminate the bus properly can result in a system crash or
even worse, data corruption.
A balanced bus is achieved by properly installing bus terminators on the SCSI
bus in relation to the host adapter and the SCSI devices. SCSI bus termination
on the KZPBA–CA Host Adapter ultra wide single-ended board is established
using one of the utility programs included in the host adapter kit.
Proper bus termination involves supplying termination power onto the SCSI bus
and the strategic placement of terminators on the bus. The KZPBA–CA PCI-toUltraSCSI Host Adapter provides active termination power and is generally the
only source of termination power required on the bus. However, Digital
Equipment Corporation recommends that all devices on the SCSI bus supply
termination power to ensure that there is a sufficient level of power along the
entire bus. SCSI devices are protected by a diode or similar semiconductor to
prevent back flow of the termination power when more than one device supplies
this power.

3.3.1 Connecting Internal SCSI Devices
Refer to your SCSI device documentation if you want to install one or more
SCSI device inside the host computer. The internal device(s) must be singleended.
To connect an internal SCSI device to the KZPBA–CA host adapter, you will
need one, or both, of the following cables depending on the requirements of your
internal drive.
•
A 50-pin connector SCSI ribbon cable with a 50-pin header internal connector
to mate with the KZPBA–CA host adapter 50-pin connector
•
A 68-pin connector SCSI cable with a 68-pin header internal connector to
mate with the KZPBA–CA host adapter 68-pin connector
NOTE
If you are connecting more than one internal SCSI
drive to the KZPBA–CA host adapter, there must
be additional connectors on the cable to
accommodate the additional drives.
Follow these steps to install the internal SCSI ribbon cable:
1.
Insert the connector on one end of the SCSI cable into the connector on the
host adapter (see Figures 3–3 and 3–4).

NOTE
The colored stripe on one side of the ribbon cable
must be aligned with pin 1 on the host adapter
board. For all remaining connections on the SCSI
bus, make sure that the colored stripe edge of the
ribbon cable aligns with pin 1 on the SCSI device
connector. Pin 1 orientation is required so that all
the SCSI devices will work properly.
2.
Insert the last connector on the ribbon cable into the connector on the
internal SCSI device on the shelf (see Figure 3–5).
Figure 3–5 Connecting Ribbon Cable to Internal SCSI Device
3.
To connect a second internal SCSI device, plug the middle ribbon cable
connector into the connector on the second internal device (see Figure 3–6)
maintaining the pin orientation.
NOTE
Refer to your host computer documentation for
more information describing how to connect the
adapter to internal devices.

Figure 3–6 Connecting Ribbon Cable to a Second Internal SCSI Device
4.
To connect three or more internal SCSI devices to the SCSI bus, the ribbon
cable must have enough connectors to accommodate all the devices. Plug the
connectors into the SCSI devices maintaining the pin-1 orientation.
5.
If you are using both internal connectors on the host adapter, proceed in the
same fashion as above for the other cable.
3.3.2 Connecting External SCSI Devices
The preferred cabling method is a point-to-point cable connection from the
KZPBA–CA Host Adapter to the DS–BA356–XX. Up to fifteen wide SCSI
devices can be supported externally to the KZPBA–CA through carefully cabled
topologies. See the UltraSCSI Configuration Guide for more details.
The KZPBA–CA does not support daisy-chained configurations with the
KZPBA–CA in the middle of the SCSI bus attached by the external connector.
The external connector on the single-ended version of the module is a 68-pin
connector. The external connector is keyed so that it can be plugged in only one
way making the pin-1 orientation automatically correct.
Follow these steps to connect an external SCSI device housed within a
DS–BA356–XX shelf:
1.
3–8
Attach one end of the cable to the KZPBA–CA host adapter (see Figure 3-7).

Setting SCSI Bus Termination
A set of terminating resistors must be either physically installed or software
enabled on the first and last physical device on the SCSI bus. You may have to
change the termination on the host adapter module and on some of the SCSI
devices.
1.
Determine which two SCSI devices (including the host adapter) are at each
end of the SCSI bus. Install or enable termination on these two devices.
2.
Disable termination on all other devices on the SCSI bus.
3.
If one 8-bit and one 16-bit connector are used in a single-ended SCSI bus
application, the upper 8 bits of the default termination setting must be
terminated using the flash EEROM Configuration Utility (see Chapter 4).
The following paragraphs contain more information about device termination.
3.4.1 SCSI Device Termination
Refer to the SCSI device manufacturer’s documentation to determine how a
particular device’s termination is enabled or disabled.
3–10
EK–KZPBA–UG. B01
Chapter 3. Installing the KZPBA–CA Adapter
3.4.2 Host Adapter Termination
Termination on the KZPBA–CA single-ended host adapter module is software
controlled and its default is auto enabled. If you are using only one internal
connector or external connector, the default does not have to be changed.
Single-Ended Module
On the single-ended module, if you are using both internal connectors, the
default termination must be changed. To do this, first complete the installation,
then refer to the flash EEROM Configuration Utility (see Chapter 4).
3.4.3 Possible Termination Configurations
Internal Devices only
Internal devices can only be used with the KZPBA–CA Single-ended Host
Adapter. How you terminate the devices and the host adapter depends on
whether one or both of the module-edge connectors are used.
•
If only one of the board-edge connectors is used, you must terminate the last
internal device on the SCSI bus and disable termination on the other devices.
The host adapter is already terminated by default and this setting should not be
changed (see Figure 3–9).
EK–KZPBA–UG. B01
3–11
KZPBA–CA PCI-to-UltraSCSI Host Adaptaer
Figure 3–9 Single Internal SCSI Bus
CAUTION
A KZPBA–CA host adapter does not support the
simultaneous use of both internal and external
connectors. If it is necessary to attach both
internal and external SCSI devices, a second
KZPBA–CA Host Adapter can be installed in the
same host computer.
•
3–12
If you attach internal SCSI devices to both of the internal connectors on the
host adapter, you must terminate the last SCSI device on each internal cable
and disable termination on the other devices (see Figure 3–10). Because one
device is attached to the 8-bit, 50-pin connector and the other attached to the
16-bit, 68-pin connector, the host adapter termination must be changed so
that the high order bits are on. This is necessary to maintain the balance in
the SCSI bus. To do this refer to the flash EEROM Configuration Utility
(refer to Chapter 4).
EK–KZPBA–UG. B01
Chapter 3. Installing the KZPBA–CA Adapter
Figure 3–10 Two Internal SCSI Buses
External Devices Only
When only external SCSI devices are connected to the host adapter, the last
external device must be terminated and all other devices must have their
termination removed. DIGITAL StorageWorks simplifies this by terminating the
end of the bus within the storage enclosure. For example, as shown in
Figure 3-11, the end of the bus is terminated by the Personality Module. The host
adapter is already terminated by default and this setting should not be changed.

SCSI Device Identification (SCSI ID) and Arbitration
Every device on a SCSI bus, including the Host Adapter, must be uniquely
identified with a SCSI ID. The SCSI ID serves two purposes:
•
It provides a unique identification to each device on the SCSI bus
•
It establishes the device’s priority on the bus during the arbitration phase
Setting the SCSI ID is a two-step process:
1.
Determine the SCSI ID number that is to be assigned to each drive on the
SCSI bus. To set the ID for the various devices that are going to be on the
bus, read the manufacturer’s documentation for each device to determine the
appropriate switch or jumper settings.
2.
Change SCSI IDs as necessary so that priority arbitration is as desired and
that no two devices have the same ID. The host adapter should be assigned
ID 7.
If more than one host adapter is installed, each host adapter has a separate SCSI
bus associated with it. The second SCSI bus can use the same ID numbers as
assigned to the first bus even though different devices are used.
3–14
EK–KZPBA–UG. B01
Chapter 3. Installing the KZPBA–CA Adapter
SCSI Bus Priority Arbitration
SCSI bus priority arbitration is based on the SCSI ID of the arbitrating device.
Priority arbitration is established from highest to lowest. The host adapter is
normally assigned SCSI ID 7.
For example, in the following priority arbitration scheme, SCSI ID 7 has the
highest priority and SCSI ID 8 has the lowest priority:
SCSI ID 7-6-5-3-2-1-0-15-14-13-11-9-8

EEROM Configuration Utility (Alpha-Systems)
This chapter describes the EEROM configuration utility for the KZPBA-CA adapter in
Alpha- systems.
4.1
EEROM Parameter Settings
The KZPBA-CA host adapter ships with factory default EEROM parameters that
determine how the host adapter board operates and interacts with connected
devices. The default EEROM parameter settings were chosen to provide the best
performance optimization for most system configurations. If you want to change
the parameter settings, refer to Appendix B at the end of this guide.
The KZPBA-CA host adapter also ships with a floppy diskette containing the
ISP1020/1040 EEROM Configuration Utility for Alpha AXP which you can use
to change parameter settings. A description of the EEROM configuration utility
and how to use it to change parameter settings is presented in the following
section.
4.2
The EEROM Configuration Utility
The ISP1020/1040 EEROM Configuration Utility for Alpha AXP provides you
with a means to access and change the host specific and device specific
parameters stored in EEROM on the KZPBA-CA host adapter. It runs from the
ARC console of Alpha AXP systems (see the Release Note supplied with the
KZPBA-CA for the minimum version level required.)
The utility displays on a VGA monitor
The major steps required to change EEROM settings include:
•
Setting terminal, if displaying on a terminal
•
Starting the utility
•
Changing the appropriate host adapter or device-specific parameters

sensitive to an imperfect SCSI bus.
Set to 0 to disable the
active negation.
Data DMA Burst
Enable
1
When set to 1, performs burst
transfers on the data DMA channel.
When set to 0, data is
transferred in
nonburst mode with
each cycle initiated by
a new address phase.
Command DMA
Burst Enable
1
When set to 1, performs burst
transfers on the data DMA channel.
When set to 0, data is
transferred in
nonburst mode with
each cycle initiated by
a new address phase.
Tag Aging
8
Insures tagged commands are not
lost in the target device. Tag aging
is a backup to the time-out
mechanism.
0–255 cycles, drive
dependent.
Low
Termination
Enable
1
Provides termination to the loworder eight bits.
Set to 0 if termination
not required on the
board. See
termination section of
this guide for
termination
requirements.

time-out values
available.
Maximum
Queue Depth
256
Specifies the maximum number of
outstanding commands issued to
each SCSI target. When the
number is reached, new commands
are returned with Queue Full
Status.
0 to 64K commands
FIFO 128
Threshold
Enable
0
Enables or disables the FIFO burst
length of 128 bytes.
Set to 1 to enable the
FIFO 128 Threshold.
Fast RAM

Disable
0
Allows the BIOS code to issue a
SCSI reset during BIOS
initialization.
Set to 1 to prevent
the BIOS code from
issuing a SCSI reset
during BIOS
initialization.
Enable Auto
Termination
1
Enables or disables the adapter’s
auto termination. Auto termination
circuitry senses if proper SCSI bus
termination is present and
terminates the bus, if not.
Set to 0 to disable
auto termination.

(KZPBA-CA to Device Interaction)
Parameter
Default
Re-negotiate-onError
1
Set to 1, enables re-negotiation
for synchronous and wide data
transfers (if wide transfers are
enabled) after a hard reset,
power cycle, or a bus device
reset.
Set to 0 to disable renegotiation on error.
Stop Queue on
Check Condition
0
When a command is returned
with a Check Condition status,
new commands are issued by
the KZPBA-CA to the device.
Set to 1 to prevent the
KZPBA-CA from issuing
new commands when a
command is returned
with a Check-Condition
status.
Auto Request
Sense
1
When a command is returned
with Check Condition status the
KZPBA-CA issues a request
command to determine cause.
Set to 0 to disable the
request command. The
computer’s OS must be
able to correct the
problem and notify the
adapter when it can
continue issuing
commands.
Tagged Queuing
1
Allows the drive to queue
multiple commands when
enabled.
Set to 0 to disable tag
queuing.
Synchronous
Data Transfers
1
Specifies the number of clock
cycles in the data hold period for
synchronous data transfers.
Set to 0 to disable
synchronous data
transfers.
Wide Data
Transfers
1
Sets the drive to support wide
SCSI data transfers.
Set to 0 to disable widedata transfers.
Device Enable
1
The system BIOS and drivers
recognize the drives attached to
the KZPBA-CA.
Set to 0 for the BIOS
and drivers to ignore the
drives.
Parity Checking
1
The KZPBA-CA checks for odd
parity on data received from the
SCSI bus, the received parity is
passed to the SCSI FIFO.
When set to 0, the
KZPBA-CA does not
check for odd parity on
data received from the
SCSI bus and odd parity
is generated for the
SCSI FIFO.

communications link when the
KZPBA-CA issues a command. The
KZPBA-CA must re-establish the
link (through a reconnect) when it is
ready to continue executing.
When set to 0,
disconnects are not
allowed.
Execution
Throttle
16
Specifies the number of tagged
commands the KZPBA-CA can send
to the drive until the command
queue is full. When the queue is full,
the KZPBA-CA waits until there are
no outstanding commands before
sending the tagged commands.
0–255 commands.
Specifies the minimum REQ/ACK
period (4-ns increments) for a
synchronous data transfer.
25–100 4 ns
increments.
