Chapter 1
Introduction
The Compaq KZPEA adapter is a 64-bit/66 MHz PCI, dual-channel Ultra3 SCSI
controller that interfaces directly with a Peripheral Component Interface (PCI)
local bus. It supports both external Compaq StorageWorks or internal storage
devices on AlphaServers and workstations, per LVD Ultra3 SCSI channels. The
adapter supports no more than 15 SCSI drives per channel or 30 SCSI drives
per adapter. The SCSI buses can be connected to disk drives, CD-ROM drives,
tape drives, and other SCSI devices. More than one host adapter can be
installed in the same host computer.
The SCSI processor negotiates with each device on the SCSI bus to establish the
maximum data transfer rate, based on the SCSI specifications, between the host
adapter and the device. It also automates SCSI command processing and
significantly reduces the number of interrupts and command overhead. The
host adapter supports multi-threaded I/O operations, thereby allowing
simultaneous operations on multiple SCSI targets or Logical Unit Numbers
(LUNs). In systems with multiple targets, the Disconnect/Reconnect feature
optimizes SCSI bus usage. In systems that support fragmented memory
buffers, the Scatter/Gather feature provides high performance.

Introduction 1-3
The KZPEA adapter has the following features:
•Self-resetting term power.
•Multiple Logical Unit Numbers (LUNs) for robotics control commands.
•Onboard NVRAM and SCSI Utility.
•PCI 2.2 compliant.
•Supports universal 32-bit PCI and universal 64-bit PCI.
•Supports 33 MHz and 66 MHz PCI.
•Contains one 50-pin narrow SCSI internal connector to support legacy
devices such as CD-ROMs. This cable supports up to seven devices.
•Automatically detects and communicates with Wide Ultra3, Wide Ultra2,
Wide Ultra SCSI-3, Fast Wide SCSI-2, or Fast SCSI-2 devices.
•Supports Wide Ultra3 SCSI, a 16-bit 40 MHz bus that provides a 160
Mbytes/sec data transfer rate.
•Contains two 68-pin HD wide SCSI internal connectors that support Wide
Ultra3 SCSI, Wide Ultra2 SCSI, Wide Ultra SCSI-3, and Fast SCSI-2
devices.
•Contains two Very High-Density Cable Interconnect (VHDCI) external
connectors that support Wide Ultra3 SCSI, Wide Ultra2 SCSI, Wide Ultra
SCSI-3, and Fast Wide SCSI-2 devices.
NOTE: Double Transition (DT) clocking doubles data throughput to 160
megabytes per second. This is done by sending two pieces of data per
clock pulse instead of one, thereby doubling the throughput without
increasing the processor’s clock speed.
NOTE: Devices may be connected to the 50-pin connector or Channel 1/A
LVDs, but not to both.

Introduction 1-5
1.3 Wide Ultra3 SCSI Support
The KZPEA adapter provides 64-bit PCI bus master operation and SCSI
data transfer rates of up to 160 MB/s, provided all components are Wide
Ultra3 capable.
This combination allows high throughput in many network application
environments, including resource-sharing, database-servicing, and high-
performance backup solutions.
The adapter also supports tagged command queuing, which allows SCSI hard
drives to queue and sort multiple commands, then execute those commands
simultaneously.
The KZPEA adapter complies with ANSI SCSI-3 standards, supporting Wide
Ultra3 SCSI, Wide Ultra2 SCSI, Wide-Ultra SCSI-3, Fast-Wide SCSI-2, and
Fast-SCSI-2 devices. The KZPEA adapter can support several different SCSI
devices at one time.
The KZPEA adapter interface to the server processor is the PCI local bus. The
PCI bus is a high-performance, 64-bit bus with multiplexed address and data
lines. The PCI bus provides a high-speed (up to 528 MB/s) path between the
system unit and peripherals. Peripheral devices, such as Wide Ultra3 SCSI
adapters, benefit the most from the high I/O performance of the PCI bus.
The KZPEA adapter is compatible in a 32-bit/33 MHz, 64-bit/33 MHz, or
64-bit/66 MHz PCI slot.
The 64-Bit/66 MHz Wide Ultra3 SCSI adapter is a PCI bus master device and
conforms to Rev. 2.1 and 2.2 of the PCI Local Bus Specification.

1-6 KZPEA User’s Guide
1.3.1 SCSI Channel Assignments
SCSI channel 1/A and SCSI channel 2/B of the KZPEA adapter each support
one external VHDCI connector or internal 68-pin HD SCSI connector. SCSI
channel 1/A also has a 50-pin SCSI connector for CD-ROMs and tape support.
Only a single cable (internal or external) may be attached to each channel at a
time.
CAUTION: Do not connect SCSI cables to the internal connector and external
connectors at the same time. Only the external VHDCI connector or
the internal 68-pin connector is supported.
1.3.2 SCSI IDs
The KZPEA adapter contains two SCSI buses (SCSI channel 1/A and SCSI
channel 2/B) that support up to 15 peripherals each. Each SCSI bus has both
an internal and an external connector. The peripherals on each bus must have
a unique SCSI ID ranging from 6 to 0, then 15 to 8, with 6 being the highest
priority and 8 being the lowest priority. SCSI IDs on all peripherals must be
either set manually with switches or jumpers on the device itself, or set
automatically by Compaq products that support warm-swappable drives. The
SCSI IDs determine the priority of the peripheral device when it attempts to
access the SCSI bus. Your AlphaServer or Alpha workstation assigns the SCSI
adapter to the highest priority by setting the ID of the adapter to 7.

Introduction 1-7
1.3.3 Multiple Adapter Installation
The following considerations apply when you install more than one KZPEA
adapter:
•Each adapter has two independent SCSI channels. Each channel supports
up to 15 drives.
•Each SCSI channel has its own set of unique SCSI IDs (from 0 to 6 and 8
to 15). Each drive on a bus must be assigned its own unique ID.
1.3.4 SCSI Termination
Both SCSI buses require termination at both ends of the bus to prevent signal
degradation. The KZPEA adapter supplies the termination power at the
adapter end of the SCSI bus.
To obtain Ultra3 and Ultra2 performance, the bus must have multi-mode or
LVD-only terminators. Ultra and Fast-Wide SCSI are SE and have multi-mode
or SE termination.
CAUTION: To prevent error messages, an integrated SCSI controller on the
system board of an AlphaServer or workstation must be terminated
at all times. Mid-bus configurations are not supported.
External SCSI buses must also be terminated. This termination is supplied in
Compaq internal and external storage systems. Individual SCSI devices in
Compaq storage systems should not contain bus termination.

1.3.5 SCSI Cables
Cables are provided with most Compaq server products that require cabling. If
you find that you need an additional cable or that one was not provided with
your server product, you can order the necessary cables from your local Compaq
Reseller or authorized Compaq Service Provider. See Table 1-2 for external
cable part numbers.

1.3.6 SCSI Cable Connectors
To identify the various SCSI cables required for installing a KZPEA adapter in
various configurations of Compaq AlphaServers and workstations, see Figure

➊External 68-pin wide SCSI connector (Not used on KZPEA)
➋External VHDCI SCSI connector
➌Internal 68-pin HD SCSI connector
Keep these characteristics of SCSI cables in mind:
•External VHDCI cables are round and have thumbscrews on the connectors.
These connector heads are smaller than the 68-pin internal wide SCSI
connector heads.
•Internal SCSI cables are flat ribbon cables with push-on connectors.
•Internal 68-pin wide SCSI ribbon cables (Wide-Ultra SCSI-3 and Fast-Wide
SCSI-2) are narrower than 50-pin SCSI (Fast-SCSI-2) cables.
•Compaq SCSI cables are keyed so they cannot be installed incorrectly.
