1. c:\issa\update\driver
which will contain the device-driver software. If asked to load
device-driver software from the CD-ROM, you must instead
load the software from this directory.
2. c:\issa\update\rsm
which will contain the event logger and Remote System
Management (RSM) software. If asked to load the event
logger from the CD-ROM, you must instead load the code from
this directory.
3. c:\issa\update\ssaflash
which will contain the SSA-adapter microcode.
Refer to Chapter 5 of this manual for details about downloading
the SSA-disk-drive microcode.
For NetWare, download the Host Software, Adapter Microcode and
RSM for NetWare packages. These self-extracting packages allow
you to create the required diskettes or data directories.

viii IBM Advanced SerialRAID/X Adapter: Installation Guide

Chapter 1. Overview
The IBM Advanced SerialRAID/X Adapter allows you to connect SSA disk drives to
certain system units with a Peripheral Component Interconnect (PCI) bus. These disk
drives can be accessed individually or they can be configured in RAID arrays. RAID
(Redundant Array of Independent Disks) provides a way to spread stored data among a
number of hard disk drives attached to a host system. A PCI bus provides high-speed
data transfer. A Fast-Write Cache feature further improves the performance of the
adapter.
You can create, control, and manage a RAID configuration with supporting host
software. The IBM Advanced SerialRAID/X Adapter supports data rates up to 40 MB
per second on each SSA interface; and data rates up to 120 MB per second on the PCI
bus. You can install up to 6 IBM Advanced SerialRAID/X Adapters in some host
systems, depending on the system unit.
Serial Storage Architecture (SSA) is a high-performance serial-interconnect technology
used to connect I/O devices and host adapters. SSA is an open standard, and SSA
specifications have been approved by the SSA Industry Association and are in the
process of being approved as an ANSI standard through the ANSI X3T10.1
subcommittee.
Handling the Adapter
Attention: Static electricity can damage this adapter and your system unit. To avoid
damage, keep your adapter in its protective bag until you are ready to install. To reduce
the possibility of electrostatic discharge, follow the precautions listed below.
Electrostatic Discharge Protection
To prevent electrostatic discharge:
vAlways wear an electrostatic discharge (ESD) wrist strap correctly connected to an
ESD ground bracket when you handle the adapter. This prevents possible damage to
the adapter and decreases any possible impact to system operations.
vLimit your movement. Movement can cause static electricity to build up around you.
vHandle the adapter carefully and by the edges.
vDo not touch any exposed printed circuitry.
vPrevent other people from touching the components or the adapter card.
vWhen you are installing the adapter, touch the static-protective package containing
the adapter to a metal expansion-slot screw or other unpainted metal surface on the
computer, for at least 2 seconds. (This drains static electricity from the package and
from your body.)
vWhen possible, remove the adapter and install it directly into the computer without
setting it down. If this is not possible, place the adapter, component side up, on the
static-protective bag on a flat surface until the adapter is installed.
vDo not place the adapter on the computer cover or on a metal table.

SSA Connectors
The IBM Advanced SerialRAID/X Adapter has four external connectors, arranged in two
pairs. Up to 48 SSA disk drives can be connected in a loop between each pair of
external connectors. If you are not using RAID-0 arrays you can connect up to two IBM
Advanced SerialRAID/X Adapters in the SSA loop.
“Appendix A. Connecting SSA Devices to the Adapter”on page 31 provides more
information about SSA loops. Figure 1 shows the card.
Adapter Card Lights
On the IBM Advanced SerialRAID/X Adapter card, there is a light next to the pair of
SSA connectors (port 1 and port 2) for each SSA loop.
vThe light is on continuously when power is turned on to the adapter and both ports
for that loop are operational; that is, the devices connected next to the adapter in the
loop have power turned on to them, are connected correctly to the adapter, and are
operational.

vThe light flashes continuously if one of the ports is not operational. That occurs when
the cable to that port is not connected correctly or the device connected next to the
adapter in the loop is not operational.
vThe light is off if both ports are not operational.
Summary of Installation Procedures
Installing the adapter consists of the following steps:
vTaking an inventory of all pieces necessary for installation
vInstalling the adapter
vConnecting the SSA disk drives
vInstalling the SSA device drivers, software, and any required microcode.

Chapter 2. Preparing for Installation
This section shows you the items you need to install the IBM Advanced SerialRAID/X
Adapter. It also describes the cable requirements.
Inventory
To install the IBM Advanced SerialRAID/X Adapter, you need:
vThe adapter.
vThe diskettes that are supplied with the adapter.
vThe CD-ROM that is supplied with the adapter contains the device-driver software,
the event logger, the Remote Systems Management (RSM), the SSA-disk-drive
microcode, the SSA-adapter microcode, and the product manuals in Adobe Acrobat
PDF format.
vYour system unit documentation.
vYour operating system documentation.
vA flat-blade screwdriver.
vAn electrostatic discharge (ESD) kit.
To connect SSA disk drives to the IBM Advanced SerialRAID/X Adapter, you need:
vExternal SSA cables.
vSSA Screwdriver Part Number 32H7059.
vFibre-Optic Extenders, if you are using fibre optic cables. (The extenders are
supplied in pairs as a feature of the unit in which the SSA disk drives are installed,
for example, the 7133 disk system.)
vThe plan for your SSA subsystem configuration.
vThe documentation for the unit in which the SSA disk drives are installed.
Determining Your Cable Requirements
There are two types of SSA cable:
vCopper cables with conventional connectors at each end. These enable you to
connect SSA nodes at distances up to 25 m (82 feet).
vFibre-optic cables. These enable you to connect two SSA nodes at distances up to
10 km (32800 feet) in single-mode operation. These require the use of Fibre-Optic
Extenders; these are supplied in pairs as a feature of the unit in which the SSA disk
drives are installed, for example, the 7133 disk system.
The number and type of cables that you need and their lengths should have been
decided at the time that your SSA subsystem was ordered. If the configuration plan that
was created then is not available to you, use the sample configuration information that
is provided in the documentation for the unit in which the SSA disk drives are installed.
“Appendix A. Connecting SSA Devices to the Adapter”on page 31 provides some
general information about SSA configurations.
