Chapter 1. Preparing and installing the IBM TotalStorage
DS4000 FC2-133 Host Bus Adapter
This chapter contains instructions for preparing and installing the IBM TotalStorage
DS4000 FC2-133 Host Bus Adapter and describes the adapter components. The
IBM TotalStorage DS4000 FC2-133 Host Bus Adapter is referred to throughout this
book as the FC2-133 Adapter.

Overview

The IBM TotalStorage DS4000 FC2-133 Host Bus Adapter is a 2 gbps
high-performance, direct memory access (DMA), bus master, Fibre Channel host
adapter designed for high-end systems. The function and performance are derived
from the ISP2312 chip (see Figure 3 on page 4), making this IBM TotalStorage
DS4000 FC2-133 Host Bus Adapter a leading-edge host adapter.
The ISP2312 chip combines a powerful, reduced instruction set computer (RISC)
processor, a Fibre Channel protocol manager (FPM) with one 2 GB Fibre Channel
transceiver, and a peripheral component interconnect (PCI) or peripheral component
interconnect-extended (PCI-X) local bus interface in a single-chip solution. The IBM
TotalStorage DS4000 FC2-133 Host Bus Adapter supports all Fibre Channel (FC)
peripheral devices that support private-loop direct attach (PLDA) and fabric-loop
attach (FLA).
The IBM TotalStorage DS4000 FC2-133 Host Bus Adapter connects the following:
v Mainframe computers
v Super computers
v Workstations
v Storage devices
v Servers

Fibre Channel defined

Fibre Channel technology is outlined in the SCSI-3 Fibre Channel Protocol
(SCSI-FCP) standard. Fibre Channel is a high-speed data transport technology
used for mass storage and networking.
Using a Fibre Channel Arbitrated loop (FC-AL), 126 Fibre Channel devices can be
supported, compared to 15 small computer system interface (SCSI) devices with
Ultra SCSI.
The FC2-133 Adapter uses a multimode shortwave optical interface for distances up
to 500 meters when operating at 1 gbps and 300 meters when operating at 2 gbps.
The FC2-133 Adapter is a 2 gbps Fibre Channel device that supports data transfer
rates up to 200 MB per second half-duplex and 400 MB per second full-duplex on
optical interfaces.
