How to Use this Guide
The SANblade™ QLogic host bus adapters (HBAs) supported in this document are
described in the following paragraphs. They are collectively referred to as the
QLA2342/2342L HBA unless otherwise noted.
QLA2342 (dual channel, full-height bracket, optical media)
■
QLA2342L (dual channel, low-profile bracket, optical media)
■
The QLA2342/2342L HBA are 64-bit, 133-MHz PCI-X to Fibre Channel optical
media.
First, install the QLA2342/2342L HBA according to the directions in the appropriate
hardware installation section. Secondly, install the software driver according the
directions in the associated readme.txt file.

General Description
Thank you for selecting the QLA2342/2342L Fibre Channel (FC) HBA. The
QLA2342/2342L HBA is an intelligent, high-performance, DMA bus master host
adapter designed for high-end systems. The intelligence and performance are
derived from the ISP23xx chips, making the QLA2342/2342L HBA a leading-edge
host adapter. The ISP23xx combines a powerful RISC processor, a Fibre Channel
protocol manager (FPM) with one or more 2-Gb Fibre Channel transceivers, and a
peripheral component interconnect-extended (PCI-X) local bus interface in a
single-chip solution. The QLA2342/2342L HBA supports all FC peripherals that
support private loop direct attach (PLDA) and fabric loop attach (FLA). Installation
of the QLA2342/2342L HBA is quick and easy.

What is Fibre Channel?
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. It connects mainframes, super computers,
workstations, storage devices, and servers.
Fibre Channel supports data transfer rates up to 200 MBps half-duplex and
400 MBps full-duplex on copper and optical interfaces. The QLA2342/2342L HBAs
use a multimode optical interface for intermediate distances (less than 500 meters
at the data rate of 1 Gbps; less than 300 meters at the data rate of 2 Gbps).
