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
QCP/QSB23xx HBA unless otherwise noted. The QCP23xx HBAs are all 64-bit
PCI to Fibre Channel optical media. The QSB23xx HBAs are all 64-bit SBus to Fibre
Channel optical media.
■ QCP2330 (cPCI to single-channel)
■ QCP2332 (cPCI to dual-channel)
■ QCP2340 (cPCI to single-channel)
■ QCP2342 (cPCI to dual-channel)
■ QSB2340 (SBus to single-channel)
■ QSB2342 (SBus to dual-channel)
First, install the QCP/QSB23xx HBA according to the directions in the appropriate
hardware installation section. Second, install the Solaris driver. If the device
attached to the HBA is the boot device, install the FCode.

General Description
Thank you for selecting the QCP/QSB23xx Fibre Channel (FC) HBA. The
QCP/QSB23xx HBA is a single- or dual-channel, intelligent, high-performance,
DMA bus master host adapter designed for high-end systems. The intelligence and
performance are derived from the ISP23xx controller, making the QCP/QSB23xx
HBA a leading-edge host adapter. The ISP23xx combines a powerful RISC
processor and a fibre protocol module (FPM) with one 2-Gb Fibre Channel
transceiver in a single-chip solution. The QCP/QSB23xx HBA supports all FC
peripherals that support private loop direct attach (PLDA) and fabric loop attach
(FLA). Installation of the QCP/QSB23xx board 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.
Two-gigabit Fibre Channel supports data transfer rates of 200 MBps half-duplex
and 400 MBps full-duplex. The QCP/QSB23xx HBA uses a multimode optical
