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
QLA40xx HBA unless otherwise noted.
■ QLA4000 (single channel, full-height bracket, optical media)
■ QLA4000C (single channel, full-height bracket, copper media)
The QLA4000 HBA is 32/64-bit, 33/66-MHz iSCSI to Fibre Channel to optical media.
The QLA4000C HBA is 32/64-bit, 33/66-MHz iSCSI to Fibre Channel to copper
media.
This guide contains installation instructions for the hardware (QLA40xx HBA),
supported software drivers, and the SANblade Control iX GUI. Install these
components in the following order:
1. Install the QLA40xx HBA in your PC.
2. Install the software driver according to the directions in the appropriate section.
3. Install the SANblade Control iX GUI.
NOTE: If you are installing the QLA40xx HBA in Solaris SPARC system, install
the Solaris driver before installing the QLA40xx HBA.

General Description
The QLA40xx is an iSCSI HBA that provides PCI connectivity to SCSI using iSCSI
protocol. This release of the QLA40xx HBA implements draft 0.20 of the IETF iSCSI
standard, which creates a new industry standard SAN technology based on internet
protocols: TCP/IP. Updates to later iSCSI drafts will be available for downloads to
the HBA. iSCSI enables new IP-based SANs, which are similar to Fibre Channel
SANs, as well as a new set of storage applications, for example, remote storage.
The QLA40xx HBA implements the complete protocol stack, including TCP/IP, on
the HBA and off-loads the host of any I/O protocol processing. Off-loading the host
frees the system to perform other tasks and deliver optimum total system
performance. The QLA40xx HBA handles complete SCSI transactions, iSCSI,
TCP/IP, and Ethernet.
