How to Use this Guide

The SANblade™ QLogic® host bus adapters (HBAs) supported in this document are described in the following paragraphs:

■QLA®4010 (single channel, full-height bracket, optical media)

■QLA®4010C (single channel, full-height bracket, copper media)

The QLA4010 HBA is 32/64-bit, 33/66/133-MHz PCI-X to iSCSI over Gigabit Ethernet on optical media. The QLA4010C HBA is 32/64-bit, 33/66/133-MHz PCI-X to iSCSI over Gigabit Ethernet on twisted-pair copper media.

This guide contains installation instructions for the hardware (QLA4010/4010C HBA) supported software drivers, and BIOS configuration utility (Fast!UTIL). Install these components in the following order:

1.Install the QLA4010/4010C HBA in your PC.

2.Install the software driver according to the directions in the appropriate section.

NOTE: For a Solaris SPARC system the driver must be installed before installation of the HBA.

3.Optionally, you can customize the QLA4010/4010C HBA and its attached devices using the Fast!UTIL BIOS utility. See the associated readme.txt file for detailed instructions.

General Description

The QLA4010/4010C is an iSCSI HBA that provides PCI connectivity to SCSI using the iSCSI protocol. This release of the QLA4010/4010C HBA implements draft 20 of the IETF iSCSI standard, which creates a new industry standard SAN technology based on internet protocols: TCP/IP. Any updates to the standard 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 QLA4010/4010C 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 QLA4010/4010C HBA handles complete SCSI transactions, iSCSI, TCP/IP, and Ethernet.
