Optical Fibre Option

The QLogic adapter also supports connection to the switch by means of optical fibres through optical media converters such as the EMCORE™ QT2400. Not all switches support these types of convertors. For more information on the EMCORE convertor, see www.emcore.com.

Intel® and Zarlink™ also offer optical cable solutions. See www.intel.com and www.zarlink.com for more information.

Configuring the BIOS

To achieve the best performance with QLogic adapters, you need to configure your BIOS with specific settings. The BIOS settings, which are stored in non-volatile memory, contain certain parameters characterizing the system. These parameters may include date and time, configuration settings, and information about the installed hardware.

This setting is required:

„Advanced Configuration and Power Interface (ACPI) BIOS option must be enabled.

For more information, see “Enable Advanced Configuration and Power Interface (ACPI)” on page A-2and the Troubleshooting section of the QLogic HCA and QLogic OFED Software Users Guide.

Some other BIOS settings can be adjusted for better adapter performance. See “Adapter and Other Settings” on page 7-1.

For specific instructions about BIOS settings, follow the hardware documentation that came with your system.

NOTE:

The x86 Page Attribute Table (PAT) mechanism that allocates write-combining (WC) mappings for the PIO buffers has been added and is now the default. This was previously a BIOS setting. For more information, see “Write Combining” on page B-1.
