Single and Dual Port HBA Features

The single and dual port HBAs consist of a single-slot PCI-X 2.0 bus expansion board that interfaces a 64-bit PCI bus to one or two Fibre Channel (FC) optical media busses. The single and dual port HBAs support 32-bit and 64-bit PCI transfers as a master bus during direct memory access (DMA) transfers and 16-bit transfers as a slave during parallel input/output (PIO) operations, as well as PCI-X 1.0 and 2.0 transactions. The channels of the single and dual port HBAs can act as either initiators or targets. In the dual-port HBA, the two channels operate independently and each supports a separate bus that operates at 4.25 Gbits per second. The single and dual port HBAs are also backward compatible with 2.125-Gbit-per-second and 1.0625-Gbit-per-second busses.

One or two Small Form Factor (SFF) optical transceivers are used to connect to the external FC busses. One Helios FC Controller chip is used to support one or two independent FC busses.

See TABLE 1-1 for a list of the single and dual port HBA features.

Minimum System Hardware Requirements

Your system must have an available PCI or PCI-X 64-bit slot to support these single and dual port HBAs.

This product uses +3.3V signaling only, and is incompatible with +5.0-V signaling PCI slots.

Supported Operating Systems

You can use the single and dual port HBAs with the following operating systems:

Solaris 8, 9, and 10 Operating Systems

To use the single and dual port HBAs with these operating systems, you must use the Sun driver as described in Solaris 8, 9, and 10 Operating System Requirements.

Red Hat Enterprise Linux and SuSE Linux Enterprise Server Operating Systems

To use the single and dual port HBAs with these operating systems, you must use the Emulex driver as described in Red Hat Enterprise Linux and SuSE Linux Enterprise Server Operating System Requirements.

Windows 2000 and Windows Server 2003 Operating Systems

To use the single and dual port HBAs with this OS, you must use the Emulex driver as described in Windows 2000 and Windows Server 2003 Operating System Requirements.
