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.
