adapter designed for high-end systems. The function and performance are
derived from the ISP2312 chip, making this Host Bus Adapter a leading-edge
host adapter.
The DS4000 Adapter uses a multi-mode shortwave optical interface for distances
up to 500 meters when operating at 1 Gbps and 300 meters when operating at 2
Gbps. It supports data transfer rates up to 200 MB per second half-duplex and
400 MB per second full-duplex on optical interfaces.
Attention: Multi-mode optical cabling is available in either a 50 micron or 62.5
micron core with a cladding of 125 microns. The FC2-133 Adapter requires
use of 50 micron optical cabling.

The ISP2312 chip combines a reduced instruction set computer (RISC)
processor, a Fibre Channel protocol manager (FPM) with one 2 GB Fibre
Channel transceiver, and a peripheral component interconnect (PCI) or
peripheral component interconnect-extended (PCI-X) local bus interface in a
single-chip solution. The IBM TotalStorage DS4000 133 Host Bus Adapter
supports all Fibre Channel (FC) peripheral devices that support private-loop
direct attach (PLDA) and fabric-loop attach (FLA).
The DS4000 FC2-133 Adapter has the following features:
Based on the QLogic QLA2340 Fibre Channel HBA
Compliance with Intel PCI Local Bus version 2.2 specification
