 Chapter 1. Hardware overview
The IBM
 FAStT Host Adapter is a high-performance, direct memory access
(DMA), bus-master, host adapter designed for high-end systems. The function and
performance are derived from the ISP2200A chip, making this FAStT Host Adapter
a leading-edge host adapter.
The ISP2200A chip combines a powerful RISC processor, a Fibre Channel protocol
manager (FPM) with gigabit transceivers, and a 64-bit peripheral component
interconnect (PCI) local bus interface in a single-chip solution. The IBM FAStT
Host Adapter supports all Fibre Channel (FC) peripheral devices that support
private-loop direct attach (PLDA) and fabric-loop attach (FLA).
What is Fibre Channel?
Fibre Channel technology is outlined in the Information Systems - Fibre Channel
Protocol for SCSI (small computer system interface - FCP)
 standard, revision 12,
30 May 1995. Fibre Channel is a high-speed data transport technology used for
mass storage and networking. The IBM FAStT Host Adapter connects:
   Mainframe computers
   Super computers
   Workstations
   Storage devices
   Servers
Using a Fibre Channel arbitrated loop (FC-AL), 126 devices can be supported,
compared to 15 devices with Ultra SCSI.
Fibre Channel supports data transfer rates of 100 MB per second, which is more
than twice that of Ultra SCSI (40 MB per second). A multimode optical interface is
used for distances up to 500 meters. With increased connectivity and performance,
Fibre Channel is the technology preferred and used by system designers.
