Chapter 1. Introduction
The IBM SAN Fibre Channel Switch 2109 Model S16 is a 16-port, fibre-channel,
switch. The IBM 2109 Model S16 Switch consists of a system board with
connectors for supporting up to 16 ports, and a fabric operating system for creating
and managing a fabric. A
fabric
is an active, intelligent, nonshared interconnection
scheme for a fibre channel.
Figure 1 shows the front view of the 2109 Model S16 Switch. Ports are numbered
sequentially starting with zero for the left-most port. The switch faceplate includes a
silk screen imprint of the port numbers. Up to two power supplies are supported;
these are shown to the left and right of the switch ports in Figure 1.
Switch features
The switch is a high-performance, fibre-channel, switch with the following features:
Simple
Easy setup and configuration. After the power-on self-test (POST), you
need only to add the internet protocol (IP) address to the switch. The
remainder of the switch setup is automated.
Intelligent
The fabric operating system of the switch allows discovery of all connected
devices and determines optimum data paths without intervention. It
supports up to 32 interconnected switches.
Flexible
Modular design with multiple GBIC (Gigabit interface converter) modules
that support fiber transmission media. The modular construction of the
switch gives the switch a range of flexibility in creating, upgrading,
maintaining, and configuring a fabric.
Reliable
Highly integrated, reliable, multifunction ASIC (application specific integrated
circuit) devices are used throughout the switch.
