CHAPTER 1
GFS-2 PRODUCT OVERVIEW
This chapter provides information on the following topics:
• Product Overview
• Key Features
• Management Options
• Deployment Capabilities and Examples
Product Overview
The GFS-2 switch provides seamless bi-directional integration of Fibre
Channel (FC) and Gigabit Ethernet (GbE) networks over long distances
without disruption or technology changes. The GFS-2 provides entry to the
LAN/SAN environment using IP Translation. Its OpenIP™ architecture
provides bridging, tunneling, and resource allocation services across the FC
fabric to the GbE boundary and back again.
The GFS-2 provides one GbE and one FC port for implementing a Gateway
between a FC and a GbE environment.
Key Features
•Bi-directional and full-bandwidth
Full bandwidth connectivity between all ports. The GFS-2 provides seamless
connectivity of Fibre Channel over an IP network. The 2 Gb/s backplane on the
GFS-2 allows for full duplex operation on all ports simultaneously.
•Versatility
The GFS-2 is supplied with one FC port and one GbE port.
•Flexible control
Remote control, fabric management, and monitoring are provided using
SANman™.

GFS-2 Product Overview
Management Options
The GFS-2 provides two management applications:
•Command Line Interface (CLI)
CLI commands are entered using the application command prompt. The CLI is an
inherent part of the switch’s embedded software and may be activated using either a
terminal emulator, through the serial port, or a Telnet application, through an IP
network. The CLI enables a user to configure and manage the currently connected
switch.
• SANman
SANman is installed on the control console. It provides a real-time graphical view
of each of the Fabrics in the network and the relationship of the elements within the
Fabrics. SANman provides extensive configuration, management, monitoring and
analysis functions at the network level.
The GFS-2 utilizes three methods of management:
• Console Management (Serial)
• Out-of-Band Management (Telnet, SANman)
• In-Band Management (Telnet, SANman)
Console Management Overview
To manage a switch using a console, connect the switch to a PC and use a
terminal emulation application, such as HyperTerminal, to control and manage
the switch.
In-Band Management Overview
Any communication within the switching Fabric that utilizes the GFS-2 native
routing is considered to be In-Band to the switch. Examples of this would be
Fibre Channel frames entering the switch through a FC port, tunneled data
coming through an IP Tunneling (BBW) port, or Gigabit Ethernet traffic
coming through an IP Translation (BBL) port.
NOTE. FC data tunneled through an IP Tunneling port is treated as if it entered
the switch through a standard E_Port connection.

LightSand GFS-2 Hardware Guide 1-3
In-Band Management Overview
Figures 1-1 and 1-2 illustrate examples of In-Band management through a FC
port and using an IP Translation Ethernet connection.
Figure 1-1 IN-BAND MANAGEMENT EXAMPLE THROUGH AFC PORT
Figure 1-1 illustrates a Management Workstation running Telnet or SANman.
The Workstation is connected to the GFS-8 switched fabric. This is In-Band
management because the data originates ON the native switched fabric. The
workstation may manage any switch on the fabric, including switches that are
on the opposite side of the BBW link (IP cloud) providing that they are on the
same subnet. The GFS-8 is a switch, not a router, and has one In-Band IP
address assigned to it.
