1 Fibre Channel is a key technology for storage
Fibre Channel is a serial communications technology designed to transfer large amounts of data
between a variety of hardware systems over long distances. It is a key technology for applications that
require shared, high bandwidth access to storage.
Fibre Channel provides a logical point-to point
serial channel for the transfer of data between a
buffer at a source device and a buffer at a
destination device. It moves buffer contents from
one port to another, without regard to the format
or meaning of the data, so different upper level
protocols are able to run over Fibre Channel
hardware.
The Fibre Channel architecture is structured as a
hierarchica l set of pro tocol laye rs. Def ined with in
these layers are rules for signal interfaces, serial
encoding and decoding, error control, frame
format and communications protocols.
A SAN is a shared storage architecture connecting
computers and storage devices for online data
access. Each connected system can directly access
any attached storage device. Storage devices
could include RA ID , ta pe ba c k up , tape libr a ry,
CD-ROM library or JBOD.
SANs maintain greater fault tolerance and load
balancing by supporting server clustering and
failover (the ability for one server to take over for
another in the event of a failure).
The ATTO FibreCenter™ 3400 hub integrates
industry-leading performance and Storage Area
Network capabilities into mid-range applications.

Some terms used in the Fibre Channel industry are defined below . More information is available through
the F ibre C hannel Industry Assoc iation (www.fibrechannel.com), the Storage Area Networking Industry
Association (www.snia.org) and the Fibre Channel Consortium (www.iol.unh.edu).

FC-AL Fibre Channel Arbitrated Loop: A Fibre Channel network in which up to 126
nodes are connected in a loop topology, with each transmitter connecting to the
receiver of the device to its logical right. The Fibre Channel Arbitrated Loop

2 ATTO FibreCenter supports diverse SAN needs
The ATT O F ibr eCenter 3400 pr o vides a 2-gigab it Fibre Chan nel r ac kmo unt hu b conf igured with eight
Fibre Channel ports and an Ethernet management port.
The ATTO FibreCenter 3400 integrates industryleading performance and Storage Area Network
capabilities into mid-range applications.
Quick start i nstructions
The ATTO FibreCenter 3400R/D offers a
variety of ways to connect into a SAN. The
following is a quick start description:
1 Slide the hub module horizontally into the
rack enclosure until you feel it make contact
with the backplane connector.
2 Secure the hub module by tightening the
two thumbscrew s (hand tight).
3 Apply power to the rack enclosure. The
FibreCenter is now active.
4 Connect to the management port via a
standard RJ45 Ethernet cable.
5 Connect Fibre Channel devices to the ATTO
FibreCenter using SFPs and standard
cables manufactured for Fibre Channel use.
6 Connect a host computer to the FibreCenter
3400. The default IP address of the hub is
192.168.1.1. Unless your network is running
A vailable as a Fibre Channel rack system module,
it provides dependable performance for high
availability systems through hot swappable, dual
power modular design.
under 192.168.1.X, you will need to use a
crossover Ethernet cable to connect.
7 Change the IP address of the host computer
to 192.168.1.X (where X does not equal 1).
8 Launch Hyperterminal.
9 From the menu bar at the top, select
New Connection
10 Enter a name for the connection.
11 Select
TCP/IP (Winsock)
as the connection
method.
12 Enter the IP address of the FibreCenter
(default is 192.168.1.1)
13 Enter
zonedhub
when prompted for the login
and your passw ord when y ou are prompted.
14 Y ou should no w be connected. Type
a list of commands. Enter the CLI
commands required to set up your s ystem if
different from previousl y set configurations.
