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
hierarchical set of protocol layers. Defined within
these layers are rules for signal interfaces, serial
encoding and decoding, error control, frame
format and communications protocols.

models can be used in
a SAN (Storage Area Network) to connect a
variety of Fibre Channel and SCSI devices to
meet your needs.
ASANis asharedstoragearchitectureconnecting
computers and storage devices for online data
access.Eachconnectedsystemcandirectlyaccess
any attached storage device. Storage devices
could include RAID, tape backup, tape library,
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).
ATTO FibreBridge models provide the interface
between SCSI and Fibre Channel resources in
SANs. Possible configurations depend upon your
current hardware and what you need to do.

ATTO Technology FibreBridge 2300E/R/D Installation and Operation Manual
5 Connecting SCSI devices to SCSI ports
ATTO FibreBridge SCSI ports are used to connect SCSI storage devices into the Fibre Channel Storage
Area Network (SAN).
Each SCSI port is totally independent from the
any other SCSI port. This means that each bus is
capable of supporting 15 devices and each bus is
capable of 80 or 160 MB/sec. (Ultra, Ultra2 or
Ultra160).
However, you may use externally provided
software striping to create a RAID 0 group that
includes devices from both SCSI busses to
increase overall performance.
Another advantage of independent SCSI ports is
that each SCSI bus auto-negotiates the
appropriatesyncrateswiththeconnecteddevices.
If slower devices are mixed with faster Ultra160
devices, the bus will communicate at the rate of
the slowest device, thus wasting the performance
capabilities of the faster devices. You should
connect slower devices to one SCSI port and
connect faster devices on the other port on your
FibreBridge.
The FibreBridge supports a wide variety of SCSI
storage devices including stand-alone drives,
removable drives, JBODs, RAIDs, tape, CD and
DVD drives, changers, and libraries, magneto
optical drives.
To connect SCSI devices to the ATTO
FibreBridge:
1C
onnect a VHDCI connector from the SCSI
device to a port on the FibreBridge 2300.
2 Check the type of cable, cable length limit
and number of devices recommended for
each port. It is important to keep cable
lengths as short as possible to ensure the
highest signal quality and
performance.These cable lengths include
the wiring inside the devices.
3 SettheIDsof theSCSIdevices connected to
the bridge to a value other than 7. It is
recommended to use a sequential ID
starting at 0 for each device. Each SCSI port
in the ATTO FibreBridge has an internal
factory setting ID of 7, typical for a SCSI
initiator device.
NOTE
The entire SCSI bus will operate at the speed of the
slowest device. If you wish to mix devices of different SCSI
speeds on the bridge, it is best to place them on separate
busses. That is, put the slower devices on bridge SCSI bus 0,
and the faster devices on bridge SCSI bus 1. Each bus is
independent so each can operate at different speeds.
4 Terminate each SCSI bus after the last
device. The bridge is terminated internally.
Device type Cable limit
Ultra SCSI Single Ended (SE) 1.5 meters
Ultra SCSI High Voltage Differential (HVD) 25 meters
Ultra2 SCSI Low Voltage Differential (LVD) 12 meters

10
6 Connecting the Fibre Channel port
The Fibre Channel port on the ATTO FibreBridge 2300 connects the bridge into either a Fabric or
Arbitrated Loop.
Fibre Channel technology offers a variety of
cabling options including standard copper,
equalized copper, multimode fiber optic, and
single mode fiber optic.
The FibreBridge 2300 uses a Small Formfactor
Puggable (SFP) Fibre Channel interface. The type
of cable to use varies depending upon the
application, environment and distance. The
following tables illustrate the different cable
options available.
Make sure all cables are anchored securely at both
ends with the proper connectors.
Initial configuration
The FibreBridge can be configured to support
connectivity to arbitrated loop or fabric
topologies. (See Chapter 9 of this manual.)
When connecting these bridges to an F-Port
device, set the Port Connection Mode to “Point-
to-Point.”
➔ When connecting to a FL-port device, set
the Port Connector Mode to “Loop” mode.
➔ The FibreBridge uses public loop login to
log into a FL-Port on a fabric switch.
➔ The FibreBridge Port Connection Mode
can be set using the RS-232, Ethernet, or
in-band communication links.
Cable length Cable type Cable size Connector
Up to 175 meters multi mode fiber optic 62.5 micron LC
Up to 500 meters multimode fiber optic 50 micron LC
Up to 13 meters unequalized copper HSSDC-2

ATTO Technology FibreBridge 2300E/R/D Installation and Operation Manual
7 Accessing ATTO FibreBridge Services
Communicate with the ATTO FibreBridge through an in-band Fibre Channel link using ATTO
BridgeTools (a graphical interface configuration program), in-band SCSI commands, the RS-232 port
or serial headers, or the Ethernet port using ATTO BridgeTools, Command Line Interface or a menu.
ATTO FibreBridge Services can be used to
configure and tune the bridge for many different
environments and applications, update the
firmware, configure the addresses of the
connected SCSI devices, monitor internal power
and temperature status, report on hardware
diagnostics and log failures.
Three avenues are available:
➔ In-band SCSI over Fibre Channel
➔ RS-232 port or serial header
➔ Telnet over Ethernet
The next chapters of this manual provide details
on using the Command Line Interface and menu
system to access FibreBridge Services. Refer to
the ATTO BridgeTools manual for complete
instructions on how to use the program.
CAUTION
Any changes must be saved and will not take
effect until the ATTO FibreBridge is restarted.
Access the ATTO FibreBridge through in-band SCSI over Fibre Channel
One way to access the ATTO FibreBridge through
in-band SCSI over Fibre Channel is to use ATTO
BridgeTools, a Java-based graphical interface
configuration utility, to flash firmware and
manage configuration for many FibreBridge
models.
The ATTO BridgeTools program currently
supports Sun Solaris 8, MAC OS 10.1, Linux and
Windows 95/98/ME, NT and 2000.
Refer to the ATTO BridgeTools manual for
complete instructionstohowtoinstallandoperate
the program.
In-band SCSI commands (Write Buffer and Read
Buffer) may be issued to the FibreBridge to
manage configuration via two mechanisms:
➔ In-band CLI over SCSI, where ASCII CLI
(services) commands, may be issued via
Write Buffer. All CLI commands except
Menu are supported. Refer to Chapter 8.2.
➔ Buffer ID/value, where the application
program uses a SCSI CDB (command
descriptor block) to select the buffer ID of
the configuration paramaters to be
affected, and the new value of the
parameter.MostFibreBridgeconfiguration
options are available.
Access the ATTO FibreBridge over the RS-232 port
The ATTO FibreBridge supports remote
service operations over the RS-232 serial port
or serial header using standard terminal
emulation software available with most
systems.
1 Connect a DB-9 crossover serial cable (null
modem) between the ATTO FibreBridge
serial port or serial header and one of the
computer's serial COM ports. A gender
changer or DB-9 to DB-25 converter may be
needed depending on the cables being
used.
2 Enable the computer’s serial port and
initiate a terminal emulation link.
3 Set the following serial parameters in your
terminal program: Bits per second: 9600,
Data Bits: 8, Parity: None, Stop Bits: 1, Flow
Control: None. Use ASCII as the terminal
type. Echo should be on.
4 You may use a graphical interface
(BridgeTools), command line interface (CLI)
or menu system as explained in the rest of
this manual.

12
Access methods
Configure the ATTO FibreBridge for a network over the Ethernet port
The 10/100 BaseT Ethernet port provides Telnet-
based monitoring and management. The default
IP address is 10.0.0.1; the default subnet mask is
255.255.255.0. You don’t need to do anything
more if you want to use the default, but these
parameters can be changed using the RS-232 port
or Telnet. The ATTO FibreBridge should first be
configured for the network using the RS-232 port
to establish the correct IP address.

Access the ATTO FibreBridge using Telnet or FTP over Ethernet
To access the ATTO FibreBridge via Ethernet:
1 Connect an Ethernet cable between the
FibreBridge and a 10/100Base-T
connection. You may need a crossover
cableconnectingdirectlytoacomputer. The
ATTO FibreBridge will auto detect the
Ethernet speed if configured to do so.
2 Access using any standard Telnet program.
To connect via Telnet:
1 Supplythe IP addressto theTelnetprogram.
The local echo should be set to on if the
Telnet software supports it. Use Vt100 for
communication.
2 Verify that the bridge can be accessed on
the local Ethernet by using the Ping utility.
On most systems, type ping <IP Address>. If
the product module does not repsond, it
may not be connected correctly to the
network, or is somehow unreachable by the
computer from which it is being pinged.
Check network connections and security as
well as the ATTO FibreBridge.
To set up and configure FTP:
1 Ensure that the FTP program is in binary
mode. Access the ATTO FibreBridge at the
IP address that was previously set (or the
default).
2 Log into the ATTO FibreBridge. The
username thebridgewill acceptis sysadmin.
Enter userid as the password.
3 You may use a graphical interface
(BridgeTools) as explained in the rest of this
manual.

ATTO Technology FibreBridge 2300E/R/D Installation and Operation Manual
8 Using ATTO FibreBridge Services
Configuration of the ATTO FibreBridge, also known as FibreBridge Services,
,
is available via ATTO
BridgeTools (a graphical user interface configuration manager), Command Line Interface (CLI) or a
menu.
FibreBridge Services includes displaying and
modifying various attributes of FibreBridge
operation, as well as the update of firmware. You
may use a graphical interface (BridgeTools),
command line interface (CLI) or menu system,
depending on your FibreBridge model, what you
want to accomplish, and the method you are using
to access FibreBridge services.
ATTO BridgeTools
The simplest way to communicate with the bridge
is to use BridgeTools, a Java-based graphical
interface configuration utility designed to flash
firmware and manage the configuration for all
models of the FibreBridge.
The ATTO BridgeTools program currently
supports Sun Solaris 8, MAC OS 10.1, Linux and
Windows 95/98/ME, NT and 2000.
BridgeTools detects which FibreBridge model is
available and presents you with the applicable
configuration options. At the startup, a screen will
present choices to communicate with the
FibreBridge. You can choose between an in-band
connection direct over the Fibre Channel link, an
RS-232 port or an Ethernet port.
A tabbed panel interface presents configuration
parameters in a simple, one-window display.
Message boxes, icons, drop-down boxes, menu
bars and other common graphical constructs lead
you through the configuration process.
Refer to the ATTO BridgeTools Manual for
complete instructionstohowtoinstallandoperate
the program.
Command Line Interface (CLI)
The Command Line Interface provides access to
FibreBridge Services through ASCII command
lines. CLI is designed to be used by applications
such as BridgeTools and “power users.” The
initial display, after powering up the unit or
restarting the firmware, will contain the
information in Exhibit 8-1. Once the initial
display is complete, with the word Ready, you are
in the Command Line Interface mode.
Type Help to display a list of all commands
available.
Menu mode
The Menu contains most commands available
through CLI but in a hierarchal format. It follows
a standard menu/choice model.
The initial display, after powering up the unit or
restarting the firmware, will contain the
information in Exhibit 8-1. Once the initial
display is complete, with the word Ready, you are
in the Command Line Interface mode.
Type Menu and you will enter the menu system.

ATTO Technology FibreBridge 2300E/R/D Installation and Operation Manual
8.1 Command line use and guidance
The command line interface (CLI) provides access to the ATTO FibreBridge Services through a set of
ASCII commands. CLI commands may be entered while in CLI mode.
FibreBridge Services provide configuration and
monitoring for the FibreBridge. Other programs
and “power users” use the command line interface
(CLI), a set of ASCII-based commands, to
perform these tasks. CLI commands may be
entered while in CLI mode.
➔ CLI commands are context sensitive and
generally follow a standard format:
[Get | Set] Command [Parameter 1 | Parameter 2]
followed by the return or enter key
➔ CLI commands are case insensitive: you
may type all upper or all lower case or a
mixture. Upper and lower case in this
manual and the help screen are for
clarification only.
➔ Commands generally have three types of
operation: get, set and immediate. Theyare
summarized here and in Exhibit 8.1-1.
➔ The get form returns the value of a
parameter or setting and is an
informational command.
Responses to get commands are specified
in the Results field for each command,
followed by Ready.
➔ The set form is an action that changes the
value of a parameter or configuration
setting. It may require a
SaveConfiguration command and a
restart of the system before it is
implemented. The restart can be
accomplished as part of the
SaveConfiguration command or by using
a separate FirmwareRestart command. A
number of set commands may be issued
before the SaveConfiguration command.
Responses to set commands are either an
error message or Ready. *. The asterisk
indicates you must use a
SaveConfiguration command to finalize
the set command. SaveConfiguration will
ask whether you want to restart the system
or not.
➔ Set commands which do not require a
SaveConfiguration command, defined as
immediate commands, are immediately
executed.
Responses to Immediate commands are
either an error message or data results
followed by Ready.
➔ Symbols, typefaces and abbreviations used
to indicate functions and elements of the
command line interface used in this
manual include those found below.
Exhibit 8.1-1 Command explanations.
Set commands configure the FibreBridge and display what you have changed after completing
the task. Commands which require a
SaveConfiguration
command to complete their
implementationwillreturnReady.*.Set commandswhich do notrequire a
SaveConfiguration
command are immediately executed.
Get commands display information about the configuration of the FibreBridge. Responses to
get commands are specified in the Results field for each command, followed by Ready.
Screen messages, also called returns, may be either terse, with just the current information, or
verbose, with labels and the current information.
