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.
All ATTO

models can be used in
a SAN (Storage Area Network) to connect a
variety of Fibre Channel and SCSI devices to
meet your needs.
ASANisashared storagearchitectureconnecting
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.

4 How to connect SCSI devices to SCSI ports
ATTO FibreBridge
TM
SCSI ports are used to connect SCSI storage devices into the Fibre Channel
Storage Area Network (SAN).
A FibreBridge may have the following types of
SCSI ports:
➔
Ultra 2 (LVD) SCSI– 80 MB/sec. max per
bus
➔
Single Ended Ultra SCSI – 40 MB/sec.
max per bus
A FibreBridge with an LVD SCSI personality
module is downward compatible with Single
Ended Ultra SCSI as well as Fast, Wide, or
Narrow SCSI devices.
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 40 or 80 MB/sec. (Ultra or Ultra2).
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
appropriatesyncrates withtheconnected devices.
If slower devices are mixed with faster Ultra2
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, libraries and magneto
optical drives.
To connect SCSI devices to the ATTO
FibreBridge:
1C
onnect a VHDCI SCSI connector from the
SCSI device to a port on the FibreBridge
1190.
Check the type of cable, cable length limit and
number of devices recommended for each port. It is
importantto keepcablelengthsasshortaspossible
to ensure the highest signal quality and
performance.Thesecablelengthsincludethewiring
inside the devices.
2 Setthe IDsof the SCSIdevices connectedto
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.
3 Terminate each SCSI bus after the last
device. The bridge is terminated internally.

5 How to connect the Fibre Channel port
The Fibre Channel port(s) on the ATTO FibreBridge
TM
connect 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 1190E uses
an MIA compliant DB-9 or
Short Wave fiber optic SE connector.
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 atboth
ends with the proper connectors.
Initial configuration
The FibreBridge can be configured to support
connectivity to arbitrated loop or fabric
topologies. (See Chapter 6 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.

6 ATTO FibreBridge addressing
The ATTO FibreBridge
TM
allows parallel SCSI devices to participate in a Fibre Channel arbitrated loop
or on a fabric. Fibre Channel and parallel SCSI use different models to address devices. The FibreBridge
translates between these addressing models.
The chart below is a simplified overview of data
and control flow between the application and the
SCSI device through a number of stages.
Fibre Channel World Wide Name (WWN)
Each Fibre Channel device is assigned a unique
World Wide Name (WWN). The WWNis used to
identify all Fibre Channel devices. The 64-bit
WWN has the following format:
The Institute of Electrical and Electronics
Engineers (IEEE) assigns each manufacturer a
unique Company ID. The Device ID field
contains a unique value assigned by ATTO
Technology to every Fibre Channel product
produced by ATTO Technology.
Arbitrated Loop Port Address (AL_PA)
On a Fibre Channel Arbitrated Loop, the
FibreBridge appears at a single Arbitrated Loop
Port Address (AL_PA). Each device on an
arbitrated loop is assigned a unique AL_PA
during loop initialization. The FibreBridge
supports both modes of AL_PA assignment,
commonlyreferredtoashardand softaddressing.
Soft addressing allows the loop initialization
master to assign the FibreBridge a unique AL_PA
during the loop initialization process. The AL_PA
assigned cannot be determined before loop
initialization. For example, adding newdevices to
an arbitrated loop may change the AL_PA
assigned to the FibreBridge.
Hard addressing allows a predetermined AL_PA
to be assigned to the FibreBridge. The
FibreBridge will try to acquire the desired hard
AL_PA. If another device has already been
assigned the specified AL_PA, the FibreBridge
will acquire a currently unassigned AL_PA.
ATTO BridgeTools software allows you to select
either hard or soft addressing modes. The default
mode is soft addressing.
Addressing Devices Connected to the
FibreBridge
SCSI devices connected to the FibreBridge also
show up as Fibre Channel LUNs to the host
computer. SCSI devices must be on the same

FibreBridge. The FibreBridge SCSI ports must be
set to different SCSI IDs than the devices on the
bus.
SCSI devices are mapped manually to desired
Fibre Channel port and Fibre Channel LUNs.
Manual mapping allows you to maximize the
efficiency and performance of your SCSI devices
while allowing great flexibility.
Manual SCSI Device Mapping
TheFibreBridgecan be commanded to findall the
SCSI devices on its SCSI bus. With this
information you then decide where you want to
place these devices on the Fibre Channel ports.
In the chart at right, the SCSI device on SCSI bus
0 at SCSI address of ID 0 LUN 0 is being mapped
to Fibre Port 0 (on the FibreBridge) at Fibre
Channel LUN 4.
Note: two SCSI devices cannot be mapped to
the same Fibre Port and Fibre Channel LUN.
Also, if the sameSCSIdevice ismapped to two
different Fibre Port and/or Fibre Channel
LUN, these Fibre Port and Fibre Channel
LUNs will be taken offline automatically until
the conflict is resolved.

7 How to access ATTO FibreBridge Services
Communicate with the ATTO FibreBridge
TM
through an in-band Fibre Channel link using in-band SCSI
commands, the RS-232 port or the Ethernet (Telnet/FTP) port using Command Line Interface.
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
➔
Telnet or FTP over Ethernet
The next chapters of this manual provide details
on using the Command Line Interface to access
FibreBridge Services.
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
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 are
supported. Refer to Chapter 7.2.
➔
Buffer ID/value, where the application
program uses a SCSI CDB (command
descriptor block) to select the buffer ID of
the configuration parameters 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
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 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 the command line interface
(CLI) as explained in the following chapters.
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.
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
cableconnectingdirectlytoa computer.The
ATTO FibreBridge will auto detect the
Ethernet speed.
2 Access using any standard Telnet program.

12
Access methods
To connect via Telnet:
1 Supplythe IPaddresstotheTelnetprogram.
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 respond, 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 the bridgewillacceptis sysadmin.
Enter userid as the password.
3 Use the command line interface (CLI) as
explained in the following chapters.

ATTO Technology FibreBridge 1190E Installation and Operation Manual
7.1.1 General use commands
The CLI commands outlined in this chapter get information or perform functions which are used in a
variety of situations with the FibreBridge.
CLI commands are case insensitive (upper and
lower case allowed anywhere). Commands generally follow a standard format:
[Get | Set] Command [Parameter 1 | Parameter 2]
followed by the return or enter key.
FibreBridgeName
Specifies the eight-character name assigned to the FibreBridge used to identify individual FibreBridge units. It is not the World Wide Name (WWN).
Actions:
set FibreBridge Name [value]
Information:
get FibreBridgeName
SaveConfiguration
Info
Displays version numbers and other production information for key components within the FibreBridge
Action:
none
Information:
Info
Help
Displays a list of available commands. If command name is specified, displays detailed command-specific information.
Action:
none
Information:
Help [command name]
Reserve
Reservation of the FibreBridge is implicit: once the configuration image is changed by any user of services, the FibreBridge becomes RESERVED.
Executing a SaveConfiguration, RestoreConfiguration or FcRestart RELEASES the FibreBridge so that other services users may access it.
Limits: When FibreBridge services interface is RESERVED, set commands from other users are unavailable.
At least one interface must always have access to the FibreBridge.
Action:
Reserve
Information:
none
Return: [enabled | disabled]
RestoreConfiguration
Restores configuration to either the default configuration or the configuration last saved into non-volatile memory. The saved option will undo any
changes made since the last save.
Actions:
RestoreConfiguration [Default | Saved]
Information:
none
SaveConfiguration
Many commands require a SaveConfiguration command to be executed. This will be indicated by the return
Ready. *.
When you invoke
SaveConfiguration, the current configuration is permanently saved in the FibreBridge and the new configuration becomes the active configuration.
If a firmware restart is required to make the requested change permanent, you will see a prompt asking you to confirm the restart. You can override
this request by indicating the override value on the command line. You may make several changes through commands and SaveConfiguration before
implementing the restart, but once you have restarted the FibreBridge, all the command changes created before the restart and save will be
implemented. If you select the restart option, the FibreBridge will execute its complete start up cycle.
Limits: Restart or no Restart parameter is optional
Actions:
SaveConfiguration <Restart| NoRestart>
Information:
none
Returns: [Configuration saved |
Restart is necessary...
Do you wish to restart (y/n)? y
Restarting...]
VerboseMode
Specifies the detail of feedback for the command line interface. Disabling this option removes parameter names from action commands and removes
descriptions from information commands.
Limits: enabled or disabled Default: enabled (returns have parameter information)
Actions:
set VerboseMode [enabled | disabled]
Information:
get VerboseMode
