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

4 How to connect SCSI devices to SCSI ports
ATTO FibreBridgeTM 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 appropriate sync rates with the connected 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 FibreBridg e su pp or ts a wide var iet y of SC SI 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:
onnect a VHDCI SCSI connector from the
1C
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 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.
Device type Number of
devices
Ultra SCSI Single Ended (SE)
Ultra SCSI Single Ended (SE)
UltraSCSI High Voltage Differential (HVD)
Ultra2 SCSI Low Voltage Differential (LVD)
2 Set the IDs of the SCSI devices 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 slow est device. If you wish to mi x devices o f di fferent SCSI speeds on the bridge, it i s best to place them on separate busses. That is, put the slower devices on bridge SCSI bus 0, and th e faster d evices on bridge SCSI bus 1. Each bus is independent so each can operate at different speeds.

5 How to connect the Fibre Channel port
The Fibre Channel port(s) on the ATTO FibreBridgeTM 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 op ti c.

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 6 of this manual.)
When connecting these bridges to an F-Port device, set the Port Connection Mode to “Point­to-Point.”
When connecting to a FL-port device, set
the Port Connector Mode to “Loop” mode. The FibreBridg e use s pu bl ic lo o p logi n 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 com m u n ic at io n li nk s.

The ATTO F ibreBridgeTM allows par allel SC SI dev ices to parti cipate in a F ibr e Chan nel arbitr ated loop or on a fabric. Fibre Channel and parallel SCSI use different models to address devices. The FibreBridge translates between these addressing models.

Fibre Channel World Wide Name (WWN)
Each Fibre Channel device is assigned a unique W orld W ide Name (WWN). The WWN is 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 Chann e l Arbi t ra ted Lo op , th e FibreBridge appears at a single Arbitrated Loop Port Address (AL_P A ). Each device on an arbitrated loop is assigned a unique AL_PA during loop initialization. The FibreBridge supports both modes of AL_PA assignment, commonly referred to as
hard
and
soft addr essing
Soft addressing allows the loop initialization master to assign the FibreBridge a unique AL_P A during the loop initialization process. The AL_PA assigned cannot be determined before loop initialization. For example, adding new devices 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 softwa re 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 addressing level as the SCSI portion of the

FibreBridge. The FibreBridge SCSI ports must be set to different SCSI IDs than the devices on the bus.
Y o u may map SCSI de vices manual ly by using the Command Line Interface RouteXXX family of commands. See Chapter 7.1.2 for more details.
ATTO FibreBridge addressing
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
The FibreBridge can be commanded to find all the SCSI devices on its SCSI bus. With this informat io n yo u th e n de c id e whe r e yo u 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 I D 0 LUN 0 is being mapped to Fibre Port 0 (on the Fibr eBr id g e) at Fibre Channel LUN 4.
Note: two SCSI devices cannot be mapped to
the same Fibre Port and Fibre Channel LUN.
Also, if the same SCSI device is mapped to two
different Fibre Port and/or Fibre Channel
LUN, these Fibre Port and Fibr e Channel
LUNs will be taken offline automatically until
the conflict is resolved.
