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 FibreBridge
models can be used in a
SAN (Storage Area Network) to connect a variety
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 RAID, tape backup, tape library, CD-ROM library, standalone disk drives 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. of Fibre Channel and SCSI devices to meet your needs.

The ATTO FibreBridge 4500R weighs about 10 pounds. Be careful when installing it a rack.
Always stack the rack from the bottom up to ensure a stable and safe rack.
Minimum rack depth: 10 inches.
Make sure the power requirements of the ATTO FibreBridge 4500R plus the cumulative power draw of the other equipment in the rack do not overload the supply circuit and/or wiring of the rack.
Properly ground the FibreBridge 4500R to the rack equipment. The earth ground connection must be maintained when supply connection is other than direct connection to the branch circuit.
Install the FibreBridge horizontally within the rack so it does not reduce the air flow within the rack. The maximum ambient temperature for the ATTO FibreBridge 4500R should not exceed 50° C

2.3 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).
A FibreBridge may have the following types of SCSI ports:
Ultra 2 (LVD) SCSI
Single Ended Ultra SCSI
High Voltage Differential (HVD) Ultra SCSI
80 MB/sec. max per bus
40 MB/sec. max per bus
40
MB/sec. max per bus
The high voltage differential (HVD) FibreBridge is compatible only with HVD SCSI devices. An LVD FibreBridge 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 all 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 another port on your FibreBridge.
To connect SCSI devices to the ATTO FibreBridge:
1Connect a VHDCI SCSI connector from the
SCSI device to a port on the FibreBridge
4500.
Check the type of cable and cable length limit 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 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
2 Set the IDs of the SCSI devices connected to
the bridge to a value other than 7. You should 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 busses 0 and 1, and the faster devices on bridge SCSI busses 2 and 3. 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.
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.

2.4 Connecting the Fibre Channel ports
The Fibre Channel ports on the ATTO FibreBridge 4500C/R/D 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 4500C/R/D uses an SC fiber optic cable connector.
Cable length Cable type Cable size Connector
Up to 175 meters multi mode fiber optic 62.5 micron SC optic connector
Up to 500 meters multi mode fiber optic 50 micron SC optic 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 at both ends with the proper connectors.

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, commonly referred to as
hard
and
soft addressing
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 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 software allows you to select either hard or soft addressing modes. The default mode is soft addressing.
Addressing devices
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.
