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 80 MB/sec. max per bus Single Ended Ultra SCSI 40 MB/sec. max per bus High Voltage Differential (HVD) Ultra SCSI 40 MB/sec. max per bus The high voltage differential (HVD) FibreBridge is compatible only with HVD SCSI devices.
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 type of cable to use varies depending upon the application, environment and distance. The following tables illustrate the different cable options available.
3 Configuring the FibreBridge 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.

Firmware version 002R release date Feb 14 2001, 16:01:43 Build 002R Power-On Self-Test Completion Status: GOOD 64 Megabytes of RAM Installed. 3 1.0624 Gb/s Fibre Channel Interfaces. 4 LVD SCSI Interface Ports.
3.1 ATTO FibreBridge addressing The ATTO FibreBridge 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 Institute of Electrical and Electronics The chart below is a simplified overview of data Engineers (IEEE) assigns each manufacturer a and control flow between the application and the unique Company ID.
3.1.1 Mapping devices Access to SCSI devices is via Fibre Port and Fibre LUN addresses mapped to SCSI bus, target and LUN. CLI commands are used to modify the mapping. The Command Line Interface commands AutoMap, AddressMap and RouteXxxxx map Fibre Channel ports and LUNs to SCSI bus/target/LUNs. Host applications use the Fibre port and Fibre LUN to access specific SCSI devices.
the FibreBridge and Services target LUN and the SCSI devices currently attached to the FibreBridge. Exhibit 3.1-1 Several commands and features are not available in AddressMap C Mode: AutoMap, BootScanPorts, FibreBridgeTargetLUN, ServicesLUN, Route, RouteDisplay, RouteChange, RouteOnline, RouteOffline, SpeedWrite, SpeedWriteDefault. Exhibit 3.
RouteXXX family You can then manually map the devices using the RouteXXX family of commands or the AutoMap command (see Chapter 4.1.8) available through the Command Line Interface or the menu or by using ATTO BridgeTools (see Chapter 4 and Chapter 3.1). RouteDisplay displays the current mapping, if AddressMap C has not been enabled, in Fibre port, Fibre LUN order, showing the mapped SCSI bus/target/LUN, and the current status of the device (online, offline, disabled, mapped, unmapped).
3.2 Handling multiple initiators Several Fibre Channel hosts or initiators may initiate commands through the FibreBridge to SCSI devices. The basic mechanism to resolve possible conflicts among initiators is to use SCSI Reserve and Release commands. A Fibre Channel host may need exclusive access to a SCSI device. SCSI Reserve and Release commands allow logical units to be reserved or released under host control.
Multiple Fibre Channel initiators 1 2 3 4 5 6 7 8 9 Fibre Channel Initiator 1 sends the Reserve command through the SAN to the FibreBridge. The FibreBridge determines that no reservation conflict exists at Tier 1. The FibreBridge records the initiator ID (WWN) in its internal database. The FibreBridge sends the Reserve command to the SCSI target. The initiator is notified of reservation success: the SCSI target is reserved.
4 Accessing ATTO FibreBridge Services Communicate with the ATTO FibreBridge through the RS-232 serial port, the Fibre Channel port or the Ethernet port using ATTO BridgeTools, Command Line Interface or a menu. ATTO FibreBridge Services 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.

4.2 FibreBridge menu text-based CLI interface Configuration of many models of the ATTO FibreBridge is available via a menu which contains most commands available through CLI but in a hierarchical user-friendly format. It follows a standard menu/choice model. Configuration of the FibreBridge includes Typing “a” will enable loop mode, typing “b” will displaying and modifying various attributes of enable point-to-point mode. FibreBridge operation, as well as the update of Examples firmware.
4.3 ATTO BridgeTools provides graphical interface The simplest way to communicate with the ATTO FibreBridge is to use ATTO BridgeTools, a Java-based graphical interface configuration utility designed to flash firmware and manage the configuration for all models of the FibreBridge. Configuration of the FibreBridge includes displaying and modifying various attributes of FibreBridge operation, as well as the update of firmware.
4.4 In-band CLI uses SCSI over Fibre port In-band Command Line Interface (CLI) configures and manages the ATTO FibreBridge using SCSIbased CLI commands over a Fibre port connection. In-band CLI allows a programmer to configure the FibreBridge while it is moving data. Using a programmer’s interface, ATTO FibreBridge Services CLI commands as described previously in this manual may be implemented. The only command not available is menu.
➔ ASCII data ➔ 8 KBytes (8192 bytes) in length ➔ terminated with a NULL character (0x00) Exhibit 4.4-1 ➔ Characters following the NULL character are meaningless. A CHECK_CONDITION, INVALID_PARAMETER _IN_CDB will be returned to an initiator that specifies an incorrect Buffer ID, Mode, Length or Buffer Offset. The Mode is always Data (0x2), the Buffer ID is always 0 and the Buffer Offset is always 0. The SCSI command process: reserve the FibreBridge, send the command, release the FibreBridge.
5 Enhancing performance SpeedWrite is a method to improve the performance of WRITE commands to SCSI devices attached to the FibreBridge 4500 enabled by CLI commands. SpeedWrite is a method to improve the performance of FCP WRITE commands to SCSI devices attached to the FibreBridge. Using the CLI command SpeedWrite, you can specify the SCSI bus, target and LUN of a mapped device or specify [all] to set or get the state of all currently mapped SCSI devices.
6 Updating firmware The ATTO FibreBridge has several processors which control the flow of data. The firmware to control these processors can easily be upgraded in the field using the WriteBuffer command over the in-band Fibre Channel connection, PUT command from an FTP connection, or ZModem utility over an RS-232 serial connection. The FibreBridge firmware is distributed as a compressed .JAR file and can be obtained from the ATTO Technology, Inc. web site at www.attotech.com.
7 Serverless backup support Serverless Backup is an application that allows data to be copied between two storage devices (Fibre Channel disks, SCSI disks and SCSI tapes) with minimal intervention from a server. As the volume of data on a network grows, the resources required to back up this data also grow. Data protection requires that large volumes of data be copied from on-line storage devices to dedicated archive devices.
