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.

Not all components are hot swappable: please read installation and maintenance instructions carefully.
2 ATTO FibreBridge supports diverse SAN needs The ATTO FibreBridgeTM family of products provides a Fibre Channel-to-SCSI bridge available as a embedded board, a stand alone enclosure that can be fitted for rackmount integration, or a desktop unit, depending on the model and your needs. The ATTO FibreBridge family of products share common configuration options and functions to provide the most versatile connectivity options available. Each product has been engineered to address specific customer needs.
Exhibit 2-1 The following chart provides an overview of the features and capabilities for the newest FibreBridge models. Contact your authorized ATTO representative or visit ATTO Technology’s website, www.attotech.com, for additional information.
3 ATTO FibreBridge 1190E characteristics The ATTO FibreBridgeTM 1190E is a 1 x 2 (one Fibre Channel port with two SCSI ports) Fibre Channel to SCSI bridge for high throughput enterprise environments designed for mission-critical applications.
Ethernet port The 10/100 Base T Ethernet port supports SNMPand Telnet-based monitoring and management through a command line interface or menu system. Serial/Ethernet RJ45 port The RJ45 port may be used for either serial or Ethernet connections depending on the jumper settings and cable. The factory sets the jumpers in a serial configuration across the top and middle rows of the selector header. To enable an Ethernet configuration, move all the jumpers in the selector header to the middle and bottom rows.
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: To connect SCSI devices to the ATTO FibreBridge: ➔ Ultra 2 (LVD) SCSI– 80 MB/sec. max per bus ➔ Single Ended Ultra SCSI – 40 MB/sec.
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 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.
6 ATTO FibreBridge addressing The ATTO FibreBridgeTM 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 and control flow between the application and the Engineers (IEEE) assigns each manufacturer a SCSI device through a number of stages.
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 information you then decide where you want to place these devices on the Fibre Channel ports.
7 How to access ATTO FibreBridge Services Communicate with the ATTO FibreBridgeTM 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.
computer from which it is being pinged. Check network connections and security as well as the ATTO FibreBridge. To connect via Telnet: 1 To set up and configure FTP: 1 2 3 Ensure that the FTP program is in binary mode. Access the ATTO FibreBridge at the IP address that was previously set (or the default). Log into the ATTO FibreBridge. The username the bridge will accept is sysadmin. Enter userid as the password. Use the command line interface (CLI) as explained in the following chapters.
7.1 Command Line Interface use and guidance Configuration of the ATTO FibreBridgeTM, also known as FibreBridge Services,, is available via the Command Line Interface (CLI). FibreBridge Services includes displaying and modifying various attributes of FibreBridge operation, as well as the update of firmware using the 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 and “power users.
Exhibit 7.1-2 Command conventions.
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 Commands generally follow a standard format: lower case allowed anywhere). [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.
7.1.2 Mapping commands Access to SCSI devices is via Fibre Port and Fibre LUN addresses mapped to SCSI bus, target and LUNs. The factory default mapping is shown in Appendix A. CLI commands are used to modify the mapping. The RouteXxxxx and AutoMap commands provide the mechanism to map Fibre Channel Port/LUN to SCSI bus/target/LUN. Host applications use the Fibre Port and Fibre LUN to access specific SCSI devices.
FcHard Used to enable or disable Fibre Channel hard address assignment. Under soft addressing, the FibreBridge loop address is assigned during loop initialization. Use FcHardAddress (described below) if you enable hard addressing. Limits: applies to all Fibre Channel ports Actions: setFcHard [enabled | disabled] SaveConfiguration Default: enabled, or hard addressing Information: get FcHard FcHardAddress Sets/displays the value used as the FC-AL hard address.
RouteOffline Sets a route to offline or reports its status as offline or going offline Information: get RouteOffline [fp] Mapping commands Action: set RouteOffline [fp] [fl] Returns: [fp] [fl] [sb] [st] [sl] [Going offline|Offline] RouteOnline Sets a route to online or reports its status.
7.1.3 Diagnostic commands ATTO FibreBridgeTM diagnostic commands help validate FibreBridge operation and diagnose/isolate FibreBridge faults through the Event Log. Event logging is a mechanism for on-site observation of internal FibreBridge behavior such as tracing SCSI commands received over the Fibre Channel from the host and return of data and status to the host. CLI commands are case insensitive (upper and lower case allowed anywhere).
ErrorLog Diagnostic commands Set form clears ErrorLog since previous error reported. Get form shows error messages since the report was last cleared. Actions: set ErrorLog clear Information: get ErrorLog Returns: Error Logs cleared Returns: The last error code save was xx An error of type xxx was detected since last error log clearing Specific error text. IdentifyFibreBridge Enabling this option causes the Ready LED on the front panel of the FibreBridge to blink until the parameter is disabled.
7.1.4 SCSI configuration commands The SCSI ports are configured with default settings but may be customized to your specifications using the CLI commands in this section.

7.1.8 Maintenance commands The CLI commands outlined in this chapter may be used to get information or perform functions which are used in a variety of situations with the ATTO FibreBridgeTM. CLI commands are case insensitive (upper and lower case allowed anywhere).
Zmodem WARNING After a firmware image is downloaded to the FibreBridge, the image is placed into flash memory. During this time (about 30 seconds), DO NOT remove power to the FibreBridge or the flash may become corrupted.
7.2 In-band CLI using SCSI over Fibre Channel port In-band Command Line Interface (CLI) configures and manages the ATTO FibreBridgeTM 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.
➔ Characters following the NULL character are meaningless. Exhibit 7.2-1 In-band CLI 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.
8 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.
