1.1 ATTO iPBridge 2600 characteristics The ATTO iPBridge 2600 is a 1-Gigabit Ethernet to SCSI 1U full-rack bridge for high performance, cost effective solutions in enterprise environments. The iPBridge 2600 is a cost effective, high performance bridge using four Gigabit Ethernet ports and two independent Ultra 320 SCSI busses. Because the iPBridge 2600 provides a compact embeddable, rack or desktop solution, you can install the iPBridge in a wide range of system configurations.
Ethernet interface • The four independent 100/1000 Ethernet RJ45 data ports are labeled Ethernet ports 1, 2, 3 and 4. A separate 10/100 Ethernet standard RJ45 management port provides monitoring and management through telnet or ATTO ExpressNAV, a browser-based interface. Gb Ethernet cables must be at least CAT-5E certified. Serial interface The RS-232 serial port provides support for remote monitoring and management through a command line interface. It is set at the factory at 115,200 bps.
2 Installing the iPBridge If you have not already completed the instructions on the Quick Start page packed with your iPBridge, use the following instructions to install the iPBridge. Unpack the packing box; verify contents Discover the IP address • The iPBridge Note the serial number of your iPBridge, located on the bottom of the unit, for later use: ______________________________ 1 From the CD supplied with your iPBridge, run the QuickNav Utility QuickNAV-windows.
Exhibit 2.0-1 Install the iPBridge into a rack using the brackets provided.
2.1 Target management Storage devices are mapped using the designations for the iSCSI LUN. The easiest way to map devices is to use the Automatic Target Management feature in the ATTO ExpressNAV interface. CAUTION Changing the device map can affect the host’s view of devices and your application configuration. To map devices, you must connect the devices to one of the iPBridge SCSI ports.
Multiple target nodes Multiple targets allow you to create a more configurable mapping scheme which can segregate storage into different iSCSI nodes within the iPBridge, with each iSCSI target having its own set of access criteria. For example, if you have two servers and a library with four tapes and a media changer, the default nodes would provide both servers access to all tapes and the media changer (default target mode).

2.2 Additional configurations Additional configurations to improve usability and security are available on the iPBridge. Use ATTO ExpressNAV or the Command Line Interface. Set the Real Time Clock Before proceeding you should set the Real Time Clock. You can set the time automatically by using the Simple Network Time Protocol (SNTP). SNTP is enabled by default. 1 2 3 4 Note The iPBridge must remain powered on for more than 24 hours to ensure the date and time are set.
Enhance performance Default settings are appropriate for most systems. However, you may wish to enhance performance using the ATTO ExpressNAV user interface. 1 If you are not already in the ExpressNAV GUI, type the IP address of your iPBridge, as found in Discover the IP address on page 5, in a standard browser and press Enter. Click through the menu items at the left side of the screen to view settings and possible changes.
3 Remote system monitoring You may set up the iPBridge to send notifications when certain events occur. Use the Remote Management page of the ExpressNAV interface to send information about the operation of the iPBridge. CLI commands may be used to set up remote monitoring. Refer to Diagnostic commands on page 39. You may designate the person receiving notification of conditions and the level of severity which prompt notification.
Exhibit 3.0-1 The E-mail messages sent by the iPBridge follow this format. Subject: [The Type of Event that Occurred] Message Body: This is a status message from [BridgeName]. Identifying information as well as the most recent entries from the event log appear below.
4 Updating firmware Several processors control the flow of data in the ATTO iPBridge. The firmware to control these processors can easily be upgraded in the field using the ATTO ExpressNAV interface or the PUT command from an FTP connection. The ATTO ExpressNAV method is preferred. Preliminary steps 1 2 The iPBridge firmware is distributed as a compressed .zip file and can be obtained from the ATTO Technology, Inc. web site at www.attotech.com or from the CD included with your iPBridge. Uncompress the .
18 Firmware update
5 Troubleshooting If it is clear that a particular component system is at fault in a problem situation, go directly to that component. If it is not clear, the best approach is to troubleshoot using the inside-out method. You may check on the status of your iPBridge using the ExpressNAV interface. Refer to ATTO ExpressNAV interface on page 25 to see which pages may contain the information you need.
Check iPBridge product versions For a current list of required updates, visit www.attotech.com. 2 Click on the Status page and view the information on the product version. 1 3 If an update is needed, download the update from www.attotech.com. If you are not already in the ExpressNAV GUI, type the IP address of your iPBridge, as found in Discover the IP address on page 5, in a standard browser and press Enter. Refer to Updating firmware on page 17.
Checking the iPBridge internal configuration Verify that the SCSI devices are mapped properly. Check in the ATTO ExpressNAV interface or use the routedisplay iSCSI command to show mappings. If devices do not appear, power down the iPBridge and power back on. Refer to Mapping devices: NDMP on page 13, Mapping devices: iSCSI on page 15 and Mapping commands on page 57.
4 Verify that the hosts are running the recommended driver and firmware level for the iSCSI host adapter or NIC vendor. 5 Verify that the hosts and the iPBridge are using the same port number to communicate via iSCSI. The default port number for the iPBridge is 3260. Refer to iSCSIPortNumber on page 55. 6 7 Make sure the host adapter/NIC is configured to log into the iPBridge. Some iSCSI host adapters do not re-login upon reboot or unplug/replug event without marking a check box.
Performance issues If the host is not getting the performance it should, check the following items. Checking the LAN/WAN 1 Checking SCSI devices 1 Verify that the devices are running at their highest possible SCSI speed. Refer to SCSI configuration commands on page 47. Mixing SE and LVD devices on the same SCSI bus forces the speed of the bus to SE, thus slowing faster LVD devices. The iPBridge cannot accelerate an already slow device.
Checking the host system The faster the host, the faster your transfer times are. The work flow goes only as fast as the slowest connection in the host system, so transferring data from an IDE drive, 100Mb connection, a DLT 4000, a high speed RAID volume across the country, or other applications, slows the system no matter how fast everything else is in the system. 1 Verify that the iSCSI storage adapter or NIC is connected to the fastest PCI bus connector supported by the adapter or NIC.
6 ATTO ExpressNAV interface The easiest way to communicate with the ATTO iPBridge is to use the browser-based interface. ATTO ExpressNAV. This chapter provides additional information about the interface and how to use it. The recommended management tool for the iPBridge is ATTO ExpressNAV, a web-based interface which may be accessed from any web browser that supports the latest standards for XHTML 1.0 and CSS1.

Appendix A ATTO Bridge family The ATTO bridge family of products provides GbE-to-SCSI or Fibre Channel-to-SCSI bridges available as Compact PCI (CPCI) boards, stand alone enclosures that can be fitted for rackmount integration, or desktop units, depending on the model and your needs. The ATTO iPBridge and ATTO FibreBridge family of products share common configuration options and functions to provide the most versatile connectivity options available.
FibreBridge products Product features Number of FC ports FC interface Data transfers Number of SCSI ports SCSI interface Sustained data transfer rate (MB/sec.
Appendix B Cabling Additional information to physically connect ports to devices and to your SAN. SCSI cabling Examples The SCSI specification limits total bus cable length for single-ended SCSI in a non-UltraSCSI environment to 3 meters (combined length of both internal and external cable lengths). In an UltraSCSI workgroup environment with a 7drive tower, you are limited to 1.5 meters between the host and the tower, including the cabling for the tower.
Each SCSI bus auto-negotiates the appropriate sync rates with the connected devices. If slower devices are mixed with faster devices, the bus communicates at the rate of the slowest device, thus wasting the performance capabilities of the faster devices. Connect slower devices to one SCSI port and connect faster devices to the other port. The iPBridge supports a wide variety of SCSI storage devices including stand-alone drives, removable drives, JBODs, RAIDs, tape, CD and DVD drives, changers and libraries.
