Introduction: iSCSI provides storage options

The iSCSI protocol allows storage devices such as hard drives, tape drives and libraries and CD jukeboxes to attach easily to Internet Protocol networks such as Gigabit Ethernet. The iPBridge 1500 and the ATTO iPBridge 1550 support the high throughput needs of streaming data transfers, optimizing performance and management using ATTO Technology intelligent Bridging Architecture™.

The iSCSI protocol

1 Setting up the iPBridge

The ATTO bridge family of products provides GbE-to-SCSI or Fibre Channel-to-SCSI bridges available as embeddable 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. Each product has been engineered to address specific customer needs. New capabilities are integrated into products throughout the family as much as possible, requiring only an upgrade of firmware to incorporate them into your SAN (Storage Area Network) or NAS (Network Attached Storage).

The ATTO iPBridge 1500E/D is a low cost singlechannel iSCSI-to-SCSI bridge that enables existing Direct-Attached Storage solutions to be integrated into an Ethernet network allowing IT departments to leverage existing investment in SCSI storage and Ethernet infrastructure and expertise.

The ATTO iPBridge 1550E/D is a cost-effective way of expanding your existing storage capacity without sacrificing performance. The ATTO iPBridge 1550E/D is ideally suited to the SME or for corporate IT departments seeking to expand storage requirements with minimal disruption while making existing SCSI equipment accessible over an Ethernet network to all network users.

To make sure you have the most up-to-date version of the firmware, visit the ATTO Technology website, www.attotech.com.

1.5 Connecting SCSI devices to the SCSI port

The ATTO iPBridge SCSI port connects SCSI storage devices to the network.

The SCSI port is a bus capable of supporting up to15 devices in LVD mode and each bus is capable of 40, 80 or 160 MB/sec. (Ultra, Ultra2 or Ultra3) transfer rates.

The SCSI bus auto-negotiates the appropriate sync rates with the connected devices. If slower devices are mixed with faster devices, the bus will communicate at the rate of the slowest device, thus wasting the performance capabilities of the faster devices.

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.

To connect SCSI devices to the ATTO iPBridge

1 Connect the cable from the SCSI device to the

68-pin HD SCSI port on the iPBridge.

2 Check the type of cable, cable length limit and

number of devices recommended for the port. See Exhibit 1.5-1.

Keep cable lengths as short as possible to

ensure the highest signal quality and performance. These cable lengths include the wiring inside the devices.

3 Set the IDs of the SCSI devices connected to

the bridge to a value other than 7.

Use a sequential ID starting at 0 for each

device. The SCSI port in the ATTO iPBridge has an internal factory setting ID of 7, typical for a SCSI initiator device.

To set SCSI port bus speed and transfer rates

Note

The preferred method to set parameters for the iPBridge is to use ATTO ExpressNAV. Refer to and

Cabling

Cables and devices must be chosen to maximize performance and minimize the electrical noise from the high-speed data transfers available with the SCSI protocol. Cabling and termination methods become important considerations for proper performance. SCSI cables and devices are subject to specific length and number limitations to deal with electrical problems that arise at increased operating speeds.

Cable types

Use high-quality cables rated for the type of SCSI transfers required: well-insulated SCSI cables ensure error free communications. Try to keep cable lengths as short as possible to ensure higher signal quality and performance.

Exhibit 1.5-1 Various types of SCSI operate at different speeds and require different bus lengths to support a certain number of devices.

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. If the 7-drive tower requires 1 meter of cabling to connect all of its drives, the distance from the tower to the host must be .5 meters.

Note

1.6 Configuring the iPBridge

Communicate with the ATTO iPBridge through the GbE port using ATTO ExpressNAV or Telnet or through the serial port.

The preferred method to communicate with and manage the iPBridge is through the GbE port using ATTO ExpressNAV, a GUI web-based interface. ATTO QuickNAV, a utility program,

Connecting using the GbE port

Before you begin installing the iPBridge, be sure to check or complete the following

1 If you are managing your iSCSI system across

a WAN and your system uses a firewall, be sure that the following ports are open and available:

If you are using the TCP protocol

• telnet (port 23)

• http (port 80)

• ftp (ports 20 and 21)

• iscsi (port 3260)

• iSNS (port 3705)

If you are using the UDP protocol

• ntp (port 123)

• SNMP (port 161)

2 Be sure your host system(s) is set up and

configured. Your host system can use any of three different types of cards:

• a network interface card (NIC)

• a TCP offload engine card (TOE) or

• a storage network interface card (SNIC).

3 For best performance, all cabling, network

interface cards (NICs), host bus adapters (HBAs), and network switches must be Gigabit Ethernet (GbE), and at least Cat 5e certified. Most standard offices use 2-pair wiring which is not compatible. GbE requires 4-pair wiring.

4 For best performance, support for 9014 byte

jumbo frames should be available for all switches and host iSCSI equipment.

5 Ensure that the iPBridge has access to a DHCP

server.

automatically finds your iPBridge on the network so that you can begin configuration.

You may use the Command Line Interface through the serial port or through the GbE port using Telnet.

6 Download the ATTO QuickNAV utility,

QuickNAV-windows.exe, from the ATTO website, www.attotech.com, or from the product CD.

7 Ensure the host running QuickNAV and the

iPBridge are on the same subnet.

8 Any switch in the IP SAN network must allow

UDP broadcast messages to be passed through.

9 You do not have a router between the host

running QuickNAV and the iPBridge.

10 You have the iPBridge serial number.

To find the iPBridge

1 Using at least Cat5e cable, connect the

iPBridge Ethernet port to your network.

2 Power on the iPBridge.

3 Wait approximately one minute to insure the

iPBridge obtains an IP address from the DHCP server.

4 Run the QuickNav Utility QuickNAV-

windows.exe which you previously downloaded from the ATTO website,

www.attotech.com, or from the product CD:

5 Follow the on-screen instructions. You will need

the iPBridge serial number.

6 Continue to configure and mange the iPBridge

using the ExpressNAV interface. Refer to Using

2.3 Mapping devices

SCSI devices are mapped using the designations for the SCSI bus, target and LUN. The iPBridge automatically maps all devices during startup. If you wish to change mapping you may use the CLI or the browser-based interface, ATTO ExpressNAV.

Note

To map devices, you should have a host computer connected to the iPBridge Ethernet port. Refer to page 13.

Configuring the iPBridge

By default, a host or initiator will view the iPBridge as a single iSCSI node with all available SCSI devices shown as LUNs on a single iSCSI target.

You may use multiple target mode to break the single iSCSI node into multiple nodes. Multiple target mode allows you to grant or deny access between initiators and devices as needed.

Single target mode

Single target mode is the default. Use the CLI commands or the ExpressNAV interface to map devices automatically or manually.

Note

The iPBridge automatically maps all devices on startup.

Node names

iSCSI nodes are accessed through the Ethernet ports on an iPBridge, each identified by its own IP address.

The iPBridge uses the

Use the ExpressNAV interface

The ATTO Technology ExpressNAV, a browserbased configuration tool, allows you to map devices to the SCSI ports using a web-based GUI.

ExpressNAV provides web-based interface

See on page 19.

To map devices automatically with ExpressNAV

1 From the ExpressNAV main menu, click on the

Mapping menu item on the left side of the screen.

Multiple target mode

Multiple Target Mode breaks the single iSCSI node of the iPBridge and replaces it with a much more configurable mapping scheme. This new mapping scheme allows you to 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 mapping would provide both servers access to all tapes and the media changer (single target mode).

If you configured multiple target mode, you would be able to map some devices to one server and other devices to the other server, requiring separate usernames and passwords for access.

CAUTIONCAUTION

If actual storage is mapped to more than one iSCSI target and a server has authorization for both targets, the server could show duplicate storage without any warning to the user.

If multiple target mode is enabled, the
