1 ATTO iPBridge provides storage options
The ATTO iPBridgeTM 2600 iSCSI to SCSI bridge offers an affordable opportunity to transform SCSI
storage into network-enabled addressable devices, creating scalable solutions for an iSCSI SAN.
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 ATTO
iPBridge supports the high throughput needs of
streaming data transfers, optimizing performance
and management using ATTO Technology
intelligent Bridging Architecture™.
Gigabit Ethernet (GbE) is a transmission
technology based on the Ethernet format and
protocol used in local area networks (LANs),
providing a data rate of 1 billion bits per second
(one gigabit) as defined in the IEEE 802.3
standard.
The iSCSI protocol increases the capabilities and
performance of storage data transmission by
transmitting data over local area networks
(LANs), wide area networks (WANs), or the
Internet, providing location-independent data
storage and retrieval to enhance current and future
Storage Area Networks (SANs).
The iSCSI protocol enables complete SAN
solutions based on a Gigabit Ethernet network
infrastructure. iSCSI is a logical SAN alternative
to direct-attached storage where simplicity,
flexibility and price/performance are critical.
Data may be accessed from virtually anywhere
that can be reached through the Internet,
eliminating physical boundaries.
iSCSI also lowers the investment cost of adding
new servers to a SAN for both primary storage
and backup applications.

Installation
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. To access mapped
devices over Ethernet, you must have a host
computer connected to one of the iPBridge
Ethernet data ports.
You have two options to map devices:
1
2
The default is set up as a single target node in
which a host or initiator views the iPBridge as a
single iSCSI node with all available devices
shown as LUNs on a single iSCSI target.
You may set up multiple target nodes which
allow greater flexibility to grant or deny access
between initiators and devices as needed.
If you divide the default single target node into
multiple target nodes, you must set up access to
each node separately.
See Exhibit 2.1-1 on page 9 to see the difference
between single target node and multiple target
nodes.
Target names
Each iSCSI target node accessed through the
Ethernet port on an iPBridge is identified by a
unique world-wide iSCSI-qualified name. This
format references the iPBridge serial number and
target node name:
iqn.1995-12.com.attotech:ipbridge:
serialnumber <targetname>
Default target node
The default target is set as a single target with
Access Control (ACL) disabled and CHAP
authentication disabled. The default target node
cannot be deleted. The iPBridge maps devices
automatically although you can map devices
yourself.
If you are prompted to restart the iPBridge, go
to the Firmware Restart page and restart the
iPBridge.

hand side of the screen and drag to the
appropriate LUN on the left.
Click Submit.
If you are prompted to restart the iPBridge, go
to the Firmware Restart page and restart the
iPBridge.
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).
If you configure multiple target nodes, you are
able to map some devices to one server and other
devices to the other server, requiring separate user
names and passwords for access using various
methods including Access Control Lists, iSNS
and CHAP authentication. Consult with your
network administrator and refer to Exhibit 2.1-1,
iSCSI commands on page 51 and the Glossary
on page v of the Appendix.
Note
If you map actual storage to more than one
iSCSI target and a server has authorization for
both targets, the server could show duplicate
storage without any warning.

device such as
vendorid-devicename-xxx
•
•
vendorid is the device vendor ID
devicename is the device’s inquiry device
name.
• xxx is a device index

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. For example a
recipient with a critical severity level only
receives critical messages and not warning
messages.
E-mail notification
E-mail notification using SMTP (Simple Mail
Transfer Protocol) allows the iPBridge to send an
E-mail message to you, a network administrator
or other users when certain events occur:
•
critical and warning temperature conditions
•
critical and warning voltage conditions
•

The severity level can be all, warning, critical
or none.
•
All means warnings, critical events and
informational messages are sent.
•
Critical means only critical event notifications
are sent.
•
Warning means only warnings and critical event
notifications are sent.
•

When an event occurs that warrants E-mail
notification, the iPBridge scans each of its ports
until the E-mail is sent successfully. Each attempt
takes one minute. The E-mail function only sends
messages; it cannot respond to a rejection by a
server for an invalid address.
Each E-mail is time stamped when it leaves as
part of the SMTP header information.

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. You may also
look for information by using the diagnostic CLI
commands, enumerated in Diagnostic commands on
page 39, in the Advanced page of the ExpressNAV
interface, or by using the CLI directly (refer to CLI
provides ASCII-based interface on page 31.)
To start and use the ExpressNAV interface, including
how to access the version information, refer to ATTO
ExpressNAV interface on page 25.
Inside out method
To troubleshoot using the inside out method, begin with the device(s) connected to the iPBridge first, then work
your way out.
•
SCSI devices
• iPBridge SCSI ports
• iPBridge internal configuration
• iPBridge Ethernet/IP ports
• LAN/WAN
• Ethernet host adapter or NIC in host
• iSCSI OS driver
• OS
• Application
Check the host event log
Check the event log on the host. Look for the most
recent entries and determine what could be causing a
problem, then go to that event and continue
troubleshooting.
Check the iPBridge event and trace logs
Check the iPBridge event log through the CLI. Refer
to Diagnostic commands on page 39. Look for the
most recent entries and determine what could be
causing a problem. Then go to that event and continue
troubleshooting.
Visually inspect LEDs
Light Emitting Diodes (LEDs) are located on both
sides of the iPBridge
Refer to LED indicators on page 4 and Exhibit 1.1-1

Checking SCSI devices
1
3
2
Check the SCSI device power. Make sure the
devices are powering up.
3
Watch the drive lights before, during, and after
startup. Many drives have term power lights
that should be on before startup and turn off
when system boots.
4
Verify the external terminator is the correct type
and does not have damaged pins.
5
Check cable integrity. Check the cables for
solid connections. Make sure they are screwed
down. Inspect cable ends for bent pins.
6
If termination is correct, and the problem
persists, try drives one at a time with different
cables, adding drives and cables until the
problem occurs. This helps pinpoint the drive or
cable causing the problem.
Check with the manufacturer of SCSI device(s)
for further troubleshooting methods.
If SCSI devices appear to be working, move on to
the iPBridge SCSI port section.
Checking the iPBridge SCSI ports
Check the internal cabling of the SCSI device.
LVD SCSI cable lengths are limited to 12.5
meters. Longer cable lengths can cause
problems. Internal cabling is also considered
when calculating total cable length. For details,
refer to Cabling on page iii.
Check SCSI devices to make sure they are all
set to different SCSI IDs.
By default, the iPBridge SCSI ports use SCSI
ID 7 so drives should use IDs 0 through 6 and 8
through 15.
7
If no devices appear, re-check SCSI cables and
termination. If garbage information appears,
the problem is most likely a bad SCSI cable or
termination.
4
Some older SCSI devices improperly negotiate
with the iPBridge SCSI port. If older devices are
not showing up, contact your service
representative.
5
If all devices appear, invoke the ScsiTargets
command several times on each SCSI port to
verify that the devices can be seen. If devices
disappear then appear again, the problem is
most likely a SCSI cable. For information on the
ScsiTargets command, refer to SCSI
configuration commands on page 49.
If all devices appear and remain, move to the
iPBridge internal configuration section.
When changing any setting on the iPBridge the
configuration must be saved by using either the
saveConfiguration CLI command or through the
ATTO ExpressNAV interface.
Checking the serial port
1
•
Verify you have the correct settings and that
your terminal is configured to:
Baud rate: 115200
•
Data bits: 8
1
Verify the iPBridge has its termination set
properly. By default, termination is enabled.
•
Stop bits: 1
2
Either through the ATTO ExpressNAV or CLI,
perform a SCSI bus scan on each SCSI port.
•
Parity: off
•
Flow control: None
Refer to SCSI configuration commands on
page 49.
2
Verify that your serial cable is less then two
meters in length.
20
Troubleshooting
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.
When changing any setting on the iPBridge, the
configuration must be saved by using either the
saveConfiguration CLI command or through the
ATTO ExpressNAV Restart page.
Checking iPBridge Ethernet ports
1
Check Ethernet cable integrity. Check the
cables for solid connections. Cat5 cable can
cause connection issues with Gigabit Ethernet.
Cat6 cable is the best cabling for the iPBridge.
2
Verify the IP address, subnet mask, and
gateway are properly set on each data port on
the iPBridge for your network environment.
Refer to Getting an IP address on page 10.
3
Verify that the Ethernet speed is set to auto:
invoke the get EthernetSpeed all command,
check the Ethernet page of the ATTO
ExpressNAV interface, or check the LED link
lights to determine if the Ethernet speed is
correct.
4
Determine if the iPBridge is set to get its IP
information from a DHCP server. If so, verify
that the DHCP server has available IP
addresses. Refer to Getting an IP address on
page 10.
5
Verify that each used Ethernet port on the
iPBridge can be pinged from the desired host.
Refer to Ping on page 52.
If the host cannot ping the iPBridge ports and
the iPBridge ports are properly configured,
continue to the Local Area Network/Wide Area
Network section, Checking the LAN/WAN on
page 21.
switch/host at the desired speed. You may
have to force the host/switch or the iPBridge to
the desired speed.
8
Verify that the host is logging into the iPBridge
correctly by viewing the Connections page
and determining if there a “session open”
status.
9
Verify that you are using the correct log in
procedure for your initiator. For example: When
connecting using the Adaptec initiator, the log
on screen requests the iPBridge iqn (iSCSI
qualified name). If left blank, Adaptec cannot
log in. Enter “iSCSI” into this field for auto iqn
discovery.
When changing any setting on the iPBridge the
configuration must be saved by using either the
saveConfiguration CLI command or through the
ATTO ExpressNAV interface.
Checking the LAN/WAN
1
Verify that the switch/switches are segmented
properly so that hosts and the iPBridge have
access to each other.
2
If there are routers involved in the setup, make
sure the IP addresses and/or MAC addresses
of the iPBridge are allowed through the router.
3
Verify that the switch can see the iPBridge on
the port(s) in question. Refer to your switch
vendor’s guide for more information.
Checking the iSCSI Host Adapter or NIC
iSCSI host adapters appear as a type of Storage
Controller to the host OS, not as a standard NIC. These
adapters usually have hardware acceleration to offload
the TCP processing from the host. Configuration of
these adapters is usually done through the vendor’s
own utility and not through the OS itself.
NICs come in two types: accelerated and unaccelerated. Accelerated NICs use some hardware to
offload some of the TCP processing from the host. Unaccelerated NICs make the OS do all TCP processing.
To check the iSCSI host adapter or NIC
Verify that each port on the iPBridge can ping
each desired host. Refer to Ping on page 52. If
the iPBridge cannot ping the host, continue to
Checking the LAN/WAN on page 21.

ATTO Technology Inc. iPBridge Installation and Operation Manual
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.
Some older switches cannot autonegotiate
between the host and the switch properly. You
may have to force the host or switch to the
desired speed.
For a NIC using an OS iSCSI driver, continue to the
iSCSI OS driver section.
5
If using DHCP, verify that the DHCP server is
assigning the correct IP information to the host.
Refer to Ethernet Port Configuration on page
23.
6
Verify that the NIC is configured with the correct
IP information.
7
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.
8
Check cable integrity. Check the cables for
solid connections. Make sure they are plugged
in properly. Inspect cable ends for broken clips
and improper wiring.
Checking the Operating System
1
Verify that the OS has the required service
packs or patches installed. If not, obtain the
proper service packs and patches and install
them.
2
Some iSCSI host adapters and iSCSI OS
drivers do not always automatically find new
targets when plugged in or when forced to
rescan. Reboot the hosts.
3
Check if the vendor has a new driver. If so,
install it.
Checking the iSCSI OS driver
This section is for hosts using a driver that allows the
OS to talk to iSCSI targets via a NIC, not an iSCSI
storage adapter.
1
A PC using an iSCSI storage adapter and an
iSCSI OS driver might not work correctly on the
same machine. Check with the vendors to
make sure they are compatible.
2
Verify that the PC has the latest iSCSI driver as
well as the required service packs and patches.
Check with the iSCSI OS driver vendor for more
information.
1
Verify that the application is running the latest
device drivers for the devices connected to
iPBridge. If not, get the latest device drivers and
install them.
3
Verify that the iSCSI OS driver has started.
Look under Device Manager for Windows or
lsmod for Linux.
2
Verify with the application vendor if the iSCSI
technology is supported on the version of the
application being used.
4
Verify that the iSCSI OS is still looking for the
iPBridge at the right IP address.
Checking the applications

Troubleshooting
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.
Refer to Connecting SCSI devices to SCSI
ports on page iii of the Appendix.
2
1
Verify that the SCSI port configuration is set to
the highest speed using the ATTO ExpressNAV
interface or CLI. Refer to SCSI configuration
commands on page 47.
The iPBridge SCSI port speed, wide
negotiation, and sync negotiation settings all
affect the speed of the port. By default, these
settings are set for optimal speed.
2
9k frame size is the current optimized frame
size for the iPBridge. smaller frame sizes cause
a decrease in performance. Many switch and
router vendors do not support the larger frame
size of 9k or 16k.
2
Verify that the SCSI devices are equally
distributed between the SCSI ports. Refer to
Alternative interface options on page 33.
Optimal performance is seen when only two
high-speed SCSI devices are connected to
each SCSI port.
3
Verify that the data ports are set to auto
negotiate or forced to 1000 Mbs. Refer to
Ethernet Port Configuration on page 23.
2
Verify that the MTU size is set to optimal setting
for the LAN/WAN environment.
Refer to Ethernet Port Configuration on page
23. The current optimized frame size for the
iPBridge is 9k. Smaller frame sizes cause a
decrease in performance.
3
Verify that the iPBridge TraceLog feature is
disabled. Tracelog tracks certain events that
occur in the iPBridge. With this log enabled,
performance suffers.
Refer to Diagnostic commands on page 43.
23
ATTO Technology Inc. iPBridge Installation and Operation Manual
Verify that packets are not being dropped along
the LAN/WAN. Many utilities track packet
activity and switch statistics.
Checking Ethernet Host Adapter or NIC
Ethernet Storage Adapters generally outperform
accelerated NICs and un-accelerated NICs by
offloading most of the processing from the host.
An accelerated NIC provides some offloading, but still
requires a host OS iSCSI driver, making the host spend
more CPU cycles.
An un-accelerated NIC does not offload anything so
the CPU must do much of the processing.
To check the Ethernet host adapter or NIC
1
Verify that the adapter or NIC is sent to autonegotiate or forced to 1000 Mbs.
2
Set the MTU size to the largest MTU size
supported in the LAN/WAN. Refer to Ethernet
Port Configuration on page 23.
Checking iPBridge Ethernet ports
1
Verify that each associated port in the IP SAN
is configured for 1000Mbs.
IP SAN traffic should be segmented so that it
does not interfere with the main LAN network
traffic.For better performance, the IP SAN
should be on its own set of hardware.
Verify that the proper terminator is being used.
An SE terminator forces the SCSI bus to SE
speeds.
Checking iPBridge SCSI ports
Verify that the MTU size is set to optimal setting
for the LAN/WAN environment. Refer to
Ethernet Port Configuration on page 23.
9k frame size is the current optimized frame
size for the iPBridge. smaller frame sizes cause
a decrease in performance. Many switch and
router vendors do not support the larger frame
size of 9k or 16k. Set the maximum transfer
size to the most efficient size for the intended
target(s). For many tape drives, 64k is the
optimal setting.
Checking the applications
Some applications can be configured to change
transfer sizes. Configure the application for the
optimal size for the particular SCSI device(s)
connected to the iPBridge.
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.
If the adapter supports PCI-X, place the
adapter in a PCI-X slot. If one is not available,
the host might not achieve the optimal
performance capable from the adapter.
Even placing a PCI-X adapter into a 64 bit 66
MHz slot loses performance. Some adapters
adjust clock speed depending on the speed of
the PCI slot into which they are plugged.
2
The host OS disk and swap disk/partition/file
should be on a high speed drive such as a SCSI
drive to minimize the time needed to access the
host’s virtual memory.
The more memory a system has, the less time
it spends accessing virtual memory (hard drive
space).
Checking the Operating System
If possible, eliminate swap space and virtual drives
which require large amounts of system memory.
However, the OS might not allow the elimination of
swap space. An OS set to run many kinds of different
servers spends much of its CPU cycle on other
operations, thus slowing down performance.

If a list of all available commands does not
appear on the screen, review the steps in this
section, check the cable, or contact service
personnel until the problem is solved.
If you have difficulty using the serial port, verify
that you have the correct settings and that your
serial cable is less then two meters in length.
Use Telnet
Up to three Telnet sessions can be conducted
simultaneously. A serial port session can use the
CLI while Telnet sessions are open. Whichever
session issues the first “set” CLI command can
continue to issue set commands, while the other
sessions can only issue “get” commands or
display information. Once a connection is
established, refer to CLI provides ASCII-based
interface on page 31.
1
Connect to the iPBridge from a computer on the
same Ethernet network.
2
Start a Telnet session.
Note
There is more than one way to connect to the
iPBridge using a telnet program.Your telnet
program may operate differently than in the
following instructions.
3
At the telnet prompt, issue the open command
where x.x.x.x is the IP address of the iPBridge.
telnet > open x.x.x.x

Interfaces
7.1 CLI provides ASCII-based interface
The command line interface (CLI) provides access to the ATTO iPBridge Services through a set of ASCII
commands. CLI commands may be entered while in CLI mode.
iPBridge Services provide configuration and
monitoring for the iPBridge. CLI commands may
be entered while in CLI mode or on the
ExpressNAV interface Advanced CLI page.
•
•
CLI commands are context sensitive and
generally follow a standard format
[Get | Set] Command [Parameter 1 |
Parameter 2]
Responses to set commands are either an error
message or Ready. *. The asterisk indicates
you must use a SaveConfiguration command
to finalize the set command.
SaveConfiguration asks if you want to restart
the system or not.
followed by the return or enter key
•
CLI commands are case insensitive: you may
type all upper or all lower case or a mixture.
Upper and lower case in this manual and the
help screen are for clarification only.
•
Commands generally have three types of
operation: get, set and immediate.
•
The get form returns the value of a parameter or
setting and is an informational command.
•
Responses to get commands are specified in the
Results field for each command, followed by
Ready.
The set form is an action that changes the value
of a parameter or configuration setting. It may
require a SaveConfiguration command and a
restart of the system before it is implemented.
The restart can be accomplished as part of the
SaveConfiguration command or by using a
separate FirmwareRestart command. A
number of set commands may be issued before
the SaveConfiguration command.
Commands which do not require a
SaveConfiguration command are immediately
executed.
Responses to commands are either an error
message or data results followed by Ready.
For an example of a typical CLI command and
response, see Exhibit 7.1-2 on page 32.

Appendix
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. 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.
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.
Note
UltraSCSI is very sensitive to SCSI bus noise,
cable distances and the number of devices
connected on the SCSI bus. Carefully connect
your devices when working with UltraSCSI.
Exhibit 0.0-1 Various types of SCSI operate at different speeds and require different bus lengths to support
a certain number of devices.

Connecting SCSI devices to SCSI ports
ATTO iPBridge SCSI ports connect SCSI storage
devices to the network. Each SCSI port is
completely independent from the other SCSI port.
Each SCSI port is a bus capable of supporting 15
devices and each bus is capable of 40, 80, 160 or
iii
ATTO Technology Inc. iPBridge Installation and Operation Manual
520 MB/sec. (Ultra, Ultra2, Ultra 160 or Ultra
320) transfer rates.
You may use externally provided striping
software to create a RAID 0 group that includes
devices from both SCSI busses to increase overall
performance.
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.
1
Connect the cable from the SCSI device to a
VHDCI SCSI port on the iPBridge.
2
Check the type of cable, cable length limit and
number of devices recommended for the port.
See Exhibit 0.0-1.
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.
Note
The entire SCSI bus operates at the speed of
the slowest device on that bus. If you wish to
mix devices of different SCSI speeds, place
the devices on separate busses. That is, put
the slower devices on iPBridge 2500 SCSI bus
0, and the faster devices on iPBridge 2500
SCSI bus 1. Each bus is independent so each
can operate at different speeds.
Terminate the SCSI bus after the last device. The
iPBridge is terminated internally.
Ethernet connections
Use at least Cat 5e cable to connect the Ethernet
ports to your network.
Note
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.
•
If you are using the UDP protocol
•
•
For best performance, support for 9014 byte
jumbo frames should be available for all switches
and host iSCSI equipment.
Before you begin installing the iPBridge Ethernet
ports, be sure to check or complete the following:
•
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:
telnet (port 23)
•
http (port 80)
•
ftp (ports 20 and 21)
•
iSCSI (port 3260)
ntp (port 123)
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/IP offload engine card
(TOE), or a storage network interface card
(SNIC).
•
The ATTO driver file from the CD included
with your iPBridge or from the ATTO
website, www.attotech.com, is installed on
your host.
•
The switch has been configured to forward
UDP broadcast messages.
•
The minimum requirement for Windows-based
browsers is Internet Explorer 5.5 or Netscape
Navigator 6.2. The minimum requirement for
Macintosh browsers is Internet Explorer 5.2 or
Safari 1.2.
•
Ethernet speed defaults to auto; the iPBridge
determines the speed and set other parameters
based on the speed.
If you are using the TCP protocol
•
iSNS (port 3705)

Definition
Access Control List: characteristic of an iSCSI target node on ATTO iPBridges
whereby iSCSI initiators allowed access to that target node are included on a list of
permitted initiators.
PCs and servers send (broadcast) information out through an Ethernet domain.
Switches and routers may connect domains, but may not share information across
domains.
Challenge-Handshake Authentication Protocol: If CHAP is enabled, the target
requires the initiator to negotiate CHAP authentication using the CHAP secrets
(passwords). An initiator may reject this negotiation.
As defined in RFC 2131, a protocol which assigns IP addresses to devices on a
local area network. The iPBridge is set up by default to request an IP address from
the DHCP server.
Software stored in read-only memory (ROM) or programmable ROM (PROM);
firmware is often responsible for the behavior of a system when it is first switched
on

representation of a single iSCSI initiator or iSCSI target. Each iSCSI target node
accessed through the Ethernet port on an iPBridge is identified by a unique world-wide
iSCSI-qualified name.
Logical Unit Number: an identifier of a device
Network Attached Storage: storage elements connected to a network to provide file
access services to computer systems; an NAS Storage Element includes an engine
to implement the file services and one or more devices to store data; NAS elements
may be attached to any type of network; an NAS host system uses a file system
device driver to access data and NAS systems interpret these commands to
execute the necessary internal file and device I/O operations
Small Computer Systems Interface: a processor-independent standard for systemlevel interface between a computer and intelligent devices including hard disks,
tape, floppy disks, CD-ROM, printers, scanners, etc.
Simple Network Management Protocol: a standard for monitoring and managing
systems and devices in a network; data is defined by a MIB; functions supported
include the request and retrieval of data
Simple Network Time Protocol: uses a server to set the time and date over the
Ethernet port.
