ATTO Technology Inc. iPBridge Installation and Operation Manual
1 ATTO iPBridge provides storage options
The ATTO iPBridge
TM
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.
Embedded software features
• SpeedWriteTM:a performance-enhancing
capability that significantly boosts Write
performance by efficiently managing Write
commands between host and a tape device.
• Security through Virtual LANs, Access Control
Lists (ACLs) and multiple levels of password
protection
• Advanced Diagnostics include software event-
logging capability time and date stamped by the
real time clock. You can also determine
numerous status and current configuration
parameters.
• Management and monitoring through ATTO
ExpressNAV, a web-based management
application that allows all of the configurable
settings for the iPBridge to be defined, viewed
and edited; E-mail notification of errors and
Simple Network Management Protocol (SNMP)
support.
Connectivity, infrastructure solutions
The topology of a heterogeneous Storage Area
Network shown on the next page demonstrates the
critical role ATTO products play in the design and
implementation of a SAN. Whether your
application needs are data-intensive or band-
width intensive, you need to store and manage
that data and then deliver it to end-users
efficiently. ATTO products have been engineered
with the highest performance and lowest cost
available today.

ATTO Technology Inc. iPBridge Installation and Operation Manual
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.
CAUTIONCAUTION
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 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.
2 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.
Automatically configure a single target
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.
2 From the ExpressNAV main menu, click on the
Auto Target Mgt menu item on the left side of
the screen.
3 Click on the Map all devices to default target
button.
4 When the action is complete, the iSCSI Target
Management page appears. Make any
adjustments to the mapping or begin a
discovery session.
If you are prompted to restart the iPBridge, go
to the Firmware Restart page and restart the
iPBridge.
Manually configure a single target node
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.
2 From the ExpressNAV main menu, click on the
Manual Target Mgmt menu item on the left
side of the screen.
3 Click on the Device Maps link of the default
target.
4 Select the devices from the box on the right
hand side of the screen and drag to the
appropriate LUN on the left.
5 Click Submit.
If you are prompted to restart the iPBridge, go
to the Firmware Restart page and restart the
iPBridge.

8
Installation: mapping
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.
Automatically configure multiple targets
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.
2 From the ExpressNAV main menu, click on the
Automatic Target Management menu item on
the left side of the screen.
3 Click on the Map each device to its own
target button. See Exhibit 2.1-2 on page 10.
The iPBridge maps itself as a device at LUN 0.
A target name suffix is added to the iqn of each
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
When the action is complete, the screen returns
to the iSCSI Target Management page.
If you are prompted to restart the iPBridge, go
to the Firmware Restart page and restart the
iPBridge.
Manually configure multiple target nodes
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.
2 From the ExpressNAV main menu, click on the
Automatic Target Management menu item on
the left side of the screen.
3 In the iSCSI Target Management page, type
[name] in the Add an iSCSI target box
The name is a suffix appended to the standard
IPBridge iqn name. The suffix name can be up
to 24 characters.
4 Click on the device map link of your target.
5 After the next mapping page opens, drag the
boxes representing devices to the LUNs you
want.
6 Click Submit.
7 Repeat from Step 3 for each node you want to
configure.
8 If you are prompted to restart the iPBridge, go
to the Firmware Restart page and restart the
iPBridge.
