ATTO Technology Inc. iPBridge Installation and Operation Manual
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 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).
Gigabit Ethernet (GbE) is a transmission
technology based on the Ethernet format and
protocol used in local area networks (LANs). It
provides a data rate of 1 billion bits per second
(one gigabit) as defined in the IEEE 802.3
standard.
intelligent Bridging Architecture, the engine
within ATTO FibreBridge™ and iPBridge
products, uses ATTO Data Routing Fabric
topology and ATTO Virtual Device Manager to
optimize performance. For more information see
www.attotech.com/iBA.html.

Term Definition
Btl Bus-Target-LUN: Identification for a parallel SCSI device
CHAP 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.
DP
data port
GbE port used for data movement and management
firmware 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
GbE
Gigabit Ethernet
A protocol for transferring block-level IO over Telnet networks; speed at which
data is passed over Ethernet
IETF Internet Engineering Task Force: The standards body responsible for Internet
standards such as SNMP and Telnet through a community of network designers,
operators, vendors and researchers concerned with the evolution and smooth
operation of the Internet
initiator device A component which originates a command
iSCSI Internet SCSI (Small Computer System Interface), a protocol to link data storage
facilities over the Internet or an intranet developed by the Internet Engineering
Task Force (IETF); carries SCSI commands over IP networks to facilitate data
transfers over intranets and manage storage over long distances
LED Light-emitting diode, a type of diode that emits light when current passes through
it; visible LEDs are used as indicator lights on all sorts of electronic devices

Introduction
LUN Logical Unit Number: a SCSI identifier of a device
NAS 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
SCSI Small Computer Systems Interface: a processor-independent standard for
system-level interface between a computer and intelligent devices including hard
disks, floppy disks, CD-ROM, printers, scanners, etc.
SNMP 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
Tape Window A fixed-size parameter indicating the maximum data length that can be written to
a tape in one Data Mover action; once the tape window is reached, the Data
Mover will pause until writes occur and the tape window becomes available.
TCP/IP Abbreviation for the basic communication protocols used on the Internet
including Transmission Control Protocol (TCP), Internet Protocol (IP), File
Transfer Protocol (FTP), Simple Mail Transfer Protocol (SMTP) and Telnet.

ATTO Technology Inc. iPBridge Installation and Operation Manual
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 single-
channel 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.
