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

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 sec rets
(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
