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™.

Term
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
GbE port used for data movement and management
data port
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

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
