Internet SCSI technology (iSCSI) is one of today’s 
fastest growing storage networking protocols. 
iSCSI utilizes Ethernet networks to allow users to 
reap the benefits of networked storage, such as 
increased availability and scalability. However, this 
presents a problem for organizations interested in 
migrating to iSCSI but have already invested thou-
sands of dollars in SCSI-based storage.  ATTO 
iPBridges help resolve this issue by offering iSCSI 
connectivity to native SCSI devices, extending the 
useful life of SCSI devices while eliminating the 
need to purchase costly new storage.  
 
The ATTO iPBridge

TM

 1550D provides a simple 

and cost-effective way to add iSCSI connectivity to 
Ultra320 SCSI devices. The 1550D is available as 
a compact desktop unit which provides near-wire 
speed throughput, allowing SCSI storage to oper-
ate at near-native speeds. Initial installation and 
configuration is a quick and painless task due to 
the ExpressWizard configuration assistant, which 
helps optimize the bridge for specific application 
needs by asking a series of basic questions. Man-
agement of the bridge is simplified with Express-
NAV, ATTO’s web-based management GUI which 
provides an easy interface to configure, manage 
and diagnose ATTO iPBridges.   
 
The iPBridge 1550D offers broad market accep-
tance through ISV certifications and support for 
leading iSCSI protocols, and is the first choice of 
organizations that require cost-effective iSCSI con-
nectivity without sacrificing performance.
