The ATTO iPBridge
TM
 
2700C/R/D iSCSI to Fibre Channel bridge offers an affordable opportunity to 
transform Fibre Channel 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):  
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. 
iSCSI encapsulates SCSI packets in TCP, then 
routes the packets using IP. Block-level storage 
data is transported over IP networks using SCSI 
commands. Data may be accessed from virtually 
anywhere that can be reached through the 
Internet, eliminating physical boundaries. 
iSCSI implements SANs cost-effectively and 
manages SANs using technologies that you 
already have and understand such as SCSI, IP, 
Ethernet and SNMP, allowing you to take 
advantage of these interoperability benefits. 
iSCSI also lowers the investment cost of adding 
new servers to a SAN for both primary storage 
and backup applications.
ATTO iPBridge 2700 features, benefits
The iPB2700 is a cost effective, high performance 
bridge using four Gigabit Ethernet ports and two 
independent 4-Gb Fibre Channel buses. 
The iPBridge comes in two form factors: 
•  4U cPCI embeddable circuit board or blade, 
designated as the iPBridge 2700C
•  a rack mount / desktop version (13”d x 19”w x 
1U) designated as the iPBridge 2700R/D 
Because the iPBridge 2700C/R/D provides a 
compact embeddable, rack or desktop solution, 
you can install the iPBridge in a wide range of 
system configurations. Uniquely designed to 
support the high throughput needs for 
applications that require streaming data transfers 
(data backup), the iPBridge optimizes 
performance by using ATTO Technology 
intelligent Bridging Architecture. 
•  4 independent 100/1000 GbE RJ45 Ethernet 
ports to 2 optical SFP independent 4-Gb Fibre 
Channel ports
•  Near wire speed (99.35%) per GbE port
•  Auto negotiates to 4/2/1 Gb Fibre Channel
•  Full support for direct connect to F-port fabric 
switches, FC-AL, PLDA, public loop login and 
iSCSI protocol 1.0
•  Available as embedded board-level or 
desktop/rack mount enclosure
•  intelligent Bridging Architecture, the engine 
within ATTO iPBridge™ products, uses ATTO 
Data Routing for optimized performance
•  PCI-X v1.0 internal bus
•  Fabric topology and ATTO Virtual Device 
Manager to optimize performance.
