ATTO Technology Inc. iPBridge Installation and Operation Manual
1 ATTO iPBridge 2700 provides storage options
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
