SCSI Performance
SCSI Performance
LSI PCI Express host bus adapters provide high-
availability and scalability, and are compatible
with the newest workstations and servers.
The LSI20320IE features internal and external
Ultra320 SCSI channels that allow a data transfer
rate of 320MB/s. Supporting up to 15 devices
for a flexible, fault-tolerant solution, this adapter
is ideal for entry-level to enterprise servers
and high-performance workstations with PCI
Express slots.

LSI HBAs provide outstanding I/O performance
while allowing extremely high host processor
efficiency. The LSI20320IE delivers the speed and
bandwidth required by today’s data intensive
storage applications, such as data mining, inter-
net, email, graphics, audio editing, database
servers, scientific simulation and video streaming.

The PCI Express Advantage
The PCI Express host interface employs high-
speed serial link technology, an improvement
over the PCI and PCI-X buses, which operate on
32- and 64- bit parallel buses. Performance
advantages over PCI-X are seen from the huge
speed serial link technology, an improvement
over the PCI and PCI-X buses, which operate on
32- and 64- bit parallel buses. Performance
advantages over PCI-X are seen from the huge
increase in data throughput and the dedicated
point-to-point link for each device. With PCI
Express throughput of 2.0GB/s full-duplex,
performance will be limited only by the U320
SCSI bus.

The LSI20320IE also utilizes Fusion-MPT
(Message Passing Technology) architecture that
improves performance with thinner drivers (up
to 100,000 I/Os per sec) while adding value and
flexibility at the firmware level. Common drivers
for each OS greatly reduce the integration and
testing effort for systems already qualified using
Fusion-MPT powered devices.

Most Reliable Host Bus and SCSI
Signal Quality
Signal Quality
The LSI20320IE not only moves data blazingly
fast, it also insures unmatched data reliability and
signal quality. With LSI TolerANT™ technology,
this adapter improves data integrity through
active negation on the drivers and input filtering
on receivers of the controller. LSI also features
SureLINK domain validation technology, which
intelligently tests the network before completing
negotiation. It verifies that all devices are able to
communicate at the negotiated SCSI transfer
