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
LSI22320SE features two external Ultra320 SCSI
channels that allow an aggregate SCSI speed
of 640MB/s. Supporting up to 30 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 LSI22320SE delivers the speed
and bandwidth required by today’s data
intensive storage applications, such as data
mining, internet, 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 PCI and PCI-X, which operate on 32- and
64-bit parallel buses. Performance advantages
speed serial link technology, an improvement
over PCI and PCI-X, 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 2.0 GB/s full-duplex, performance
will be limited only by the U320 SCSI bus.

The LSI22320SE 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.

Signal Quality
Signal Quality
The LSI22320SE 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 technol-
ogy, which intelligently tests the network before
completing negotiation. It verifies that all devices
are able to communicate at the negotiated
