applications
The LSI21002 PCI-to-Ultra2 SCSI
dual channel host adapter supports a
wide variety of Fast and Ultra SCSI devices.
OVERVIEW
The LSI21002 dual channel PCI-to-Ultra2 SCSI host adapter board by
LSI Logic is designed for systems using high performance disks as well as
supporting a wide variety of Fast and Ultra SCSI devices. By using the
LSI53C896 dual channel PCI-to-Ultra2 SCSI controller chip to directly interface
to the PCI and SCSI buses, the LSI21002 is able to provide the high reliability
and cost effectiveness of a single-chip design. By having two complete and
separate SCSI channels, the LSI21002 can dedicate one channel, with full
connectivity, to high performance devices and the other channel, also with
full connectivity, to legacy SCSI devices.
Matching the performance of the 32-bit PCI bus to two independent SCSI
channels, the LSI21002 host adapter provides up to 120 MBps aggregate
SCSI throughput. With LSI Logic鈥檚 LVDlink
鈩?/div>
(Low Voltage Differential) and
TolerANT
鈩?/div>
technology, the LSI21002 provides unmatched performance,
device connectivity and signal reliability. LVDlink is LSI Logic鈥檚 implementa-
tion of the Universal
Low Voltage Differential standard. At last, one board provides a powerful
dual channel, scalable, multi-tasking interface for high performance SCSI
disk drives, CD-Rs, CD-RWs, scanners, interconnect, and other single-ended
or LVD SCSI devices. The dual channels increase to connectivity to up to 30
devices without utilizing an additional PCI slot or PCI load.
Designing systems with the LSI21002 is easy with one channel dedicated
to high performance LVD devices and the second dedicated to supporting
single-ended legacy devices. Or both channels can be used to support single-
ended devices.
