OVERVIEW
Breakthrough technology again sets new SCSI I/O standards with the
LSI22910 PCI-to-Ultra2 SCSI dual channel host adapter. Using the LSI53C896
single-chip, PCI-to-Ultra2 SCSI dual controller, the LSI22910 host adapter
offers superior performance, cost savings, enhanced scalability and connec-
tivity advantages.
Matching the maximal performance of the 64-bit PCI bus to two
independent Ultra2 SCSI channels, the LSI22910 host adapter provides up
to 160 MBps aggregate SCSI throughput. Through LSI Logic鈥檚 LVDlink (Low
Voltage Differential) technology, the LSI22910 provides unmatched performance,
device connectivity and signal reliability for Ultra/Ultra2 LVD operation. The
LSI22910 provides a truly universal board able to support single-ended
Fast/Ultra devices, or LVD Ultra/Ultra2 devices. The dual channels offer
increased connectivity without utilizing an additional PCI slot or PCI load.
Designing systems with the LSI22910 is easy because one or both channels
can be dedicated to LVD devices. As an alternative, one channel can be
used to support mixed performance single-ended devices. This board provides
a powerful dual channel, scalable, multitasking interface for SCSI disk
drives, JBOD and RAID system interconnect, and other single-ended or LVD
SCSI devices.
The LSI22910 is a zero wait-state DMA bus master in legacy 32-bit or
64-bit PCI bus systems. The 64-bit host adapter also operates in existing 32-bit
systems, providing greater flexibility with valuable system resources. While
operating in a 32-bit PCI slot, the LSI22910 supports PCI 32-bit Dual
Address Cycles.
The LSI22910 includes an on-board configuration utility, allowing the
viewing and changing of default configuration settings for the host adapter
and SCSI devices. It also provides advanced ease-of-use features such as
automatic termination (depending on cable configuration) and on-board LEDs
for termination power monitoring.
The advanced features of the LSI22910 64-bit PCI to Ultra2 Dual
Channel host adapter make it the right choice for servers of all sizes.
