1.1 General Description
The LSIU160 provides an Ultra160 SCSI interface to PCI computer
systems. It is referred to as the LSIU160 throughout this guide. Installing
this adapter in your PCI system allows connection of up to 15 SCSI
devices.
The LSIU160 is a 16-bit, Low Voltage Differential (LVD)/Single-Ended
(SE) SCSI solution for your computer. This board supports legacy Fast
SCSI and Ultra SCSI devices, and the newest LVD Ultra160 SCSI
devices. It is also backwards compatible with existing wide SCSI
applications for the LSI8251S and LSI8751SP/E host adapters.
The Storage Device Management System (SDMS™) software operates
the board. SCSI software provided by other vendors that works with the
LSI53C1010-33 PCI to Ultra160 Multifunction Controller chip can also be
