pc1.1 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
