1.1 General Description
The LSI21040 provides an Ultra160 SCSI interface to PCI computer
systems. It is referred to as the LSI21040 throughout this guide. Installing
this adapter in your PCI system allows connection of up to 15 SCSI
devices per channel. The LSI21040 uses the LSI53C1010 PCI to
Ultra160 Multifunction Controller chip.
The dual channel LSI21040 provides 16-bit Low Voltage Differential
(LVD) and Single-Ended (SE) SCSI solutions for your computer, using
only one PCI slot. This board supports legacy Fast SCSI, Ultra SCSI,
Ultra2 SCSI, and the newest Ultra160 SCSI devices.
Channel A supports SE and LVD modes of operation. Channel B
supports only the SE mode.
The Storage Device Management System (SDMS™) software operates
the board. You may also use SCSI software provided by other vendors
