Describing the

LSI8751D

This chapter describes how the LSI8751D PCI to SCSI Host Adapter interfaces to PCI computer systems and includes these topics:

•Section 1.1, “General Description,” page 1-1

•Section 1.2, “Features,” page 1-2

1.1General Description

The LSI8751D provides a SCSI-3, Ultra SCSI interface to PCI computer systems. Installing this adapter in your PCI system allows you to connect SCSI devices over a SCSI bus.

The LSI8751D is a 16-bit, High Voltage Differential (HVD), Ultra SCSI solution for your computer, using only one PCI slot. This board can support both legacy Fast SCSI devices and the newest Ultra SCSI devices. It is also backward compatible with the existing LSI8251D host adapter.

The Storage Device Management System (SDMS™) software operates the board, but the design of the board does not prevent other software from being written and used with it.

This guide and the PCI Storage Device Management System SDMS 4.0 User’s Guide contain product information and installation instructions. This information helps you gain the full beneﬁts of the LSI8751D for your computer system.
