Chapter 1 Describing the LSI22915A

This chapter describes the features, interfaces, and characteristics of the LSI22915A PCI to Dual Channel Ultra160 SCSI Host Adapter. The chapter includes the following sections:

• Section 1.1, “Introduction,”

• Section 1.2, “Features”

• Section 1.3, “SureLINK™ Ultra160 SCSI Domain Validation Beneﬁts”

• Section 1.4, “LVDlink™ Technology Beneﬁts”

• Section 1.5, “TolerANT® Technology Beneﬁts”

1.1 Introduction

The LSI22915A has two 16-bit Low Voltage Differential (LVD) and Single-Ended (SE) Ultra160 SCSI channels that connect to the PCI local bus on your computer. The LSI22915A is tailored to systems that require on-board BIOS support. When you install the LSI22915A in your PCI system, you can connect up to 15 SCSI disk drives and other SCSI devices to each of its two SCSI channels. In addition to Ultra160 SCSI devices, the LSI22915A also supports legacy Fast, Ultra, and Ultra2 SCSI devices.

The LSI22915A controls the SCSI devices that are connected to it. The chain of internal and external SCSI devices connected to each SCSI channel is referred to as a SCSI bus.

Storage Device Management System (SDMS™) software operates the board. However, the design of the board allows you to use other SCSI software. BIOS support for this host adapter is incorporated on the board in a 128 Kbyte Flash EEPROM.

1.2 Features

This section provides a high-level overview of the PCI interface, the SCSI interfaces, and other board characteristics of the LSI22915A.

1.2.1 PCI Interface

The PCI interface connection is made through edge connector J6, which is shown in Figure 2.1 on page 2-2. The PCI interface includes these features:

• Full 64-bit (66 MHz) DMA bus master

• Zero wait-state bus master data bursts

• PCI Universal 3.3 V/5 V bus support

• Compliance with PC 99 Speciﬁcation

• Compliance with PCI Local Bus Speciﬁcation, Revision 2.2

1.2.2 SCSI Interfaces

4.0 User’s Guide, contains product information and installation

The LSI22915A has two 16-bit, synchronous or asynchronous, SE or LVD interfaces. They support Ultra160 SCSI protocols and 16-bit arbitration. The interface is made through connectors J1 and J3 for Channel A, and J7 and J4 for Channel B. The SCSI interface includes these features:

• Two separate SCSI channels

• 16-bit SE/LVD

• Automatically enabled termination

• Fast, Ultra, Ultra2, and Ultra160 data transfer capability

• SCSI termination power (TERMPWR) source with autoresetting

circuit breaker and TERMPWR shorted LED for each channel

• SCSI Plug and Play

• SCSI Conﬁgured AutoMatically (SCAM)

• Flash EEPROM for BIOS storage

1-2 Describing the LSI22915A

• Serial nonvolatile random access memory (NVRAM) on each

channel for user conﬁguration utility and SCAM information storage

• SCSI activity LED for each channel

1.2.3 Board Characteristics

The board characteristics of the LSI22915A are:

• PCI board dimensions of 4.2 by 8.4 inches (106.68 by 213.36 mm)

• Universal 64-bit PCI card edge connector

• Two 68-pin Very High Density Cable Interconnect (VHDCI)

connectors, one for each external channel

• Two68-pin high density (HD) connectors, one for each internal channel

• ISA/EISA bracket

1.2.4 LED Interface

The LSI22915A LED interface is a four-wire arrangement that allows you to connect an LED harness to the board. The connector on the LSI22915A is HDR2 for both channels. Table 3.2 on page 3-4 lists the signal names and pin numbers for this LED interface.

The LSI22915A has four individual LEDs per channel to indicate the operating state of the board.

1.2.5 Ultra160 SCSI Beneﬁts

Ultra160 SCSI is an extension of the SCSI Parallel Interface-3 (SPI-3) draft standard that allows faster synchronous SCSI data transfer rates than Ultra2 SCSI. When enabled, Ultra160 SCSI performs 80 megatransfers/s, resulting in approximately double the synchronous data transfer rates of Ultra2 SCSI. The LSI53C1010 performs 16-bit, Ultra160 SCSI synchronous data transfers as fast as 160 Mbytes/s.

The faster data transfer rate is most noticeable in heavily loaded systems or large block size applications such as video on demand and image processing.

Important. To achieve Ultra160 SCSI performance, you must connect

only LVD devices to the bus. If you mix any SE devices with LVD devices, the entire bus drops to SE, limiting bus performance to Ultra SCSI levels.
