1.1 General Description
The LSI Logic LSI20160 provides one SCSI-3, Ultra160 SCSI interface
to PCI computer systems that require BIOS support on the add-in SCSI
adapter. Installing this adapter in your PCI system allows connection of
SCSI devices over a SCSI bus.
The LSI20160 provides one Ultra160 SCSI channel. The LSI20160
supports Low Voltage Differential (LVD) and Single-Ended (SE) SCSI.
This board supports Fast/Ultra/Ultra2 SCSI devices as well as the newest
Ultra160 SCSI devices.
The LSI Logic Storage Device Management System (SDMS?) software
operates the board. The design of the board does not prevent other SCSI
software from being used with it. BIOS support for this host adapter is
incorporated on the board in a 128 Kbyte Flash device. The onboard
controller for the LSI20160 is the LSI53C1000 PCI to Ultra160 SCSI
Controller.
1-2 Describing the LSI20160
Copyright ? 2001 by LSI Logic Corporation. All rights reserved.
The LSI53C1000 contains a SCSI SCRIPTS? processor that permits
both DMA and SCSI commands to be fetched from host memory or
internal SCRIPTS RAM. Algorithms written in SCSI SCRIPTS control the
actions of the SCSI and DMA cores. The SCRIPTS processor executes
complex SCSI bus sequences independently of the host CPU.
In addition to this guide there is another reference that you will find
useful. The LSI Logic PCI Storage Device Management System
SDMS 4.0 User뭩 Guide contains product information and installation
instructions.

1.2.3 Board Characteristics
The board characteristics are
? PCI board dimensions
Approximately 4.721 x 2.536 inches
? Universal 32-bit PCI card edge connector
? Standard bracket available
1.2.4 SCSI Activity LED Interface
The J3 connector is a four-wire arrangement on the LSI20160 that
represents the SCSI activity LED interface. Table 3.5 on page 3-8 lists
the signal name and pin numbers for this LED interface.
1.3 Ultra160 SCSI Benefits
Ultra160 SCSI is an extension of the SPI-3 draft standard that allows
faster synchronous SCSI data transfer rates than Ultra2 SCSI. When
enabled, Ultra160 SCSI performs 80 megatransfers per second resulting
in approximately double the synchronous data transfer rates of Ultra2
SCSI. The LSI53C1000 performs 16-bit, Ultra160 SCSI synchronous
data transfers as fast as 160 Mbytes/s. This advantage is most
noticeable in heavily loaded systems or large block size applications
such as video on-demand and image processing.
1.3.1 Double Transition (DT) Clocking
The Ultra160 data transfer speed is accomplished using DT clocking.
DT clocking refers to transferring data on both rising and falling edges of
the request and acknowledge signals. Double-edge clocking doubles
data transfer speeds without increasing the clock rate.
SureLINK? Ultra160 SCSI Domain Validation Benefits 1-5
Copyright ? 2001 by LSI Logic Corporation. All rights reserved.
1.3.2 Cyclic Redundancy Check (CRC)
Ultra160 SCSI includes CRC which offers higher levels of data reliability
by ensuring complete integrity of transferred data. CRC is a 32-bit
scheme, referred to as CRC-32. CRC is guaranteed to detect all single
bit errors, any two bits in error, or any combination of errors within a
single 32-bit range.
1.3.3 Asynchronous Information Protection (AIP)
The LSI53C1000 also supports AIP, which protects all nondata phases,
including command, status, and messages. CRC, along with AIP,
provides end-to-end protection of the SCSI I/O.
1.4 SureLINK? Ultra160 SCSI Domain Validation Benefits
SureLINK software represents the very latest SCSI interconnect
management solution. It ensures robust and low risk Ultra160 SCSI
implementations by extending the Domain Validation guidelines
documented in the ANSI T10 SPI-3 specifications. Domain Validation
verifies that the system is capable of transferring data at Ultra160
speeds, allowing it to renegotiate to lower speed and bus width if
necessary.
SureLINK software is the control for the manageability enhancements in
the LSI53C1000. Fully integrated in the SDMS software solution,
SureLINK software provides Domain Validation at boot time, as well as
throughout system operation.
1.5 LVDlink? Technology Benefits
The LSI20160 supports LVD for SCSI, a signaling technology that
increases the reliability of SCSI data transfers over longer distances than
are supported by SE SCSI. The low current output of LVD allows the I/O
transceivers to be integrated directly onto the chip. LVDlink technology
lowers the amplitude of noise reflections and allows higher transmission
frequencies. LVD provides a long-term migration path to even faster
SCSI transfer rates without compromising signal integrity, cable length,
or connectivity.
1-6 Describing the LSI20160
Copyright ? 2001 by LSI Logic Corporation. All rights reserved.
Important: All bus devices must be LVD or SE. If a High Voltage
Differential (HVD) device is detected, the board puts the
SCSI bus in the high impedance state and shuts down.
1.6 TolerANT? Technology Benefits
The LSI20160 features TolerANT technology, which includes active
negation on the SCSI drivers and input signal filtering on the SCSI
receivers. The benefits of TolerANT technology include increased
immunity to noise when the signal is going HIGH, better performance
due to balanced duty cycles, and improved fast SCSI transfer rates. In
addition, TolerANT SCSI devices do not cause glitches on the SCSI bus
at power up or power down, so other devices on the bus are also
protected from data corruption.
When it is used with the LVDlink transceivers, TolerANT technology
provides excellent signal quality and data reliability in real world cabling
environments. TolerANT input signal filtering is a built-in feature of the
LSI53C1000 device as well as all LSI Logic SCSI devices.

2.2.4.2 Making Activity LED Connection
Most PC cabinets are designed with a front panel LED to indicate bus
activity. It may already be connected to an existing IDE controller. If you
want, you can connect the LED to the SCSI LED connector.
Connect the LED cable to J3 on your SCSI host adapter, as shown in
Figure 2.8.
The Busy LED connector J3 is not keyed. The J3 connector is a 4-pin
one row right angle header. Some LED cables have only two wires. In
this case, place the connector on one end of J3. If the LED does not light
during SCSI bus activity, you may have to rotate the LED cable 180? on
J3 or move it to the other end of the jack.

2.2.5 SCSI Bus Termination
The devices making up the SCSI bus are connected serially (chained
together) with SCSI cables. The first and last physical SCSI devices
connected on the ends of the SCSI bus must have their terminators
active. All other SCSI devices on the bus must have their terminators
removed or disabled.
Termination control has two options which allow a different termination
mode:
? Termination can be disabled by placing a manual shunt over the
post. When the shunt is off, the terminator is active. When the shunt
is on the post, the terminator is disabled.
? Termination can be enabled or disabled for a specific channel using
software control with GPIO3.
LVD peripheral devices are normally terminated with external
terminators, but are sometimes set with jumpers or with a switch on the
peripheral. Refer to the peripheral manufacturer뭩 instructions and to the
user뭩 manual for your computer for information on how to identify the
terminator setting of each device and how to change it.
The LSI20160 automatically controls SCSI bus termination for two
different bus configurations (see Figure 2.1). The two bus configurations
are
? Termination on
? Termination off
You can disable termination in two ways:
? Use BIOS software control, where the BIOS termination option is
changed from Automatic to Off.
? Manually place a shunt on the post of the respective jumpers, J2DIS
and J4DIS.

2.2.5.1 Internal SCSI Terminations
If you are making internal SCSI device connections on your host adapter,
you must terminate the last internal device on the SCSI bus. You must
disable the termination on all other devices. Termination on your host
adapter is automatically enabled in this case if there are no external
SCSI devices connected through J2.
Figure 2.12 shows an example of how termination is determined for this
SCSI bus configuration.

2.2.6 Setting SCSI IDs
You must set each SCSI device and the host adapter to a separate SCSI
ID. The IDs are 0 through 7 for an 8-bit bus and 0 through 15 for a 16-bit
bus. SCSI ID 7 is the preset host adapter setting, giving it the highest
priority on the SCSI bus. If you plan to boot your computer from a hard
disk drive on the SCSI bus, that drive should have SCSI ID 0, or the
lowest SCSI ID on the bus. The PCI Storage Device Management
System SDMS 4.0 User뭩 Guide explains how to set your host adapter
ID using the SCSI BIOS Configuration Utility.
The peripheral device SCSI IDs are usually set with jumpers or with a
switch on the peripheral. Refer to the peripheral manufacturer뭩
instructions and to the user뭩 manual for your computer to determine the
ID of each device and how to change it. No duplication of SCSI IDs is
allowed on a SCSI bus.
Step 1. Determine the SCSI ID of each device on the SCSI bus. Note
any duplications.
Step 2. Make any necessary changes to the SCSI IDs and record the
IDs for future reference. Correct any duplications at this time.
Table 2.1 on page 2-19 is provided as a place to keep this
record.

3.2 Operational Environment
The LSI20160 is designed for use in PCI computer systems with a
standard bracket type. The SDMS software operates the board, but the
design of the board does not prevent the use of other software. An onboard
Flash memory device allows you to use BIOS code and open boot
code support through PCI and a serial EEPROM.
3.2.1 The PCI Interface
The PCI interface operates as a 32-bit DMA bus master. The connection
is made through edge connector J1, which provides connections on both
the front and back of the board. The signal definitions and pin numbers
conform to the PCI Local Bus Specification, Revision 2.2 standard. The
signal assignments appear in Table 3.2, Table 3.3, and Table 3.4.
Note: The LSI20160 uses 3.3 V pins to run the LSI53C1000 and
some other parts. The LSI20160 requires 3.3 V from the
PCI + 3.3 V power rail for proper operation.

3.2.2 The SCSI Interface
The SCSI interface conforms to ANSI X 3T10.11/1142. The SCSI
interface operates as 16-bit, synchronous or asynchronous, SE or LVD,
and supports Ultra160 SCSI protocols. Arbitration is supported for 8-bit
(at lower SCSI speeds) and 16-bit. Active SE or LVD SCSI termination
is provided automatically. The LSI20160 supplies the SCSI termination
power.
Connector J2 makes the external connection, which provides LVD/SE
SCSI termination. Connector J4 makes the internal connection, which
only provides LVD SCSI termination.

20 Mbytes/s over an 8-bit SCSI bus and up to 40 Mbytes/s over a 16-bit
SCSI bus. SCSI Trade Association (STA) supports using the term 밬ltra
SCSI? over the older term 밊ast-20?.
Ultra2 SCSI A standard for SCSI data transfers. It allows a transfer rate of up to
40 Mbytes/s over an 8-bit SCSI bus, and up to 80 Mbytes/s over a
16-bit SCSI bus. SCSI Trade Association (STA) supports using the term
밬ltra2 SCSI? over the term 밊ast-40?.
