1.3 Benefits of Ultra160 SCSI

Ultra160 SCSI delivers data up to two times faster than Ultra2 SCSI.
Ultra160 SCSI is a subset of the SCSI Parallel Interface-3 (SPI-3) draft
standard that allows faster synchronous SCSI data transf er 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 LSI53C1010 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

Ultra160 SCSI includes DT clocking in order to double data transfer
speeds without increasing the clock rate. As a result, data is clocked on
both rising and falling edges of the Request and Acknowledge signals.

44.25 pc

1.3.2 Cyclic Redundancy Check (CRC)

Ultra160 SCSI includes CRC to provide data bus protection. CRC 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, all double bit errors, or any
combination of errors within a single 32-bit range.

1.3.3 Domain Validation

Ultra160 SCSI also includes Domain Validation to provide basic integrity
checking. Domain Validation is a procedure that allows a host computer
and target SCSI peripheral to negotiate and find the optimal transfer
speed. This procedure improves overall reliability of the system.
SURElink™ extends this feature by providing three levels of integrity
checking. Refer to Section 1.6, “Benefits of SURElink (Extended Domain

Validation),” on page 1-7 for more detailed information.

1.3.4 Asynchronous Information Protection (AIP)

4.333 pc

The LSI53C1010 supports AIP to protect all non-data phases, including
command, status, and messages. CRC, along with AIP, provides end-to­end protection of the SCSI I/O.

1.4 Benefits of LVD Link Technology

To support greater device connectivity and a longer SCSI cable, the
LSI21040 features LVD Link technology, the LSI Logic implementation of
Universal LVD SCSI. LVD Link transceivers provide the inherent reliability
of differential SCSI, and a long-term migration path to faster SCSI
transfer rates.

The LVD Link transceivers reduce the power needed to drive the SCSI
bus, so that the I/O drivers can be integrated directly into the chip.
LVD Link technology lowers the amplitude of noise reflections and allows
higher transmission frequencies.

44.25 pc

The LVD Link transceivers operate in LVD and SE modes. They also
allow the chip to detect a High Voltage Differential (HVD) signal when the
chip is mistakenly connected to external HVD transceivers. When
connected, the LSI53C1010 automatically detects signal type, based on
the voltage detected. It automatically switches to the SE or LVD mode,
as appropriate.

Important:

All bus devices must be LVD or SE. If a HVD device is
detected, the board puts the SCSI bus in the high
impedance state and shuts down.

1.5 Benefits of TolerANT®Technology

The LSI53C1010 features TolerANT technology, which includes active
negation on the SCSI drivers and input signal filtering on the SCSI
receivers. Active negation causes the SCSI Request, Acknowledge,
Data, and Parity signals to be actively driven HIGH rather than passively
pulled up by terminators.

52.5 pc

3.75 pc 10.25 pc 11.25 pc 38.25 pc

34.5 pc

TolerANT receiver technology improves data integrity in unreliable

4.333 pc

cabling environments where other devices would be subject to data
corruption. TolerANT receivers filter the SCSI bus signals to eliminate
unwanted transitions, without the long signal delay associated with
RC-type input filters. This improved driver and receiver technology helps
eliminate double clocking of data, which is the single biggest reliability
issue with SCSI operations. TolerANT input signal filtering is a built-in
feature of the LSI53C1010 and all LSI Logic Fast SCSI, Ultra SCSI,
Ultra2 SCSI, and Ultra160 SCSI devices.

The benefits of TolerANT technology include increased noise immunity
when the signal transitions to HIGH, better performance due to balanced
duty cycles, and improved fast SCSI transfer rates. In addition, TolerANT
SCSIdevicesdonotcauseglitchesontheSCSIbusatpower-upor
power-down. This technology protects other devices on the bus from data
corruption. When it is used with the LVD Link transceivers, TolerANT
technology provides excellent signal quality and data reliability in real
world cabling environments. TolerANT technologyis compatible with both
the Alternative One and Alternative Two termination schemes proposed
by the American National Standards Institute.

1.6 Benefits of SURElink (Extended Domain Validation)

SURElink 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 is the software control for the manageability enhancements in
the LSI53C1010. Fully integrated in the SDMS software solution,
SURElink provides Domain Validation at boot time as well as throughout
system operation. SURElink extends to the Distributed Management
Interface (DMI) based System Management components of SDMS,
providing the network administrator remote management capability.

SURElink Domain Validation provides three levels of integrity checking:
Basic (lev el 1), Enhanced (level 2), and Margined (level 3). The basic
check consists of an inquiry command to detect gross problems. The

Benefits of SURElink (Extended Domain Validation) 1-7

52.5 pc

3.75 pc 10.25 pc 11.25 pc 38.25 pc

34.5 pc

enhanced check sends a known data pattern using the Read and Write

4.333 pc

Buffer commands to detect additional problems. The margined check
verifies that the physical parameters have some degree of margin.

By varying LVD drive strength and REQ/ACK timing characteristics,
level 3 verifies that no errors occur on the transfers. These altered
signals are only used during the diagnostic check and not during normal
system operation. Should errors occur with a ny of these checks, the
system can drop back to a lower transmission speed, on a per-target
basis, to ensure robust system operation.

2.2.1 Before You Start

Before starting, look through the following task list to get an overall idea
of the steps you will be performing. If you are not confident you can
perform the tasks as described here, LSI Logic recommends getting
assistance.

The SCSI host adapter acts on your computer’s behalf as the host to
your suite of SCSI peripherals. Each chain of SCSI peripheral devices
and their host adapter work together. They are referred to as a SCSI bus.

Each SCSI host adapter that you install can act as host for up to
15 peripheral devices, not including the adapter itself. Follow the detailed
instructions in the next section to successfully install your host adapter
board.

2.2.2 Inserting the Host Adapter

For safe and proper installation, you will need the user’s manual supplied
with your computer. Perform the following steps to install the LSI21040.

Caution:

Ground yourself by touching a metal surface before
removing the cabinet top . Static charges on your body can
damage electronic components. Handle plug-in boards by
the edge; do not touch board components or gold
connector contacts. The use of a static ground strap is
recommended.

Step 5. Locate the slots for PCI plug-in board installation.

Refer to the user’s manual for your computer to confirm the

location of the PCI slots.

The LSI21040 requires a 32-bit or 64-bit PCI slot that allows

bus master operation. If a 32-bit PCI slot is used, bits [31:0] of

the J1 connector are inserted while bits [63:32] remain

uninserted. See Figure 2.2.

Note:

For the LSI21040 to function as a 64-bit device, it must be
inserted in a 64-bit PCI slot. If the LSI21040 is inserted in
a 32-bit PCI slot, it will function as a 32-bit device.

Step 6. Remove the blank bracket panel on the back of the computer

aligned with the PCI slot you intend to use. Save the bracket

screw.

2.2.3 Connecting the SCSI Peripherals

4.333 pc

All internal SCSI bus connections to the LSI21040 are made with an
unshielded 68 conductor Ultra SCSI TPE ribbon cable (see Figure 2.3)
and also a 50-pin ribbon cable. The lead connected to pin 1 on the cable
is marked with a colored stripe. The connectors on this cable may also
be keyed to ensure proper pin connection.

All external SCSI bus connections to the LSI21040 are made with high
quality shielded 68 conductor cables (see Figure 2.3). The connectors on
this cable are always keyed to ensure proper pin connection.

44.25 pc

Note:

All the cables shown in Figure 2.3 are included in the
LSI Logic Adapter Board Kit for the LSI21040.

2.2.6 SCSI Bus Termination

4.333 pc

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. Remember that the LSI21040 is also on the SCSI
bus—its termination is automatically enabled when it is connected to the
end of the bus.

44.25 pc

Important:

To utilize Ultra2 and faster SCSI performance, you must
only have LVD devices on the bus. Do not mix any SE
devices with L VD devices or the entire bus will drop to SE,
limiting bus performance to Ultra SCSI levels.

The peripheral device terminators are usually set with jumpers, resistor
modules, or with a switch on the peripheral. Refer to the peripheral
manufacturer’s instructions and to the user’s manual f or your computer
for information on how to identify the terminator type/setting for each
device and how to set/change it.

Caution:

The autoenable/disable sensing feature on the LSI21040
may enable termination erroneously if it is directly cabled to
another SCSI device or host adapter using the same
sensing method. The LSI21040 senses the presence of
SCSI devices by detecting the ground signal on
conductor 50 of the 68-pin SCSI cable and conductor 22 on
the 50-pin SCSI cable.

The LSI21040 automatically controls SCSI bus termination for three
different bus configurations, depending on how it is connected (see

Figure 2.1). The three bus configurations are:

• Section 2.2.6.1, “Internal Bus Connections”

• Section 2.2.6.2, “External Bus Connections”

• Section 2.2.6.3, “Internal and External Bus Connections”

Termination on the LSI21040 for these three different bus configurations
is discussed below.

2.2.7 Setting SCSI IDs

You must set each SCSI device and the host adapter to a separate SCSI
ID 0 through 15. 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 SCSI hard disk driv e on the SCSI bus, that drive should have the
lowest SCSI ID on the bus. Typically, SCSI ID 0 is used; however, for
system performance optimization, an ID other than 0 (zero) can be used.
Refer to Chapter 2 “SCSI BIOS” of the PCI Storage Device Management
System SDMS 4.0 User’s Guide about how to set the host adapter ID
using the LSI Logic 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 manufacturer’s
instructions and to the user’s manual for your computer to determine the
ID of each device and how to change it.

• Cabling – Use an unshielded 68 conductor Ultra SCSI TPE ribbon

cable and a 50-pin ribbon cable for internal connections. Ensure the
pin-1 orientation is correct for internal cables. Use a 68-pin high
density SCSI cable for external connections.

• SCSI Devices –SeteachSCSIdeviceandthehostadaptertoa

separate SCSI ID 0 through 15. You must not have any duplication
of SCSI IDs on a SCSI bus. The default SCSI ID for the host adapter
is SCSI ID 7.

• Termination – Automatic termination is enabled when the LSI21040

is connected to the end of the bus. For internal and/or external bus
connections, terminate the last internal and/or external device on the
SCSI bus.

Physical Environment 3-3

3.2 Operational Environment

Use the LSI21040 in PCI computer systems with an ISA/EISA bracket
type. The SDMS operates the board, but the design of the board does
not prevent the use of other software. An on-board flash memory device
is provided to allow BIOS code and open boot code support through PCI
and a serial EEPROM for each channel.

3.2.1 The PCI Interface

The PCI interface operates as a 64-bit DMA bus master. Edge connector
J1 makes the PCI connection, 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.

Table 3.1 and Table 3.2 show the signal assignments. The on-board

+3.3 V regulator provides power to the PCI portion of the LSI53C1010
device.

Note:

The +3.3 V pins are tied together and decoupled with high
frequency bypass capacitors to ground. No current from
these +3.3 V pins is used on the board. The board derives
power from the +5 V pins, directly and through a 3.3 V
voltage regulator. The PCI +3 V/+5 V pins are used to
differentiate between a 5 V or a 3.3 V PCI environment.

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. SCSI termination power is supplied by the
board.

Connectors J3 and J4 for Channel A and J2 and J5 for Channel B make
the SCSI interface. Refer to Figure 2.1 on page 2-4 toseeanexample
of this interface. J2 and J4 are 68-pin high density right angle connectors
for internal SCSI connections. J5 is a 50-pin low density vertical
connector. External connector J3 is a shielded 68-pin high density right
angle connector exposed in the back panel bracket.

LVD/SE dual mode, active termination is provided on the LSI21040 for
Channel A. SE SCSI termination is provided for Channel B. The
LSI21040 supplies SCSI bus TERMPWR through a blocking diode and
a self-resetting 1.5 A short circuit protection device. A 40 MHz oscillator
is installed on the LSI21040. This oscillator provides the clock frequency
necessary to support Ultra160 SCSI transfers of up to 160 Mbytes/s.

Table 3.3 and Table 3.4 show the signal assignments for J2 and J5.
Table 3.5 and Table 3.6 show the signal assignments for J4 and J3.
