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.

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.
44.25 pc
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.
