LSI20160 Single Channel Ultra160 SCSI to PCI Host Adapterv
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 devicesas 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.
LSI20160 Single Channel Ultra160 SCSI to PCI Host Adapter1-1
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 SystemSDMS 4.0 User’s Guide contains product information and installation
instructions.
1.2Features
This section provides an overview of the PCI interface, the SCSI
interface, and board characteristics for the LSI20160.
1.2.1 PCI Interface
The PCI interface operates as a 32-bit DMA bus master, where the
connection is made through the J1 edge connector.
The PCI interface includes these features:
•Complies with PCI Local Bus Specification, Revision 2.2
•Complies with PC99
•Complies with PCI Bus Power Management Specification,
Revision 1.1
•Supports 32-bit 33 MHz word data bursts with variable burst lengths
•Bursts 4/8, 8/16, 16/32, or 32/64 Qword/Dword transfers across the
PCI bus
•Bursts up to 264 Mbytes/s (@ 33 MHz) with zero wait-state bus
master data
•Supports the PCI Cache Line Size (CLS) register
•Prefetches up to 8 Dwords of SCRIPTS instructions
•Supports PCI Write and Invalidate, Read Line, and Read Multiple
commands
•Supports universal 3.3 V and 5 V PCI bus signaling environment
The SCSI interface is made through connectors J2 and J4. Figure 2.1
shows the location of these connectors. The SCSI interface includes
these features:
•Provides one wide Ultra160 SCSI channel
•Provides two connectors:
–68-pin VHDCI for the external connection
–68-pin high density for the internal connection
•Supports SE and LVD signaling: 16-bit SE or LVD interfaces
•Supports LVD/SE termination
•Supports Fast, Ultra, Ultra2, and Ultra160 data transfer capability
–Ultra160 SCSI LVD synchronous transfers at up to 160 Mbytes/s
•Supports Domain Validation, Double Transition (DT) data transfers,
and Cyclic Redundancy Check (CRC)
•Supports variable block size and scatter/gather data transfers
•Protects nondata phases with Asynchronous Information Protection
(AIP)
•Supports two termination control options:
–Use manual shunts on connector J2 and J4 to disable
termination
–Provide software control using GPIO3 to enable or disable the
terminators
•Supplies SCSI termination power (TERMPWR) source with
autoresetting circuit breaker
•Includes SCSI Plug and Play
•Provides Flash EEPROM for BIOS configuration storage
•Includes 8 Kbytes internal RAM for SCRIPTS instruction storage
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.
1.3Ultra160 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.
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.
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.
1.5LVDlink™ 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.
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.
1.6TolerANT®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.
