Adapter board interface to PCI computer systems and includes these  
topics:  
Section 1.1, “General Description,page 1-1  
Section 1.2, “Features,page 1-2  
Section 1.3, “Interface Descriptions,page 1-3  
1.1 General Description  
The LSIU80ALVD provides an Ultra2 SCSI interface to PCI computer  
systems. It will be referred to as the LSIU80ALVD throughout this  
manual. Installing this adapter in your PCI system allows connection of  
up to 15 SCSI devices.  
The LSIU80ALVD is a 16-bit, Low Voltage Differential (LVD)/Single-  
Ended (SE) SCSI solution for your computer. This board can support  
legacy Fast SCSI and Ultra SCSI devices, and the newest LVD Ultra2  
SCSI devices. It is also backwards compatible with existing wide SCSI  
applications for the LSI8251S and LSI8751SP/E host adapters.  
The Storage Device Management System (SDMS™) software operates  
the board. Other SCSI software that works with the LSI53C895A PCI to  
Ultra2 Controller with LVDlink™ Universal Transceivers chip could also  
be used. BIOS support for this adapter is incorporated on the board in a  
Flash memory device. The LSIU80ALVD has a serial EEPROM device  
for storing the user’s SCSI bus configuration.  
This guide, along with the PCI Storage Device Management System  
SDMS 4.0 User’s Guide, contains product information and installation

1.3 Interface Descriptions  
This section provides a more detailed explanation about the PCI  
Interface, the SCSI Interface, Ultra2 SCSI Technology, and LVDlink  
Technology.  
1.3.1 The PCI Interface  
PCI is a high-speed standard local bus for interfacing a number of I/O  
components to the processor and memory subsystems in equipment  
ranging from PCs to servers. The PCI functionality for the LSIU80ALVD  
is contained within the LSI53C895A. The LSI53C895A connects directly  
to the PCI bus and generates signal timing and bus protocol in  
compliance with the PCI Specification Revision 2.1.  
The PCI interface operates as a 32-bit DMA bus master. The connection  
is made through edge connector J1 (see Figure 2.1). The signal  
definitions and pin numbers conform to the PCI Local Bus Specification  
Revision 2.1 standard. The LSIU80ALVD conforms to the PCI universal  
signaling environment for a 5 V or 3.3 V PCI bus.  
Interface Descriptions  
1-3  
 
         
1.3.2 The SCSI Interface  
The SCSI functionality for the LSIU80ALVD is contained within the  
LSI53C895A. The LSI53C895A connects directly to the SCSI bus and  
generates signal timing and bus protocol in compliance with the SCSI  
standard.  
The SCSI interface on the LSIU80ALVD operates as an 8-bit or 16-bit  
interface. It supports 8-bit or 16-bit, synchronous and asynchronous, LVD  
or SE, Fast, Ultra and Ultra2 SCSI protocols in various combinations.  
The interface is made through connectors J2 and J3 (see Figure 2.1).  
Internal connector J2 is a 68-pin HD right angle latching connector.  
External connector J3 is a shielded 68-pin HD right angle connector that  
protrudes through the back panel bracket.  
An on-board LED (labeled Activity) indicates SCSI bus activity.  
LVD/SE dual mode, active termination is provided on the LSIU80ALVD.  
Termination is automatically disabled when both SCSI connectors are  
used.  
The LSIU80ALVD 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 LSIU80ALVD to provide the clock  
frequency to the LSI53C895A that is necessary to support Ultra2 SCSI  
transfers of up to 80 Mbytes/s.  
1-4  
Using the LSIU80ALVD  
 
   
1.3.3 Ultra2 SCSI Technology  
The LSIU80ALVD fully supports Ultra2 SCSI. Ultra2 SCSI is an extension  
of the SCSI Parallel Interface 2 and 3 (SPI-2 and SPI-3) family of  
standards that expands the bandwidth of the SCSI bus, allowing faster  
synchronous data transfers.  
For the internal bus, special impedance SCSI ribbon cables are specified  
for operation with Ultra and Ultra2 SCSI devices. You must consider the  
total length of the bus cables and the number of devices on the SCSI  
bus when setting up your system.  
Use SCSI cables that have been rated for standard SCSI (Fast, Ultra,  
and Ultra2) environments.  
See Chapter 2, “Installing the LSIU80ALVD,” for a detailed explanation of  
SCSI bus connections.  
1.3.4 LVDlink Technology  
To support greater device connectivity and a longer SCSI cable, the  
LSIU80ALVD features LVDlink technology, the LSI Logic implementation  
of Universal LVD SCSI. LVDlink transceivers provide the inherent  
reliability of differential SCSI, and a long-term migration path to faster  
SCSI transfer rates.  
The LVDlink transceivers reduce the power needed to drive the SCSI  
bus, so that the I/O drivers can be integrated directly into the chip.  
LVDlink technology lowers the amplitude of noise reflections and allows  
higher transmission frequencies.  
The LVDlink 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. The LSI53C895A  
automatically detects which type of signal is connected, based on the  
voltage detected, and automatically switches as needed to the SE or LVD  
mode. 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.  
Interface Descriptions  
1-5  
 
         
1.3.4.1  
Benefits of LVDlink  
The LSI53C895A supports LVD for SCSI, which is a signaling technology  
that increases the reliability of SCSI data transfers over longer distances  
than supported by SE SCSI. The low current output of LVD allows the  
I/O transceivers to be integrated directly into the chip. LVD provides the  
reliability of HVD SCSI without the added cost of external differential  
transceivers. Ultra2 SCSI with LVD allows a longer SCSI cable and more  
devices on the bus, using the same cables defined in the SCSI-3 parallel  
Interface (SPI-2) standard for Ultra SCSI.  
Important: To utilize Ultra2 SCSI performance, the user must only  
have LVD devices on the bus. Do not mix any SE devices  
with LVD devices as the entire bus will drop to SE with  
maximum Ultra SCSI performance.  
1.3.5 On-Board LED  
On-board LEDs are used to indicate the status of the SCSI bus.  
The SCSI Activity LED lights when the SCSI bus is transferring  
information.

Chapter 2  
Installing the  
LSIU80ALVD  
This chapter provides instructions on how to install the LSIU80ALVD and  
includes these topics:  
Section 2.1, “Quick Installation Procedure,page 2-1  
Section 2.2, “Detailed Installation Procedure,page 2-3  
Section 2.3, “Completing the Installation,page 2-24  
2.1 Quick Installation Procedure  
This section is provided for the experienced computer user with prior host  
adapter installation and SCSI bus setup experience. If you prefer a more  
detailed guidance for installing the LSIU80ALVD, follow the instructions  
in the Section 2.2, “Detailed Installation Procedure.”  
For safe and proper installation, check the user’s manual supplied with  
your computer and perform the following steps.  
Step 1. Ground yourself before removing this host adapter board.  
Remove the LSIU80ALVD from the packing and check that it is  
not damaged. An example of this host adapter board is shown  
in Figure 2.1.  
Step 2. Switch off and unplug the system.  
Step 3. Remove the cabinet cover on your computer to access the PCI  
slots.  
Caution:  
Ground yourself by touching a metal surface before  
handling boards. 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.  
LSIU80ALVD PCI to Ultra2 SCSI Host Adapter  
2-1  
 
     
Step 4. Locate the slots for installing a PCI plug-in board. The  
LSIU80ALVD requires a PCI slot that allows bus master  
operation. See Table 2.2.  
Step 5. Remove the blank bracket panel on the back of the computer  
aligned with the PCI slot you intend to use. Save the bracket  
screw.  
Step 6. Carefully insert the edge connector J1 of the host adapter into  
the PCI slot. Make sure the edge connector is properly aligned  
before pressing the board into place. See Figure 2.2.  
Note:  
You may notice that the components on a PCI host adapter  
face the opposite way from non-PCI adapter boards you  
have in your system. This is correct, and the board is keyed  
to go in only one way.  
Step 7. The bracket around connector J3 (see Figure 2.1) should fit  
where the blank bracket panel was removed. Secure the  
bracket with the bracket screw before making the internal and  
external SCSI bus connections.  
Step 8. If you are connecting any internal SCSI devices, plug a 68-pin  
connector on the end of the internal SCSI ribbon cable into  
connector J2 (see Figure 2.1). Make certain to match pin 1 on  
both connectors.  
Step 9. Connect the LED cable if desired. This is designed to drive an  
off-board system LED and indicates activity on the SCSI bus.  
The off-board LED will operate at the same time as the  
on-board SCSI Activity LED.  
Step 10. Replace the cabinet cover as described in the user’s manual for  
your computer.  
Step 11. Make all external SCSI bus connections. Finally, refer to the  
PCI Storage Device Management System SDMS 4.0 User’s  
Guide (or the guide for the software you will use) to load the  
driver software for your particular operating system.  
Remember: The SCSI bus requires proper termination, and no duplicate  
SCSI IDs.

2.2.3 Connecting the SCSI Peripherals  
SCSI bus connections to the LSIU80ALVD inside your computer can be  
made with an unshielded 68-conductor Ultra SCSI PVC ribbon cable  
(see Figure 2.3). One side of this cable is marked with a colored stripe  
to indicate pin 1. Sometimes the connectors on this cable are keyed to  
ensure proper pin-1 connection.  
All external SCSI bus connections to the LSIU80ALVD 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-1  
connection.  
Note:  
All the cables shown in Figure 2.3 are included in the  
LSI Logic Adapter Board Kit for the LSIU80ALVD.

Step 3. To plug in additional internal SCSI devices, use an internal  
SCSI ribbon cable with the required number of 68-pin  
connectors attached along its length as shown in Figure 2.6.  
An example of this type of chained connection is shown in  
Figure 2.7. Make sure to match pin 1 on all connections.

Most PC cabinets are designed with a front panel LED. You may connect  
the LED cable to connector J4 on the host adapter, as shown in  
Figure 2.8. This causes the front panel LED to light when there is activity  
on the SCSI bus.  
Connector J4 is not keyed. The orientation of the LED cable does not  
matter as long as all four pins are connected.

Some LED cables have only two wires. In this case, place the connector  
on one end or the other of J4. If the LED does not light during SCSI bus  
activity from this host adapter, you may have to rotate the LED cable  
connector 180° on J4.

2.2.5 Making External SCSI Bus Connections  
This section provides step-by-step instructions about making external  
SCSI bus connections.  
Step 1. To connect external SCSI devices to the LSIU80ALVD, plug the  
68-pin HD connector on one end of a shielded external SCSI  
cable (see Figure 2.3) into the host adapter connector J3 (see  
Figure 2.1).  
This connector is in the bracket attached to the back panel of  
your computer. Figure 2.9 shows how this connection is made.

HD Connector  
Detailed Installation Procedure  
2-15  
 
     
Step 2. Plug the 68-pin connector on the other end of the shielded  
external SCSI cable into the SCSI connector on your external  
SCSI device. An example of this connection is shown in  
Figure 2.10.

Installing the LSIU80ALVD  
 
   
Step 3. To connect more than one external SCSI device to the host  
adapter, you must chain them together with shielded external  
SCSI cables. An example of these chained connections is  
shown in Figure 2.11.

2.2.6 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. Remember that the LSIU80ALVD is also on the  
SCSI bus—its termination is automatically enabled when it is connected  
to the end of the bus.  
Important: To utilize Ultra2 SCSI performance, the user must only have  
LVD devices on the bus. Do not mix any SE devices with  
LVD devices as the entire bus will drop to SE with  
maximum Ultra SCSI performance.  
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 for your computer  
for information on how to identify the terminator setting of each device  
and how to change it.  
Caution:  
The autoenable/disable sensing feature on the  
LSIU80ALVD may enable termination erroneously if it is  
directly cabled to another SCSI device or host adapter  
using the same sensing method. The LSIU80ALVD senses  
the presence of SCSI devices by detecting the ground  
signal on conductor 50 of the SCSI cable.  
The LSIU80ALVD automatically controls SCSI bus termination for three  
different bus configurations, depending on the use of connectors (see  
Figure 2.1). The three bus configurations are:  
Only for internal SCSI connections,  
Only for an external SCSI connection, and  
Connections to both internal and external SCSI connectors.  
Termination on the LSIU80ALVD for these three different bus  
configurations is discussed below.  
2-18

2.2.7  
Internal Bus Connections  
If you have only internal SCSI device connections to your host adapter,  
you must terminate the last internal device on the SCSI bus. You must  
disable the terminators on all other devices. Termination on your host  
adapter is automatically enabled in this case.  
Figure 2.12 shows an example of how termination is determined for this  
SCSI bus configuration.

2.2.8 External Bus Connections  
If you have only external SCSI device connections to your host adapter,  
you must terminate the last external device on the SCSI bus. You must  
disable the terminators on all other devices. Termination on the host  
adapter is automatically enabled in this case.  
Figure 2.13 shows an example of how termination is determined for this  
SCSI bus configuration.

2.2.9 Internal and External Bus Connections  
If internal and external SCSI device connections to your host adapter  
have been made, then terminate the last internal and last external  
devices on the SCSI bus. You must disable the termination on all other  
devices. Termination on the host adapter is automatically disabled in this  
case.  
Figure 2.14 shows an example of how termination is determined for this  
SCSI bus configuration.

2.2.10 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 drive 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.  
Chapter 3, “Configuring the LSIU80ALVD,” explains 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. You must have no duplication of  
SCSI IDs 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 to eliminate  
duplicates and record the IDs for future reference. Table 2.3 is  
provided as a place to keep this record.

3.1 When to Configure the LSIU80ALVD  
In most cases you should not need to change the default configuration  
of the host adapter. You may decide to alter these default values if there  
is a conflict between device settings, or if you need to optimize system  
performance.  
Table 3.1 and Table 3.2 list the configuration settings you can change.  
The global settings affect the host adapter and all SCSI devices that are  
connected to it. The device settings affect only individual SCSI devices.

3.2 Starting the SCSI BIOS Configuration Utility  
If you have LSI Logic SCSI BIOS Version 4.XX, and it includes the  
LSI Logic SCSI BIOS Configuration Utility, you can change the default  
configuration of the SCSI host adapters. You may decide to alter these  
default values if there is a conflict between device settings or if you need  
to optimize system performance.  
You can see the version number of your LSI Logic SCSI BIOS in a  
banner displayed on your computer monitor during boot. If the utility is  
available, the following message also appears on your monitor:  
Press Ctrl-C to start LSI Logic Configuration Utility...  
This message remains on your screen for about five seconds, giving you  
time to start the utility. If you decide to press “Ctrl-C,the message  
changes to:  
Please wait, invoking LSI Logic Configuration Utility...  
After a brief pause, your computer monitor displays the Main Menu of the  
LSI Logic SCSI BIOS Configuration Utility.

Configuring the LSIU80ALVD  
 
           
NonVolatile Random Access Memory (NVRAM) is available on the  
LSIU80ALVD. Changes can be made and stored using this menu driven  
utility.  
Important: This utility is a powerful tool. If, while using it, you somehow  
disable all of your controllers, pressing Ctrl-A (or Ctrl-E on  
version 4.04 or later) after memory initialization during  
reboot allows you to re-enable and reconfigure.  
Note:  
Not all devices detected by the Configuration Utility can be  
controlled by the BIOS. Devices such as tape drives and  
scanners require that a device driver specific to that  
peripheral be loaded. This device driver is provided by the  
device manufacturer.  
3.2.1 Configuration Utility Main Menu  
When you start the LSI Logic SCSI BIOS Configuration Utility, the Main  
Menu appears. This menu displays a list of up to four LSI Logic PCI to  
SCSI host adapters and information about each of them. To select an  
adapter, use only the arrow keys and enter key. Then, you can view  
and/or change the current settings for that adapter and the SCSI devices  
attached to it.  
You can select an adapter only if Current Status is “On”. Changes are  
possible since NVRAM is present on this host adapter.

The settings in this menu are global settings that affect the selected host  
adapter and all SCSI devices attached to it.  
SCAM Support – The LSI Logic BIOS Version 4.0 and above supports  
the SCSI Plug and Play protocol called SCAM. SCAM support by default  
is off in versions 4.09.00 and later for the LSI53C895A device. You may  
choose to turn this on. Note that if this BIOS is flashed onto a board with  
existing settings, then these settings will not be changed to reflect the  
new BIOS defaults. Go into the Configuration Utility to change settings.  
Parity – The LSI Logic PCI to SCSI host adapters always generate  
parity, but some older SCSI devices do not. Therefore, you are offered  
the option of disabling parity checking.  
Note:  
When disabling parity checking, it is also necessary to  
disable disconnects for all devices, as parity checking for  
the reselection phase is not disabled. If a device does not  
generate parity, and it disconnects, the I/O never completes  
because the reselection never completes.

Configuring the LSIU80ALVD  
 
           
Host SCSI ID – This option refers to the host adapter’s SCSI ID, which  
is a unique number used to identify the device on the SCSI bus.  
Note:  
In general, it is suggested that you do not change your host  
adapter ID from the default value of 7, as this gives it the  
highest priority on the SCSI bus.  
Scan Order – This option allows the user to tell the SCSI BIOS and  
device drivers to scan the SCSI bus from low to high (0 to max) SCSI  
ID, or from high to low (max to 0) SCSI ID. If you have more than one  
device on the SCSI bus, changing the scan order changes the order in  
which drive letters are assigned by the system. Drive order may be  
reassigned differently in systems supporting the BIOS Boot Specification  
(BBS).  
See the PCI Storage Device Management System SDMS 4.0 User’s  
Guide, Chapter 2 “SCSI BIOS” for additional information regarding BBS.  
Note:  
The scan order option may conflict with operating systems  
that automatically assign a drive order.  
Removable Media Support – This option defines the removable media  
support for a specific drive. When this option is selected, a window  
appears with three choices:  
None  
Boot Drive Only  
With Media Installed  
None indicates there is no removable media support whether the  
drive is selected in BBS as being first, or first in scan order in  
non-BBS.  
Boot Drive Only provides removable media support for a removable  
hard drive if it is first in the scan order.  
With Media Installed provides removable media support wherever  
the drive(s) actually resides.  
One of these choices can be selected by highlighting it and pressing  
Enter.

CHS Mapping – This option defines the cylinder head sector (CHS)  
values that will be mapped onto a disk without pre-existing partitioning  
information. SCSI Plug and Play Mapping is the default value.  
To support interchange with non-compatible systems, there is another  
option that can be selected by choosing CHS Mapping and then moving  
the cursor to Alternate CHS Mapping.  
Note:  
has been partitioned with the FDISK command.  
To remove partitioning, two options are available:  
Reformat the disk using the Format Device option. See Section  
3.2.3, “Device Selections Menu,below.  
Use the FDISK/MBR command at the C:\ prompt, where MBR  
represents master boot record.  
Important: Reformatting the disk or using FDISK/MBR erases all  
partitioning and data that exists. Be careful when using  
either the Format utility or the FDISK/MBR command that  
you target the correct disk.  
After clearing the partitions and data, it is necessary to reboot  
and clear memory or the old partitioning data will be reused.  
Spinup Delay (seconds) – This option allows the user to stagger  
spinups for a longer period of time to balance the total current load. The  
default value is 2 seconds, with choices between 1 and 10 seconds.  
This is a power management feature designed to accommodate disk  
devices that may have heavy current load during power up. If multiple  
drives are being powered up simultaneously and drawing heavy current  
loads, then this option staggers the spinups to limit startup current.  
Secondary Cluster Server – This option allows the user to enable an  
adapter to join a cluster of adapters without doing any SCSI bus resets.  
This is a requirement for Microsoft Cluster Server. The default value is  
No with an alternate option of Yes.  
Termination – This option allows the user to have termination control  
providing an adapter has controllable termination. The default value is  
Autotermination. The alternate value is Off.

Sync Rate (Mbytes/s) – This option defines the maximum data transfer  
rate the host adapter will attempt to negotiate. The host adapter and a  
SCSI device must agree to a rate they can both handle.  
Width (bits) – This option defines the maximum SCSI data width the  
host adapter will attempt to negotiate. The host adapter and a SCSI  
device must agree to a width they can both handle. Only host adapters  
that can do 16-bit data transfers have this option enabled.  
Disconnect – SCSI devices have the ability to disconnect from the  
initiator during an I/O transfer. The disconnect option frees the SCSI bus  
to allow other I/O processes. This option tells the host adapter whether  
or not to allow a device to disconnect. Some devices run faster with  
disconnects enabled (typically newer devices), while some run faster with  
disconnects disabled (typically older devices).

Read/Write I/O Time-Out (seconds) – This option sets the amount of  
time the host adapter waits for a read, write, or seek command to  
complete before trying the I/O transfer again. Since this provides a  
safeguard allowing the system to recover if an I/O operation fails, it is  
recommended that you always set the time-out to a value greater than  
zero.  
Note:  
If the time-out is set to zero, then the I/O will never time-out.  
Scan for Device at Boot Time – Set this option to No when there is a  
device you do not want to be available to the system. Also, on a bus with  
only a few devices attached, you can speed up boot time by changing  
this setting to No for all unused SCSI IDs.  
Scan for SCSI Logical Units (LUNs) – Set this option to Noif you have  
problems with a device that responds to all LUNs whether they are  
occupied or not. For example, if there is a SCSI device with multiple  
LUNs but you do not want all of those LUNs to be available to the  
system, then set this option to No. This will limit the scan to LUN 0 only.  
Queue Tags – This option allows the user to enable or disable the  
issuing of queue tags during I/O requests when your device driver can  
do this.  
Initial Boot – This option allows any device attached to the first adapter  
to become the boot device. It provides the users of non-BBS personal  
computers some of the flexibility of a BBS machine.  
Format – If enabled, this option allows you to low-level format a  
magnetic disk drive. Low-level formatting will completely and irreversibly

A.2 Operational Environment  
The LSIU80ALVD is designed for use in PCI computer systems. The  
SDMS operates the board, but the design of the board does not prevent  
the use of other software.  
A.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 2.1 standard.  
Table A.2 and Table A.3 show the signal assignments.  
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 V pins are used to  
I/O  
differentiate between a 5 V or a 3.3 V PCI environment.

SCSI Configured AutoMatically. A method to automatically allocate SCSI  
IDs using software when SCAM compliant SCSI devices are attached.  
Small Computer System Interface. A specification for a high-performance  
peripheral bus and command set. The original standard is referred to as  
SCSI-1.  
SCSI-2  
SCSI-3  
The current SCSI specification which adds features to the original  
SCSI-1 standard.  
The SCSI specification which adds features to the SCSI-2 standard.  
B-5  
 
SCSI Bus  
A host adapter and one or more SCSI peripherals connected by cables  
in a linear chain configuration. The host adapter may exist anywhere on  
the chain, allowing connection of both internal and external SCSI  
devices. A system may have more than one SCSI bus by using multiple  
host adapters.  
SCSI Device  
SCSI ID  
Any device that conforms to the SCSI standard and is attached to the  
SCSI bus by a SCSI cable. This includes SCSI host adapters and SCSI  
peripherals.  
A way to uniquely identify each SCSI device on the SCSI bus. Each SCSI  
bus has eight available SCSI IDs numbered 0 through 7 (or 0 through 15  
for Wide SCSI). The host adapter usually gets the highest ID, (7 or 15)  
giving it priority to control the bus.  
SCSI SCRIPTS  
A SCSI programming language that works with the SCRIPTS processor  
that is embedded on the LSI53C8XX device. These SCRIPTS reside in  
in host computer system memory.  
SCRIPTS  
Processor  
The SCRIPTS processor allows users to fine tune SCSI operations with  
regard to unique vendor commands or new SCSI specifications. The  
SCRIPTS processor fetches SCRIPTS instructions from system memory  
to control operation of the LSI53C8XX device.  
SDMS  
Storage Device Management System. An LSI Logic software product that  
manages SCSI system I/O.  
Single-Ended  
SCSI  
A hardware specification for connecting SCSI devices. It references each  
SCSI signal to a common ground. This is the most common method (as  
opposed to differential SCSI which uses a separate ground for each  
signal).  
STA  
SCSI Trade Association. A group of companies that cooperate to  
promote SCSI parallel interface technology as a viable mainstream I/O  
interconnect for commercial computing.  
Synchronous  
Data Transfer  
One of the ways data is transferred over the SCSI bus. Transfers are  
clocked with fixed frequency pulses. This is faster than asynchronous  
data transfer. Synchronous data transfers are negotiated between the  
SCSI host adapter and each SCSI device.  
System BIOS  
Controls the low-level POST (Power-On Self-Test), and basic operation  
of the CPU and computer system.  
B-6  
Glossary of Terms and Abbreviations  
 
Ultra SCSI  
A standard for SCSI data transfers. It allows a transfer rate of up to  
20 Mbytes/s over an 8-bit SCSI bus and up to 40 Mbytes/s over a 16-bit  
SCSI bus. STA (SCSI Trade Association) supports using the term “Ultra  
SCSI” over the older term “Fast-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. STA (SCSI Trade Association) supports using the term “Ultra2  
SCSI” over the term “Fast-40”.  
VCCI  
VDE  
Voluntary Control Council for Interference.  
Verband Deucher Elektroniker (Association of German Electrical  
Engineers).  
Virtual Memory  
Wide SCSI  
Space on a hard disk that can be used as if it were RAM.  
A SCSI-2 feature allowing 16-bit or 32-bit transfers on the SCSI bus. This  
dramatically increases the transfer rate over the standard 8-bit SCSI bus.  
Wide Ultra SCSI The SCSI Trade Association (STA) term for SCSI bus width 16-bits, SCSI  
bus speed maximum data rate 40 Mbytes/s.  
Wide Ultra2  
SCSI  
The SCSI Trade Association (STA) term for SCSI bus width 16-bits, SCSI  
bus speed maximum data rate 80 Mbytes/s.  
Word  
A two byte (or 16-bit) unit of information.
