Installing any of these adapters in your PCI or PCI-X system allows you to connect up to 15 SCSI devices per channel over a SCSI bus. You can use the Ultra320 SCSI boards in PCI-X computer systems with a standard bracket type.

Ultra320 SCSI to PCI-X Host Adapters 1-1

To utilize Ultra320 SCSI performance, you must connect only Low Voltage Differential (LVD) devices to the host adapter. If you connect single-ended (SE) devices and LVD devices, the entire bus will drop to the lower SE speed, limiting bus performance to Ultra SCSI.

The Ultra320 SCSI host adapters support all major operating systems, such as Windows (NT 4.0, 2000, NET and XP), Linux, NetWare, UnixWare, SCO OpenServer 5.X, OS/2, and Solaris. Other software support includes SureLINK™ Domain Validation on Windows systems. Domain Validation ensures data integrity by intelligently testing the network before completing negotiation.

The Ultra320 SCSI host adapters utilize Fusion-MPT™ architecture for all major operating systems, which allows for thinner drivers and better performance. To obtain a device driver that supports your operating system, contact the LSI Logic technical support team at 719-533-7230 or visit our website at http://www.lsilogic.com.

Step 4. Be sure to tighten the bracket screw into the bracket securely

before you connect the internal and external SCSI devices.

2.2 SCSI Device Cables

For reliable Ultra320 operation, be sure to use an Ultra320 rated SCSI cable. The Ultra320 SCSI cable also has built-in low voltage differential and single-ended termination. This built-in feature is included because most Ultra320 SCSI hard disk drives are not made with on-board low voltage differential termination.

2.2.1 Internal SCSI Cables

You can connect all internal SCSI devices to the host adapter with an unshielded, twisted pair, 68-pin ribbon cable. Some 68-pininternal cables come with a low voltage differential and single-ended terminator on one end, which must be furthest from the host adapter. Figure 2.3 and

Figure 2.4 show internal cables with and without a terminator.

SCSI Device Cables 2-5

2.3 Connecting SCSI Devices

This section explains how to connect internal and external SCSI devices to the Ultra320 SCSI host adapters.

2.3.1 Connecting Internal SCSI Devices

This section provides step-by-step instructions for connecting internal SCSI devices. The ﬁgures show the LSI22320 host adapter, which has two internal connectors and two external connectors. Other Ultra320 SCSI host adapter models have different numbers of connectors. Refer to Section 2.2.1, “Internal SCSI Cables,” page 2-4 for examples of internal cables.

If you only need to connect external devices, skip to Section 2.3.3,

“Connecting External SCSI Devices,” page 2-9. Otherwise follow these

steps: Step 1. Plug the 68-pin connector on the end of the SCSI ribbon cable

into the internal connector on the host adapter board.

Figure 2.6 shows how to do this.

Figure 2.6 Connecting Internal SCSI Cable to Host Adapter

2-6 Detailed Host Adapter Installation

Step 2. Plug the 68-pin connector on the other end of the internal SCSI

ribbon cable into the SCSI connector on the internal SCSI

device. Figure 2.7 shows how to do this.

Figure 2.7 Connecting Multiple Internal SCSI Devices

Step 3. If you have another internal SCSI device, connect the internal

SCSI ribbon cable to it. Figure 2.7 shows how to do this. You

can connect other devices if the cable has more connectors.

The Ultra320 SCSI host adapters support up to 15 SCSI

devices connected to each SCSI channel. Step 4. Be sure that termination is enables at the end of the cable that

is farthest away from the SCSI host adapter. See Section 2.4,

Connecting SCSI Devices 2-7

“Terminating the SCSI Bus,” page 2-11 for more information

about SCSI bus termination.

2.3.2 Connecting the LED Cable

Most computer cabinets have a front panel LED. When properly connected, the front panel LED lights when there is activity on the SCSI bus.

Connect the LED cable to connector J5 on the host adapter, as shown in Figure 2.8. Connector J5 is not keyed.

Figure 2.8 SCSI LED Connector

LED Cable

The orientation of the LED cable does not matter as long as all four pins are connected. 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 J5.

If your LED cables has only two wires, place the connector on one end or the other of J5. If the LED does not light when there is SCSI activity, move the connector to the other half of J5.

2.3.3 Connecting External SCSI Devices

This section provides step-by-step instructions for connecting external SCSI devices. Refer toSection 2.2.2, “External SCSI Cable,” page 2-5 for examples of external cables.

Step 1. Plug the 68-pin VHDCI connector on one end of a shielded

external high density cable into the host adapter’s external

SCSI connector. This connector is exposed on the back panel

of your computer. Step 2. Plug the 68-pin VHDCI connector on the other end of the

shielded external SCSI cable into the SCSI connector on the

ﬁrst external SCSI device.

Figure 2.9shows how to connect a singleexternal SCSI device.

If you have the correct cable, it will match the external

connector.

Step 3. Connect any additional SCSI devices to one another with

shielded external SCSI cables. You will need a separate SCSI

cable for each additional device.

Figure 2.10 shows how to connect multiple external SCSI

devices.

Figure 2.10 Connecting Multiple External SCSI Devices

Enable termination on the device at the end of the bus.

Disable termination on all devices not at the end of the bus.

Step 4. Be sure that termination is enabled on the last external SCSI

device as shown in Figure 2.10. See Section 2.4, “Terminating

the SCSI Bus,” page 2-11 for more information about SCSI bus

termination.

2-10 Detailed Host Adapter Installation

Host Adapter Automatically Terminated

2.4 Terminating the SCSI Bus

The SCSI bus contains all the devices that you connect with SCSI cables. When you connect the ﬁrst and last physical SCSI devices on the ends of the SCSI bus, you must have termination active. You must remove or disable termination on all other SCSI devices on the same bus.

If you connected only internal SCSI devices on a bus, the host adapter automatically terminates itself. If you connected only external SCSI devices on a bus, the host adapter also terminates automatically. Automatic termination occurs because the host adapter connection is at the end of the SCSI bus. If you connect both internal and external SCSI devices on a bus, the host adapter automatically disables its termination. This occurs because the host adapter is in the middle of the SCSI bus.

2.4.1 LSI20320 Host Adapter Termination

The LSI20320, LSI20320H, LSI20320L, and LSI20320-R host adapters provide active termination with an automatic means of enabling and disabling the termination. When you connect SCSI devices to both the internal and external connectors, host adapter termination is automatically disabled.

2.4.2 LSI21320 Host Adapter Termination

The LSI21320(-R) host adapter provides active termination with an automatic means of enabling and disabling the termination. When you connect SCSI devices to the internal and external connectors on Channel A, termination for Channel A is automatically disabled.

Channel B has only one SCSI connector. Channel B termination is always enabled.

2.4.3 LSI22320 Host Adapter Termination

The LSI22320(-R) host adapter provides active termination with an automatic means of enabling and disabling the termination. When you connect SCSI devices to both the internal and external connectors on a given channel, termination for that channel is automatically disabled.

Terminating the SCSI Bus 2-11

2.5 Setting SCSI IDs

SCSI IDs identify each SCSI device on the SCSI bus. Each SCSI ID on a given bus must be unique. The IDs are 0 through 15 for a 16-bit bus. The preset host adapter ID setting is 7 which gives the highest priority to the host adapter.

If you plan to boot your computer from a SCSI hard disk drive, you must assign SCSI ID 0 to the drive. Normally, you do not change the host adapter SCSI ID setting from its default value.

Typically, you set the peripheral device SCSI IDs with jumpers or with a switch on the peripheral. You must not duplicate SCSI IDs on a SCSI bus. LSI Logic recommends that you record the SCSI IDs of all SCSI devices. Table 2.1 provides a place to keep this record.

External SCSI Device

Fusion-MPT Architecture

A SCSI device installed outside the computer cabinet. These devices are connected together using speciﬁc types of shielded cables.

Fusion-MPT (Message Passing Technology) architecture consists of several main elements: Fusion-MPT ﬁrmware, the Fibre Channel and SCSI hardware, and the operating system level driversthat support these architectures. Fusion-MPT architecture offers a single binary, operating system driver that supports both Fibre Channel and SCSI devices.

Ultra320 SCSI to PCI-X Host Adapters A-1

Host The computer system in which a SCSI host adapter is installed. It uses

the SCSI host adapter to transfer information to and from devices attached to the SCSI bus.

Host Adapter A circuit board or integrated circuit that provides a device connection to

the host.

Internal SCSI Device

A SCSI device installed inside the computer cabinet. These devices are connected to one another with an unshielded ribbon cable.

PCI and PCI-X Peripheral Component Interconnect. A high performance local bus

speciﬁcation that allows connection of devices directly to computer memory. The PCI Local Bus allows transparent upgrades from a 32-bit data path at 33 MHz to a 64-bit data path at 33 MHz; from a 32-bit data path at 66 MHz to a 64-bit data path at 66 MHz; and from a 32-bit data path at 133 MHz to a 64-bit data path at 133 MHz (1064 Mbytes/s peak).

Peripheral Device

A piece of hardware (such as a disk drive, printer, or CD-ROM) used with a computer and under the computer’s control. SCSI peripheral devices are controlled through a SCSI host adapter.

SCSI Bus A host adapter and one or more SCSI devices connected by cables in a

linear conﬁguration. The host adapter may exist anywhere on the bus, allowing connection of both internal and external SCSI devices. A system may have more than one SCSIbus by usinga multi-channel host adapter or by using multiple host adapters.

SCSI Device Any device that conforms to the SCSI standard and is attached to the

SCSI bus by a SCSI cable. This includes SCSI host adapters, SCSI disk drives, SCSI CD-ROMS drives, and so on.

SCSI ID An identiﬁer that addresses speciﬁc devices on the SCSI bus and

determins device selection when multiple devices contend for ownership of the SCSI bus. Wide SCSI buses support SCSI IDs 0 through 15, and narrow SCSI buses support SCSI IDs 0 through 7. A device gains ownership of the bus according to the priority of its SCSI ID. The order of priority, from highest to lowest, is: 7, 6, 5, 4, 3, 2, 1, 0, 15, 14, 13, 12, 11, 10, 9. The host adapter is usually set to the highest priority SCSI ID, which is SCSI ID 7.

Single-Ended SCSI

A hardware speciﬁcation for connecting SCSI devices. It references each SCSI signal to a common ground. In contrast, differential SCSI uses a separate ground for each signal.
