3.1.1 LSI20320 Single Channel Host Adapters

The LSI20320, LSI20320-R, LSI20320L and LSI20320H are single
channel Ultra320 SCSI to PCI-X host adapters that provide one Ultra320
SCSI channel. The SCSI Channel A interface for the LSI20320,
LSI20320-R and LSI20320L is made through connectors J1 and J3. See

Figure 3.1

for details. The SCSI Channel A interface for the LSI20320H

is made through connectors J2 and J4. See

Figure 3.2

for details.

Features of the LSI20320 series of host adapters are:

Single Ultra320 SCSI Channel

Two SCSI connectors

One external 68-pin very high density cable interconnect
(VHDCI) connection for LSI20320, LSI20320-R, and LSI20320L

One external 68-pin high density connector for LSI20320H

One internal 68-pin high density connector for all boards

PCI Low Profile bracket (LSI20320L only)

LVD/SE termination

LSI Logic Integrated Mirroring™ (IM) technology for boot volume and
operating system protection (IM is for the LSI20320-R only)

Fusion-MPT Architecture

Details of the LSI20320, LSI20320-R, and LSI20320L host adapters are:

J5: PCI and PCI-X, 64-bit, universal type board edge connector

J1: 68-pin very high density cable interconnect shielded right-angle
external connector

J3: 68-pin high density right-angle internal connector

HDR2: 4-pin low density un-shrouded right-angle LED connector

Subsystem Vendor ID: 0x1000

Subsystem ID: 0x1060

During system initialization, the system loads the ID numbers into the
Subsystem Vendor ID and Subsystem ID registers of the embedded
SCSI controller.
