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.
