3.1.5 LSI22320 Dual Channel Host Adapters
The LSI22320 series of host adapters are dual channel Ultra320 SCSI
host adapters that provide two Ultra320 SCSI channels. The SCSI
Channel A interface is made through connectors J2 and J6. The SCSI
Channel B interface is made through connectors J3 and J4. See
Figure 3.5 and Figure 3.6 for details.
Features of the LSI22320 series of host adapters are:
• Two independent Ultra320 SCSI channels
• Four SCSI connectors:
– Two external 68-pin VHDCI connectors
– Two internal 68-pin HD connectors
• LVD/SE termination
• Integrated RAID (IR) solution applies to the “R” cards only
• Fusion-MPT architecture
Details of the LSI22320 series of host adapters are:
• J1: PCI and PCI-X, 64-bit, universal type board edge connector
• J2 and J3: 68-pin VHDCI right-angle external connectors
• J4 and J6: 68-pin HD right-angle internal connectors
• J5: 4-pin low density unshrouded right-angle LED connector
• Subsystem Vendor ID and Subsystem IDs are:
During system initialization, the system loads the ID numbers into the
Subsystem Vendor ID and Subsystem ID registers of the embedded
SCSI controller.
