3.1.5 LSI22320E Dual Channel Host Adapters
The LSI22320E 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 connector J2. The SCSI Channel B
interface is made through connectors J3 and J5. See Figure 3.6 for details.
Features of the LSI22320E and LSI22320E-R host adapters are:
• two independent Ultra320 SCSI channels
• three SCSI connectors:
– two external 68-pin VHDCI connectors
– one internal 68-pin HD connectors
• LVD/SE termination
• Integrated RAID (IR) solution applies to the ‘‘R’’ cards and the
B Channel only
• Fusion-MPT architecture
Details of the LSI22320 series of host adapters are:
• J1: PCI-Express x4 lanes, serial board edge connector
• J2 and J3: 68-pin VHDCI right-angle external connectors
• J5: 68-pin HD right-angle internal connectors
• HDR2: 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.
Figure 3.6 illustrates the LSI22320E and the LSI22320E-R host adapter.
