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.
