3.1.3 LSI22320 Dual Channel Host Adapters

The LSI Logic LSI22320 and LSI22320-R are dual channel Ultra320 SCSI to PCI-X 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 3.4 for details.

Features of the LSI22320 and LSI22320-R host adapters are

•two independent Ultra320 SCSI channels

•four SCSI connectors:

–two external 68-pin very high density cable interconnect (VHDCI) connectors

–two internal 68-pin high density connectors

•LVD/SE termination

•LSI Logic Integrated Mirroring (IM) technology for boot volume and operating system protection (IM is for the LSI22320-R only)

•Fusion-MPT architecture
