The LSI20160 PCI to Single Channel Ultra160 SCSI Host Adapter

(Figure 3.1) provides one Ultra160 SCSI channel. The LSI20160 board supports Low Voltage Differential (LVD) and Single-Ended (SE) SCSI. The SCSI interface is made through connectors J2 and J4.

The LSI20160 has these features:

•One Ultra160 SCSI channel

•Two connectors

–One external 68-pin VHDCI connection

–One internal 68-pin high density connection

•LVD/SE SCSI termination for the external connection; LVD SCSI only for internal connection
