The component height on the top and bottom of the Ultra320 SCSI host adapters follows the PCI Local Bus Specification, Revision 2.2, PCI-X Addendum to the PCI Local Bus Specification, Revision 1.0a, and PCI Express to PCI/PCI-X Bridge Specification, Revision 1.0. The Ultra320 SCSI host adapters are used in PCI/PCI-X and PCI Express computer systems with PCI standard and PCI low profile bracket types.

3.1.1 LSI20320 Single Channel Host Adapters

The LSI20320 series of host adapters are single channel Ultra320 SCSI host adapters that provide one Ultra320 SCSI channel. The SCSI Channel A interface is made through connectors J1 and J3.

Features of the LSI20320 series of host adapters are:

•single Ultra320 SCSI channel

•two SCSI connectors

–one external 68-pin very high density cable interconnect (VHDCI) connection

–one internal 68-pin high density (HD) connector

•PCI low profile bracket (LSI20320L-R only)

•LVD/SE termination

•Integrated RAID (IR) solution applies to the ‘‘R’’ cards only

•Fusion-MPT architecture

Details of the LSI20320 series of host adapters are:

•J5: PCI and PCI-X, 64-bit, universal type board edge connector

•J1: 68-pin VHDCI shielded right-angle external connector
