3.1Ultra320 SCSI to PCI-X Host Adapters

PCI-X is a high-speed standard local bus for interfacing a number of I/O components to the processor and memory subsystems in a high-end PC. The component height on the top and bottom of the Ultra320 SCSI host adapters follow the PCI Local Bus Specification, Revision 2.2 and PCI-X Addendum to the PCI Local Bus Specification, Revision 1.0a. The Ultra320 SCSI host adapters are used in PCI-X and PCI computer systems with PCI standard and PCI low profile bracket types.Table 3.1 lists the LSI Logic Ultra320 SCSI host adapters.
