3.1

Overview

PCI is a high-speed standard local bus for interfacing I/O components to the processor and
memory subsystems in a server. The component height on the top and bottom of the
SRCU42X controller follow the PCI Local Bus Specification, Revision 2.2, and PCI-X
Addendum to the PCI Local Bus Specification, Revision 1.0a. The Intel RAID Controller
SRCU42X is used in PCI-X and PCI computer systems with PCI standard bracket types.
