3.1

Overview

The Intel

RAID Controller SRCU42E is used in systems that have a x8 PCI Express* slot

with a PCI-standard bracket type.

PCI Express goes beyond the PCI specification in that it is intended as a unifying I/O
architecture for a variety of systems, including desktops, workstations, mobile, server,
communications, and embedded devices.
