PCI Express* Architecture
PCI Express is a local bus system designed to increase data transfers without slowing
down the central processing unit (CPU). You can install the RAID Controller
SRCSAS18E in a PCI Express computer system that has a standard bracket type. With
this adapter in your system, you can connect SAS and SATA devices over the bus.
PCI Express goes beyond the PCI specification in that it is intended as a unifying I/O
architecture for various systems: desktops, workstations, mobile, server, communications,
and embedded devices.
