The ServeRAID M5110 SAS/SATA controller leverages a common
electrical and physical connection interface that is compatible with Serial
ATA technology. The SAS protocols and SATA protocols use a thin,
7-wire connector instead of the 68-wire SCSI cable or 26-wire ATA cable.
The SAS/SATA III connector and cable are easier to manipulate, allow
connections to smaller devices, and do not inhibit airflow. The point-to-
point SATA III architecture eliminates inherent difficulties created by the
legacy ATA master-slave architecture, while maintaining compatibility with
existing ATA firmware.
PCI Express is a local bus system designed to increase data transfers
without slowing down the central processing unit (CPU). You can install
your ServeRAID M5110 controller PCI Express SAS/SATA controller in
PCI Express computer systems with a standard bracket type. With this
controller in your system, you can connect SCSI devices 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.

The ServeRAID M5110 controller uses Fusion-MPT™ architecture for all
major operating systems, thinner drivers, and better performance.
