3 12Gb/s Intel® RAID Controllers User Guide
The controllers support internal storage devices and external storage devices, which allow
you to use a system that supports enterprise-class SAS drives and desktop-class SATA III
drives. Each 12Gb/s Intel
®
RAID Controller can connect to drives directly and can use
expanders to connect to additional drives. Simplified cabling between devices is an
additional benefit.
These devices are compliant with the Fusion-MPT
™
architecture and provides a PCIe x8
interface. Each port on the 12Gb/s Intel
®
RAID Controllers supports SAS devices, SATA
devices, or both, using SSP, SMP, STP, and SATA. The SSP protocol enables the 12Gb/s
Intel
®
RAID Controllers to communicate with other SAS devices. The SATA protocol
enables the 12Gb/s Intel
®
RAID Controllers to communicate with SATA devices.
Note: All of these RAID controllers provide an x8 PCIe 3.0 interface.

RAID Controller Detailed
Descriptions
The 12Gb/s Intel
®
RAID Controllers are described in detail in the following subsections.
Intel
®
RAID Controller RS3WC080
The Intel
®
RAID Controller RS3WC080 is a PCIe 3.0 Low-Profile SAS Controller that
controls eight internal SAS/SATA ports through two SFF-8643 mini-SAS HD-4i internal
connectors.
Intel
®
RAID Module RMS3HC080
The Intel
®
RAID Module RMS3HC080 is a PCI-Express* (PCIe*) 3.0 RAID adapter
whose PCIe* connector is a custom 80-pin connector capable of performance up to 8GT/s
per lane. The Intel
®
RAID Module RMS3HC080 is based on the LSISAS3008 I/O
controller, uses a 16-MB Flash memory device for storing the BIOS and firmware, and
controls eight internal SAS/SATA ports through two SFF-8643 mini-SAS HD-4i internal
connectors.
Intel
®
RAID Controller RS3DC040 and RS3DC080
• The Intel
®
RAID Controller RS3DC040 is a PCIe 3.0 Low-Profile SAS Controller
that controls four internal SAS/SATA ports through one SFF-8643 mini-SAS HD-
4i internal connector.
• The Intel
®
RAID Controller RS3DC080 is a PCIe 3.0 Low-Profile SAS Controller
that controls eight internal SAS/SATA ports through two SFF-8643 mini-SAS HD-
4i internal connectors.
