Intel RMS3CC040 Hardware User Guide - Page 10

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. 12Gb/s Intel® 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 HD4i 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 HD4i internal connectors. 3 12Gb/s Intel® RAID Controllers User Guide
