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 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.

Configuration Scenarios

You can use the 12Gb/s Intel

RAID Controllers in three main scenarios:

• Low-end internal SATA configuration: In this configuration, use the RAID

controller as a high-end SATA II or SATA III compatible controller that connects up

to eight drives either directly or through a port expander. This configuration is

mostly for low-end or entry servers. An out-of-band I

C bus provides enclosure

management. Side bands of both types of internal SAS connectors support the SFF-

8485 (SGPIO) interface.

• Midrange internal SAS configuration: This configuration is like an internal

SATA configuration, but with high-end SAS drives. This configuration is more

suitable for low-range to midrange servers.

• High-end external SAS/SATA configuration: This configuration is for external

connectivity using SATA II drives, SATA III drives, SAS drives, or combinations of

SATA and SAS drives. External enclosure management is supported through in-

band, SCSI-enclosed storage. The configuration must support STP and SMP.
