Intel

RAID Controller RS3MC044

The Intel

RAID Controller RS3MC044 is a PCIe 3.0 Serial-Attached SCSI/SATA Disk

Array Controller that controls four internal SAS/SATA ports through one SFF-8643 mini-

SAS HD-4i internal connector and four external SAS/SATA ports through one SFF-8644

mini-SAS HD-4e external connector.

Intel

RAID Controller RS3SC008

The Intel

RAID Controller RS3SC008 is a PCIe 3.0 Serial-Attached SCSI/SATA Disk

Array Controller that controls eight external SAS/SATA ports through two SFF-8644

mini-SAS HD-4e external connectors.

Intel

RAID Module RMS3CC080

The Intel

RAID Module RMS3CC080 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 RMS3CC080 is based on the LSISAS3108 ROC

controller, uses 1GB of DDR3 1866MHz memory as cache, and 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.
