1 Overview  
This chapter provides a general overview of the Intel® RAID Controller SASMF8I. It  
consists of the following sections:  
Summary of SAS RAID Controller Features  
Benefits of Serial-Attached SCSI (SAS)  
The Intel® RAID Controller SASMF8I is a high-performance PCI Express* SAS RAID  
controller. It provides reliability, high performance, and fault-tolerant disk subsystem  
management. This is an ideal RAID solution for the internal storage needs of mid to low-  
end servers and workstations for use by workgroups and departmental-sized organizations  
or individuals. The Intel® RAID Controller SASMF8I offers a cost-effective way to  
implement RAID in a server for internal storage.  
The SAS controller allows you to use SATA II and SAS hard disk drives in the same  
system, so you can take advantage of the benefits of each type of drive. The controller  
supports up to eight devices including expander devices. See the ANSI SAS Standard  
Specification, Version 1.0 for more information about the use of expanders.  
As the second generation PCI Express* storage adapter, the Intel® RAID Controller  
SASMF8I addresses the growing demand for increased data throughput and scalability  
requirements across mid to low-end servers and workstations. Simplified cabling between  
drives is an additional benefit.  
Summary of SAS RAID Controller Features  
Note: In this document, the term low-profile refers to the height, not the length, of a PCI add-in  
card.  
The Intel® RAID Controller SASMF8I is a low-profile SAS RAID adapter with:  
An LSI 1068E SAS (including SATA) controller.  
Eight independent internal ports provided via two SFF8087 connectors.  
Support for both enterprise-class SAS devices and enterprise-class SATA II drives.  
Support for up to 8 SAS or SATA II drives and 40 logical drives.  
PCI Express* connector that fits into a x4 PCI Express slot capable of 2.5 Gbps per  
lane over PCI Express* x1, or x4.  
3.0 Gbps point-to-point transfer rate.  
Both a standard and a low-profile bracket.  
Intel® RAID Controller SASMF8I Hardware User’s Guide

The SAS controller supports the ANSI Serial-attached SCSI (SAS) Standard, Version 1.0.  
In addition, the controller supports the Serial ATA (SATA) protocol defined by the Serial  
ATA Specification, Version 1.0a. The SAS controller is a versatile controller that supports  
both the SAS and SATA interfaces and provides the backbone of both server and high-end  
workstation environments.  
Protocols supported include:  
Serial SCSI Protocol (SSP): Communication with other SAS devices.  
SATA II Protocol: Communication with other SATA II devices.  
Serial Management Protocol (SMP): Topology management information sharing  
with expanders.  
Serial Tunneling Protocol (STP) support for SATA II through expander interfaces.  
Usability  
Smaller, thinner cabling with serial point-to-point 3.0 Gbps data transfer rates.  
Allows mixed connections to SAS or SATA II targets.  
Support for non-disk devices and mixed capacity drives.  
Support for software RAID levels 0, 1, 5, and 10.  
Global hot spare with auto rebuild if an array drive fails.  
Fixed RAID stripe size of 64 KB.  
Advanced array configuration and management utilities that provide:  
Drive migration.  
Drive roaming.  
An upgradeable Flash ROM interface.  
Allows for staggered spin-up, hot plug, and lower power consumption.  
User specified rebuild rate (% of system resources to use from 0-100%).  
Warning: Exceeding 50% rate may cause operating system errors caused by waiting  
for controller access.  
Background operating mode can be set for rebuilds, consistency checks,and  
initialization (auto restarting consistency check on redundant volumes).  
Redundancy and Error Handling  
Enclosure management support, including LEDs.  
Activity and fault indicators per drive, port selector (dual-port drives).  
Drive coercion (auto resizing to match existing disks).  
Auto-detection of failed drives with transparent rebuild. Disk activity (I/O to the  
drive) must be present for a missing drive to be marked as failed.  
2
Intel® RAID Controller SASMF8I Hardware User’s Guide  
 
Auto-resume of initialization or rebuild on reboot (the auto rebuild feature must be  
enabled before virtual disk creation).  
Smart initialization automatically checks consistency of virtual disks if there are five  
or more disks in a RAID 5 array, which optimizes performance by enabling read-  
modify-write mode. RAID 5 arrays of only three or overdrives use peer read mode.  
Smart Technology predicts failures of drives and electronic components.  
Commands are retried at least four times.  
Firmware provides best effort to recognize an error and recover from it if possible.  
Failures are logged from controller and drive firmware, SMART monitor, and SAF-  
TE controller.  
Failures are logged in Intel® RAID Web Console 2 or CIM, and can be viewed from  
LEDs.  
Multiple cache options provide choice of speed and redundancy:  
Disk Write Cache: The data written / (done) signal is returned when data is  
written to the drive or only to the drive’s cache.  
On (default): Write back mode enabled. Faster, because it does not wait for  
the disk, but data will be lost if power is lost.  
Off: Write-through mode enabled. Slower, but ensures data is on the disk.  
Read Ahead: Predicts the next read will be sequential and buffers this data into  
the drive’s cache.  
On: Read Ahead mode enabled. Faster in data sequential read mode but  
slower in data random read mode.  
Off: Non-Read Ahead mode enabled. Always reads from the drive after  
determining the exact location of each read.  
Redundancy through:  
Configuration stored in non-volatile RAM and on the drives (COD).  
Hot-swap support.  
SAS and SATA Features  
Provides eight independent PHYs, each supporting 3.0 Gbps and 1.5 Gbps SAS and  
SATA data transfers.  
Scalable interface that supports up to eight direct-attached SAS/SATA devices or  
eight logical devices.  
Transfers data using SCSI information units.  
Supports SSP to enable communication with other SAS devices.  
Supports SMP to communicate topology management information.  
Supports single PHY or wide ports consisting of two, three, or four PHYs within a  
single quad port.  
Intel® RAID Controller SASMF8I Hardware User’s Guide

Allows addressing of multiple SATA targets through an expander if using SATA 2.0-  
compliant hard disk drives.  
Allows multiple initiators to address a single target (in a fail-over configuration)  
through an expander.  
Operating System Support  
The Intel® RAID Controller SASMF8I supports major operating systems, including:  
Microsoft Windows Server 2008*, Microsoft Windows Server 2003*, and Microsoft  
Windows XP*  
Red Hat* Enterprise Linux 4.0 and 5.0  
SuSe* Linux Enterprise Server 9 and 10  
Note: The operating systems supported by this controller may not be supported by your server  
board. See the tested operating system list for your server board at  
http://support.intel.com/support/motherboards/server/. See also the Tested Hardware and  
Operating System List for the Intel® RAID Controller SASMF8I to make sure the RAID  
controller supports your operating system.  
Benefits of Serial-Attached SCSI (SAS)  
SAS is a serial, point-to-point, enterprise-level device interface that leverages the proven  
SCSI protocol set. SAS is a convergence of the advantages of SATA, SCSI, and FC, and is  
the future mainstay of the enterprise and high-end workstation storage markets. SAS  
offers a higher bandwidth per pin than parallel SCSI, and improves signal and data  
integrity.  
The SAS interface uses the proven SCSI command set to ensure reliable data transfers,  
while providing the connectivity and flexibility of point-to-point serial data transfers. The  
serial transmission of SCSI commands eliminates clock skew challenges. The SAS  
interface provides improved performance, simplified cabling, smaller connectors, lower  
pin count, and lower power requirements when compared to parallel SCSI.  
SAS controllers leverage a common electrical and physical connection interface that is  
compatible with Serial ATA technology. The SAS and SATA protocols use a thin, 7-wire  
connector instead of the 68-wire SCSI cable or 40-wire ATA cable. The SAS/SATA  
connector and cable are easier to manipulate, allow connections to smaller devices, and do  
not inhibit airflow. The point-to-point SATA architecture eliminates inherent difficulties  
created by the legacy ATA master-slave architecture, while maintaining compatibility with  
existing ATA firmware.

Figure 2. Attaching cables to the Intel® RAID Controller SASMF8I  
Note: System throughput problems can occur if the SAS cables that come with the RAID  
controller are not used. To minimize the potential for problems:  
Use cables no longer than ten meters for SAS and one meter for SATA. It is  
better to use the shortest possible cables. The cable length should be reduced by  
about one foot (.33 meters) if using a backplane.  
You may connect one device per SATA/SAS cable either as a device or as an  
expander.  
Route SAS cables carefully.  
Use only “straight” SAS cables, not “cross-over” SAS cables.  
6. Replace components you needed to remove to access the PCI Express add-in card  
slot. For instructions, see your server chassis documentation.  
7. Reinstall the chassis cover and reconnect the power cord(s). For instructions, see  
your server chassis documentation.  
8. Reconnect any peripheral items you needed to disconnect.  
9. Turn the power on to the server and hard drives. As the server powers up, listen to  
be sure that the SAS and SATA devices are powered up before or at the same time  
as the computer boots.  
Intel® RAID Controller SASMF8I Hardware User’s Guide

10. Watch the boot process until you see a BIOS message to inform you of the key  
combination to press to enter the Intel® Embedded Server RAID Technology II  
Configuration Utility. A message similar to the following appears:  
®
Press <CTRL> + <E> to run the Intel Embedded Server RAID Technology  
II Configuration Utility.  
This message times out after several seconds. If you miss it, you will pass the option  
to get into the Intel® Embedded Server RAID Technology II Configuration Utility.  
The firmware takes several seconds to initialize and then displays the Intel® RAID  
Controller SASMF8I number and firmware version. The numbering of the controllers  
follows the PCI slot scanning order used by the server board.

Intel® RAID Controller SASMF8I Hardware User’s Guide  
 
Connecting the Cables  
This section describes the cables used on the SAS controller and provides instructions for  
connecting SAS and SATA hard disk drives to the SAS RAID controller.  
Note: Use only “straight” SAS cables, not “cross-over” SAS cables.  
The cable supplied with the Intel® RAID Controller SASMF8I is for SATA drives or a  
SAS backplane connection.  
A SATA connector consists of a signal connector and a power connector. The SAS  
connector adds a bridge (primary physical link) between the signal connector and the  
power connector. This means SAS backplane connectors can accept either drive type, but  
SATA backplane connectors can ONLY accept SATA drives. Figure 3 shows these  
connectors.  
Figure 3. SAS and SATA Plugs and SAS Backplane Connector  
Configuring the Storage Adapter  
After installing the Intel® RAID Controller SASMF8I, you must configure the storage  
adapter and install the operating system driver. The Intel® IT/IR RAID Intel® IT/IR RAID  
Software Users Guide instructs you on the configuration options and how to set them on  
your Intel® RAID Controller SASMF8I, and provides detailed installation instructions for  
operating system drivers.
