1Overview
The Intel®Integrated RAID Module RMS2AF040 and RMS2AF080 is a high-
performance intelligent custom board-to-board PCI Express* 2.0 compliant SAS/SATA
RAID module that offers reliability, high performance, and fault-tolerant disk subsystem
management based on the Intel®SAS Hardware RAID Software Stack. This is a RAID
solution that meets the internal storage needs of workgroup, department, or enterprise
systems to use cost-effective SATA or high performance SAS media.
As a second generation PCI Express* storage controller, the Intel®Integrated RAID
Module RMS2AF040 and RMS2AF080 addresses the growing demand for increased data
throughput and scalability requirements across entry level, midrange, and enterprise
server platforms.
The controller can be connected to up to four drives (RMS2AF040) or eight drives
(RMS2AF080) directly and allows the use of expanders to connect to additional drives.
For more information about the use of expanders, see the ANSI SAS Standard, version 2.0
specification.
SATA and SAS are serial, point-to-point, device interfaces that use simplified cabling,
smaller connectors, lower pin counts, and lower power requirements than parallel SCSI.
Benefits of SAS and SATA
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 than 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, connect to smaller devices, and do not
inhibit airflow. The point-to-point SATA architecture eliminates difficulties created by the
legacy ATA master-slave architecture, while maintaining compatibility with existing ATA
firmware.

•User-defined strip size per drive: 8, 16, 32, or 64 KB.
•Advanced array configuration and management utilities provide:
— Online Capacity Expansion (OCE) adds space to existing drive or new drive.
See Appendix A: Drive Roaming and Drive Migration Install for limitations on
OCE and RAID migration.
— Online RAID level migration (upgrade of RAID mode may require OCE)
— Drive migration
— Drive roaming

4Intel® Integrated RAID Module RMS2AF040 and RMS2AF080 Hardware User’s Guide
— No reboot necessary after expansion
— Load Balancing
•Upgradeable Flash ROM interface.
•Allows for staggered spin-up, hot-plug, and lower power consumption.
•User specified rebuild rate (percent of system resources to use from 0-100%).
Caution: Exceeding 50% rate may cause operating system errors due to waiting for
controller access.
•Background operating mode can be set for Rebuilds, Consistency Checks,
Initialization (auto restarting Consistency Check on redundant volumes), Migration,
OCE, and Patrol Read.
Redundancy and Error Handling
•SGPIO, In-band and out-band SES2 Enclosure management support.
•Drive coercion (auto-resizing to match existing disks).
•Auto-detection of failed drives with transparent rebuild. There must be disk activity
(I/O to the drive) for a missing drive to be marked as failed.
•Auto-resume on reboot of initialization or rebuild (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 four drives use Peer Read mode.
•Smart Technology predicts failures of drives and electronic components.
•Patrol Read checks drives and maps bad sectors.
•Commands are retried at least four times.
•Firmware provides best effort to recognize an error and recover if possible.
•Failures are logged from controller and drive firmware, and SMART monitor.
•Failures are logged in NVRAM, viewable from OS Event Log, Intel® RAID Web
Console 2; CIM, LEDs.
•Access policy:
— RW: allow read and write I/O
— Read Only: allow read I/O only
— Blocked: deny read and write I/O
•Redundancy through:
— Configuration stored in non-volatile RAM and on the drives (COD).
— Hot-swap support.

RMS2AF0x0 Hardware Installation
Requirements
•Intel®Integrated RAID Module RMS2AF040 and RMS2AF080, with the provided
standoffs
•A host system with one available 50-pins PCI Express* 2.0 connector
•Resource CD, which contains drivers and documentation
•SAS or SATA 6.0 hard drives
•Four provided SAS/SATA cables (for cable requirements, see step 6 in “Installing
the RAID Module”)
Note: Intel Corporation strongly recommends using an uninterruptible power supply (UPS).
Installing the RAID Module
To install the RAID Module, follow these steps:
1. Turn off the power to the system, all drives, enclosures, and system components.
Remove the power cord(s).
2. Remove the server cover. For instructions, see your server system documentation.
3. Insert the three barrel standoffs into the matching holes in the server/workstation
board. To locate the matching module card slot on your server/workstation board,
see your server/workstation board documentation.
The Intel®Server Board SR5520UR is shown for illustrative purpose. Actual
standoff hole locations could be different (see Figure 1).
4. Attach the Intel®Integrated RAID Module RMS2AF0x0 to the matching
server/workstation board connector, and press the module card firmly to engage the
barrel standoffs installed in step 3 (see Figure 1). The Intel®RAID Module
RM2AF080 is shown for illustrative purpose (see Figure 2).

8Intel® Integrated RAID Module RMS2AF040 and RMS2AF080 Hardware User’s Guide
Figure 1. Installing the Barrel Standoff
5. Press down gently but firmly to ensure that the card is properly seated in the
connectors, and then insert the three pin standoffs into the barrel standoffs
respectively ( see Figure 2).
Figure 2. Installing Intel®Integrated RAID Module RMS2AF0x0
6. Connect the SAS/SATA cables from the backplane (or hard drives) to the RAID
module (see Figure 3). For information regarding connecting the recommended
Right-angle end or Vertical end of the SAS/SATA cable to the SAS connectors of
the controller, see your server/workstation board or chassis documentation. Make
sure the cables are properly connected to the controller.
Note: System throughput problems can occur if non-standard SAS cables are 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.

10 Intel® Integrated RAID Module RMS2AF040 and RMS2AF080 Hardware User’s Guide
Configuring the RAID Module
To configure the RAID Module, follow these steps:
1. Turn on the system power and check to make sure that the SAS/SATA devices
power up before or at the same time as the system.
2. During the boot, the following BIOS message appears to state the keys that you
need to press to enter the Intel®RAID BIOS Console 2:
Press <CTRL><G> to run BIOS Console 2.
This message times out after several seconds. If you miss it, you need to restart the
system.
After you press the keys to enter the Intel®RAID BIOS Console 2 software, the
firmware takes several seconds to initialize and then display the Intel®Integrated
RAID module RMS2AF040 or RMS2AF080 number and firmware version. The
numbering of the RAID module follows the PCI slot scanning order used by the
server board.
3. Follow the instructions in the Intel®RAID Software User's Guide (Document
Number: D29305-0xx) to configure the RAID module and to install the operating
system drivers.
Replacing a Controller, Resolving a Config Mismatch
To replace the RAID module, see your server system documentation for instructions to
remove and then install an add-in adapter.
If the newly installed RAID module was previously configured, a message appears during
POST, stating that there is a configuration mismatch because the configuration data in the
NVRAM differs from that in the hard drives. Use these steps to resolve the mismatch:
1. Press <Ctrl> + <G> when prompted during boot up to access the BIOS
Configuration Utility.
2. Select Configure > View/Add Configuration to see the NVRAM and drive
configurations.
3. Since the drives contain the correct configuration, use configuration from the disks.
4. Press <Esc> and select YES to update the NVRAM.
5. Exit and reboot.
