1Overview
The Intel®Integrated RAID Module RMS2MH080 (also known as Intel®Integrated
RAID Controller RMS2MH080) 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. 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 RMS2MH080 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 eight drives 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.
The optional Intel®RAID Smart Battery AXXRSBBU7 provides cached data protection
for the RAID module, even during system failures.
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.

•Support for non-disk devices and mixed capacity drives.
•Support for intelligent XOR RAID levels 0, 1, 5, 6, 10, 50, and 60.
•Dedicated or global hot spare with auto rebuild if an array drive fails.
•User defined stripe size per drive: 8, 16, 32, 64, 128, 256, 512, or 1024 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
— No reboot necessary after expansion
•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
•SES2 enclosure management support
•SGPIO enclosure management support
The method of these support mechanisms (in band/out of band/SES connector or sideband
cable ) is explained later in the document.
•Fault indicators per drive.
•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 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 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, and LEDs.
•Multiple cache options allow configuration-specific performance optimization:
— Write-back: Faster because it does not wait for the disk but data will be lost if
power is lost.
— Write-through: Usually slower but ensures data is on the disk.
— Read Ahead: Predicts next read will be sequential and buffers this data into the
cache.
— Non Read Ahead: Always reads from the drive after determining exact location
of each read.
— Adaptive Read Ahead: Reads ahead and caches data only if doing sequential
reads.
— I/O setting. Determines whether read operations check the cache before reading
from disks.
✧Cache I/O: Checks cache first, only reads disk if data is not in the cache.
✧Direct I/O: Reads data directly from disk. (not cache)
•Redundancy through:
— Configuration stored in non-volatile RAM and on the drives (COD).

Intel® Integrated RAID Module RMS2MH080 Hardware User’s Guide 5
— Hot-swap support.
— Optional battery backup for cache memory.
SAS/SATA Features
•Provides eight independent PHYs, each supporting 6.0 Gbps SAS and SATA data
transfers.
•Scalable interface that supports up to 32 physical devices and 64 logical devices via
expanders.
•Supports Serial SCSI Protocol (SSP) to enable communication with other SAS
devices.
•Supports Serial Management Protocol (SMP) to communicate topology
management information.
•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.
Online Capacity Expansion and RAID Level Migration Rules
•Migration must occur to the same or larger capacity configuration.
•Migration cannot occur if there is more than one virtual disk in a logical array.
•Migration and OCE cannot be done on Spanned Arrays (RAID 10, 50, 60).
•Migrations supported are RAID 1 to RAID 0, RAID 5 to RAID 0, RAID 6 to RAID
0.
•With OCE, migrations supported are RAID 0 to RAID 1, RAID 0 to RAID 5, RAID
1 to RAID 5.

Intel® Integrated RAID Module RMS2MH080 Hardware User’s Guide 9
✧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. .

10 Intel® Integrated RAID Module RMS2MH080 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 RMS2MH080 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.
