Intel® Integrated RAID Module RMS25PB0x0 and RMS25CB0x0 Hardware User’s Guide 1
1Overview
The Intel®Integrated RAID Module RMS25PB080, RMS25PB040, RMS25CB080 and
RMS25CB040 are high-performance intelligent PCI Express* 3.0 compliant SAS/SATA
RAID controllers that offer reliability, high performance, and fault-tolerant disk
subsystem management. This is an ideal RAID solution that meets the internal storage
needs of workgroup, department, or enterprise systems to use with cost-effective SATA or
high performance SAS media.
As second generation PCI Express* storage controller, the Intel®Integrated RAID
Module RMS25PB080, RMS25PB040, RMS25CB080 and RMS25CB040 address the
growing demand for increased data throughput and scalability requirements across entry
level, midrange, and enterprise server platforms.
The Intel®Integrated RAID Module RMS25PB080 and RMS25CB080 control 8 internal
SAS/SATA ports through two SFF-8087 Mini SAS x4 internal connectors, and the Intel®
Integrated RAID Module MS25PB040 and RMS25CB040 control 4 internal SAS/SATA
ports through one SFF-8087 Mini SAS x4 internal connectors. 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 AXXRSBBU9 or Intel®RAID Maintenance
Free Backup Unit AXXRMFBU2 provides cached data protection for the RAID
controller, even during system failures.
Benefits of SAS and SATA
SAS is a serial, 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

2Intel® Integrated RAID Module RMS25PB0x0 and RMS25CB0x0 Hardware User’s Guide
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.
Intel®Integrated RAID Module RMS25PB0x0 and
RMS25CB0x0
The Intel®Integrated RAID Module RMS25PB080, RMS25PB040, RMS25CB080 and

Usability
•The the Intel®Integrated RAID Module RMS25PB080 and RMS25PB040 ship with
both a standard and a low-profile bracket.
•Small, thin cabling with serial point-to-point 6.0 Gbps data transfer rates.
•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
— 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.

4Intel® Integrated RAID Module RMS25PB0x0 and RMS25CB0x0 Hardware User’s Guide
Redundancy and Error Handling
•SGPIO enclosure management support
•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).
— Hot-swap support.
— Optional battery backup or maintenance free backup for cache memory.

Intel® Integrated RAID Module RMS25PB0x0 and RMS25CB0x0 Hardware User’s Guide 5
