1 Overview

The Intel® Integrated RAID Module RMS2AF040 and RMS2AF080 is a highperformance 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 solution that meets the internal storage needs of workgroup, department, or enterprise systems to use cost-effective SATA or high performance SAS media.

SAS Hardware RAID Software Stack. This is a RAID

As a second generation PCI Express* storage controller, the Intel 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.

Integrated RAID

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.

Intel® RMS2AF040 and RMS2AF080

The Intel® Integrated RAID Module RMS2AF040 and RMS2AF080 are intelligent custom board-to-board PCI Express* 2.0 compliant interface RAID adapters with an integrated LSI* LSISAS2008 Processor Chip, providing both a SAS controller and RAID engine. With four (RMS2AF040) or eight (RMS2AF080) independent ports supporting 6Gbps and 3 Gbps SAS data transfers using four or eight individual SAS/SATA connectors, this controller supports up to 32 enterprise-class SAS or SATA devices and 64 logical drives. The PCI Express* connector fits into a 50 pin connector capable of performance up to 5 Gbps per lane.

The RAID modules are designed to fit the following Intel

Protocol Support

Each port on the SAS controllers supports SAS devices, SATA II devices, or both using SSP, SMP, STP, and SATA II as follows:

• Serial SCSI Protocol (SSP) to enable communication with other SAS devices.

• SATA II Protocol to enable communication with other SATA II devices.

• Serial Management Protocol (SMP) to share topology management information

with expanders.

• Serial Tunneling Protocol (STP) support for SATA II through expander interfaces..

Operating System Support

• Windows Server 2008* R2, Windows 7*, Windows Server 2003*, Windows Vista*

• Red Hat* Enterprise Linux 5.0

• SuSE* Linux Enterprise Server 10 and 11

• VMWare* ESX 4.0

• Solaris* 10

• Support for intelligent XOR RAID levels 0, 1, 5, 10, and 50.

• Dedicated or global hot spare with auto rebuild if an array drive fails.

• User-defined strip size per drive: 8, 16, 32, or 64 KB.

• Advanced array configuration and management utilities provide:

• 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 readmodify-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.
