1 Overview
The Intel® RAID Controller RS2WG160 is a high port-count, high-performance
intelligent PCI Express* 2.0 compliant SAS/SATA RAID controller 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 with cost-effective SATA or high performance SAS media.
As a second generation PCI Express* storage controller, the Intel
RS2WG160 addresses the growing demand for increased data throughput and scalability
requirements across entry level, midrange, and enterprise server platforms.
The controller controls 16 internal SAS/SATA ports through four 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.

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
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® RAID Controller RS2WG160
The Intel® RAID Controller RS2WG160 is an intelligent PCI Express* 2.0 compliant
interface RAID adapter with an integrated LSI* SAS2108 RAID-On-Chip chipset,
providing both a SAS controller and RAID engine. With 512MB RAM built onto the
board, eight independent phys supporting 6-Gbps and 3 Gbps SAS data transfers, the
onboard LSI* SAS2 x36 expander chip, and four SFF-8087 Mini SAS x4 internal
connectors, this controller supports up to 240 enterprise-class SAS or SATA devices and
64 logical drives. The PCI Express* connector fits into an x8 or x16 PCI Express* slot
capable of performance up to 5 Gbps per lane.
The RAID controller is 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*,
and Windows XP*
• Red Hat* Enterprise Linux 4.0 and 5.0
• SuSE* Linux Enterprise Server 9, 10, and 11
• VMWare* ESX 4.0
• Solaris* 10

• Small, thin cabling with serial point-to-point 6.0 Gbps data transfer rates.

• 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:

• Background operating mode can be set for Rebuilds, Consistency Checks,
Initialization (auto restarting Consistency Check on redundant volumes), Migration,

Redundancy and Error Handling
• SES2 enclosure management support
• 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 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
Console 2, CIM, and LEDs.
