1 Overview

The Intel® RAID Controller RT3WB080 is a high-performance, intelligent PCI Express*

2.0-compliant SATA III 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 cost-effective SAT A or high-performance SAS media.

As a second-generation PCI Express* RAID controller, the Intel RT3WB080 addresses the growing demand for increased data throughput and scalability requirements across mid-range and enterprise-class 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 Specification, Version 2.0.

SATA is serial, point-to-point device interface that uses simplified cabling, smaller connectors, lower pin counts, and lower power requirements than parallel SCSI.

The optional Intel for the RAID controller, even during system failures.

Intel® RAID Controller RT3WB080

The Intel® RAID Controller RT3WB080 is an intelligent, low-profile RAID adapter with an integrated LSI SAS2108 RAID-On-Chip chipset, providing both a SATA controller and RAID engine. With 256-MB RAM built onto the board and eight independent ports supporting 6Gb/s and 3Gb/s SATA data transfers using two SFF-8087 mini multi-lane connectors, this controller supports up to 16 enterprise-class SATA devices and 64 virtual drives. The PCI Express* connector fits into an x8 or x16 PCI Express* slot capable of performance up to 5 Gb/s per lane. The RAID controller is designed to fit the following

All operating systems supported by the RAID controller may not be supported by your server board. To verify compatibili ty, see the Tested Operating System List for your server board at http://support.intel.com/support/motherboards/server/.

Usability

To make sure the RAID controller supports your operating system, refer to the T ested Hardware and Operating System List for the Intel

RAID Controller RT3WB080.

• The card ships with both a standard and a low-profile bracket.

• Small, thin cabling with up to 6.0 Gb/s serial, point-to-point 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 provides:

— Online Capacity Expansion (OCE) adds space to existing drive or new drive.

See Appendix A 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 afte r 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

• In-band and out-of-band SES2.

• Enclosure management support.

• Support the internal SATA Sideband signal SFF-8485 (SGPIO) interface.

• 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.

• Dirty cache LED plus error reporting for cache write to disk.

• 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, LEDs, and via alarm.

RAID Web

• 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 for cache memory.
