1Overview
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 SATA
or high-performance SAS media.
As a second-generation PCI Express* RAID controller, the Intel®RAID Controller
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®RAID Smart Battery AXXRSBBU7 provide cached data protection
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

Usability
•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 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® RAID Controller RT3WB080 Hardware User’s Guide
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 read-
modify-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®RAID Web
Console 2; CIM, LEDs, and via alarm.
•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.

Intel® RAID Controller RT3WB080 Hardware User’s Guide 5
SAS/SATA Features of the LSISAS2108 Controller
•Provides eight independent phys, each supporting 6Gb/s and 3Gb/s SATA data
transfers per PHY.
•Scalable interface that supports up to 16 physical devices and 64 virtual drives
through expanders.
•Supports SMP to communicate topology management information.
•Supports single PHY or wide ports consisting of 2, 3, or 4 PHYs within a single
quad port.
•Allows addressing of multiple SATA targets through an expander if using SATA 3.0-
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 an 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
5, and RAID 6 to RAID 0.
•With OCE, migrations supported are RAID 0 to RAID 1, RAID 0 to RAID 5, RAID
5 to RAID 6, RAID 1 to RAID 6, and RAID 1 to RAID 5.
Beep Codes
•Short beep (1 second on, 1 second off): Array has degraded but no data has been
lost.
•Long beep (3 seconds on, 1 second off): Array has failed and data has been lost.
•Short beep (1 second on, 3 seconds off): Using hot spare in rebuild; alarm will
continue during rebuild with a different sound at completion.
To disable the alarm, choose Disable Alarm. To enable the alarm, choose Enable Alarm
To disable the alarm only until the next event or until next power cycle, choose Silence
Alarm.

5. For the first four drives (ports 0 - 3), connect one 4-port combined end of an
internal cable to the right connector (see letter “A” in Figure 3). If you are using
more than four drives without using an expander backplane, connect the second
cable to the left connector (see letter “B” in Figure 3). Connect the other end of the
cables to SATA drives or to the ports on a SATA or SAS backplane (see letter “C”
in Figure 3).
To prevent throughput problems:
✧Use the cables provided or use the shortest possible cable.
✧Do not use cables longer than one meter.
✧Decrease the maximum length by one foot if you are using a backplane.
✧Do not use cross-over cables.
✧Only connect to a SATA drive, SAS or SATA backplane, or an expander
device.
✧Route the cables carefully.
✧Check that the controller and cables are all properly attached.
