Intel® RAID Controller SRCSATAWB Hardware User’s Guide v

1 Overview

The Intel® RAID Controller SRCSATAWB is a high-performance intelligent PCIExpress* SATA RAID controller that offers reliability, high performance, and faulttolerant disk subsystem management. This is an RAID solution meets the internal storage needs of workgroup, department, or enterprise systems to use cost-effective SATA media.

As a third generation PCI Express storage controller, the Intel SRCSATAWB addresses the demand for increased data throughput and scalability requirements across entry-level and midrange server platforms.

The controller can be connected to up to eight drives directly and allows the use of expanders to connect to additional drives. See the ANSI SAS standard, version 1.0 specification for more information about the use of expanders.

SATA is a 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.

RAID Controller

Intel® RAID Controller SRCSATAWB

The Intel® RAID Controller SRCSATAWB is an intelligent low-profile RAID adapter with an integrated LSI* 1078 RAID-On-Chip chipset, providing both a SATA controller and a RAID engine. With 128 MB RAM built onto the board and eight independent ports using two SFF-8087 mini multi-lane connectors, this controller supports up to 16 enterprise-class SATA devices and 64 logical drives. The PCI-Express* connector fits into an x4 or x8 PCI-Express slot capable of 2.5 Gbps per lane over PCI Express* x4 with a

3.0 Gbps point to point transfer rate.

Protocol Support

• Serial ATA (SATA) protocol defined by the Serial ATA specification, version 1.0a.

• SATA II Protocol: Communication with other SATA II devices.

• Serial Management Protocol (SMP): Topology management information sharing

with expanders.

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

1 Intel® RAID Controller SRCSATAWB Hardware User’s Guide

Operating System Support

• Windows Server 2003*, Windows 2000* Enterprise Server, SP4 and Windows XP*.

• Red Hat* Enterprise Linux 3.0 and 4.0.

• SuSE* Linux Enterprise Server 9, SP1-3 and SLES 10.

The operating systems supported may not be supported by your server board. See the tested operating system list for your server board at http://support.intel.com/support/motherboards/server/. See also the tested hardware and operating system list for the RAID Controller SRCSATAWB to make sure the RAID card supports your operating system.

Usability

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

• Small, thin cabling with serial point-to-point 3.0 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 (def), 128, 256, 512 KB or 1 GB.

• 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.

• 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.

Intel® RAID Controller SRCSATAWB Hardware User’s Guide 2

Redundancy and Error Handling

• In-band and out-of-band SES2.

• Enclosure management support.

• Activity and 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 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)

3 Intel® RAID Controller SRCSATAWB Hardware User’s Guide

• Redundancy through:

— Configuration stored in nonvolatile RAM and on the drives (COD). — Hot-swap support. — Optional battery backup for cache memory. Controller provides fast or trickle

charges.

SATA Features of the 1078 Controller

• Provides eight independent phys, each supporting 3.0 Gbps SATA data transfers.

• Scalable interface that supports up to 16 physical devices and 64 logical devices via

expanders.

• Supports SSP to enable communication with other SATA devices.

• Supports SMP to communicate topology management information.

• Supports single PHY or wide ports consisting of 2, 3, or 4 PHY within one quad

port.

• Allows addressing of multiple SATA targets through an expander if using SATA 2.0-

compliant hard disk drives.

• Allows multiple initiators to address a single target (in a fail-over configuration)

through an expander.

Intel® RAID Controller SRCSATAWB Hardware User’s Guide 4

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 a logical 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

• With OCE migrations supported are RAID 0 to RAID 1, RAID 0 to RAID 5, RAID

1 to RAID 5.

Beep Codes

• Short beep, 1 second on, 1 second off. Array is degraded but no data lost.

• Long beep, 3 seconds on, 1 second off. Array has failed. 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 alarm, choose Enable Alarm.

To disable alarm only until the next event or until next power cycle, choose Silence Alarm.
