1 Overview The Intel® RAID Controller RS25AB080 is a high-performance intelligent PCI Express* 3.0 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.
Intel® RAID Controller RS25AB080 The Intel® RAID Controller RS25AB080 is an intelligent, low-profile RAID adapter with an integrated LSI SAS2208 dual-core RAID-On-Chip chipset, providing both a SAS controller and RAID engine. With 1GB RAM built onto a memory board which is connected to the RAID baseboard by default, and eight independent ports supporting 6Gb/s and 3Gb/s SAS data transfers using two SFF-8087 mini multi-lane connectors, this controller supports up to 48 enterprise-class SAS or SATA devices.
Usability • The card ships with both a standard and a low-profile bracket. • The card ships with a 1GB memory board which is already installed onto the RAID controller baseboard as the RAID cache. • • • • • • Small, thin cabling with serial point-to-point 6.0 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.
• 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.
SAS/SATA Features • Provides eight independent phys, each supporting 6Gb/s and 3Gb/s SAS data transfers per PHY. • • • • Scalable interface that supports up to 128 physical devices through expanders. Supports SSP to enable communication with other SAS devices. 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 2.

RAID transactions. Cache mode selection takes immediate effect while the server is online and is available on a per virtual drive basis. The ROC memory controller provides single-bit ECC error correction with multi-bit detection support. The Intel® RAID Controller RS25AB080 supports Super Cap 2 module. Super Cap 2 backup unit is an industrial new technology to dramatically enlarge the life time of the backup unit. There is no need to replace the backup unit with a new one every year.
The drive failure tones repeat until the problem is corrected, or until the alarm is silenced or disabled. The alarm can be silenced or disabled on the controller’s properties page in the BIOS Console or by using the failed drive options pane in the Intel® RAID Web Console 2. Silencing the alarm is temporary. If the cause of failure still exists or if an additional failure is detected, then the alarm sounds again when the system is rebooted. Disabling the alarm is persistent across errors and reboots.

Operating Certifications The RAID controller in this document is qualified to get Microsoft Windows* Winqual certification (WHQL) at product launch. Supported Device Technology The various device technologies supported by the Intel® RAID Controller RS25AB080 is described in the subsections that follow. Support for Hard Disk Drive Devices The Intel® RAID Controller RS25AB080 integrates eight internal high-performance SAS/SATA III ports that support SAS and enterprise-class SATA hard drives.
RAID Functionality and Features Hierarchy The fundamental purpose of a RAID system is to present a usable data storage medium (virtual drive) with some level of redundancy to a host operating system. The Intel® RAID firmware is based on the concept of associating physical drives in arrays and then creating a virtual drive from that array that includes a functional RAID level. To create a virtual drive and present it to the host operating system, the RAID firmware typically follows these steps: 1.
RAID Virtual Drive Status Table 13. RAID Virtual Drive Status Drive State Code Description Optimal Optimal The drive operating system is good. All configured drives are online. Degraded Degraded The drive operating condition is not optimal because one of the configured drives has failed or is offline. Offline Offline The drive is not available to the operating system and is unusable.

Appendix B: Drive Roaming and Drive Migration Install Drive Roaming Drive roaming occurs when the hard drives are changed to different ports on the same controller. When the drives are placed on different ports, the controller detects the RAID configuration from the configuration data on the drives. Note: If you move a drive that is currently being rebuilt, the rebuild operation will restart, not resume. To use drive roaming, follow these steps: 1.
Drive Migration Drive migration moves a configured set of hard drives from one controller to another. The drives must remain on the same port and be reinstalled in the same order as in the original configuration. The controller to which you migrate the drives cannot have an existing configuration. Note: Only complete configurations can be migrated; individual virtual disks cannot be migrated. Drive roaming and drive migration cannot be supported at the same time. To migrate drives, follow these steps: 1.
Appendix C: Installation/Assembly Safety Instructions As you use your computer system, observe these safety guidelines: • Do not operate your computer system with any cover(s) (such as computer covers, bezels, filler brackets, and front-panel inserts) removed. • To help avoid damaging your computer, be sure the voltage selection switch on the power supply is set to match the alternating current (AC) power available at your location.
Additional safety guidelines: • When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. Some cables have a connector with locking tabs; if you are disconnecting this type of cable, press in on the locking tabs before disconnect the cable. As you pull connectors apart, keep them evenly aligned to avoid bending any connector pins. Also, before you connect a cable, make sure both connectors are correctly oriented and aligned.
