1 Overview The Intel® SAS Controller RS25GB008 is a high-performance, intelligent PCI Express* 2.0-compliant SAS/SATA II controller offers reliability and high performance. This is an ideal solution for the large capacity storage needs of mid to low-end servers and workstations for use by workgroups and departmental-sized organizations or individuals. Intel® SAS Controller RS25GB008 offers a cost-effective way to attach physical drives to a server for storage.
Intel® SAS Controller RS25GB008 Intel® SAS Controller RS25GB008 integrates the latest enhancements in PCI Express® and SAS technology. The SAS controller supports medium to large capacity server storage applications by connecting a 5GT/s, 8-lane PCI Express bus with two external x4 SFF8088 connectors. The SAS Controller is designed to fit various Intel® Server Boards and systems. For the most up-to-date support list, see the Compatibility section under the link for this Intel® SAS Controller at http://www.
Usability • • • • • • The card ships with both a standard and a low-profile bracket. Upto 6.0 Gb/s serial, point-to-point data transfer rates Support for non-disk devices and mixed capacity drives Upgradeable Flash ROM interface Allows for staggered spin up, hot-plug, and lower power consumption Allows mixed connections to SAS targets or SATA II targets SAS/SATA Features of the LSI* LSISAS2308 Processor Chip See “LSI* LSISAS2308 Processor Chip” for SAS/SATA features of the LSI* LSISAS2308 Processor Chip.

For more information, see http://www.lsi.com/. Note: Some of these chip features may not be supported by Intel® SAS Controller RS25GB008. Flash ROM An 16-MB CFI-compliant flash ROM is used to accommodate firmware and BIOS Console 2 OpROM. Boot Strap ROM (SEEPROM) The serial bootstrap ROM is used to configure the LSI* LSISAS2308 Processor Chip before the server board configures the PCI Express* registers. The bootstrap ROM sets the Phase Lock Loop (PLL) dividers, bootstrap configuration, and so on.
Figure 4. Intel® SAS/SATA Connectors SAS/SATA Connector Pin-out Signal names are with respect to the host. The device connected to the host reverses the signal names. Transmit pins connect to receive pins on the other device. The SAS/SATA connector is keyed at pin 1. These pin-outs for the serial ATA connector are not compatible with the legacy PATA connector.

The supply voltages are 3.3 V ± 9 percent from PCI edge connector only. The maximum power for the +3.3 V rail is 18 W. The +3.3 V rail is used by the 3.3 V logic circuitry and also used to generate the other required voltage rails of +1.0 V and +1.8 V.
Management Protocol (SMP), and Serial Tunneling Protocol (STP). The SSP protocol enables communication with other SAS devices. STP allows the SAS controller to communicate with SATA devices using the SATA commands. SAS Expander Support The Intel® SAS Controller RS25GB008 supports LSI* expanders and Maxim SAS expanders, that are used as a component in Intel enclosures. Other expanders may be supported post launch, based on market conditions and customer requirements.
Appendix A: 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.
English Read all caution and safety statements in this document before performing any of the instructions. See also Intel® Server Boards and Server Chassis Safety Information on the Resource CD and/or at http://www.intel.com/support/motherboards/server/sb/cs-010770.htm. The power button on the system does not turn off system AC power. To remove AC power from the system, you must unplug each AC power cord from the wall outlet or power supply.
A microprocessor and heat sink may be hot if the system has been running. Also, there may be sharp pins and edges on some board and chassis parts. Contact should be made with care. Consider wearing protective gloves. Deutsch Lesen Sie zunächst sämtliche Warn- und Sicherheitshinweise in diesem Dokument, bevor Sie eine der Anweisungen ausführen. Beachten Sie hierzu auch die Sicherheitshinweise zu Intel-Serverplatinen und -Servergehäusen auf der Ressourcen-CD oder unter http://www.intel.
SICHERHEITSMASSNAHMEN: Immer wenn Sie die Gehäuseabdeckung abnehmen um an das Systeminnere zu gelangen, sollten Sie folgende Schritte beachten: 1. Schalten Sie alle an Ihr System angeschlossenen Peripheriegeräte aus. 2. Schalten Sie das System mit dem Hauptschalter aus. 3. Ziehen Sie den Stromanschlußstecker Ihres Systems aus der Steckdose. 4. Auf der Rückseite des Systems beschriften und ziehen Sie alle Anschlußkabel von den I/O Anschlüssen oder Ports ab. 5.
Notez que le commutateur CC de mise sous tension /hors tension du panneau avant n'éteint pas l'alimentation CA du système. Pour mettre le système hors tension, vous devez débrancher chaque câble d'alimentation de sa prise. C'est le câble d'alimentation qui est considéré comme le moyen de se déconnecter du CA. La prise à laquelle le système est branché doit se situer à proximité de l'équipement et être facilement accessible.
Le microprocesseur et le dissipateur de chaleur peuvent être chauds si le système a été sous tension. Faites également attention aux broches aiguës des cartes et aux bords tranchants du capot. Nous vous recommandons l'usage de gants de protection. Español Lea todas las declaraciones de seguridad y precaucion de este documento antes de realizar cualquiera de las instrucciones. Vea Intel® Server Boards and Server Chassis Safety Information en el CD Resource y/o en http://www.intel.
Para obtener un enfriamiento y un flujo de aire adecuados, reinstale siempre las tapas del chasis antes de poner en marcha el sistema. Si pone en funcionamiento el sistema sin las tapas bien colocadas puede dañar los componentes del sistema. Para instalar las tapas: 1. Asegúrese primero de no haber dejado herramientas o componentes sueltos dentro del sistema. 2. Compruebe que los cables, las placas adicionales y otros componentes se hayan instalado correctamente. 3.
PASSI DI SICUREZZA: Qualora si rimuovano le coperture del telaio per accedere all'interno del sistema, seguire i seguenti passi: 1. Spegnere tutti i dispositivi periferici collegati al sistema. 2. Spegnere il sistema, usando il pulsante spento/acceso dell'interruttore del sistema. 3. Togliere tutte le spine dei cavi del sistema dalle prese elettriche. 4. Identificare e sconnettere tutti i cavi attaccati ai collegamenti I/O od alle prese installate sul retro del sistema. 5.
