Supported Device Technology The various device technologies supported by the Intel® RAID Controller RS25FB044 are described in the subsections that follow. Support for Hard Disk Drive Devices The Intel® RAID Controller RS25FB044 integrates four internal and four external highperformance SAS/SATA II ports that support SAS and enterprise-class SATA hard drives.
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. One or more physical drives are selected and associated as an array. 2. One or more arrays are associated and given a RAID level. This process creates a virtual drive and provides an option to initialize the virtual drive. 3. The RAID firmware presents the virtual drive to the operating system.
Appendix A: Drive Roaming 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.

Appendix B: 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.
