NOTE: See the safety and caution statements in your Product Information Guide that came with your Dell™ PowerEdge™ system or Dell Precision™ workstation. SAFETY: General • Observe and follow service markings.
YD912bk1.book Page 8 Monday, April 2, 2007 4:39 PM In addition, take note of these safety guidelines when appropriate: • 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 disconnecting the cable. As you pull connectors apart, keep them evenly aligned to avoid bending any connector pins.
YD912bk1.book Page 9 Monday, April 2, 2007 4:39 PM Overview The Dell™ Serial-Attached SCSI (SAS) 5/iR controller is Dell’s next generation of controller with integrated redundant array of independent disks (RAID) capabilities. SAS technology is not backward compatible with the previous generation of SCSI devices. The SAS 5/iR Adapter is a half-length, standard-height PCI-E card, while the SAS 5/iR Integrated is embedded in the platform hardware.
YD912bk1.book Page 10 Monday, April 2, 2007 4:39 PM About RAID RAID is a group of multiple independent physical disks that provide high performance by increasing the number of drives used for saving and accessing data. A RAID disk subsystem improves I/O performance and data availability. The physical disk group appears to the host system as a single storage unit or as multiple logical units. Data throughput improves because multiple disks can be accessed simultaneously.
YD912bk1.book Page 11 Monday, April 2, 2007 4:39 PM Integrated Mirroring With Integrated Mirroring (RAID 1), data written to one disk is simultaneously written to another disk. If one disk fails, the contents of the other disk can be used to run the system and rebuild the failed physical disk. The primary advantage of Integrated Mirroring is that it provides 100 percent data redundancy. Because the contents of the disk are completely written to a second disk, it does not matter if one of the disks fails.
