Overview 15 About RAID R AID is a group of multiple independ ent physical disks that provide high performance or better data availability by increasing the number of drives used for saving and accessing dat a. A R AID disk subsystem improves I/O performance and data availability . The physical disk group appears to the host system as a single stora[...]

16 Overview Figure 2-2. Example of RAID 0 RAID 1 W ith 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 R AID 1 is that it provides 100 percent data r edundancy . Because the conte[...]

Overview 17 RAID 10 R AID 10 requir es two or mor e mirro red sets working together . Multiple R AID 1 sets are combined to form a sing le array . Data is striped across all mirrored drives. Since each drive is mirror ed in R AID 10, no delay is encountered because no parity calculat ion is done. This R AID strategy can tolerate the loss of multipl[...]
