RAID 5 Logical Drive

24 drives, 1 redundancy drive

Configuration A - One logical drive with all 24 drives

As illustrated above, Configuration A is a RAID 5 logical drive consisting of 24 physical drives. Configuration B is a logical volume made of four RAID 5 logical drives.

Figure 1 - 17 Logical Volume with 4 Logical Drives

Configuration B can help to reduce the chance of encountering points of failure:

a)Higher Redundancy: Configuration A has one dedicated spare, while Configuration B allows the configuration of four spares. In Configuration B, the risk of simultaneous drive failure in a logical drive is significantly reduced than in Configuration A. The total array capacity is comparatively smaller by the use of spares.

b)Less Rebuild Time: The time during rebuild is a time of hazard. For example, a RAID 5 logical drive can only withstand single drive failure, if another drive fails during the rebuild process, data will be lost. The time span for rebuilding a faulty drive should be
