Figure 1 - 16 Logical Drive Composed of 24 Drives

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
