RAID Features

Strip size is specified when you create a RAID volume. Strip size options for RAID levels 0, 1, 5, 
and 10 are specified below. 

5.2.9.2

RAID Level 0 Example

Data on a RAID 0 volume is striped across all of its member disks. The strip size is the amount of 
logically contiguous data striped on each disk. Since data is spread across several physical disks, 
accesses tend to be evenly distributed across all the disks. This sharing of the workload increases 
the throughput when compared to a single physical disk. There is neither parity nor mirroring, so a 
RAID 0 volume will lose data if one of its member disks fails. 

Figure 5-3. Data Map of a RAID Level 0 Volume with 4 Disks, Showing the First 5 Stripes

5.2.9.3

RAID Level 1 Example

A RAID 1 volume mirrors the same data on two of its members. This type of array gives good 
performance and high reliability but its usable capacity is one half of its physical capacity. See 

Figure 5-4

. In a two disk RAID 1 volume, each disk has an identical copy of the data. In the event 

a disk fails, data integrity is maintained.
