RAID Management

The subsystem can implement several different levels of RAID technology.

RAID levels supported by the subsystem are shown below.

RAID
Level

Description

Min
Drives

0 + 1

Block striping is provide, which yields higher performance than with

individual drives. There is no redundancy.

Drives are paired and mirrored. All data is 100% duplicated on an

equivalent drive. Fully redundant.

Data is striped across several physical drives. Parity protection is

used for data redundancy.

Data is striped across several physical drives. Parity protection is

used for data redundancy.

Data is striped across several physical drives. Parity protection is

used for data redundancy. Requires N+2 drives to implement

because of two-dimensional parity scheme

Combination of RAID levels 0 and 1. This level provides striping

and redundancy through mirroring.
