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
Block striping is provided, which yields higher
performance than with individual drives. There is
no redundancy.
1
1
Drives are paired and mirrored. All data is 100%
duplicated on an equivalent drive. Fully
redundant.
2
5
Data is striped across several physical drives.
Parity protection is used for data redundancy.
3
6
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.
4
10
Combination of RAID levels 1 and 0. This level
provides redundancy through mirroring and
striping. RAID 10 requires the use of an even
number of disk drives to achieve data protection.
4
50
RAID 50 provides the features of both RAID 0
and RAID 5. RAID 50 includes both parity and
disk striping across multiple drives. RAID 50 is
best implemented on two RAID 5 disk arrays
with data striped across both disk arrays.
