RAID Conversion
Existing arrays can be converted to a different RAID level of equal or greater capacity to add flexibility, redundancy or
for tuning an array for a different storage application. The Storage System supports the following conversions:
From
To
Comments
RAID 30
Retains the s ame capacity but allows parity to be written
to separate drives.
RAID 5
Some reduction in performance, lower disk overhead.
RAID 3
Some reduction in performance, lower disk overhead.
RAID 0+1
Full redundancy instead of parity. 8 drives required.
RAID 50
RAID 0
Increases capacity and performance but loses data
redundancy.
RAID 50
Retains the same capacity but stripes parity all drives.
RAID 5
Some reduction in performance, lower disk overhead.
RAID 3
Some reduction in performance, lower disk overhead.
RAID 0+1
Full redundancy instead of parity. 8 drives required.
RAID 30
RAID 0
Increases capacity and performance but loses data
redundancy.
RAID 50
RAID 30
Increases performance. 6 or 8 drives required.
RAID 3
Retains the same capacity but allows parity to be written
to only one drive.
RAID 0+1
Full redundancy instead of parity. 4, 6 or 8 drives
required.
RAID 5
RAID 0
Increases the capacity and performance but loses the
data redundancy.
RAID 50
RAID 30
Increases performance. 6 or 8 drives required.
RAID 5
Retains the same capacity but stripes parity all drives.
RAID 0+1
Full redundancy instead of parity. 4, 6 or 8 drives
required.
RAID 3
RAID 0
Increases capacity and performance but loses data
redundancy.
