RAID 3

Striping with parity on the dedicated disk. RAID 3 allows one
hard drive fails or plugs out.

RAID 5

Striping with interspersed parity over the member disks. RAID
5 allows one hard drive fails or plugs out.

RAID 6

2-dimensional parity protection over the member disks. RAID
6 allows two hard drives fail or plug out. If it needs to rebuild
two hard drives at the same time, it will rebuild the first one,
then the other, by sequence.

RAID 0+1

Mirroring of the member RAID 0 volumes. RAID 0+1 allows
two hard drives fail or plug out, but at the same array.

RAID 10

Striping over the member RAID 1 volumes. RAID 10 allows
two hard drives fail or plug out, but at the different array.

RAID 30

Striping over the member RAID 3 volumes. RAID 30 allows
two hard drives fail or plug out, but at the different array.

RAID 50

Striping over the member RAID 5 volumes. RAID 50 allows
two hard drives fail or plug out, but at the different array.

RAID 60

Striping over the member RAID 6 volumes. RAID 40 allows
four hard drives fail or plug out, but each two at the different
array.

JBOD

The abbreviation of

“J

ust a

unch

isks

”

. No protection.

VG will fail if any hard drive fails or plugs out.

4.2 VG migration and expansion

To migrate the RAID level, please follow the procedures. If migrate to the same
RAID level of the original VG, it is called expansion.

1. Select

“/ Volume config / Volume group”

2. Decide which VG to be migrated, click the blue square button “

” in

the RAID column next the RAID level.

3. Change the RAID level by clicking the down arrow mark “

”.

There will be a pup-up shows if the HDD is not enough to support the
new setting RAID level, click “

” to increase hard drives,

then click “

“ to go back to setup page.
