Function: Create new S/W RAID unit
In this function you can create software RAIDs from free (not used) units. If you want to create
RAIDs from used units, you need first to delete content of units in console, be aware this would
ERASE all data from units.
To create a RAID select units, then from ListBox select what type of RAID it will be, then select
desired Chunk size. After setting all demanded parameters press Create button.
Allow to create degraded mode - It allows to create RAID1 with one unit, RAID5 with two
units or RAID6 with three units, even if minimal number of units is not meet.
Chunk size - its a minimal portion of data that is written at a time.
Available RAIDS
- RAID 0: it is stripe array and requires [minimum] 2 units. In RAID 0 you can set the
Chunksize 4k ÷ 256k. The destination size of the RAID Array will be the sum of each drive size
in array.
