0, 1, 5, 10, 50 Sets the RAID type or level for the virtual disk.
The valid arguments are:
0 — RAID 0 uses data striping, which is writing data in
equal-sized segments across the array disks. RAID 0
does not provide data redundancy.
1 — RAID 1 is the simplest form of maintaining
redundant data. In RAID 1, data is mirrored or
duplicated on one or more drives.
5 — RAID 5 provides data redundancy by using data
striping in combination with parity information.
Rather than dedicating a drive to parity, the parity
information is striped across all disks in the array.
10 — RAID 10 is a stripe of mirrors. Multiple RAID 1
mirrors are created, and a RAID 0 stripe is created
over these.
50 — RAID 50 is a dual level array that uses multiple
RAID 5 sets in a single array. a single hard drive failure
can occur in each of the RAID 5 without any loss of
data on the entire array. Although the RAID 50 has
increased write performance, when a hard drive fails
and reconstruction takes place, performance decreases,
data/program access is slower, and transfer speeds on
the array are affected.
NOTE: If this option is not specified for any RAID
controller, RAID 0 is taken as the default.
