-raid
0, 1, 5, 6, 10, 50,
60
Sets the RAID type or level for the
virtual disk.
NOTE: If this option is not specified for
any RAID controller, RAID 0 is taken as
the default.
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.
6 — RAID 6 is an extension of RAID 5
and uses an additional parity block.
It uses block-level striping with two
parity blocks distributed across all
member disks. RAID 6 provides
protection against double disk failures
and failures while a single disk is
rebuilding. In case there is only one
array, RAID 6 may be a better option
than a hotspare disk.
10 — RAID 10 is a stripe of mirrors.
Multiple RAID 1 mirrors are created,
and a RAID 0 stripe is created
over these.
