With a RAID 1, RAID 5, or RAID 6 volume, you can also add a spare disk after the
RAID is created.
See Chapter 6: Tips and Tricks > Adding a Spare Disk for details.
For more information on RAID, see Appendix B: RAID Basics.
RAID Level
You can set the storage volume as JBOD, RAID 0, RAID 1, RAID 5, RAID 6 or
RAID 10. RAID configuration is usually required only when you first set up the
device. A brief description of each RAID setting follows:
RAID Levels
Level Description
JBOD The storage volume is a single HDD with no RAID support. JBOD
requires a minimum of 1 disk.
RAID 0 Provides data striping but no redundancy. Improves performance
but not data safety. RAID 0 requires a minimum of 2 disks.
RAID 1 Offers disk mirroring. Provides twice the read rate of single disks,
but same write rate. RAID 1 requires a minimum of 2 disks.
RAID 5 Data striping and stripe error correction information provided.
RAID 5 requires a minimum of 3 disks. RAID 5 can sustain one
failed disk.
RAID 6 Two independent parity computations must be used in order to
provide protection against double disk failure. Two different
algorithms are employed to achieve this purpose. RAID 6 requires
a minimum of 4 disks. RAID 6 can sustain two failed disks.
RAID 10 RAID 10 has high reliability and high performance. RAID 10 is
implemented as a striped array whose segments are RAID 1
arrays. It has the fault tolerance of RAID 1 and the performance of
RAID 0. RAID 10 requires 4 disks. RAID 10 can sustain two failed
disks.
WARNING
If the administrator improperly removes a hard disk that should not be
removed when RAID status is degraded, all data will be lost.
NOTE
Building a RAID volume may take time, depending on the size of hard drives
and RAID mode. In general, while the RAID volume building process is up to
“RAID Building” then the data volume is capable to be accessed.
WARNING
Creating RAID destroys all data in the current RAID volume. The data is
unrecoverable.
