NOTE
WARNING
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 >
For more information on RAID, see
RAID Level
You can set the storage volume as JBOD, RAID 0, RAID 1, RAID 5, RAID 6 or
RAID 10, (N8900 support RAID 50 and RAID 60). RAID configuration is usually
required only when you first set up the device. A brief description of each RAID
setting follows:
RAID Levels
Level
JBOD
RAID 0
RAID 1
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.
Creating RAID destroys all data in the current RAID volume. The data is
unrecoverable.
Adding a Spare Disk
Appendix B: RAID
Description
The storage volume is a single HDD with no RAID support. JBOD
requires a minimum of 1 disk.
Provides data striping but no redundancy. Improves performance
but not data safety. RAID 0 requires a minimum of 2 disks.
Offers disk mirroring. Provides twice the read rate of single disks,
but same write rate. RAID 1 requires a minimum of 2 disks.
