RAID Levels
The record mode enabling the RAID feature includes several levels. Among the levels, the Internal
RAID Controller (equivalent to N8103-116) supports the following levels; RAID 0, RAID 1, RAID
5, and RAID 6. The number of HDDs required to create a disk group varies depending on the RAID
level as shown in the table below.

IMPORTANT:
To use RAID 5 or RAID 6, you need to additionally
install the optional N8103-119 RAID Upgrade Kit.
NOTE:
For details of the RAID levels, see "RAID Levels" described
later in this chapter.
Disk Group
A disk group is configured with more than one HDDs.
The allowable number of disk groups is equal to the number of HDDs.
The figure below shows a sample configuration. The three HDDs are connected to the Internal
RAID Controller (equivalent to N8103-116), creating one disk group (DG).
