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.

The allowable number of disk groups is equal to the number of HDDs.

RAID Controller (equivalent to N8103-116), creating one disk group (DG).
