Configuring Your Server 4-23
RAID Levels
The record mode enabling the RAID feature includes several levels. Among the levels, the Onboard
RAID Controller (LSI Embedded MegaRAID) supports RAID levels 0, 1, and 10. The Internal
RAID Controller (N8103-116 equivalent) supports RAID levels 0, 1, 5, 6, 10, and 50. The number
of hard disk drives required to create a disk group varies depending on the RAID level as shown in
the table below.

IMPORTANT:
To use RAID 5, RAID 6, or RAID 50 with Internal
RAID Controller (N8103-116 equivalent), 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 Onboard
RAID Controller (LSI Embedded MegaRAID) or Internal RAID Controller (N8103-116 or
equivalent), creating one disk group (DG).
