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 number of
hard disk drives required to create a disk group varies depending on the RAID level as shown in the
table below.
Number of required HDDs

RAID 0 1 4
RAID 1 2 2
RAID 10 4 4
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), creating one disk group (DG).
