RAID Levels
The record mode enabling the RAID feature includes several levels. Among the levels, the on-board RAID (MegaRAID
ROMB) supports the following levels; RAID 0, RAID 1, RAID 5, RAID 6, RAID10, and RAID 50. 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 install the optional RAID Upgrade Kit.
To configure RAID6 using Express Setup, at least four hard disk drives of same
capacity must be installed.
NOTE:
For more information on the RAID levels, see "RAID Levels" described later in
this chapter.
Disk Group
A disk group is configured with several HDDs (at least two).
The authorized 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
(MegaRAID ROMB), creating one disk group (DG).
HDD 1
(36 GB)
HDD 2
(36 GB)
HDD 3
