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 RAID
Controller (MegaRAID), creating one disk group (DG).
NOTE:
For details of the RAID levels, refer to "RAID Levels" described
