(3-3) Supported RAID
The RAID levels D8-3010 supports are as follows:
However, SATA disk drive supports only RAID-5,50, 6 and TM
Besides, RAID can configure only in the same Disk Director (basic Disk Director: 16DE, 192HDD,
Expansion Disk Director: 16DE, 192HDD) of a node.

*1: Can dynamically change LUN capacity by dynamic pool function.
*2: Only SAS disk can be used for Dynamic pool with RAID-1.
*3: Capacity efficiency is constant, regardless of the number of configured drive. Even in
case of adding a disk drive, the capacity efficiency does not change.
The theoretical capacities of dynamic pool are slightly smaller than the above figures.
