Table D-1 shows RAID configurations recommended if you want to get logical disks to have the same
capacity when using DataReplication.

*1: Can be specified through both Batch Setting and Individual Setting.
*2: Can be specified through only Individual Setting.
[How to read the table]
The table shows RAID configurations in which RV having the same capacity as for MV can be
bound. The symbols in the table are as follows:
: RV can be bound.
−:
RV (= a logical disk having the same capacity as for MV) may not be bound if the RAID
configurations of RV and MV are different.
[Supplementary information]
If operating logical disks in a configuration other than the above, bind the logical disks in
combination of RAIDs in which RV can be bound. Refer to D.3 "Capacity Except Recommended
RAID Configuration" for details.
