The logical disks usually belong to one RANK, and a continuous space on one RANK is assigned to
them.
In a multi-RANK configuration, the logical disks belong to multiple RANKs, and continuous spaces on
the multiple RANKs are assigned to them.
Figure 2-5 Logical Configurations of Disk Arrays (RANK)
The table below shows the number of physical disks and the number of RANKs available by the RAID
type on the 100/1000/2000 series (not including S400/S1400/S2400).
