The basic pool is a virtual medium, which manages the space on the pool using a continuous address 
space. 
As you handle logical disks on RANK, assign the continuous space on the pool to the logical disks.   In 
addition, like a multi-RANK configuration, the basic pool supports a striping configuration for 
distributing and storing data into multiple RAID configurations. 
Note that the basic pool does not allow using any additional features such as pool capacity expansion or 
logical disk capacity expansion.

The table below shows the number of physical disks and the number of pools available by the RAID 
type on S400/S1400/S2400/S2800.
