This feature equalizes data of disk array
subsystems by always synchronizing
their data asynchronously.
The Dynamic Provisioning is a function to
improve the capacity efficiency of disk
drives by assigning physical capacity On
Demand at the time of the Write
command receipt without assigning the
physical capacity to logical units.
