- Storage Distribution Algorithm -
Each volume (LUN) is spread across all drives
Data is âcutâ into 1MB âpartitionsâ and stored on the disks
XIV algorithm automatically distributes partitions across all disks in the
system pseudo-randomly

Data distribution only changes when the system changes
Equilibrium is kept when new hardware is added
Equilibrium is kept when old hardware is removed
Equilibrium is kept after a hardware failure
