XIV Showcase
- Storage Distribution Algorithm -
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
Data Module 1 Data Module 2
Data Module 3 Data Module 4
Node 4
