Details
Data is automatically redistributed evenly across all disks in the cluster when a disk is either added or removed.

Data migrations are performed in a many-to-many fashion.

There is no user-intervention required for any the redistribution activities.

Data Rebalancing can be throttled by changing the priority policy. The default policy for rebalance: Favor Application I/O. Alternative policies are: No Limit, Limit Concurrent I/O, Dynamic Bandwidth Throttling.
