A hashing algorithm is used to work out what rows go in what fragment.

A fragment is a horizontal partition of the table.

Fragments can be stored in more than one place.

The number of DB nodes can be other than 2**N, but the data may not be as balanced as you can not (yet - scheduled for 5.1) set a custom hash function.
