Good point Cedric!!
The only thing is that, I would prefer to say "bricks" instead of
"nodes" in your statement.
"starting with 4 bricks (3+1) can only evolve by adding 4 bricks (3+1)"
Oh right, thanks for correcting me !

Also keep in mind that dispersed cluster can only be expanded by the
number of initial nodes, eg starting with 4 nodes 3+1 can only evolve
by adding 4 nodes 3+1, you cannot change the default policy 3+1 to
4+1. So the granularity of the evolution of the cluster is fixed at
the beginning.
