In order to protect against something like a rack failure, you may have had to use a very high NumberOfFailuresToTolerate value, resulting in multiple copies of the VM data dispersed around the cluster. With VSAN 6.0, this is no longer a concern as hosts participating in the VSAN Cluster can be placed in different failure domains.
