Best practice Storage Capacity view provides capacity information about all the storage systems, storage pools, volumes, hosts, filers and shares present in your environment. It allows to easily recognize possible oversubscription risks and impeding saturations within storage pools and identify un-mapped volumes to reclaim unused storage capacity. It also allows storage admins to easily get information related to volumes mapped to hosts to determine the capacity that is actually consumed by each host.
