The Capacity page in the VAST Web UI enables you to see estimations of how capacity usage is distributed among Element Store paths. The page gives you visibility into the usage breakdown for any given path and estimates the data reduction on the path. It enables you to drill down or jump to another path and see the composition and usage distribution of any requested directory in the Element Store.
The Capacity page can help you to see:
How individual directories are benefiting from data reduction and how much space they are using after data reduction.
How much space will be freed if you delete the files and directories under any given path.
An indication of the average age of data at any given path.
The capacity estimations can be displayed according to logical capacity, usable capacity, or unique capacity. Unique capacity is the amount of capacity that would be freed if a directory were to be deleted.
