You can find Capacity Estimations under the Analytics in the left navigation menu.
You can search for this page or any other by clicking the search button () at the top left of the page or pressing '/' on your keyboard.
The Capacity Estimations page displays a chart showing how capacity usage is distributed among the larger subfolders of a selected Element Store path:
The chart shows up to 1000 folders in total, at three levels.
The folder for which current estimations are being reported is displayed in the top-left corner. Navigate to a higher level directory by clicking on its link in the displayed path.
When you first open the Capacity Estimations page, the selected path points to the root directory of the Element Store.
The circle in the center of the chart represents 100% of the storage usage for all data stored in the selected directory. It displays the amount of capacity used by data stored under the path.
The closest ring to the center represents the distribution of that usage among the direct subfolders of the selected directory. Each folder has its own color.
Click a subfolder to drill down to that subfolder's path.
The outer ring shows how data is distributed inside each subfolder. Subfolders of subfolders are shown in the same color as their parent folder.
Click a folder to drill down to that folder's path.
A blank sector represents the composite proportional allocation of:
Folders under 5 GB in size.
Folders that don't appear due to the limit on the total number of folders that can be shown (1000).
On the right of the page, you can see more details about the usage distribution among the larger subfolders of the selected path:
The selected path.
This section shows estimates for the selected path, except when you hover over a subdirectory on the chart. Then, it shows these estimates for that subdirectory. The estimates include:
Data reduction. An estimate of the data reduction ratio in effect for the data under the selected path (or the subdirectory that you are hovering over)
Usable: The estimated amount of usable capacity being used by the data under the selected path.
This is the amount of data that is attributed to the path after taking data reduction and data block sharing into consideration.
Unique: The amount of unique capacity being used by the data under the selected path.
This is the amount of capacity that you would reclaim if you were to delete the directory.
Logical. The amount of logical capacity being used by the data under the selected path.
This is the amount of data written to the directory.
This indicator shows which type of usage is currently shown in the usage estimations, both on the chart and in the details in the grid. The type can be usable, unique or logical capacity.
The following information is displayed for the selected path and it's composite subfolders:
The directory name
The amount of capacity attributed to the directory, in terms of the selected index.
The percentage of the usage of the selected path that is used by the directory.
A weighted average value calculated from the atime values of the files in the directory, with weighting based on file size. atime is a file attribute that tells you when a file was last accessed.
Toggle Show/Hide small folders to show or hide all of the folders that are less than 5 GB in size.
Drill down: Click a subfolder to drill down to the subfolder's path. The subfolder path becomes the selected path.
Jump to a path: Enter any Element Store path in the Jump to path field to select that path or click a directory name in the breadcrumbs to jump up to a parent directory.
Select a different usage type to use as the index: select one of the following from the Select type dropdown:
Click Copy Path to copy the current selected path to the clipboard.
Hover over any subfolder in the chart to see the estimated usage and DRR for the subfolder.
Click the Refresh data button to refresh the data shown.
