The Storage Capacity screen can be reached via the Capacity item in the Resources menu. This screen shows how storage capacity is allocated for dSources, VDBs, and Snapshots, and permits storage space to be reclaimed through deletion of objects and Snapshots. The Storage Capacity screen displays a maximum of the 20 largest Datasets the top 40 Snapshots. Interaction between the bar graph and grid allows you to instantly see how much storage your selected data is using.
Storage Capacity Screen
The bar graph at the top of the screen displays which dSources and VDBs are the Largest Consumers of storage. Hover over any object to see its name and amount of storage used. Clicking an dataset in the bar graph will open its folder in the Datasets table below, displaying more detailed information.
The Datasets section displays a set of information about each object tracked by the Delphix Engine. Objects can be dSources, VDBs, and the Snapshots taken from dSources and VDBs. Each of these types of objects takes up space. When you select checkboxes in the Datasets table, the total storage space of those items is displayed in the Disk Usage panel on the right.
For each object, the following columns are displayed:
- Name – Name of the object
- Quota – Maximum allocated space or "ceiling"
- Size – Space actually used by the object
% of Total Storage – Percentage occupancy after the selected items are deleted. If 0 items are selected it shows the current percentage of the capacity. If one item is selected it shows what the percent capacity would be if that object were deleted.
Set quota and reservation levels carefully. As a group or VDB approaches the quota value, snapshots may fail, and logs may not be captured, causing LogSync to fail. If an archive log cannot be written to a Snapshot, the Delphix Engine will eventually halt.
When you select checkboxes in the Datasets table, the total storage space of those items is displayed in the Disk Usage panel on the right.
The Disk Usage panel on the right-hand side of the screen shows how much of your total disk capacity is being used by Delphix objects. If you select one or more databases, VDBs, or snapshots in the Datasets table (2), this panel will display how much space those objects are occupying. The Delete button allows you to delete selected items.
The pie chart section visualizes the following elements in relation to one another:
- Disk Capacity – Total capacity of the Delphix Engine
- Disk Usage – Total amount of space used by all the objects
- Selected to Recover – How much storage would be freed if you deleted the items currently selected
To search the Datasets table, enter the name of the object you are looking for. The grid will refresh to display the selected object. You can also sort using the column headings. A lock icon shown next to a snapshot under a dataset indicates that it has a child container provisioned out of it.
Select 
to clear your capacity cache and refresh the page. If you are clearing the cache of a large Delphix Engine, this operation could take several minutes. During this operation, the capacity page is not available.
Select 
to export the information provided in the grid to a.csv file.
Selecting the + icon expands the information about the select item.
