The Data Sources window enables you to view, edit, and delete existing data sources, create new data sources, and acquire a data source. You can access this window by selecting Settings, and under Setup click Data Sources.
A data source is a read-only data structure that contains information about where the data in a specific database originates from. Data sources must be defined before environments can be polled. For example, a data source can be either an OnCommand Unified Manager database that contains information about a storage environment or a VMware database with information about a data center.

Data Sources table
The Data Sources table lists the existing data sources. You can customize the table display by using the filtering and sorting features available for each column, as well as by rearranging the column order.
-

Clicking the column header toggles between ascending and descending order of sorting. You can identify the applied sort order by the sort arrows (
for ascending and 
for descending). -
To rearrange the location of columns, you can drag and drop columns to place them in any required order. However, you cannot hide or delete any of these columns.
