Estimating Disk Space Usage
The disk space required to store a model version in a database depends on the size of the model contents and the size of both computed and other data associated with the model. For a file version, it depends on the size of the binary or text data of the individual file resources.
Model Manager enables you to estimate the disk space usage for various sets of versions including, but not limited to:
•
A selection of versions in a window.
•
All versions belonging to a selection of items in a window.
•
All versions matching a search in the Model Manager window, independent of if all versions are currently shown in the table or if there are more results to retrieve via Show More ().
•
All versions currently targeted in the Maintenance window.
With Latest Versions for Location () selected in the Model Manager window, click Disk Space Usage () in the Statistics section on the Database toolbar and select Version Selection () to open The Estimated Disk Space Usage Dialog Box for the current selection. This will compute the disk space usage of the latest versions of items for the searched location. To compute the disk space usage of all versions belonging to the same items as the selected versions, select Item Selection () in the Disk Space Usage menu ().
With All Versions in Database () selected in the Model Manager window, you can also select Search Result () in the Disk Space Usage menu (). This will compute the disk space usage of all versions that are matched by the current search term and applied search filters.
As a special case for the Search Result () option, you can leave out any search term and search filters in the Model Manager window to obtain the disk space usage of all versions in the database.
Estimating Disk Space Usage as a Maintenance Operation
The Estimated Disk Space Usage Dialog Box
The Estimated Disk Space Usage dialog box — opened, for example, via the Disk Space Usage menu () on the Database toolbar — contains an estimate of the total disk space usage of a set of model and file versions. A textual description of the set of versions is shown under Selection type. Under Disk space, you will find:
•
Versions — the number of versions included in the estimate.
•
Data — the disk space usage of the versions in bytes.
•
Computed data — the disk space usage of all Built, Computed, and Plotted Data of the versions in bytes.
A variant of the dialog box is shown when estimating the disk space usage of all versions of items via the Item Selection option () in the Disk Space Usage menu (). As a convenience, all versions of the items’ drafts are automatically included in the estimate: Under Disk space - total, you will find the total disk space usage of both the items and all drafts created from those items. Under Disk space - drafts, you will find the disk space usage of only the drafts.
Summing the estimated disk space usage numbers obtained for different sets of versions may result in an overestimate as identical data used by different versions is never duplicated in the database, but will still be included in the usage estimate for each set.
