The View Report drop-down menu on the Mission Control Toolbar includes interactive graphical representations of historical and current storage usage across all Delphix Engines you are monitoring.

These include visualizations of Storage Breakdown and Storage History. Storage Breakdown provides different ways of viewing data, including Total to interact with graphs containing the current total storage on all engines and Source to view the breakdown of disk capacity currently used for dSource data. Storage History provides a graphical interface to analyze all historical storage data collected by monitored engines in the past 30 days.

The following activities provide more detail for how to interact with the graphs.

Activity Nine: Viewing Storage Breakdown Reports

Selecting Storage Breakdown allows you to analyze current storage usage by Total and Source. 

Working with Total Storage Graphs

Clicking the Total button presents an interactive data visualization of total storage on each Delphix Engine. The bar graphs show the breakdown of all disk capacity between:
  • Source – The capacity used for dSource data

  • Virtual – The capacity used for VDBs

  • Free space – The amount of available free space on the engine

The Category Legend Key on the right-hand side, shown in the screenshot below, helps you see how your current storage is distributed.

Graphical Visualization of Storage Capacity Breakdown for All Delphix Engines


To display engines according to a particular category:

  1. Click a category in the Category Legend Key.

The engines will appear in order according to the category you chose to prioritize. In the screenshot above, Total has been prioritized.

Using the information displayed with the Total button, you can:

  • Determine which engines have the most free space and identify good candidates for new dSources/VDBs

  • Determine which engines have the least free space, identify which engines need additional storage or require storage to be freed, and identify which engines may require different retention policies

  • Determine which engines have the most space used by VDBs and take actions such as refreshing VDBs or removing unneeded VDBs and/or VDB snapshots

  • Determine which engines have the most space used by dSources and identify source breakdown to see how capacity is used for dSource data. If needed, you can make appropriate changes to free up space.

Working with Source Usage Graphs

Selecting the Source button presents an interactive data visualization from a source perspective. The bar graphs show how much of each engine’s storage space is used by:
  • Active Source Data – The capacity used for current active copy of dSources

  • Manually Retained Snapshots – The capacity held exclusively due to manually retained snapshots

  • Snapshot Retention – The capacity held due to snapshot retention policy, either exclusively or in combination with manual settings

  • Snapshots for Dependent VDBs – The capacity of snapshots held due to VDBs that have been provisioned from them, either exclusively or in combination with policy or manual settings

  • Log Retention – The capacity held due to LogSync retention policy.

The Category Legend Key on the right-hand side helps you see how your current storage is distributed.

Graphical Visualization of Storage Capacity Breakdown for All Engines by Source

To display engines according to a particular category:

  1. Click a category in the Category Legend Key.

The engines will appear in order according to the category you chose to prioritize. In the screenshot above, Active Source Data has been prioritized.

Using the information displayed with the Source button, you can determine which engines have the most space used for logs and snapshots and modify retention policies or refresh VDBs to release old snapshots.

Activity Ten: Viewing Storage History Reports

Clicking the Storage History Report visually summarizes total storage usage of all monitored engines for the past 30 days. In this tab, a line graph appears with the historical storage data for the selected Delphix Engine(s) and a drop-down list of Delphix Engines from which to choose, as seen in the screenshot below.

Storage History for Top Five Engines

By default, the above graph shows historical details of the top five engines, based on the most recent data point. However, you can choose which engines’ details to display by selecting it from the drop-down menu.

The screenshot below illustrates using the scroll bar at the bottom to hone in on a particular time and date of capacity use. Use your mouse and hover over interesting points on the graph for specific storage information. A rollover box will appear with specific information.
