Monitor Capacity

When you monitor capacity for a group or a pool, you can see the number of volumes, the data usage (for both volumes and snapshots), the unused reserve, the free space and the size. If you can hover over the total savings, you can see a breakdown of the savings achieved through thin provisioning and data reduction techniques like compression, cloning and deduplication.

When you monitor space for a folder, you can see the total usage of the folder and its distribution into volume usage, snapshot usage and unused reserve. If the folder has a limit, you will see the limit as well as the volume count.

When you monitor space for a volume, you can see the volume usage, unused reserve, free space, and size. It also shows you the space used by snapshots of this volume and the total usage of the volume.

  1. Go to Monitor > Capacity.
    NOTE: In the GUI, information is refreshed automatically every minute. Therefore, the space usage that is reported can be up to one minute out of date.
  2. Select one of the following time intervals:
    • Real time
    • One of the predefined time intervals
    • Custom interval
    1. If you selected Real Time, you can click Pause to stop real-time updates and freeze the data on screen.
    2. Click Resume to continue tracking space usage.
  3. Enter the name of the volume that you want to monitor in the Filter by Volume field.
  4. Select the name of the volume you want to monitor from the popup list.
    When you monitor specific volumes, you can track whether one application uses more or less space than expected. This information can help you decide whether to make schedule modifications for a volume collection to improve efficiency in how the space is used. For example, you may find that you need to take fewer snapshots for a volume, freeing up the space for other applications.
