You can configure low disk space thresholds on a storage container to receive an email from VMware Cloud Director when the datastore reaches a specific threshold of available capacity. These warnings alert you to a low disk situation before it becomes a problem.


  1. From the top navigation bar, select Resources and click Cloud Resources.
  2. In the left panel, select Provider VDCs, and click the name of the target provider virtual data center.
  3. Select the Storage Containers tab.
  4. Click the name of a storage container and click Edit.
  5. Select the disk space thresholds for the storage container.

    You can set two thresholds, yellow and red. When you set thresholds on a stand-alone datastore, they apply only to that datastore. If you set thresholds on a datastore cluster, they apply to all datastores in the cluster. By default, VMware Cloud Director sets the red threshold to 15% and the yellow threshold to 25% of the stand-alone datastore or the datastore cluster's total capacity.

    Because the default thresholds on a datastore cluster are based on the total cluster capacity, the thresholds might exceed the capacity of individual datastores within the cluster. When setting thresholds on a datastore cluster, consider the capacity of each datastore in the cluster and set thresholds manually rather than accepting the default threshold configurations.

  6. Click Save.


VMware Cloud Director sets the thresholds for all provider virtual data centers that use the datastore. VMware Cloud Director sends an email alert when the datastore crosses the threshold. When a datastore reaches its red threshold, the virtual machine placement engine stops placing new virtual machines on the datastore except for already-placed imported VMs.
