Enable VAAI for fast provisioning to allow offloading of clone operations to compatible NAS arrays.


In-place consolidation of a fast-provisioned VM is not supported on storage containers that employ native snapshots. VVOLs and VAAI-enabled datastores use native snapshots, so fast-provisioned VMs deployed to one of these storage containers cannot be consolidated. If you need to consolidate a fast-provisioned VM deployed to a VVOL or VAAI-enabled datastore, you must relocate it to a different storage container.


  1. Click the Manage & Monitor tab and click Datastores in the left pane.
  2. Right-click the datastore name and select Properties.
  3. On the General tab, select Enable VAAI for fast provisioning.
  4. Click OK.
