Volumes are block storage devices that you attach to instances to enable persistent storage.
As a cloud administrative user, you can manage volumes and volume types for users in various projects. You can create and delete volume types, and you can view and delete volumes.
Cloud users can attach a volume to a running instance or detach a volume and attach it to another instance at any time. For information about how to use the dashboard to create and manage volumes as an end user, see the VMware Integrated OpenStack User Guide.
