    <para>Volumes are block storage devices that you attach to
        instances to enable persistent storage. You can attach a
        volume to a running instance or detach a volume and attach it
        to another instance at any time. You can also create a
        snapshot from or delete a volume. Only administrative users
        can create volume types. </para>
