3.7.0 HP StorageWorks HP Scalable NAS File Serving Software provisioning guide for Oracle HP Scalable NAS (AG513-96013, October 2009)

Taking this example one step further, greater scalability can be achieved. Because
each of the Virtual NFS Services can export the same filesystem, the same datafile
can be hosted by different members of the HP Scalable NAS cluster at the same time
(see Figure 12). All this happens, even though the Oracle server thinks it is connected
to the same NAS server via four separate paths. The administrator can transition
from one NAS head serving to many without the database having to shutdown.
