<p>The former. We are curious how to selectively delete data from a
parallel filesystem. For example we commonly use Lustre, ceph,
and Isilon in our environment. That said if other types allow for
easier destruction of selective data we would be interested in
hearing about it.<br>

<div>For the latter, DOE does not allow us to send any
non-volatile media offsite once it has had user data on it.
When we are done with drives, we have a very big shredder.</div>
