<p class="MsoNormal"><span style="color:#1F497D">Currently
jlabsite and jlabapps are actually aliases that point to the
same NetApp, cfs1a.jlab.org.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">We are moving
these areas to new virtual filers on new NetApp hardware.
The IP addresses that both of these resolve to now, will

maps for many years.. therefore the number and location of
machines that actually use them is impossible for us to
know.<o:p></o:p></span></p>

many other exports share the same NetApp right now).<o:p></o:p></span></p>
