<p class="MsoNormal">If I setup a filesystem to have data replication of 2 (2 copies of data), does the data get replicated at the NSD Server or at the client? i.e. Does the client send 2 copies over the network or does the NSD Server get a single copy and
then replicate on storage NSDs?<o:p></o:p></p>
