<p class="MsoNormal">So I have an ESS today and it’s nearing end of life (just our own timeline/depreciation etc) and I will be purchasing a new ESS. I’m working through the logistics of this. Here is my thinking so far:<o:p></o:p></p>
<p class="MsoNormal">This is just a big Data Lake and not an HPC environment<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Option A<o:p></o:p></p>
<p class="MsoNormal">Purchase new ESS and set it up as a new cluster<o:p></o:p></p>
<p class="MsoNormal">Remote mount old cluster and copy data (rsync or AFM)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Option B<o:p></o:p></p>
<p class="MsoNormal">Purchase new ESS and set it up to join the old cluster same filesystems<o:p></o:p></p>
<p class="MsoNormal">Evacuate old NSDs and expel Old nodes<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Option C<o:p></o:p></p>
<p class="MsoNormal">Purchase new ESS and set it up as a new cluster<o:p></o:p></p>
<p class="MsoNormal">Point all new data to new cluster and age out old cluster over time (leverage TCT or Archive)<o:p></o:p></p>
