Hi friends.<br>
<br>
I'm evaluating different DFS to increase our infrastructure from 10
nodes to 40 nodes approximately. One of the bottleneck is the shared
storage installed to enable the live-migration.<br>
Well, the selected candidate are NFS, Ceph or Lustre (which is
already installed for HPC purpose). <br>
<br>
Creating a brief planning and avoiding network connectivities:<br>
<br>
<b>a)</b> with NFS and Ceph, I think it is possible but dividing the
whole infrastructure (40 nodes) in smaller clusters, for instance;
10 nodes with 1 storage each one. Obviously, the live-migration is
only possible between nodes on the same cluster (or zone)<br>
<br>
<b>b) </b>with Lustre, my idea is to connect all the nodes (40
nodes) to the same lustre (MDS) and use all the concurrency
advantages of the storage. In this case, the live migration could
be possible among all the nodes.<br>
<br>
I would like to ask you for any idea, comment or experience. I think
the most untested case is b), but has anyone tried to use Lustre in
a similar scenario? Any comment in any case a) o b) are appreciated.<br>
<br>
Thanks<br>
Miguel.<br>
