<font size=3 face="Arial">As I think you understand we can only provide
general guidance as regards your questions. If you want a detailed
examination of your requirements and a proposal for a solution you will
need to engage the appropriate IBM services team.</font><br><br><font size=3 face="Arial">My personal recommendation is to use as few
file systems as possible, preferably just one. The reason is that
makes general administration, and storage management, easier. If
you do use filesets I suggest you use independent filesets because they
offer more administrative control than dependent filesets. As for
the number of nodes in the cluster that depends on your requirements for
performance and availability. If you do have only 2 then you will
need a tiebreaker disk to resolve quorum issues should the network between
the nodes have problems. If you intend to continue to use HSM I would
suggest you use the GPFS policy engine to drive the migrations because
it should be more efficient than using HSM directly.</font><br><br><font size=2 face="sans-serif">Regards, The Spectrum Scale (GPFS) team<br><br>------------------------------------------------------------------------------------------------------------------<br>If you feel that your question can benefit other users of Spectrum

I will recall all data and copy it to new<br>infrastructure.
