If you have a preference for Free Software, GlusterFS would work, unless you have many millions of small files. It would also depend on your available hardware, as there is not a 1-to-1 correspondence between a typical GPFS setup and a typical GlusterFS setup. But at least it is free and easy to try out. The mailing list is active, the software is now mature ( I last used GlusterFS a few years ago) and you can buy support from Red Hat if you like.<br><br>Take a look at the RH whitepapers about typical GlusterFS architecture.<br><br>CephFS, on the other hand, is not yet mature enough, IMHO.<br><div class="gmail_quote"><div dir="ltr">On Mon, Feb 13, 2017 at 8:31 AM Justin Y.
