I think you need to start to list your requirements in a coherent manner 
first, in terms of performance, features, and redundancy. The solution 
you should be looking for will be more obvious then.

Hmm, personally I find that sticking with only what ships with the 
distro to be too limiting as soon as you need to cover a use-case that 
isn't very basic and boring. But if you are looking for a "supported" 
solution, Gluster Inc. do have support contracts available.

But without more information on your use-case and expected access 
patterns, it is impossible to suggest a solution in a particularly 
meaningful way.
