glusterfs vs. gpfs?

[Sascha Ottolski <ottolski@xxxxxx>]

Hi,

I just stumbled over gpfs 
(http://en.wikipedia.org/wiki/General_Parallel_File_System), which 
seems to be a commercial, closed source product by IBM. I'm wondering 
if anyone around has some experiences with, especially about in terms 
of how it compares to glusterfs?


Thanks,

Sascha
