Regarding GlusterFS, I suggest take a look on this website:
http://www.jamescoyle.net/

There's a lot of materials to work on this site...

In one of the articles, James said that if GlusterFS was combined with ZFS,
then performance is not the bottleneck...

Some experience here can support this statement?
