I'm really hoping for something like a pfSense distro that wraps gluster 
up in a nice web GUI.  It'd be great to have an appliance-like OS that 
just works out of the box with a couple clicks.  But that takes time, I 
understand, ... and I'll be patient :-)

Meanwhile, I'm gonna keep working with Gluster and see if I can get the 
performance.  Recently I converted to using Linux Raid 10 on 4 1TB 
drives and now I'm getting 310 MB/s write speed to my brick using "dd" 
test.  That's looking better and getting closer to maxing out a 1GbE 
link.  I need to put gluster on top of this and see if I can continue 
the throughput all the way to the client mount.

As another test, I'm planning to buy some 480 GB SSD drives which can do 
300+ MB/s each.  I'm thinking if I build a Raid 10 configuration with 
those, I might be able to push upwards of 1000+ MB/s.  Then, let Gluster 
and/or Samba sit on top of that and we'll see what's what.
