Filesystems are getting better, but they are still (all of them) quite 
temperamental and may not necessarily work will with your applications. 
  At my old site, we brought in any vendor willing to let us test their 
stuff.

We got burned on another solution earlier in the contract.  It passed 
acceptance, but it still didn't work.  I have become much more diligent 
at "breaking" filesystems.  It has help understand what filesystems can
and cannot do.
