Ceph yes a little.  Looking forward to it being sufficiently stable to 
use in production.  POHMELFS, not yet.  Looked at it and it looks very 
interesting.  Wasn't sure of current state.

I am dealing with interface blocks right now to have a fortran code call 
a C code correctly.  Ugh...  But I understand your pain.

Building GlusterFS is quite easy, and the stacking is quite logical. 
Only issues we have run into is that sometimes fuse crashes.

I have lots of friends at both places.  Sad situation.  Cray will grow 
and thrive.   SGI has basically evaporated.  Though I am seeing some of 
their technology get open sourced very rapidly.
