We are seeing generally very good results with GlusterFS.  Performance 
is in part in how you arrange your translators, how your fabric is 
connected, etc.  If you don't work hard with it, you can get ~200 MB/s 
per client over SDR IB.  If you work a bit harder you can get ~500 MB/s 
per client.  You do need enough server bandwidth to be able to source 
the data.

I think I had sent a note in the past offering some assistance with 
this.  My bad if the note didn't get through ... or if my responses were 
lost in the shuffle.
