One suggestion is to try to use the pNFS for Lustre. I can send you the patches or you can get them from Lustre tree. Let me know if this will be good for you. We are already using it to test Linux file client as well as Windows. Whamcloud demo it during SC11 and demo wire speed. What I would also suggest is for you maybe to come to the Connectathon in February and test the client against the other servers that you cannot have as they are not products but prototypes. > > If others have suggestions on how I might gain access to pNFS servers > for testing, I would appreciate hearing.

The next BAT is at CITI so maybe you bring a client prototype there. /Sorin > > rick > > ----- Original Message ----- >> On Thu, 08 Dec 2011 19:40:19 -0500, Sorin Faibish >> wrote: >> >> > Attached please find the slides that we presented yesterday at >> > USENIX >> > LISA 11 >> > conference in Boston.
