I understand that some people are using QDR right now. If you are, could you please share your experiences with QDR. What HCA, what kinds of problems, etc. Has anyone tried IB bonding with QDR?

What HCA, what kinds of problems, etc.Yes, there are quite a few sites which have implemented a QDR IB fabric around the world. The majority (in my experience) are using Mellanox ConnectX-based HCA''s.

My questions are for QDR and IB-Bonding with Lustre.None of this is really QDR-specific, but have a look at : https://bugzilla.lustre.org/show_bug.cgi?id=20153 and https://bugzilla.lustre.org/show_bug.cgi?id=21861 ... and note that ib-bonding doesn''t provide load balancing, active/failover mode only -frank> > Roger Spellman > Staff Engineer > Terascala, Inc. > 508-588-1501 > www.terascala.com <http://www.terascala.com/> >

I think what Jason meant is that he is not authorized to view it. Neither am I. Could the permissions be changed, so that we could view that bug?
