I would think so, but someone more experienced in the Lustre o2ib LND
and iWarp should chime in on that -- I've never used iWarp, only IB.

I don't expect that to work, unless the Voltaire is converting iWarp to
IB -- and I highly doubt that. It is more likely using EoIB to transport
the ethernet frames over the IB fabric. You will likely need a Lustre
router to sit between the two fabrics.
