Sure, DCB is very useful, in many environments. And maybe even a requirement

least as useful as standard IB in many cases

lossless traffic can be achieved today using global pause, for
example.
Liran, I would say that OTOH global pause isn't the way to go and OTHO
IB RC functions quite bad when many packets are lost. As such RDMAoE
without PFC and mapping priorities into TCs (the Ethernet VLs) isn't
really for production, for any non trivial environment involving more

I agree that implementing DCB is important for IBoE, but why do you say
that a classical ethernet fabric with global pause isn't usable? That
should be roughly equivalent to an IB fabric that uses only a single VL,
which is the case for many production
