[gpfsug-discuss] GPFS + RDMA + Ethernet (RoCE/iWARP)

[Jez Tucker]

Hello all

  I've been having a pootle around ye olde Internet in a coffee break and noticed that RDMA over Ethernet exists.

http://en.wikipedia.org/wiki/RDMA_over_Converged_Ethernet
http://www.hpcwire.com/hpcwire/2010-04-22/roce_an_ethernet-infiniband_love_story.html

Has anyone had any experience of using this?  (even outside GPFS)

I know GPFS supports RDMA with Infiniband, but unsure as to RoCE / iWARP support.
It suddenly occurred to me that I have 10Gb Brocade VDX switches with DCB & PFC and making things go faster is great.

Perhaps the HPC crowd do this, but only via IB?

Thoughts?
