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?
