- 40GB Ethernet: A Competitive Alternative to Infiniband (LAMMPS, WRF, Quantum ESPRESSO Modelling with 40GB iWARP Technology (pdf)
Chelsio published benchmark results comparing NIC and RDMA performance for Windows 2012-R2 SMB-Direct. RDMA provides a large performance and efficiency boost to SMB, and T5 is the ideal plug-and-play provider.
Chelsio published a benchmark on NFS/RDMA performance comparing IB-FDR and iWARP, again showing the two at performance parity. There is no longer need to compromise on performance or features when choosing Ethernet.
