By the end of the getting started series my goal is to get you ready to start coding with a sample program that will demonstrate the performance benefits of RDMA. RDMA always comes with OS bypass (at the data plane) and thus is currently the fastest and lowest-overhead mechanism to communicate data across a network. RDMA is more powerful than RMA/PGAS/one-sided: many RDMA networks such as InfiniBand provide a two-sided message passing interface as well and accelerate transmissions with RDMA techniques ...Up to 100Gb/s InfiniBand and RoCE (based on the RDMA over Converged Ethernet standard) over 10/25/40/50/100GbE are supported with OFED by Mellanox to enable OEMs and System Integrators to meet the needs end users in the said markets.
