RoCE or iWARP for Low Latency?

[Todd_Owens]

Today, Remote Direct Memory Access (RDMA) is primarily being utilized within high performance computing or cloud environments to reduce latency across the network.  Enterprise customers will soon require low latency networking that RDMA offers so that they can address a variety of different applications, such as Oracle and SAP, and also implement software-defined storage using Windows Storage Spaces Direct (S2D) or VMware vSAN.  There are three protocols that can be used in RDMA deployment: RDMA over InfiniBand, RDMA over Converged Ethernet (RoCE), and RDMA over iWARP.  Given that there are several possible routes to go down, how do you ensure you pick the right protocol for your specific tasks?
