RoCE Vs. IWARP Competitive Analysis Brief
Internet Wide Area RDMA Protocol (iWARP) and RDMA over Converged Ethernet (RoCE) are the two commonly known Remote Direct Memory Access (RDMA) technologies over Ethernet. Introduced in 2002, iWARP solutions over Ethernet have seen limited success due to implementation and deployment challenges. Benchmarks results published by lead iWARP technology providers, show 6usec latency that Mellanox standard Connectx-2 Ethernet technology supports today. Since the scaling and ROI needs in Web 2.0 and Cloud Computing have not been able to be met by iWARP, a more advanced RDMA over Ethernet technology was required.
