I do not see the RDMA information like you showed in the Performance Monitor. I see a graph. Still network speeds are very low, like 2G. RDMA over Converged Ethernet (RoCE) or InfiniBand over Ethernet (IBoE)[1] is a network protocol that allows remote direct memory access (RDMA) over an Ethernet network. Join us at Mellanox Academy to learn about the capabilities of RDMA, various verbs objects and how to write and edit simple. Semantics (RDMA co mmunication model). Remote Direct. Memory Access (RDMA) [ 21] switch used was either a 24 po rt DDR Mellanox IB. switch or a 24 p ort Fulcrum Focal Point 10 GigE switch. Linux kernel starting from version 4.9 support sniffing RDMA(RoCE) traffic. tcpdump is extended to directly sniff/capture traffic using RDMA verbs making using of latest Linux ker. The need for QoS in RoCE Networks. RDMA was initially designed to be used in InfiniBand networks that run HPC applications. InfiniBand networks are lossless by specification, and HPC applications are usually optimized for network performance, hence have more network-friendly traffic. Therefore, HPC networks have lower demand for QoS configuration. This post provides a list of recommended Linux tools for configuring, monitoring and debugging RoCE traffic. The below information is applicable for Mellanox ConnectX-4 adapter cards and above, with the following SW: kernel version 4.11 and above, or MLNX_OFED version 4.2 and above.
