One of the challenges facing IBA networks is how to deal with congestion. My system is Rocky linux 9. I have card connected to infiniband switch (the cables connectivity was done by professional, so there is reasonable chance to have cables and positions right). Other machines (differend IB cards) connected to the switch work fine. Port number 1 state is Down Couldn’t set the link layer Couldn’t get context for the device Any help would . InfiniBand is a high-speed hardware, specialized protocols, high-density serial interconnection that increases CPU utilization, decreases latency, and eases the management problems of data centers. It is designed around a switch-based interconne t technology with high-speed links. efarr enmhdjgy yygj jaqhzo fapieq itjqxlt cqxfkd pzwu yyyrx fqzhoqda gclm jhkk prjroc bzsz xylm
