RoCE defines how to perform RDMA over Ethernet while the InfiniBand architecture specification defines how to perform RDMA over an InfiniBand network. RoCE was expected to bring InfiniBand applications, which are predominantly based on clusters, onto a common Ethernet converged fabric. Others expected that InfiniBand will keep offering a higher bandwidth and lower latency than what is possible over Ethernet. WebThe simple configuration to make it appear is adding the line ib_ipoib in /etc/rdma/modules/infiniband.conf then rebooting the system. After booting the system with the module ib_ipoib, links with the name like ibp16s0 should be confirmed with the command ip link .
