RDMA Networking

The Device Manager publishes usable remote direct memory access (RDMA) endpoints as Kubernetes resources. Workloads request a count; kubelet decides which endpoints a container receives.

RDMA requests

RDMA Operations covers the resource keys, endpoint counts and kubelet TopologyManager policy. It also explains why Kueue admission alone does not reserve an interface.

Follow RDMA Networking Walkthrough to request and verify endpoints and non-uniform memory access (NUMA) alignment.

Interface discovery

Network Topology describes the interface inventory, link checks and labels the Device Manager reports.
