Use Cases

Ethernet LAN connectivity for production servers — VM datastores (vSAN, NFS, iSCSI), management network, public/private isolation, RDMA over Converged Ethernet (RoCE) on 25G+ for HPC / AI training fabrics. SR-IOV for SDN. PXE boot. Compute clusters require matched-speed NICs (25G+ for Kubernetes CNI).
