NVIDIA Mellanox ConnectX-5 EN — 100GbE QSFP28
900-9X5AD-0016-ST1 — the NIC that carried the cloud generation, at pulled-part pricing.
Before 400G was mainstream, ConnectX-5 was the adapter inside a huge share of hyperscaler and HPC clusters — and for 100GbE compute nodes, storage and backbones it’s still exactly the right card. RDMA offload, RoCEv2, hardware timestamps: the features that make fast networks behave fast under load.
