A municipal GPU cluster needs near-lossless behavior for RoCE storage traffic across the IP fabric. Which CoS approach belongs in the fabric design?
Select an answer to reveal the explanation.
Short Explanation
RoCE storage is like a glass elevator—one hard bump and the ride goes badly. Give those queues the lossless-ish toolkit (PFC/ECN-style patterns on the right paths) instead of treating GPUs like best-effort web downloads.
Full Explanation
RoCEv2/RDMA workloads are sensitive to loss and congestion. IP fabric CoS for these apps typically includes careful classification plus mechanisms such as Priority Flow Control and ECN on the RDMA-capable segments. Disabling QoS, demoting all traffic to scavenger, or prioritizing only HTTP management does not provide the CoS support RoCE storage needs.
