AI clusters create synchronized traffic bursts instead of smooth enterprise-style flows. That shift changes the network design target from “average utilization” to deterministic tail-latency and drop control during collective operations.
This unit frames Cumulus Linux as an operational layer in a larger Spectrum-X system. Use it to build a cause-and-effect mental model before touching CLI: GPU workload behavior is directly coupled to fabric loss, congestion response, and control-plane consistency.
