Arista Networks, Inc. · 2026-11-04 · Importance 40 · Surprise 42

Arista CEO Jayshree Ullal described a shift toward a “network-centric approach” to AI, in which network performance affects AI factory productivity and GPU utilization. The company’s positioning includes support for diverse accelerators and networking across distributed AI deployments. Arista is also pursuing in-rack networking through its ESUN initiative; separately, Ullal said scale-up revenue is unlikely to be material until 2028, while the company sees Ethernet as a potential long-term challenger to proprietary scale-up technologies.
