Arista Networks, Inc. · 2026-11-03 · Importance 34 · Surprise 42

Arista said it is working with AI accelerator partners including Arm, Microsoft Maia, AMD Helios, Qualcomm and Meta MTIA on rack-scale Ethernet designs, including orthogonal, cable-intensive backplane and heterogeneous cross-rack configurations. Scale-up trials are expected to begin in 2027, with production expected in 2028; management said scale-up will not contribute materially in 2027. The company forecast more than 10 gigawatts of deployment across 10 or more compute accelerator types by the end of 2027, and expects AI fabrics revenue to reach approximately $7 billion in 2027.

Key facts

• Arista increased investment in liquid cooling, high-radix switching and AI software.
• Arista's AI-system work and partnerships require understanding each hyperscaler's unique requirements and constraints, and liquid cooling requires major infrastructure and technology upgrades.
