Arista Networks said on Oct 7, 2026 it is releasing an open Ethernet rack‑scale portfolio for AI infrastructure. The platforms support both scale‑up (single large chassis) and scale‑out (multiple racks) designs. Arista worked with compute partners including AMD, Arm, Broadcom, d‑Matrix, Meta, Microsoft and Qualcomm. The effort is part of the Ethernet for Scale‑up Networks (ESUN) initiative.
Why it matters
The portfolio gives data‑center operators a standardized, high‑density networking option for building larger or more flexible AI clusters.
