    Overview

    Arista DCS-7280CR3K-32D4# Overview

    The Arista DCS-7280CR3K-32D4# is a high‑performance data center switch engineered for demanding spine, leaf, and aggregation roles. With 32 x 100GbE QSFP interfaces, it delivers 6.4 Tbps of non‑blocking throughput and a forwarding rate of 3 billion packets per second, ensuring wire‑speed performance for cloud and enterprise workloads. Sub‑microsecond latency and a compact 1RU footprint make it ideal for latency‑sensitive environments. Front‑to‑back airflow and a typical 350W power profile support efficient operation in modern hot‑aisle/cold‑aisle data centers.
