Description
The Juniper QFX5241-64QD-DO is a high-density, ultra-high-performance data center switch designed for modern leaf-spine and IP fabric architectures. Built to deliver extreme scalability and efficiency, it provides 64 QSFP-DD ports supporting up to 800GbE, enabling massive bandwidth consolidation in a compact 2U chassis.
Powered by a 51.2 Tbps switching fabric and Juniper’s Junos OS Evolved, the QFX5241-64QD-DO is optimized for large-scale data centers, AI/ML clusters, cloud infrastructure, and high-performance computing environments. Its DC power configuration with redundant hot-swappable power supplies and airflow-out (AFO) cooling ensures reliability and operational resilience in mission-critical deployments.
With advanced telemetry, automation readiness, and deep visibility, the QFX5241-64QD-DO enables operators to build scalable, deterministic, and highly efficient networks while reducing space, power, and operational complexity.
