Product Overview
The QFX5230-64CD is a 2U fixed-configuration switch featuring 64×400GbE ports, 600 ns latency, 112 MB packet buffer, 51.2 Tbps bidirectional throughput, and Junos OS Evolved – purpose-built for AI data center spine/super-spine layers and EVPN-VXLAN IP fabrics.
Key Differentiators
Ultra-Low Latency – 600 ns (unicast, cut-through mode) – ideal for AI/ML and HPC workloads.
Massive Packet Buffer – 112 MB total buffer absorbs burst traffic without dropping packets.
High-Density 400GbE – 64×QSFP56-DD ports (16 support 400G-ZR/ZR-M optics); breakout to 128×200GbE, 256×100GbE, or 256×25GbE.
High Throughput – 25.6 Tbps unidirectional / 51.2 Tbps bidirectional; 10.53 Bpps forwarding capacity.
Broadcom Tomahawk 4 – BCM56990 ASIC with Junos OS Evolved for proven reliability.
Carrier-Grade Redundancy – 1+1 hot-swappable power supplies; 7+1 hot-swappable fan modules.
Flexible Cooling – Port-to-FRU (AFO) or FRU-to-port (AFI) options for data center airflow optimization.
Cloud Management – Juniper Mist Wired Assurance with AI automation and ZTP.
Advanced Telemetry – Junos Telemetry Interface (JTI), sFlow, SPAN/RSPAN/ERSPAN.
