Juniper QFX5230-64CD-D-AFO 64x400G QSFP56-DD Switch | Data Center

Build a faster fabric without adding more boxes. The Juniper QFX5230-64CD-D-AFO delivers 64 x 400G QSFP56-DD ports for high-density leaf, spine, and super-spine deployments where port count and throughput matter more than chassis size. It is built for environments that need to move large volumes of east-west traffic with fewer hops and tighter rack economics. This model is a strong fit for operators standardizing on 400G infrastructure for AI clusters, storage-heavy workloads, and large virtualization domains. The dense port layout helps reduce oversubscription pressure while keeping cabling and rack planning more predictable. AC front-to-back airflow supports common data center cooling patterns, making it easier to align with existing thermal design. For teams comparing against lower-density switches, the value is in consolidation: fewer devices to manage, fewer interconnects to plan, and more headroom for growth. That matters when the network is part of the application performance budget, not just the transport layer.
