HPE Juniper Networking QFX5120-32C-AFO 32x 100GbE network switch

High-density 100GbE data-centre switch

The HPE Juniper Networking QFX5120-32C-AFO is a managed 1U rack-mount switch built for high-density 100GbE connectivity. It provides 32 QSFP28 ports plus four uplink ports supporting SFP+, QSFP+ and QSFP28 transceivers. Data-centre operators and cloud providers needing massive aggregate bandwidth in a single rack unit will fit this platform into existing rows without redesigning aisle layouts.

Front-to-rear airflow matches standard hot-aisle

The AFO suffix denotes front-to-rear airflow, so cool air enters the front bezel and exits toward the hot aisle, matching conventional data-centre cooling designs. AC power supplies feed the chassis from the rear, keeping cable routing consistent with other 1U gear in the same rack. The compact form factor leaves vertical space for patch panels or additional switches while the managed operating system handles configuration through standard network-management tools.

6.4 Tbps capacity with 4.76 Bpps throughput

A multi-core x86 processor, 8 GB DRAM and 64 GB SSD drive the control plane while the ASIC delivers 6.4 Tbps switching capacity and 4.76 Bpps forwarding throughput. This headroom absorbs bursty HPC, storage and AI workloads without queuing latency. Power draw scales with populated ports and traffic load; the AC supplies are sized for full 32-port operation at line rate, so thermal output remains predictable inside a cooled rack.
