Dell PowerSwitch Z9432F-ON

The Dell EMC PowerSwitch Z9432F-ON is a 400GbE-capable spine switch that operates at the top tier of modern data center fabric designs, built on the Broadcom Tomahawk 4 ASIC with 25.6 Tbps of total switching capacity. Its 32x QSFP-DD ports support 400GbE native or can be broken out to 128x 100GbE via QSFP-DD-to-QSFP28 fan-out cables, making it an extremely flexible spine layer device that can serve as the aggregation point for hundreds of 100GbE leaf-to-spine links in a large-scale leaf-spine fabric. This breakout capability extends the reach of a single spine switch considerably compared to previous-generation 100GbE spine platforms.

The Z9432F-ON runs Dell Enterprise SONiC Distribution, which provides full BGP EVPN/VXLAN spine functionality, ECMP with up to 512 equal-cost next-hops for traffic load distribution, and gNMI/gRPC telemetry streaming compatible with open-source observability stacks such as Prometheus, Grafana, and ELK. The SONiC platform enables continuous container-based NOS updates without switch reboots for many update types, aligning with CI/CD-style infrastructure change management practices increasingly adopted in enterprise network operations.

The Z9432F-ON is targeted at large enterprise data centers that are scaling to 400GbE server connectivity or that need to aggregate very large numbers of 25/100GbE leaf switches into a non-blocking or minimally oversubscribed spine. It competes directly with Cisco Nexus 9000-series and Arista 7800-series in the spine tier and is a preferred platform for organizations standardizing on Dell PowerSwitch end-to-end to reduce multi-vendor complexity in NOS management and support.

Ideal for

• Data center spine layer in large-scale 25GbE/100GbE leaf-spine fabric architectures
• 400GbE interconnect for hyperscale-class enterprise or colocation data centers
• Core aggregation switch for multi-site campus and DCI (Data Center Interconnect) designs
• VXLAN BGP-EVPN spine router for multi-tenant private cloud fabric
• High-performance computing cluster interconnect fabric spine
• Large-scale AI/ML training cluster network aggregation
