Product overview

The HPE R1N28A Composable Fabric FM 3032Q is a high-performance 1RU switch module engineered for modern data centers, featuring 32 QSFP28 ports that support 100GbE and breakout to 25GbE for dense server connectivity. With back-to-front airflow, it ensures efficient cooling in rack environments. This module enables flat, wire-once topologies with programmatic control via HPE's composable infrastructure, simplifying management and scaling from top-of-rack to spine deployments. Ideal for cloud providers, HPC clusters, and enterprise fabrics requiring low-latency, non-blocking 100GbE performance. Broad compatibility with existing Ethernet infrastructure reduces migration costs while delivering wire-speed forwarding across all ports. Deploy in Synergy composable systems or standalone racks for flexible networking.
