Product overview

The HPE Aruba Networking CX 8100 R9W86A is a high-performance 1U switch bundle designed for demanding data center, campus, and branch environments. It features 24x 10G SFP+ ports for high-density server connectivity and 4x 40/100G QSFP28 uplinks for core aggregation, enabling wire-speed L3 switching with full-duplex throughput exceeding 1.92 Tbps. Front-to-back airflow ensures efficient cooling in rack deployments, supported by 3 fan trays and dual hot-swappable AC power supplies for redundancy. Built on Aruba CX OS, it offers advanced programmability, zero-touch provisioning, and integration with Aruba Central for simplified management. Ideal for spine/leaf architectures, it supports EVPN/VXLAN overlays, dynamic segmentation, and REST APIs for automation, reducing operational complexity while delivering sub-microsecond latency for AI/ML, HPC, and cloud workloads. Scalable from edge to core, this switch enhances network agility and reliability in enterprise infrastructures.
