## Summary description

HPE Aruba CX 8100 is a managed Layer 3 data center switch offering 40 10GBase‑T RJ‑45 ports, 8 10G SFP+ ports and 4 QSFP28 slots supporting 40/100G. It delivers 1,760 Gbit/s switching capacity and a 147,456‑entry MAC table, includes RJ‑45 and USB‑C console, front‑to‑back airflow, 1U rack form factor and redundant dual AC power supplies for resilient 10G Ethernet aggregation and distribution.

## Long description

The HPE Aruba Networking CX 8100 is a compact 1U managed Layer 3 switch designed for campus core, aggregation, and top-of-rack data center roles. It combines a mix of 40 x 10G Base-T RJ-45 ports, 8 x 10G SFP+ ports and 4 x 40/100G QSFP28 ports, with support for 4x10G and 4x25G breakout from 40/100G interfaces. The switch runs AOS-CX, a modern, modular operating system that offers programmability, embedded analytics, and high-availability features to support mobile, cloud and IoT workloads.
Advantages
AOS-CX provides REST APIs and Python scripting for automation and integration, while the embedded Aruba Network Analytics Engine delivers real-time visibility and telemetry for proactive troubleshooting. The platform uses a microservices architecture with continual state synchronization and dual control-plane support to reduce service disruption and improve fault tolerance. High-density line-rate 1/10/40/100GbE connectivity in a 1U form factor supports mixed copper and fiber deployments and simplifies consolidation at the campus core or ToR layer.
Suitable for
Campus core and aggregation switches in enterprise networks
Top-of-rack (ToR) deployments in data centers needing mixed 10G and 40/100G ports
Environments requiring programmability and automation via REST APIs and Python
Networks that benefit from embedded analytics and telemetry for troubleshooting and capacity planning
When it may not be suitable
This switch is targeted at enterprise and data center environments; it may be oversized or more feature-rich than necessary for small offices or simple unmanaged switching needs. Additionally, if an environment requires only low-port-count or solely 1GbE ports, a different lower-capacity model could be more cost-effective.
Key specifications
Form factor: 1U rack-mountable chassis
Ports: 40 x 10GBase-T (RJ-45), 8 x 10G SFP+, 4 x 40/100G QSFP28 (with 4x10G and 4x25G breakout support)
Switching capacity: 1760 Gbit/s
MAC address table: 147,456 entries
Management: Managed L3 with REST APIs and Python scripting
Console: RJ-45 and USB Type-C
Redundancy: Dual AC power supplies supported; modular high-availability design
Cooling: Front-to-back airflow with 3 fans
How to use
Install the 1U chassis in a standard rack and connect AC power supplies. Use the console port or network management interfaces to access AOS-CX for initial configuration. Configure VLANs, routing, QoS, ACLs and other L3 services as required. Use REST APIs or Python scripts to automate provisioning and integrate with orchestration tools such as Aruba Fabric Composer. Monitor performance and health with the embedded Network Analytics Engine and Time Series Database for telemetry and trend analysis.
What to consider before purchase
Required port types and counts (mix of copper 10GBase-T, SFP+ and QSFP28)
Whether 40/100G breakout capability (4x10G / 4x25G) is needed
Power and cooling requirements for a 1U, front-to-back airflow unit
Need for AOS-CX features such as REST APIs, embedded analytics and VSX high-availability
Compatibility with existing cabling and transceivers (copper vs. fiber)
Usage recommendations
Deploy the CX 8100 in aggregation or ToR roles where a mix of high-density 10G ports and 40/100G uplinks is required. Enable the Aruba Network Analytics Engine and REST API access during commissioning to capture telemetry and automate routine tasks, and consider dual power supplies and VSX configurations for critical high-availability needs.
