The HPE Aruba Networking CX 8100 Switch Series serves the needs of modern campus core and aggregation as well as dynamic top-of-rack (ToR) data center environments, offering a flexible and innovative approach to addressing the application, security, and scalability demands of the mobile, cloud, and IoT.

The CX 8100 switches are based on HPE Aruba Networking CX Switch Operating System (AOS-CX) that automates and simplifies critical network tasks, offers programmability with REST APIs and Python scripts, delivers enhanced fault tolerance and zero-service disruption during planned or unplanned control-plane events. Real-time, network-wide visibility and analytics are available in every switch.

The series includes industry-leading line rate ports with 1/10 GbE (SFP/SFP+) and 40/100 GbE (QSFP+/QSFP28) connectivity in a compact 1U form factor. 4x10 Gbps and 4x25 Gbps break out from 40/100 G. These switches are great for customers needing 1 GbE/10 GbE with mix of fiber and copper ports.|

What's new

  • High-performance 1.76 Tbps of bidirectional switching and 1,309 Mpps of forwarding designed for aggregation in the campus or top-ofrack in data center environments.
  • Four different base models, each sold in bundles that support two airflow modes (Front to Back, and Back to Front) with Advanced Layer 2/3 feature set that includes BGP, OSPF, VRF, and IPv6.
  • High availability with industry-leading VSX redundancy and redundant power supplies and fans.
  • HPE Aruba Networking CX Switch Operating System (AOS-CX) automation and programmability using built-in REST APIs and Python scripts
  • Intelligent monitoring and visibility delivered by the HPE Aruba Networking Networks Analytics Engine (NAE) |
