About the HPE Aruba Networking CX 8325 Data Center Switch

The HPE Aruba Networking CX 8325 is a purpose-built data center switching platform designed to serve as both a high-performance spine and a top-of-rack leaf node in modern spine-leaf architectures. Built on a merchant silicon ASIC foundation, the CX 8325 delivers wire-rate forwarding across all ports with a non-blocking switching capacity that accommodates the demanding traffic profiles of AI/ML workloads, high-frequency storage access, and east-west data center communication. The platform supports multiple port configurations optimized for either 25GbE server connectivity at the leaf layer or 100GbE uplinks and spine interconnects, enabling seamless scaling without architectural redesign.

At the software level, the CX 8325 runs HPE Aruba's AOS-CX operating system, which provides a modern, REST API-native network operating environment with a full suite of data center protocols including BGP EVPN with VXLAN data plane encapsulation for scalable Layer 2 and Layer 3 overlay fabrics. The switch supports VSX (Virtual Switching Extension) for active-active redundancy without legacy spanning-tree dependencies, Segment Routing, and comprehensive Quality of Service mechanisms. The AOS-CX architecture separates the control plane from the data plane and offers an in-service software upgrade capability, enabling zero-disruption maintenance windows critical to always-on enterprise environments.

The CX 8325 is notable for its integration with HPE Aruba Fabric Composer and HPE Greenlake cloud-native management, allowing operators to automate provisioning, monitor fabric health telemetry in real time, and enforce policy at scale through programmable interfaces. Its deep buffer architecture absorbs traffic microbursts common in GPU cluster interconnects and NVMe-over-Fabrics storage networks, while its compact 1U or 2U form factor maximizes rack density. Together, these characteristics position the CX 8325 as a foundational building block for enterprises modernizing their data center network infrastructure through open-standards-based fabric designs.

Ideal for

  • Spine-leaf fabric backbone for hyperconverged infrastructure deployments requiring high-bandwidth, low-latency east-west traffic forwarding between compute nodes.
  • AI and machine learning cluster interconnect providing lossless 25/100GbE connectivity between GPU servers with priority flow control and ECN-based congestion management.
  • NVMe-over-Fabrics (NVMe-oF) storage networking enabling all-flash array connectivity with predictable sub-microsecond latency across the storage fabric.
  • Multi-tenant cloud data center segmentation using EVPN-VXLAN overlays to provide scalable Layer 2 and Layer 3 virtual network isolation across thousands of tenants.
  • Data center migration and modernization projects transitioning legacy three-tier architectures to automated BGP-based spine-leaf topologies with zero-disruption cutover using AOS-CX VSX.
  • Edge data center and colocation deployments requiring high port density in a compact footprint with cloud-managed visibility through HPE Greenlake integration.
