HPE Aruba CX 9300 32-Port QSFP-DD Overview

AI platforms, cloud infrastructure, and distributed applications generate large volumes of east-west traffic that require extremely high-bandwidth network fabrics to avoid performance bottlenecks.

400GbE Switching Built for AI and High-Performance Fabrics

The HPE Aruba CX 9300-32D provides 32 × QSFP-DD ports supporting 100GbE, 200GbE, or 400GbE connectivity. In a compact 1U design the switch delivers up to 25.6 Tbps switching capacity, enabling high-density connectivity for AI clusters, storage systems, and intra-fabric links. Data-centre and fabric-oriented switching architecture, together with AOS-CX telemetry and modern routing protocols, supports scalable east-west traffic patterns across leaf-spine and high-bandwidth aggregation designs.

Leaf-Spine Architecture Designed for Modern Data Centre Fabrics

Running the AOS-CX operating system, the platform supports modern fabric protocols including EVPN-VXLAN and advanced Layer-3 routing, allowing the switch to operate as a 100 GbE leaf or 400 GbE spine in scalable data centre networks. Organisations that do not require QSFP-DD and 400GbE capability may also consider the HPE Aruba CX 9300S 32-Port QSFP28 Switch, for supporting high-speed spine and storage fabrics.

Scaling AI and Cloud Infrastructure Without Network Bottlenecks

With high-density 400 GbE connectivity and integrated telemetry, the CX 9300-32D enables operators to scale compute clusters while maintaining predictable network performance across distributed workloads.

Our specialists can help design and deploy HPE Aruba CX 9300-32D switching solutions aligned to AI and high-performance data centre network fabrics.

HPE Aruba CX 9300 32-Port QSFP-DD Deployment Scenarios

 

The HPE Aruba CX 9300-32D 32-Port QSFP-DD Switch is designed for organisations that need high-density 100GbE, 200GbE, and 400GbE switching for modern data centre fabrics. It is best suited to large-scale cloud, storage, and compute environments where very high throughput and compact 1U density are key requirements.

400GbE Spine Fabrics

Large data centre fabrics often need dense 400GbE switching between spine and leaf layers. The CX 9300-32D is a strong fit where high-speed interconnects must scale without adding extra rack space.

High-Capacity Leaf Deployments

Leaf layers connecting modern servers and storage systems increasingly need flexible breakout from 400GbE to lower-speed links. This switch suits those designs by supporting dense server and storage connectivity in one platform.

Cloud and Virtualised Infrastructure

Cloud platforms and large virtualised estates generate heavy east-west traffic across the fabric. The CX 9300-32D is well matched to these environments where low latency and scale-out network design are central to performance.

Ethernet Storage Fabrics

Software-defined storage and HCI environments often need low-latency, loss-aware Ethernet behaviour across shared storage traffic. The CX 9300-32D is a practical fit where storage fabric performance must stay close to the workload.

Large Data Centre Pods

Some deployments need to support very large numbers of 25G or 100G server links within a single pod design. The CX 9300-32D is aimed at these larger environments where switching scale and port efficiency directly affect fabric design.

Planning an Aruba CX 9300-32D Deployment?

Our team can help design and deploy Aruba CX 9300-32D switching for 400GbE fabrics, cloud data centres, and high-scale storage networks.
