High-performance data centre environments must support increasing east-west traffic generated by virtualised workloads, container platforms, and cloud infrastructure while maintaining reliable network visibility.
The HPE Aruba CX 9300S 32-Port QSFP28 Switch delivers high-density connectivity with 32 × 100GbE QSFP28 ports in a compact 1U form factor. The platform provides up to 6.4 Tbps switching capacity, enabling high-speed connectivity between servers, storage platforms, and aggregation layers within modern leaf-spine network architectures. 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.
Running the AOS-CX operating system, the switch supports modern data centre protocols including EVPN-VXLAN and advanced Layer-3 routing. This architecture allows the platform to operate as a high-bandwidth leaf or spine switch in scalable data centre fabrics. Organisations that require QSFP-DD and 400GbE fabric density may also consider the HPE Aruba CX 9300-32D 32-Port QSFP-DD Switch, for providing more headroom for AI, storage and east-west traffic growth.
Integrated telemetry and automation capabilities allow operators to monitor traffic flows, identify anomalies, and maintain operational insight across high-speed switching infrastructure.
Our specialists can help design and deploy HPE Aruba CX 9300S 32-Port QSFP28 Switch solutions aligned to high-performance data centre network fabrics.

The HPE Aruba CX 9300S 32-Port QSFP28 Switch is designed for organisations that need high-performance 100GbE switching with 400GbE uplink options for modern data centre and high-speed campus fabrics. It is best suited to environments that need strong 100G port density before moving fully into higher-density QSFP-DD designs.
Many data centres still build around dense 100GbE switching for compute, storage, and inter-switch traffic. The CX 9300S fits these fabrics where 100G server and fabric connectivity remains the main design standard.
Storage-led environments often need fast Ethernet switching with low latency and strong QoS characteristics. This model works well where software-defined storage or HCI platforms depend on reliable high-speed fabric behaviour.
Virtualised and cloud-style platforms need switching that can handle sustained east-west traffic across dense host estates. The CX 9300S is a good fit where high-speed switching supports large virtual machine or container environments.
Some enterprise designs use high-speed fixed switches to interconnect core services, data platforms, and private cloud resources. The CX 9300S suits these roles where 100GbE density is more important than maximum 400G port count.
Not every environment moves to higher uplink speeds at the same pace across the whole fabric. The CX 9300S is useful where organisations want strong 100GbE deployment today with room for faster uplinks as the network evolves.
Our team can help design and deploy Aruba CX 9300S switching for 100GbE fabrics, storage networks, and high-speed private cloud environments.
