HPE Aruba CX 10040 32-Port QSFP28 Overview

High-performance data centre networks must support rapidly increasing east-west traffic generated by cloud workloads, AI platforms, and distributed applications.

High-Bandwidth Switching for Modern Data Centre Fabrics

The HPE Aruba CX 10040 32-Port QSFP28 Switch provides 32 × 100GbE QSFP28 ports and support for high-speed uplinks, enabling scalable connectivity for 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.

Switching Architecture Built for High-Speed Network Fabrics

The platform delivers up to 8 Tbps switching capacity with hardware-accelerated telemetry and security capabilities designed for large-scale data centre deployments. That helps operators scale server, storage, and application connectivity without losing visibility into traffic behaviour as workloads become more distributed and bandwidth intensive. Organisations that require QSFP-DD and 400GbE fabric density may also consider the HPE Aruba CX 9300-32D 32-Port QSFP-DD Switch, for scaling high-bandwidth server, storage and fabric interconnects in fewer switch nodes.

Supporting Scalable Infrastructure for High-Bandwidth Workloads

The CX 10040 enables organisations to expand data centre connectivity while maintaining reliable performance and network visibility as application demands grow. Better visibility and automation reduce manual troubleshooting effort, helping IT teams maintain reliable connectivity while the business adds devices, applications, and higher-speed network services.

Our specialists can help design and deploy HPE Aruba CX 10040 32-Port QSFP28 Switch solutions designed for high-performance data centre networks.

HPE Aruba CX 10040 32-Port QSFP28 Deployment Scenarios

 

The HPE Aruba CX 10040 32-Port QSFP28 Switch is designed for organisations that need higher-scale distributed services switching for modern data centre fabrics. It is well suited to cloud, AI-driven, and large-scale digital infrastructure where 100GbE leaf or spine connectivity and near line-rate security services are required.

High-Performance Data Centre Fabrics

The Aruba CX 10040 suits data centre fabrics that need high-density 100GbE switching for large server, storage, and application environments. It supports high-throughput fabrics where scale and integrated services both matter.

Cloud and AI Infrastructure

Cloud platforms and AI-driven services often generate large east-west traffic flows across the fabric. The Aruba CX 10040 is well suited to these environments because it combines high-capacity switching with distributed services and real-time operational insight.

Spine and High-Capacity Leaf Roles

Large fabrics often need switches that can operate as high-capacity leaf or spine layers depending on the design. The Aruba CX 10040 supports these deployments with dense 100GbE connectivity and 400GbE uplink options.

Security in the Data Path

Data centre environments that need segmentation and service insertion without separate appliance tiers can deploy the Aruba CX 10040 as part of a distributed services architecture. This helps keep security closer to the workload and fabric.

Next-Generation Digital Infrastructure

The Aruba CX 10040 is also a strong fit for environments modernising for cloud-native services, automation, and larger traffic volumes. It supports next-generation digital infrastructure where network scale and integrated security need to grow together.
