HPE Aruba Data Centre Switching

Application and storage traffic increases between servers, creating pressure on network throughput and latency. Bottlenecks at this layer affect application performance and recovery times. HPE Aruba Data Centre Switching addresses this with high-speed switching platforms designed for spine and leaf architectures, providing automation and visibility for large-scale data movement.

They are deployed in data centre fabrics connecting compute and storage systems. These platforms improve data transfer speeds, reduce latency, and support scalable infrastructure without frequent redesign.

Designing & Supporting HPE Aruba Data Centre Switching Solutions

Backed by decades of expertise in the IT sector, our specialists support every stage of your deployment — from initial selection through to long-term lifecycle management.

Tailored Switch Selection: Our specialists evaluate your network environment from the ground up — port density, uplink requirements, PoE budgets, VLAN complexity, and throughput demands all considered before a recommendation is made. Whether you’re refreshing an office access layer, connecting a factory floor, or building out a data centre fabric, you get the right switch for your environment, not an over-engineered or underpowered compromise.
Deployment & Integration: Our engineers manage end-to-end switch installation and network integration — cabling infrastructure, stack configuration, inter-VLAN routing, and integration with existing firewalls, wireless controllers, and management platforms — fully configured and tested so your team inherits a working network from day one.
Network Visibility & Security: Choosing the right management software and licensing is critical to getting full value from your switching infrastructure. Our specialists help you identify the right vendor platform for your needs — covering network-wide visibility, switch management, security monitoring, and analytics and reporting.

Industrial & Harsh Environments: Our team has hands-on experience deploying managed switches in demanding conditions — production facilities, outdoor enclosures, transportation infrastructure, and sites with extreme temperature, vibration, or dust exposure. We specify and commission ruggedised switching hardware built to perform where standard office-grade equipment would not.
Data Centre & High-Density Switching: Our consultants provide specialist guidance on spine-leaf architectures, 25/100GbE deployments, low-latency fabrics, and ToR switching configurations — helping your team build scalable, resilient data centre networks without starting the design process from scratch.
Lifecycle Support & Management: We provide proactive switch monitoring, firmware management, and support packages built around your network infrastructure — with remote diagnostic capability and response times matched to the criticality of each environment, from a branch office to a production data centre.
Strategy & Roadmapping: Our consultants run structured sessions to assess your current network architecture, identify bottlenecks and risk, and produce a clear switching roadmap — whether you’re consolidating a multi-site estate, planning a data centre refresh, or introducing managed switching to an industrial environment for the first time.

HPE Aruba Data Centre Switching FAQ

How do the five products within HPE Aruba Data Centre Switching divide by role?

The category divides into three groups. The CX 8400 (JL375A) is a modular 8-slot chassis for campus core and data centre core or spine-leaf roles. The CX 10000 and CX 10040 are DPU-enabled leaf switches that combine standard switching with built-in security services at the server edge. The CX 9300 and CX 9300S are high-capacity fixed spine switches for large-scale data centre fabrics at 100/400GbE speeds.

What security capability does the AMD Pensando DPU add to HPE Aruba Data Centre Switching leaf switches?

A standard switch moves traffic between servers but cannot inspect or filter it without routing traffic to a separate security appliance. The CX 10000 and CX 10040 include an AMD Pensando DPU that performs east-west firewalling, micro-segmentation, NAT, and encryption inline on every port. Internal traffic between servers no longer needs to travel to a centralised firewall for policy enforcement.

What is the difference between the CX9300-32D and CX9300S within HPE Aruba Data Centre Switching?

Both are fixed 1U spine switches with 100GbE and 400GbE connectivity. The CX9300-32D provides 25.6 Tbps with 32 ports configurable at 100GbE, 200GbE, or 400GbE — suited to the highest-throughput spine environments. The CX9300S provides 8 Tbps with 32 ports at 100GbE and 8 ports at 400GbE, offering a more cost-accessible path for environments transitioning server connections toward 400GbE fabric speeds.

What does the modular CX 8400 chassis offer in HPE Aruba Data Centre Switching that fixed switches do not?

The CX 8400 is an 8-slot chassis where line modules are purchased and installed separately, allowing port types and speeds to change without replacing the chassis. A single unit provides up to 19.2 Tbps across its slots. This suits environments that need a long hardware lifecycle or higher port density than a 1U fixed switch provides.

When does the CX10040-32 fit rather than the CX10000-48Y6C within HPE Aruba Data Centre Switching?

Both provide the same DPU-based security capabilities — east-west firewalling, micro-segmentation, and encryption inline. The CX10040-32 provides 8 Tbps with 32x100G and 6x400G ports; the CX10000-48Y6C provides 3.2 Tbps with 48x25G and 6x100G ports. The CX10040 suits environments where higher fabric throughput and 400GbE uplinks are required; the CX10000 suits access and leaf roles with 25G server connections.

Does HPE Aruba Data Centre Switching require cloud management, or can it run entirely on-premises?

All switches are fully manageable on-premises via CLI, REST API, and HPE Aruba Networking Fabric Composer, which handles fabric-wide provisioning without a cloud dependency. HPE Aruba Networking Central is optional. For the CX 10000 and CX 10040, the Pensando Policy and Services Manager provides on-premises management of DPU security functions independently of cloud services.
