HPE CX 9300 Layer 3 Switch

The HPE Aruba Networking CX 9300 Layer 3 Switch is a high-density, 1U fixed configuration engineered to meet the demands of modern data centers. With robust 25.6 Tbps switching capacity and support for 32 ports of 100/400 GbE, this switch is built to handle dense server attachments, high-speed storage interconnects, and expansive intra-fabric connectivity. Designed to integrate seamlessly with Aruba CX OS, the CX 9300 delivers reliable routing, automation-ready management, and a scalable fabric that simplifies operations while accelerating deployment of new workloads.

• Extreme density and performance in a compact 1U form factor: At the heart of the CX 9300 is an impressive 25.6 Tbps switching capacity paired with 32 lanes of high-speed 100/400 GbE connectivity. This combination enables direct, non-blocking paths between servers and storage and supports large-scale leaf-spine topologies without forcing compromises on latency or bandwidth. The 1U footprint minimizes rack-space usage while maximizing port density, helping data centers reduce cabling complexity and power consumption per terabit of throughput.
• Flexible, cost-efficient 400 GbE connectivity for data center fabrics: The CX 9300 is purpose-built for high-density 400 GbE deployments that power modern data center fabrics. By delivering fixed configuration with high port speed, it eliminates the need for expensive modular chassis while preserving the performance needed for AI workloads, virtualized environments, and dense server tiers. This translates to lower total cost of ownership and faster time-to-value as you scale out your infrastructure.
• Advanced Layer 3 routing with comprehensive fabric visibility: Beyond switching, the CX 9300 provides robust Layer 3 capabilities to drive efficient East-West traffic. Expect dynamic routing, VRFs, ACLs, and QoS policies that help isolate tenant traffic, optimize latency, and guarantee performance levels for critical applications. Aruba CX OS delivers a consistent, policy-driven approach to network operations, enabling predictable outcomes across the entire fabric and simplifying troubleshooting with clear visibility into forwarding and routing decisions.
• Intelligent automation and proactive operations: The CX 9300 is designed for automation-first deployments. Through its programmable interfaces, RESTful APIs, and integration with Aruba CX OS, you can automate provisioning, configuration rollout, and policy enforcement across the fabric. This capability reduces manual tasks, accelerates scale-out, and ensures consistent configurations across multiple switches, contributing to faster deployment cycles and fewer human errors.
• Resilience, security, and scalable management: Built for data center uptime, the CX 9300 emphasizes reliability and secure management. The OS supports role-based access control, secure administration, and operational tooling that helps you detect and respond to issues quickly. With a scalable management model, IT teams can extend visibility and control as the network grows, while maintaining performance for latency-sensitive workloads and ensuring a safer, more manageable network environment.
