Aruba CX 9300X-32D (R9A29A/R9A30A) - 32 × 400 GbE QSFP-DD High-Density Core/Aggregation Switch

Aruba CX 9300X-32D is a high-performance, 1U data-center–class switch built for next-generation campus core, aggregation, and spine deployments. It delivers 32 × 400 GbE QSFP-DD ports for ultra-high-density 400 Gbps connectivity, enabling up to 25.6 Tbps switching capacity with sub-microsecond latency.  Powered by the ArubaOS-CX operating system, the CX 9300X-32D provides advanced automation, real-time telemetry, and deep programmability for large enterprise and cloud environments.

Integrated network analytics and streaming telemetry support proactive troubleshooting and simplified operations, while EVPN-VXLAN offers scalable multi-site overlays and seamless Layer 2/Layer 3 segmentation. The platform includes redundant, hot-swappable power supplies and fan trays for continuous availability, with flexible front-to-back or back-to-front airflow options to match data-center cooling strategies. Two SKUs are available to meet different deployment needs:

• R9A29A – Front-to-back airflow model
  
• R9A30A – Back-to-front airflow model
  

This combination of massive port density, wire-speed performance, and resilient architecture makes the Aruba CX 9300X-32D an ideal choice for cloud data centers, service-provider cores, and large enterprise backbones requiring 400 GbE aggregation and spine connectivity.

ADVANCED FEATURES:

High-Performance 400GbE Switching Fabric:

The Aruba CX 9300X-32D delivers 25.6 Tbps non-blocking switching capacity with a forwarding rate of 8,000 Mpps, ensuring high-speed performance for core and aggregation deployments. With large packet buffers and a scalable MAC address table, it efficiently handles bandwidth-intensive applications such as AI/ML clusters, high-speed storage, virtualization, and cloud services while maintaining low latency under heavy multi-service loads.

AI-Driven Telemetry & Analytics:

Powered by ArubaOS-CX, the switch offers real-time and historical telemetry via a built-in time-series database. Advanced analytics, combined with REST APIs and Python scripting, enable automation, granular insights, and proactive network optimization. IT teams can configure custom dashboards, alerts, and reports to quickly identify bottlenecks or potential failures.

High Availability & Resilience:

The CX 9300X-32D ensures continuous operation through dual redundant hot-swappable AC power supplies and hot-swappable fan trays. It supports VSX (Virtual Switching Extension), allowing two switches to operate as a single logical system, providing seamless failover and simplified multi-chassis management. Non-disruptive software upgrades reduce downtime during maintenance or configuration changes.

Flexible Deployment Options:

This model is available in two SKUs to match airflow and power requirements:

• R9A29A – Front-to-back airflow
• R9A30A – Back-to-front airflow

This flexibility allows deployment in diverse data center and campus environments, aligning with existing cooling strategies and rack layouts.

Advanced Security & Compliance:

The CX 9300X-32D provides MACsec AES-256 encryption on all ports, 802.1X authentication, role-based access control, and ACLs across L2–L4. Additional protections include DHCP snooping, Dynamic ARP Inspection (DAI), and IP Source Guard. Compliance with RoHS, CE, and UL ensures enterprise-grade safety and regulatory adherence.

Scalability & Future-Ready Architecture:

Designed for evolving enterprise networks, the switch supports EVPN-VXLAN, advanced L2/L3 routing, and massive IPv4/IPv6 route scaling. It allows seamless migration to higher-bandwidth infrastructures while supporting multi-tenant and cloud-ready architectures, ensuring consistent performance as networks scale.

Automation & Cloud Integration:

ArubaOS-CX integration provides centralized management, Zero-Touch Provisioning (ZTP), automation via REST APIs and Python scripting, and predictive analytics. IT teams can deploy and manage large-scale networks efficiently with minimal manual intervention.

Enhanced Monitoring & Troubleshooting:

Built-in telemetry and analytics tools enable real-time monitoring of traffic, port health, and performance trends. Detailed logging and alerting mechanisms allow rapid response to network events, ensuring consistent service levels for critical campus and data center applications.
