Product Features
Technical Overview
This switch supports optical fiber media exclusively across all its ports, enabling long-distance, high-bandwidth connections between servers, storage arrays, and network core components. The 25GBase-X and 100GBase-X network technologies provide efficient, low-latency data transmission suitable for virtualization, high-performance computing, and storage networking workloads.
With 22 total expansion slots, the switch offers flexible configuration options. The SFP28 slots accept 25GbE optical transceivers or direct-attach cables, while the QSFP28 slots support 100GbE optics or breakout configurations to multiple lower-speed ports. Layer 3 support includes dynamic routing protocols, VLAN routing, and access control lists for segmented network architectures.
This section brings together practical product details such as Port/Expansion Slot Details, Media Type Supported, Ethernet Technology, Network Technology, so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.
Key Product Advantages
The Aruba CX 8325H delivers critical advantages for network architects building next-generation infrastructure. Its high port density at 25GbE meets growing bandwidth demands from servers and storage, while the 100GbE uplinks provide ample headroom for aggregation and future expansion.
Scalable Layer 3 Design
Full Layer 3 routing capabilities enable complex network segmentation, dynamic routing between VLANs, and scalable enterprise or data center designs without requiring external routers.
- Dynamic routing protocol support
- Inter-VLAN routing
- Access control lists
Reliability & Serviceability
Front-to-back airflow aligns with standard data center hot aisle/cold aisle configurations, while dual hot-swappable power supplies and four fans ensure continuous operation.
- Hot-swappable PSUs
- Redundant cooling
- TAA compliance
High-Speed Connectivity
18 SFP28 ports deliver 25GbE to servers and storage, while 4 QSFP28 ports provide 100GbE uplinks for core connectivity or spine-leaf architectures.
- 25GbE server connectivity
- 100GbE uplink capacity
- Optical fiber support
Deployment / Use Cases
This switch is engineered for deployment scenarios requiring high-bandwidth aggregation and reliable Layer 3 routing. Its 1U rack-mountable form factor makes it suitable for standard data center racks, while the front-to-back airflow integrates seamlessly with raised-floor cooling systems.
Primary use cases include data center leaf-layer switching in spine-leaf architectures, where the 25GbE ports connect to servers and the 100GbE ports uplink to spine switches. It also serves effectively as a core switch in medium-sized enterprise networks, providing high-density 25GbE connectivity for virtualized server farms and all-flash storage arrays.
Data Center Leaf Switch
Deploy as a leaf switch in spine-leaf architectures, connecting servers and storage via 25GbE while using 100GbE uplinks to spine switches for scalable fabric design.
Enterprise Core Aggregation
Serve as a core aggregation switch in enterprise networks, routing between departmental VLANs while providing high-speed connectivity to data center resources.
Physical Profile
The switch occupies 1U of rack space with dimensions of 1.69" height, 8.27" width, and 22.72" depth. Its 13.10 lb weight makes it manageable for standard rack installation. The front-to-back airflow design matches common data center cooling layouts, with ports and indicators on the front and power supplies and exhaust on the rear.
The physical profile is practical for deployment planning because the dimensions and weight are clearly defined: 1.69" (43 mm), 8.27" (210 mm), 22.72" (577 mm), 13.10 lb (5940 g). This helps confirm rack, shelf, desk, or cabinet fit before installation.
