Deployment / Use Cases
This switch is ideal for data center spine-leaf architectures, where high-speed server connectivity must aggregate to faster backbone links. The 25GbE ports efficiently connect virtualized servers, storage arrays, and high-performance computing nodes, while the 100GbE uplinks provide sufficient bandwidth to core switches or routers.
Enterprise campus networks benefit from the Layer 3 capabilities for inter-VLAN routing, network segmentation, and policy-based traffic management. The 1U form factor makes it suitable for space-constrained rack environments in server rooms, data centers, and network closets.
Data Center Core
Serves as an aggregation switch in medium to large data centers, connecting 25GbE server racks to 100GbE spine switches with low latency and high throughput.
Enterprise Backbone
Functions as a distribution layer switch in campus networks, providing inter-building connectivity with advanced routing and security features.
Physical Profile
The switch features a standard 1U rack-mountable design with dimensions of 1.70" (43.18 mm) height, 17.50" (444.50 mm) width, and 18" (457.20 mm) depth. Weighing approximately 21.96 lb (9960.888445 g), it installs easily in standard 19-inch server racks with front-to-back airflow. The compact form factor maximizes port density while minimizing rack space consumption.
