Rack-mountable chassis
Aruba CX 8100 platform

Built for networks that cannot afford congestion at the aggregation or core edge, the Aruba CX 8100 48x10G SFP+ 4x40/100G QSFP28 switch delivers a dense mix of high-speed access and uplink capacity. With 48 10 Gigabit SFP+ ports and 4 QSFP28 uplinks supporting 40G and 100G speeds, it is designed to carry heavy east-west traffic, server connectivity, and backbone aggregation without forcing immediate redesign. Layer 3 management gives architects the routing control needed for segmented environments, routed access, and cleaner traffic paths between critical network zones. The rack-mountable chassis and back-to-front airflow align with data center deployment practices where thermal direction and serviceability matter. Compared with lower-speed aggregation switches, this model gives you room to grow into higher-throughput workloads. Compared with smaller edge switches, it reduces the number of devices needed to support dense fiber connectivity and high-speed uplinks. For teams standardizing on Aruba infrastructure, it offers the port density and uplink headroom that justify a premium placement in the network stack.

Ideal For

Deploy as a data center aggregation switch for server and storage uplinks
Use in a campus core or distribution layer where Layer 3 routing is required
Connect high-speed fiber endpoints across virtualization, backup, and application networks
Build a backbone uplink tier with 100G-capable aggregation paths

Why This Product

1Higher uplink capacity than 10G-only aggregation switches
2Layer 3 control supports routed designs and segmented traffic paths
3100G QSFP28 uplinks suit backbone and core connectivity
4Better fit for dense fiber environments than access-layer switches
