This provides greater network scale while helping reduce power requirements and infrastructure footprint.

The platform can also support EVPN-VXLAN spine configurations as organizations move toward higher-speed data center architectures.

Flexible 400GbE Connectivity

The CX 9300 Series provides flexible breakout options for its 400Gbps ports.

Using breakout cabling, a 400Gbps port can be configured as:

• 4 x 100GbE
• 2 x 200GbE
• 1 x 400GbE

This flexibility allows organizations to adapt port configurations according to server, storage, and fabric connectivity requirements.

Common Operating Model

The Aruba CX 9300 Series can connect with several Aruba leaf switching platforms, including:

• Aruba CX 8325-48Y8C
• Aruba CX 8360-48Y6C
• Aruba CX 10000-48Y6C

This allows organizations to build scalable data center network architectures using multiple Aruba CX switching platforms.
