PowerFlex rack is available as two different network architectures to meet the requirements for different performance and scaling requirements.
Access and aggregation architecture
The following figure is a high-level, system layout of the PowerFlex rack using an access and aggregation architecture. This figure is not specific to a particular system, but is a generic representation.

The following figure shows the logical layout of the access and aggregation architecture:
The following diagram shows the logical layout of the access and aggregation with management aggregation architecture:
Leaf-spine architecture
Leaf-spine architecture is 100 GbE connectivity from every spine to every leaf. Network switches provide two options to support leaf-to-node connectivity.
- 10 GbE or 25 GbE: Cisco Nexus 93240YC-FX2 switch
- 100 GbE: Cisco Nexus 9336-FX2, or 9364C or 9364-GX switches
