System overview
System features System components Network architecture

Network architecture

  • PowerFlex rack is available in two different network architectures to meet the requirements for different performance and scaling requirements.

    The architectures available are:
    • access and aggregation
    • leaf and spine

    Access and aggregation architecture

    The following figure is a high-level view of the physical PowerFlex rack using an access and aggregation architecture. This figure is not specific to a particular system, but is a generic representation.
    The following diagram shows the physical layout of the access and aggregation architecture:

    Leaf-spine architecture

    Leaf-spine architecture is 100 GbE connectivity from every spine to every leaf. Leaf-to-server node connectivity is offered in two options that are supported by different network switches.

    • 10 GbE or 25 GbE: Cisco Nexus 93180YC-EX or 93240YC-FX2 Switches
    • 100 GbE: Cisco Nexus 9336-FX2 or 9364C Switches
    The following figure is a high-level view of the physical PowerFlex rack designed using a leaf-spine architecture. This figure is not specific to a particular system, but is a generic representation.
