    Components

    Description

    Cisco Nexus 93180YC-EX

    10 Gbps & 25 Gbps TOR switches

    Cisco Nexus 9332PQ

    40 Gbps Aggregation switches

    Cisco Nexus 3172TQ

    1 Gbps & 10 Gbps Management switches

    Data Domain 

    2 x 10 Gbps links

    Application traffic

    2 x 25 Gbps links

    PowerFlex storage traffic

    2 x 25 Gbps links

    Architecture flow:

    • PowerFlex rack uses a pair of Cisco Nexus 93180YC-EX as TOR switches
    • PowerFlex rack uses a pair of Cisco Nexus 9332PQ as Aggregation switches
    • Cisco Virtual Port-Channel is configured between the TOR and Aggregation switches
    • Cisco Nexus 3172TQ switch is used for OOB traffic with 1 GbE dedicated network
    • Each node consists of four 25 GbE ports, two ports connected to each TOR (Cisco Nexus 93180YC-EX) switch
    • Both TOR (Cisco Nexus 93180YC-EX) switches have uplinks to aggregation (Cisco Nexus 9332PQ) switches for redundancy and network bandwidth aggregation
