25 GbE network equipment summary


  • The number of cables that are needed for a cluster are summarized in:

     Table 7.  Per-rack network equipment 
    ComponentQuantity
    Total racksOne (12 nodes nominal)
    Management switchOne PowerSwitch S3100-ON family
    Switch interconnect cableOne 1 GbE cable (to the next rack management switch)
     Table 8.  Per-pod network equipment
    ComponentQuantity
    Total racksThree (36 nodes)
    ToR pod switchesTwo PowerSwitch S5248F-ON
    Pod uplink cablesFour 100 Gb QSFP+ cables (to the aggregate switch)
    ToR VLT cablesTwo 25 Gb SFP28 cables
     Table 9.  Per-cluster aggregation network switches for multiple pods 
    ComponentQuantity
    Total PodsEight
    Aggregation layer switchesTwo PowerSwitch Z9432F-ON

    See the PowerSwitch Z9432F-ON Spec Sheet for more information about the Z9432F-ON.

    The required cluster networking equipment is summarized in Table 10.

     Table 10.   Per-node network cables required 
    Description1 GbE cables25 GbE connections
    Master nodesOne per nodeTwo per node
    Edge nodesOne per nodeFour per node
    Worker nodesOne per nodeTwo per node
    Note: 25 GbE node connections typically use a QSFP28 (100 Gbps) to SFP28 (25 Gbps) breakout cable. The cable count is typically one-fourth the number of connections in Table 10.
