PowerFlex rack

PowerFlex rack

  • The PowerFlex rack comes preinstalled with integrated top-of-rack (ToR), aggregation, and out-of-band (OOB) management switches to provide optimal network traffic flow. The PowerFlex rack includes Cisco Nexus aggregation switches that provide 10/40 GbE IP uplink connectivity to the external network for superior performance. Often, network bottlenecks can limit the scale of an HCI system. The 10/25 GbE ToR switches in the PowerFlex system eliminate these restrictions and provide a path for future growth.
