Introduction Open Networking Networking best practices Network configurations Network design for Ready Stack scaling

Network configurations

  • Ready Stack systems can be built with Dell EMC PowerSwitch data center switches, which include:

    • Economical S-Series switches such as the S3048, S4048, and S4148 for OOB management 
    • High-performance S5058 and the new 25 GbE S5232 as ToR switches—leaf switches in a leaf/spine topology—for compute clusters
    • Extreme-performance Z-Series switches, such as the Z9264F at the spine layer, and new multiprotocol embedded blade switches such as the MX9116n for the PowerEdge MX7000 series blade-server chassis

    The following figure illustrates the Dell EMC PowerSwitch S5232F-ON VLTi configuration:

    Figure 4.              PowerSwitch S5232F-ON VLTi configuration

    In a Ready Stack reference architecture that includes an MX7000 PowerEdge blade server, the MX7116n chassis switch’s internal network ports that connect to the server’s network ports support the blade-server network traffic.

    vSphere Distributed Switch LAN traffic network configuration

    When using VMware as the hypervisor, customers can achieve bandwidth prioritization for different traffic classes such as host management, vSphere vMotion, and VM network using vSphere Distributed Switch (VDS) technology. The VDS, which can be configured, managed, and monitored from a central interface, provides:

    • Simplified VM network configuration
    • Enhanced network monitoring and troubleshooting capabilities
    • Support for network bandwidth partitioning when NIC Partitioning (NPAR) is not available

    The following diagram shows the VDS configuration. The dual-port FC host bus adapters are used for connecting to shared storage:

    Hyper-V Virtual Switch LAN traffic network configuration

    Hyper-V Virtual Switch is a software-based layer-2 Ethernet network switch that is available in Hyper-V Manager when you install the Hyper-V server role. Hyper-V Virtual Switch includes programmatically managed and extensible capabilities to connect VMs to both virtual networks and the physical network.

    Hyper-V Virtual Switch provides:

    • Simplified VM network configuration
    • Policy enforcement for security, isolation, and service levels
    • Enhanced network monitoring and troubleshooting capabilities
    • Support for network traffic segmentation

    The following figure shows the Hyper-V Virtual Switch configuration for the management and compute servers. The dual-port FC host bus adapters are used for connecting to shared storage:
