Physical network components

  • Ready Solutions for VDI on appliances enable flexibility in networking selections. VDI validations have been successfully performed with the following hardware, although several other choices are available:

    • Dell EMC Networking S4048-ON (10 GbE ToR switch)—The S4048-ON switch optimizes your network for virtualization with a high-density, ultra-low-latency ToR switch that features 48 x 10 GbE SFP+ and 6 x 40 GbE ports (or 72 x 10 GbE ports in breakout mode) and up to 720 Gbps performance. The S4048-ON switch also supports ONIE for zero-touch installation of alternate network operating systems.
    • Dell EMC Networking S5248F-ON (25 GbE ToR switch)—The S5248F-ON switch provides optimum flexibility and cost-effectiveness for demanding compute and storage traffic environments. This ToR switch features 48 x 25 GbE SFP28 ports, 4 x 100 GbE QSFP28 ports, and 2 x 100 GbE QFSP28-DD ports. The S5248F-ON switch also supports ONIE for zero-touch installation of network operating systems.

    See Dell EMC PowerSwitch S Series 10GbE Switches and Dell EMC PowerSwitch S Series 25/40/50/100 GbE Switches for more information about these switches.

    Note: Ensure that you comply with the switch requirements in the Dell EMC VxRail Network Planning Guide, which provides important information, recommendations, and best practices for VxRail appliances. Consider the same recommendations for vSAN Ready Nodes.

    Networking

    Designed for true linear scaling, VxRail appliances use a leaf-spine network architecture, which consists of two network tiers: an L2 leaf and an L3 spine that is based on 40 GbE and non-blocking switches. This architecture maintains consistent performance without any throughput reduction.
