Appendix A: VxRail Network Configuration Table

  • The Dell service representative uses a data collection workbook to capture the settings that are required to build the VxRail cluster. The workbook includes the following information:

    Table 41. Data collection workbook content
    Row Topic Category Description
    1 VxRail Networks External Management VLAN Untagged traffic is recommended on the Native VLAN. If you want the host to send only tagged frames, manually configure the VLAN on each ESXi host using DCUI and set tagging for your management VLAN on your switch before you deploy VxRail.
    2 Internal Management VLAN This network traffic should stay isolated on the ToR switches. The default VLAN ID is 3939.
    3 vMotion VLAN VMware vSphere vMotion VLAN
    4 vSAN VLAN VMware vSAN VLAN
    5 Guest Networks VLAN Network name
    6 VLAN
    7 VMware vCenter Server Management VLAN VMware vCenter Server network on the same VLAN as external management network by default. Can also be assigned a unique VLAN.
    8 External Management Network Settings Subnet Mask Subnet mask for VxRail External Management Network
    9 Default Gateway Default gateway for VxRail External Management Network
    10 VMware vCenter Server Management Network Subnet Mask VMware vCenter Server network on the same subnet as external management network by default. Can optionally be assigned a new subnet mask.
    11 Gateway VMware vCenter Server network on the same subnet as external management network by default. Can optionally be assigned a new gateway.
