Reserve IP addresses for VxRail vSAN network

Reserve IP addresses for VxRail vSAN network

  • You can skip this section if your plans do not include configuring vSAN as the primary storage for your VxRail cluster.

    An IP address is required for the vSAN network for each ESXi host in the VxRail cluster, if vSAN is the primary storage planned for the cluster. A private address range is acceptable unless you decide you may expand beyond one rack and want to use a different subnet for the expansion racks.

    Starting with VxRail version 7.0.010, you can choose to have the IP addresses assigned automatically during VxRail initial build, or manually select the IP addresses for each ESXi host. If the VxRail version is earlier than 7.0.010, auto-assignment method by VxRail is the only option.

    For the auto-assign method, the IP addresses for the initial build of the VxRail cluster must be contiguous, with the specified range in a sequential order. The IP address range must be large enough to cover the number of ESXi hosts planned for the VxRail cluster. A larger IP address range can be specified to cover for planned expansion.

    For the IP address auto-assignment method, record the IP address range.

    Network Configuration Table

    Action

    Rows 56 and 57

    Enter the starting and ending IP addresses for vSAN.

    For the manual assignment method, record the IP addresses.

    Network Configuration Table

    Action

    Rows 58-61

    Enter the IP addresses for vSAN.

    Enter the subnet mask and gateway for the vSAN network. You can use the default gateway assigned to the VxRail External Management network if you do not need to enable routing for this network, or enter a gateway to enable routing for the vSAN network.

    Network Configuration Table

    Action

    Row 62

    Enter the subnet mask for vSAN.

    Row 63

    Enter the gateway for vSAN. The default gateway can be updated if routing is required.
