Dell VxRail Network Planning Guide

Reserve IPv4/IPv6 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 VMware ESXi host in the VxRail cluster, if vSAN is the primary storage that is 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.

From VxRail 7.0.010 and later, you can choose to have the IP addresses assigned automatically during the VxRail initial build, or manually select the IP addresses for each ESXi host. If the VxRail version is earlier than 7.0.010, the auto-assignment method by VxRail is the only option. For the auto-assignment method, the IPaddresses 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 IPv4/IPv6 address auto-assignment method, record the IP address range.

For the manual assignment method, record the IPv4/IPv6 addresses.

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