Witness host initial configuration

  • In this deployment example, the ESXi witness host is connected to the DCI-Site-3 switch, as shown.

    Figure 38. Witness host management network connections

    Note: The witness host must be running the same ESXi version as the vSAN cluster hosts.

    For initial configuration, you can use a workstation to connect to the iDRAC virtual console of the witness host over the OOB management network.

    In the ESXi DCUI, the witness host is configured using the values shown in the table below. The vmnics shown are connected to the DCI-Site-3 switch in this deployment example. Your vmnic numbers may vary. The IP addresses and VLAN are from the planning data in Table 2.
