Each of the VxRail management components you deploy in the VxRail cluster requires you to assign an IP address, and assign a fully qualified hostname. During initialization, each of these VxRail management components are assigned a hostname and IP address.
Determine the naming format for the hostnames to be applied to the required VxRail management components: each ESXi host, and VxRail Manager. If you deploy the vCenter Server in the VxRail cluster, that also requires a hostname. In addition, if you decide to deploy Log Insight in the VxRail cluster, that needs a hostname as well.
Note: You cannot easily change the hostnames and IP addresses of the VxRail management components after initial implementation.
