VxRail depends specific applications in your data center to be available over your data center network. These data center applications must be accessible to the VxRail management network.
A time zone is required. It is configured on vCenter server and each ESXi host during VxRail initial configuration.
Dell Technologies recommends that you provide an NTP server but it is not required. If you provide an NTP server, vCenter server is configured to use it. If you do not provide at least one NTP server, VxRail uses the time that is set on ESXi host number 1. This time is set regardless of whether it is correct.
Note: Ensure that the NTP IP address is accessible from the VxRail External Management Network to which the VxRail nodes connect and is functioning properly.

Starting with VxRail version 7.0.010, you can either use an internal DNS included with VxRail vCenter Server or an external DNS in your data center. If you choose to use the internal DNS method, the steps to set up DNS as outlined in this section can be skipped.
If the internal DNS option is not selected, one or more external, customer-supplied DNS servers are required for VxRail. The DNS server that you select for VxRail must be able to support naming services for all the VxRail management components (VxRail Manager, vCenter, and so on).
Note: Ensure that the DNS IP address is accessible from the network to which VxRail Manager is connected and is functioning properly.

|Enter the IP addresses for your DNS servers.|
Create lookup records in your selected DNS for every VxRail management component that you deploy in the cluster and assign a hostname and IP address. These components can include VxRail Manager, VxRail vCenter Server, VxRail Platform Service Controller, Log Insight, and each ESXi host in the VxRail cluster. The DNS entries must support both forward and reverse lookups.
Use Appendix A: VxRail Network Configuration Table to determine which VxRail management components to include in your planned VxRail cluster. Ensure that you have assigned a hostname and IP address. vMotion and vSAN IP addresses do not require hostnames, so no entries are required in the DNS server.
