Dell VxRail Network Planning Guide

Confirm your firewall settings

If there is a firewall between the switches for VxRail and the rest of your data center network, verify that the required firewall ports are open for VxRail network traffic.

1. Verify that VxRail can communicate with the following:
   • DNS server
   • NTP server, if planned for clock synchronization.
   • Syslog server if you plan to capture logging.
2. Verify that your IT administrators can communicate with the VxRail management system.
3. For a customer-managed VMware vCenter Server, verify open communication between the VMware vCenter Server instance and the VxRail managed hosts.
4. To use a third-party syslog server instead of Log Insight, verify that open communication between the syslog server and the VxRail management components.
5. To deploy a separate network for ESXi host management (iDRAC), verify that your IT administrators can communicate with the iDRAC network.
6. To use an external secure connect gateway in your data center instead of the secure connection deployed in the VxRail cluster, verify the open communications between VxRail management and the secure connect gateway.
7. To use VMware subscription licenses with VxRail, confirm connectivity to the VMware Cloud from the VMware vCenter Cloud Gateway.
