Before deploying the vCenter server, a DNS server must be available on the network. Dell Technologies recommends the use of an NTP server as all hosts and vCenter need to have their times synchronized for VMware Skyline Health checks to pass. In this section, a VM used as the DNS/NTP server is deployed.
- From the jump host, connect to the ESXi services host UI in a browser, https://192.168.11.5 in this example, and log in as root.
- Select Virtual Machines > Create/Register VM.
- Choose one of the methods provided to deploy the virtual machine. Note: Steps to deploy the virtual machine depend on the method used and are outside the scope of this guide. See your VMware vSphere documentation for more information.
The VM in this example is named win-dns, as shown. In the vSwitch, ensure the port group the VM is connected to is in the management VLAN, VLAN 11 in this example. Also ensure the physical adapters match those connected to the leaf switches, vmnic2 and vmnic3 in this example.
- Log in to the VM’s operating system and configure the IP address, subnet mask, and gateway. Note: This example uses 192.168.11.1, 255.255.255.0, and 192.168.11.254 respectively.
- Verify that the VM can ping ESXi hosts in all sites by their IP addresses.
