Network Design for SDDC Manager
You place SDDC Manager on the management VLAN for traffic segmentation, and decide on the IP addressing scheme and name resolution for optimal support for the SDDC management components, and host provisioning and life cycle management.
SDDC Manager Network Design
Network Segments
The SDDC Manager appliance is connected to the management VLAN for secure access to the application user interface and API.
IP Addressing
You must use statically-assigned IP address for the SDDC Manager appliance. Following industry best practices, VMware Cloud Foundation does not allow using DHCP to assign IP addresses to the management components.
Name Resolution
Name resolution provides the translation between an IP address and a fully qualified domain name (FQDN), which makes it easier to remember and connect to components across the VMware Cloud Foundation instance. Each IP address must have valid internal DNS registration which includes forward and reverse name resolution. The SDDC Manager appliance must maintain network connections to the following components:
- vCenter Server
- ESXi hosts
- NSX Manager cluster
- Internal DNS servers for name resolution of other management components
Time Synchronization
Time synchronization provided by the Network Time Protocol (NTP) is important to ensure that all components within the VMware Cloud Foundation instance are synchronized to the same time source. Configure the SDDC Manager appliance with time synchronization using an internal NTP time source.
