An administrator is preparing to import a vSphere environment into VMware Cloud Foundation (VCF) as a workload domain. The vSphere environment has…

VMware Cloud Foundation (VCF) requires static IP addresses for all ESXi host vmkernel adapters, including those for management, vSAN, and vMotion. The SDDC Manager, which automates the deployment and lifecycle management of the software-defined data center, relies on these predictable, static addresses for all its workflows. Using DHCP for these critical infrastructure interfaces introduces network instability and unpredictability, which is unsupported and would cause the import and subsequent management operations to fail. Therefore, the administrator must reconfigure the vmkernel adapters from DHCP to use statically assigned IP addresses before importing the cluster into VCF.

A. VCF supports importing and managing clusters that use multiple vSphere Distributed Switches; consolidation into a single VDS is not a prerequisite.
B. vSphere 9.0 is not a released product. VMware Cloud Foundation 5.x is compatible with vSphere 8.0, so no version upgrade is necessary.
D. VCF supports clusters using either vSAN Original Storage Architecture (OSA) or Express Storage Architecture (ESA). Conversion from OSA is not required for import. ---

1. VMware Cloud Foundation 5.1 Administration Guide, "Prerequisites for Using a vSphere Cluster for a VI Workload Domain", Page 101.

The "Host Requirements" table explicitly states: "The management VMkernel adapter on each ESXi host must be configured with a static IPv4 address." and "The vSAN and vMotion VMkernel adapters on each ESXi host must be configured with static IPv4 addresses." This directly confirms that static IPs are mandatory.

2. VMware Cloud Foundation 5.1 Planning and Preparation Guide, "Network Requirements for a vSphere Cluster for a VI Workload Domain", Page 36.

This section details the networking prerequisites for hosts that will be part of a VI workload domain, reinforcing the requirement for static IP addressing for all infrastructure traffic (Management, vSAN, vMotion). It notes, "Each ESXi host in the cluster must have a static IP address assigned to its management network VMkernel adapter."

3. VMware Cloud Foundation Architecture and Design Guide, "Workload Domain Network Architecture", Section 3.2.3.

This guide outlines the fundamental design principles of VCF networking. It describes the management, vSAN, and vMotion networks as core infrastructure components that require stable and predictable IP addressing, which is achieved through static assignment, not DHCP.
