Issue/Introduction

The VMware Cloud Foundation (VCF) Management Domain is a foundational cluster designed for automated lifecycle management. This article describes the mandatory host and storage configurations required for the Management Domain.

Environment

VMware Cloud Foundation

Cause

The Management Domain architecture is strictly locked to vSAN storage during the initial Cloud Builder "bring-up" process. SDDC Manager automation, including patching and scaling, is hard-coded to enforce vSAN storage policies. Manual database modifications to bypass these storage constraints are not supported and risk corrupting the SDDC Manager inventory.

Resolution

For the Management Domain on the default cluster of a VMware Cloud Foundation environment, the minimum requirements are as follows:

 

Single Availability Zone (Standard vSAN cluster): 4 x ESXi hosts

Two Availability Zones (Stretched vSAN cluster): 8 x ESXi hosts (4 on each site.)

If non-vSAN storage (FC, NFS, or vVOL) is required for additional workloads, deploy a separate Workload Domain (VI WLD).

Non-vSAN clusters are not supported within the Management Domain.
