Pre-check Error: "The speed of vmnic# on host <hostname> is 1000 MB/s but must be at least 10 GB/s according to minimum hardware requirements." During VMware vSphere Foundation Deployment via VCF Installer

Products

• VMware vSphere Foundation

Issue/Introduction

When attempting to deploy a VMware vSphere Foundation (VVF) environment using the VCF Installer, the deployment fails during the pre-check phase if the ESX management network speed is less than 10 Gbps.
The following error is displayed:

"The speed of vmnic# on host <hostname> is 1000 MB/s but must be at least 10 GB/s according to minimum hardware requirements."

 

Environment

VMware vSphere Foundation 9.0
VCF Operations 9.0

Cause

The VCF Installer requires a minimum management network speed of 10 Gbps for all deployments, regardless of whether it is for VMware Cloud Foundation (VCF) or VVF.

Resolution

For VVF deployments where a 10 Gbps NIC is unavailable, you can manually deploy VCF Operations using the OVA file and then register the vCenter to complete the environment setup.

Getting Started with vSphere Foundation

Deploy VCF Operations Nodes

 

Important:

• This manual deployment method is only supported for vSphere Foundation (VVF) environments. It is not supported for VMware Cloud Foundation (VCF) deployments.
• Using 10 Gbps NICs for the management network is best practice, especially for vSAN. If you choose to use a lower speed, please ensure sufficient verification is performed before production use.
