VCF 9.1 - Deploying VCF Management Services (VCFMS) with Custom IP Allocation using SDDC Manager API

by // Leave a Comment

One of the new steps when upgrading an existing VMware Cloud Foundation (VCF) 5.x or 9.0.x environment to VCF 9.1 is deploying the new VCF Management Services (VCFMS) component using SDDC Manager.


Unlike a brand new VCF 9.1 deployment using the VCF Installer, the VCFMS deployment workflow during an upgrade requires the VCF Services runtime network to be specified using a CIDR format rather than an IP Range, which can also be tricky if you do not have a contiguous IP address block.


Users can choose from additional IP allocation options, but you will need to use the SDDC Manager API, as I recently shared in this blog post.

To demonstrate this new SDDC Manager API, I have put together a quick PowerShell script called deploy_vcf_management_service_with_custom_ip_allocation.ps1 that simplifies the deployment of VCFMS using a custom IP allocation method.

VCF 9.1 - VCF Download Tool (VCFDT) Cheatsheet

by // 5 Comments

The latest release of VMware Cloud Foundation (VCF) Download Tool (VCFDT), which ships as part of VCF 9.1, includes a number of enhancements for downloading VVF and VCF installation and upgrade binaries.

For new users of VMware Cloud Foundation Download Tool (VCFDT), I thought it would be useful to put together a quick cheat sheet covering some of the most common workflows, ranging from configuring an activation code and downloading the required VCF 9.1 binaries for initial deployments and upgrades, to the new workflow for downloading ESX patches and updates.

I have even found myself repeatedly using the --help command just to locate a specific option or workflow, so hopefully this serves as a useful reference for both new and existing users, including myself! 😅

VCF 9.1 - Demystifying Supported Upgrade Paths to 9.1

by // 9 Comments

The rapid advancement of frontier AI capabilities, including recent developments from Anthropic Mythos, keeping software and infrastructure up to date has become a critical priority for many IT organizations.

VMware vSphere Foundation (VVF) and VMware Cloud Foundation 9.1 introduce a ton of powerful new private cloud capabilities, which has generated tremendous interest from both customers and partners, ranging from new deployments to modernizing existing environments, all with the goal of building a more secure and resilient private cloud platform while also helping address the rapidly evolving threat landscape.

One area that has significantly changed from earlier VCF releases prior to VCF 9.0 is around upgrades, which has been a major source of confusion, even for myself at times. I will not try to defend some of the confusion and misconceptions from the past, but I will say that VCF 9.1 introduces more flexible upgrade paths, allowing customers to take advantage of the latest capabilities while also meeting them where they are currently at in their Private Cloud journey.

With that said, I am hoping this quick blog post, along with some visuals, will help demystify the supported upgrade paths to VCF 9.1, including some of the common misconceptions around specific feature capabilities and future direction, especially as it relates to VCF Automation VM Apps (Traditional) and All Apps (Modern) or Networking using VLAN-backed, NSX Overlay/Segment and Modern NSX VPC.
