Updated Inventory & Calculator Scripts for counting Cores/TiBs for VMware Cloud Foundation (VCF) and VMware vSphere Foundation (VVF)

by // 11 Comments

Here are two new tools to help our users understand and calculate the required subscription capacity for the new VMware Cloud Foundation (VCF) and VMware vSphere Foundation (VVF) offerings, which are licensed based on physical CPU Cores for compute and total raw physical storage (TiBs) for vSAN.

Inventory Script

The PowerCLI script provided in KB 95927 is designed to help users inventory their existing vSphere environment (read-only account is sufficient) to assess the required VCF or VVF subscription capacity for compute and/or vSAN. The script has also been enhanced to incorporate the upcoming 100GiBs of vSAN storage entitlement for each VVF core that is provisioned to a vSAN cluster as well as the latest pricing and packaging for both VCF and VVF. For more details on how to download and use the inventory script, please check out the KB for more information.

Note: Make sure you are using the latest version of the script which had a minor update on 02/14/2024

Calculator Script

The PowerShell script provided in KB 96426 is designed to help users run different simulations for calculating the required VCF or VVF subscription capacity for compute and/or vSAN, especially in planning for a new or greenfield deployment. For customers who can not run the inventory script from KB 95927 due to organizational policies, the calculator script can be a viable alternative as long as you can manually provide the required parameters via the CSV input file used by the script. For more details on how to download and use the calculator script, please check out the KB for more information.


If you still have questions or require further assistance on sizing or pricing (including all applicable discounts), please reach out to your local VMware account team and they will be more than happy to help.

Automating certificate-manager CLI operations in vCenter Server (VCSA)

by // 3 Comments

I recently had a customer inquiry where they were interested in automating the certificate replacement for vCenter Solution Users when using the /usr/lib/vmware-vmca/bin/certificate-manager CLI, which is found within the vCenter Server Appliance (VCSA).


Note: One important thing to understand is that with vSphere 7.0, the vCenter Solution User certificates have been deprecated and the ability to replace the internal certificates will be removed in a future release as mentioned in the referenced vSphere blog post.

VMware does not recommend replacing the internal vCenter Solution User certificates, but for users who may have an organization requirement to do so, the operation is performed interactively using the certificate-manager CLI as mentioned earlier.

By design, the certificate-manager is meant to be consumed interactively and any non-interactive or automated use cases is not possible ...

Retrieving detailed vSphere Lifecycle Manager (vLCM) Image information from vSphere Cluster using PowerCLI

by // Leave a Comment

As more and more users are adopting vSphere Lifecycle Manager (vLCM) to simplify the lifecycle and configuration management of their ESXi hosts, you may want to get more information about a given vLCM image that has been associated with a specific vSphere Cluster.

While you can certainly get this information using the vSphere UI, you can also get this detailed information by using the vLCM REST API, which can easily be consumed using variety of vSphere SDK Clients including PowerCLI.

For inventory and/or auditing purposes, automation is typically the answer, especially at scale. I will not bore you with the details, but I recently created the following PowerCLI function called Get-vLCMClusterImageInformation and given the name of a vLCM-enabled vSphere Cluster, it will provide you with the associated ESXi base image and all Solutions and Components that is associated with a given image.

UPDATE (02/06/25) - The script has also been updated to also include information for a vLCM image that has integrated with an Hardware Support Manager (HSM) to provide firmware information.
