Upgrade from vSphere 8.x to 9.1

This blogpost describes the upgrade from vSphere 8.x to 9.1. Why would someone go this route or VVF and not VCF you might ask? Well, even large customers have smaller environments that are (needs to be) completely disconnected from the main site. Note that even in most of these scenarios a VCF Edge design would be a perfect solution. See...

Cannot login user root@127.0.0.1: no permission

If you are running vSphere environments you will probably recognize this vCenter warning and log-entry that is flooding your (log)server-logs. Luckily I was working with a customer that did not accept the default answer as mentioned in this KB. Therefor I investigated the issue and found several causes for this error to occur.

VMware Cloud Foundation 9 Offline Depot Installation and configuration

Introduction For dark / disconnected VCF Deployments it has been quite a challenge for some time to import files to SDDC Manager and vRSLCM. This changed with the Offline Depot introduction in VCF 5.2 and got even better with VMware Cloud Foundation 9. In this release you can setup a Unified Offline Depot, hosting the install and update files for...

VMware VCF Offline Depot Certificates

Recently I have been doing some VCF 9 deployments in my homelab environment and I am using an VCF9 offline depot to keep the environment as close as possible to any customer environment. For now, I will not go into the details of installating and configure the offline depot webserver, since there have been various blogs about this topic. (Perhaps...

vSphere Memory Tiering with Asus Hyper M.2 X16 for nested VCF 9

As written in the previous blog, I was quite satisfied with my homelab setup. It doesn’t take to much space, is low noise and has enough resources and performance to run a Nested VCF 5 setup. With the release of VCF 9, I am still able to run a basic setup, but with the additional VCF Automation and Supervisor components,...

My VMware homelab setup

In my role as TAM at VMware by Broadcom, I find it very useful to have a self managed homelab environment. Although I have several options available internally, it does not always provide the full access and/or flexibility. My homelab should be cost effective, but powerful enough to deploy a (nested) VMware Cloud Foundation (VCF) 5 (at the time of...
