First steps into VCDX6-NV Wow! This has been quite a journey. After I achieved my first VCDX on DCV, I was pretty soon looking at the VCDX6-NV blueprint and quietly developed the ambition of shooting for the double. I’m in the luxury position of working at ITQ so I didn’t have to convince anyone at ...
After upgrading to vRealize Operations Manager 7.5, my next task at hand was upgrading to vRealize Network Insight (vRNI) 4.1. I’m really looking forward to this release because it supports VMware Enterprise PKS and Kubernetes as a data source. Very cool! vRNI 4.1 What’s New! Martijn Smit recently made the move to the vRealize Network ...

I’m running a fully nested homelab with a four-node vSAN Cluster. When trying to patch my vSphere environment using VMware Update Manager (VUM), my remediation pre-check fails because the vSAN Health Services are reporting an error. This short blogpost explains how to silence a vSAN Health Check: Since the ESXi servers are nested VMs, the ...

Manually deleting these NSX-T objects using the GUI is prohibited because these objects are supposed to be managed by PKS and are ...
UPDATE: I received some feedback on this blogpost from some of my ITQ colleagues. I should point out this is a very quick and dirty approach suitable for my homelab environment because it not only deletes the failed PKS cluster, but also the PKS deployment itself. This is easily fixed by Bosh by applying changes ...
Introduction In my homelab, I’m currently running a fully nested VMware environment in a single box. With the necessary tweaking and tuning, and thanks to fast NVME SSD storage, I can quite comfortably run 6 ESXi hosts concurrently. 4 Nodes with vSAN are running the management cluster (non-stop), and two 2-node clusters with NFS storage (provided ...
This is just a quick blogpost on a small issue I encountered during a VMware Validated Design (VVD) deployment. As part of the VVD deployment, all ESXi hosts need to be added to Active Directory. This allows for Role-Based Access Control (RBAC) over the ESXi hosts.. Following the planning and preparation guidelines, the customer nicely ...
