Have you finished your cloud migration and need to remove or uninstall HCX? VMware has a nice KB on how to do this. https://docs.vmware.com/en/VMware-HCX/4.2/hcx-user-guide/GUID-28172DB0-93C6-4A7A-B5A9-51C8325B02DC.html. Basically make sure all replications are finished, unextend any networks, delete any service meshes, delete the site pairing, power off the connector appliance, delete it, and unregister the extensions. Seems easyContinue reading “HCX Removal”

Have you ever wanted to use the NSX-T load balancer to provide access to resources outside of NSX-T? This sounds easy enough but the routing of the outside network stack may cause some issues. A diagram helps here: In this example when the external client accesses a load balancer or DNAT on the T1 directedContinue reading “NSX-T Load Balancer With External Devices”

While I was talking to my new teammates at Microsoft here in the AVS (Azure VMware Solution) team about some ideas the team had for things we could do I came up with a neat experiment. Can I vMotion a VM from an AVS Cloud to my car? Some people ask why. I ask whyContinue reading “vMotion to a moving Car”

So we all know that you write VMware with a capital VM and lower case ware. At least you know now. I was talking with a co-worker today and they mentioned that it made them twitch when it wasn’t right. Now don’t get me wrong here I’m particular about a lot of things. As myContinue reading “VMware Capitalization”

Customer says “I need XXms latency.” What do you do? Break out the command line and ping from server A to server B. Numbers below what they asked for? Great. What happens when it’s higher than they need? I have a customer that is asking for less than 0.2 ms of latency between two WindowsContinue reading “Ping is not a real latency measurement”

I often hear about NUMA and it’s performance implications. I even speak about it when people ask me about best practices. I never really had any numbers or proof that it was in fact a major performance issue until recently. Some of you may know that my main PC is a VM running on anContinue reading “NUMA and Gaming Performance”

One of my clients who has TAM services was trying to run the TAM Insights script to provide their TAM with some data. This script can take some time to run and must be run against each vCenter. For compliance purposes this client cannot have an idle session on their terminal servers used to accessContinue reading “TAM Insights and K8s”

Following up on my post about vCenter Certificate Replacement. I needed a scheduled way to update the certificate so I didn’t forget again and end up in the mess I was in to begin with. This turned out to be very simple. First I had to download the certificate from the load balancer again usingContinue reading “Certificate Replacement on vCenter: Part 2”

I was looking at my Raspberry Pi 4 the other day thinking of new uses for it. I thought I’d try to build a thin client. I went out to the VMware Horizon View Client download page and pulled down the latest Linux tarball. The tarball has an armhf directory and I thought “great! ThisContinue reading “Horizon Client on Pi4”

I use a Let’s Encrypt certificate on my VCSA. It validates and give me a pretty padlock in my address bar. Generally I use a wildcard cert for all my services but vCenter wont take that. So I have a “regular” server certificate for vCenter. As with all Let’s Encrypt certificates it expires regularly. ThisContinue reading “Certificate Replacement on vCenter”
