A few weeks ago I saw a presentation from Trevor Davis about a Power App to generate an ARM template to help with quickly getting a customer started with deploying an AVS Private Cloud. Trevor did a great job making it easy for customers to deploy. Unfortunately the Power App was internal only and couldContinue reading “AVS ARM Template Generator”

There are plenty of posts telling you how to do packet captures on NSX-T. Most of them do a great job explaining where to take captures and what commands to run. If you read them you’ll see the number of commands to run and the number of places to run them are both large. IContinue reading “NSX-T Packet Captures”

Have you ever wanted to remove L2 between datacenter switches? I was talking with one of my friends Shakes and he was told by VMware that L2 was a must between TORs for ESXi to work if you had interfaces across the TORs. Well that seems to defeat the point of spine-leaf to me. AContinue reading “ESXi as a BGP Speaker”

Recently I was working on a script and need to access my local vCenter. I happened to be on a different network that needed to route to another network. This had been working fine but at some point a new VPN configuration got pushed to my machine. Normally I would just switch laptops but IContinue reading “VPN and Local Routes”

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”
