A while ago I wrote a post about ICMP latency: https://vskeeball.com/2021/09/14/ping-is-not-a-real-latency-measurement/. While we all conceptually understand this I recently helped build a testing framework to show a few types of tests running from AVS to Azure Native. Actually seeing the data brought home the points from the last post. These tests were all run oneContinue reading “TCP/UDP vs ICMP Latency”

I recently had a question from a colleague about how to move the gateway for a layer 2 extended network in HCX. The move gateway operation in HCX forces you to unextend the network. This is fine if all the workloads on the segment have been migrated but the story I’ve always been told andContinue reading “NSX-T HCX or L2 VPN and VDR MAC”

I’ve gotten a lot of questions from customers about how to monitor their NSX-T edges in AVS. Since the edges are considered management components customer don’t get access to the edge VMs in AVS (or most other clouds). This is done to protect the customer from breaking their environment by accidentally doing something to theContinue reading “NSX-T Edge Interface Monitoring”

A few month ago I thought it would be nice to have a vSphere content library on blob store. I did some googling and found Trevor Davis had posted this: https://avs.ms/centralized-avs-content-library-on-azure-blob/. I read it and thought there has got to be a better way than making the library on my machine running William Lam’s scriptContinue reading “vSphere Content Library on Azure Blob”

There have been quite a few blog posts about third party firewalls or in Azure speak NVA (Network Virtual Appliance) in AVS. Why Azure calls these NVAs and not VNFs (Virtual Network Function) like the rest of the world is a question I’d like to have answered. While the DFW (Distributed Firewall) should be usedContinue reading “Third Party Firewalls in AVS”

I’ve had a few questions about 802.1q trunk ports over NSX-T overlay segments. Normally the question are around using a trunk port to connect a firewall VM to get around the 10 network interface limit on VMware VMs. Unfortunately that type of configuration has one major issue. The VMs being secured must do VLAN taggingContinue reading “NSX-T 802.1q Over Geneve”

I had an ask from a customer about how to set storage policies on multiple VMs in AVS. You can accomplish this via run commands as documented https://docs.microsoft.com/en-us/azure/azure-vmware/configure-storage-policy but the customer needed a little bit more flexibility in specifying multiple VMs to run the command against. The run command supports wild cards but that wasContinue reading “Multiple VM Storage Policies”

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”
