Happy New Year! 🙂 In the last two posts we had a look at two different methods for extending VLANs to NSX-T overlay. In the first post we configured a bridge which works well in scenarios where we the source VLAN and destination NSX-T Edge can achieve layer 2 adjacency. In the second post we…
In the previous article we had a look at how VLAN-connected workloads were migrated to NSX-T overlay by setting up a bridge between VLANs and NSX-T overlay segments. This works well in scenarios where layer 2 adjacency between source and destination environment can be achieved. In other words, we can stretch the source VLAN(s) to…
Organizations implementing NSX-T overlay have several options when it comes to migrating existing VLAN-connected workloads to NSX-T overlay segments. Common methods include re-IP’ing or re-deploying workloads to a new IP space allocated to NSX-T logical networking. It gives the workload somewhat of a fresh start. Besides, a re-IP process can be a very useful exercise…
Back in April I published a post about my GitHub repository containing Ansible scripts that perform automated deployment of nested vSphere/NSX-T lab environments. A lot has happened during the last 5 months and now that we’re close to making version 2 the default branch, I thought it would be a good time to give you…
And now something completely different. Recently, while working on a project, I had to come up with a way to automate Ubuntu Server 20.04 VM installations on vSphere. Utilizing Ubuntu’s new autoinstall method together with some Ansible code I managed to get something up and running. Decent enough to share it with you. Overview The…

Some weeks ago I introduced you to my GitHub repository containing a set of Ansible playbooks helping people deploy a highly customizable vSphere 6.7/7.0 with NSX-T 2.5/3.0 nested lab environment. As I mentioned in the “launch” post, this project is a work in progress and during the last couple of weeks I’ve been spending many…

Welcome back! I’m in the process of setting up NSX-T in a stretched cluster environment. In part 1 I deployed the NSX manager cluster and configured the ESXi hosts as NSX transport nodes. The N-VDS was installed on the ESXi hosts and their vmkernel adapters migrated from the VDS to the N-VDS. In this second…
A stretched cluster architecture facilitates for higher levels of availability and things like inter-site load balancing. It’s a common multisite solution and also part of VMware’s Validated Design for SDDCs with multiple availability zones. Traditionally compute networking in an active-active multisite setup has had its challenges, but with vSAN storage and NSX networking technologies that’s…
Welcome back! In part two we deployed the data plane for the East-West traffic in our cross-vCenter NSX environment. In this part we continue with the setting up the components for the North-South traffic. Current state A quick look at the current state of our cross-vCenter NSX lab environment. The management plane and the control…
One of those scenarios where the NSX platform really shines is in multi-site environments. Here NSX together with vSphere is the infrastructure that delivers on business requirements like workload mobility, resource pooling, and consistent security. Since NSX version 6.2 we can roll out NSX in a vSphere environment managed by more than one vCenter system.…
