Creating stretched networks with NSX-T Federation

Creating stretched networks with NSX-T Federation

After the initial configuration and setup of NSX-T local and global managers ├índ setting up layer-3 communication (see previous blogs), we can go for the real new thing of NSX-T 3.0, stretched networking with Federation. We are aiming for the following setup: In order to set this up, we need Edge Nodes on both sites (we have those) and a configuration of Remote Tunnel Endpoints (RTEPs). We also need to create a stretched T0 and T1 and setup BGP to…

Setting up layer-3 connectivity with NSX-T

Setting up layer-3 connectivity with NSX-T

After the installation (https://my-sddc.net/nsx-t-global-manager-installation-and-initial-setup/) and initial configuration (https://my-sddc.net/nsx-t-3-0-initial-configuration/), we can start building networks. In order to get connectivity from the virtual network to the physical network, we need to setup layer-3 connectivity. In order to be able to do that, I bought a small Mikrotik device, to allow me to play around with BGP/BFD and VRF’s. What we need to do to get layer-3 connectivity is: Create transport zones for transit networks Create an uplink profile for edge nodes Setup…

NSX-T 3.0 – Initial Configuration

NSX-T 3.0 – Initial Configuration

This blog is to describe the initial configuration of NSX-T 3.0. After deploying the appliances and combining them into one environment (https://my-sddc.net/nsx-t-global-manager-installation-and-initial-setup/) and deploying the vSphere/vSAN environment (https://my-sddc.net/building-the-lab-vsphere-and-vsan/) it is time to combine the two and create the virtual network environment. As a reminder, our environment is going to look like this: but that’s mainly the physical side of it. The virtual side is still something I have to figure out, but for now, it’s roughly going to look like…

NSX-T Global Manager installation and initial setup

NSX-T Global Manager installation and initial setup

In my new lab environment, I will be working with two locations (Site A and Site B) and a Global NSX-T Manager to centrally manage the environment. For this, I installed a Global Manager after I deployed both Local Managers. Since I am not made of resources, all sites and the global environment will consist of one appliance, but in a production environment you would definitely need three per function. The installation of the Global Manager is almost identical to…

New Lab – Part 2 – Setup and some small tips & tricks

New Lab – Part 2 – Setup and some small tips & tricks

For my lab environment I am building on a combination of physical and virtual. I have one (massive, from home lab perspective) DL380 on which I will run multiple nested environments and I have one PC with a fair amount of memory, which will host some virtual machines, that will help me along. Setup Basically, I am working towards the following setup (for now): All of this is connected to a NetGear switch (not to fancy, but support for VLAN’s…

Upgrading the demo environment, with vSphere 7 and NSX-T 3

Upgrading the demo environment, with vSphere 7 and NSX-T 3

After the release of NSX-T 3.0, nothing stands in the way of upgrading our demo environment to NSX-T 3.0, making it ready for vSphere 7. Because I wanted to see the checks in the upgrade process of vSphere 7, where it will inform you of the interoperability of NSX-T, I started with the upgrade of the vCenter Server: and choosing Upgrade. After following the wizard a new appliance is deployed. This appliance will then be used to upgrade the current…

Checking environment after migration NSX V to T and cleanup

Checking environment after migration NSX V to T and cleanup

Earlier I wrote a post on the migration between NSX for vSphere (NSX-V) and NSX-T (https://my-sddc.net/migrate-nsx-for-vsphere-to-nsx-t/) . I stopped after the migration was complete because the post was long enough already and promised to come back with an article on the environment and clean up afterward. This is that article as you might have expected ;). Checking and repairing the environment So, after the migration, I found out a couple of things that I had to “repair”. They are all…

Migrate NSX for vSphere to NSX-T

Migrate NSX for vSphere to NSX-T

As you might know, I use a test/demo environment from my employer. In this environment, I can demo the VMware SDDC products for customers or colleagues. Since the start of the environment approx. four years ago, I had a demo around NSX for vSphere, but as you know, the product has been announced to go end of support in 2022 and there will be no more development on it. Also, VMware and my company (PQR) advise customers who start on…

Remove first NSX-T Manager from the cluster, manually

Remove first NSX-T Manager from the cluster, manually

I need to remove my first NSX-T Manager that I deployed in my test-environment. With other managers, you get the (easy) ability to do so from the GUI: But not for the one that was deployed as the first one in the cluster: (the option is missing). But it is still possible to do this. We need to manually detach the manager from the cluster, which can be done from one of the other managers. We log in to one…

Upgrade of NSX-T with VCF: “Disk Space requirements not met”: Failed upgrade

Upgrade of NSX-T with VCF: “Disk Space requirements not met”: Failed upgrade

A short post on (part of) the upgrade of NSX-T from within VCF, since this is not the first time I ran into this. It is most likely related to the fact that I run a nested ESXi environment, but someone else might run into the same issue. The biggest problem occurs when upgrading NSX-T as part of the VCF upgrade process. What happens when upgrading NSX-T manually is that you run a PreCheck. This will tell you if everything…
