Some Examples of NSX Topologies show some topologies that can be used in the NSX environment. Firstly, I would like to share some documents related to the NSX Design Guide. You can check more details on these links if you prefer:https://nsx.techzone.vmware.com/resource/nsx-reference-design-guidehttps://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/products/nsx/vmw-nsx-network-virtualization-design-guide.pdf Single-Tier Topology/Deployment On this topology, we only have the Tier-0 gateway.All NSX Segments (Virtual Switches) are connected directly to the Tier-0 gateway. As we can see in the below picture, the Tier-0 gateway is responsible for connecting the virtual network (inside the NSX) to the physical network (outside the NSX). Furthermore, all Segments are connected to the Tier-0 gateway:…

Creating an Edge Cluster shows how we can create an Edge Cluster to use in the NSX environment. Creating an NSX Edge Cluster is an important step when building an NSX environment because it allows multiple Edge Transport Nodes to work together. This article demonstrates how to create an Edge Cluster after deploying the required Edge Transport Nodes. Before we start, I would like to share an article that we have written about all the steps necessary to deploy an Edge Transport Node:https://dpcvirtualtips.com/deploying-an-edge-transport-node/ What is an Edge Cluster? First and foremost, an Edge Transport Node is a component that resides…

Deploying an Edge Transport Node is an article that shows all the necessary steps to deploy an NSX Edge Transport Node. We are deploying an Edge VM (Virtual Machine) format in this example. We had written an article to explain basic concepts around the NSX. Access the below link to access this article:https://dpcvirtualtips.com/introduction-to-nsx-t/ What is an Edge Transport Node? Basically, an Edge Transport Node is a component of the NSX infrastructure. The Edge Transport Node resides on the NSX Data Plane and hosts the NSX gateways Tier-0 and Tier-1. Additionally, some services that cannot be distributed under the Host Transport…

This provoking question “Do you know how systemd-resolved works on the vCenter Server?” aims to show, in a basic way, how the daemon “systemd-resolved” works on the vCenter Server. This article explains how systemd-resolved works on the vCenter Server Appliance and shows the basic concepts behind this service. Understanding how DNS resolution is handled internally can help administrators troubleshoot name resolution issues in VMware environments. The systemd-resolved service is responsible for providing network name resolution to local applications. It works as a local DNS resolver, using configured DNS servers and maintaining information to process name resolution requests efficiently. In this…

Upgrading vCenter 7 to vCenter 8 is an article that shows, step by step, how to migrate the vCenter Server from version 7 to version 8. In our lab environment, we are using the following vCenter Server versions: From: vCenter Server 7.0 Update 3n (version 7.0.3.01600, build 21958406)To: vCenter Server 8.0 Update 2 (version 8.0.2.00000, build 22385739) Source: https://kb.vmware.com/s/article/2143838 Before Anything The upgrade process is a straightforward task. But, risks are involved and you need to be prepared to handle some problems and situations. We highly recommend you have a valid backup of the current vCenter Server. Additionally, you can…

Restoring a vCenter Server through backup is an essential recovery procedure that helps administrators bring back a vCenter Server Appliance using a valid file-based backup. This article demonstrates the complete restore process, from deploying a new vCenter Server Appliance to recovering the backed-up data. Before starting the restore operation, it is important to have a properly configured backup schedule on the vCenter Server. Without a valid file-based backup, this recovery method cannot be performed. VMware provides this backup approach to protect the vCenter configuration and data. In this example, we will use an existing vCenter Server backup to demonstrate how…
