NSX Manager deployment steps is the first step when building an NSX-T Data Center environment. In this guide, we will demonstrate how to deploy the first NSX Manager appliance from an OVA file and configure the required settings for initial access. The deployment process is performed through VMware vCenter Server using the OVF Template wizard. During this procedure, we will configure the virtual machine size, storage location, management network, authentication settings, and network parameters required by the NSX Manager appliance. After completing the OVA deployment and powering on the appliance, the NSX Manager services need some time to initialize. Once…

VMware NSX-T is a software-defined networking (SDN) platform designed to virtualize and automate network and security services in modern data center environments. In this article, we will explore the basic concepts of NSX-T, its architecture, and the main components that build this solution. NSX-T abstracts traditional network components such as switches, routers, firewalls, VPNs, and load balancers into software-based services. This approach allows organizations to apply consistent security and networking policies across virtualized environments while improving agility and operational efficiency. This article, Introduction to NSX-T, will provide the basics and fundamental details of NSX-T. Update: Nowadays, VMware has changed the…

Introduction to SDDC (Software Defined Data Center) is a concept that transforms traditional data center infrastructure by using software-based technologies to manage computing, storage, and networking resources. In this article, we will explore the core fundamentals of SDDC and understand how virtualization enables more flexible and scalable environments. SDDC is widely used in modern data center architectures, especially in private, public, and hybrid cloud environments. By abstracting hardware resources through software layers, organizations can create resource pools that improve utilization, automation, and operational efficiency. An SDDC infrastructure is based on three main virtualization layers: compute, storage, and networking. These layers…

Installing KVM on Ubuntu 22.02 allows Linux systems to work as virtualization hosts capable of running multiple virtual machines. In this guide, we will show how to install and configure KVM packages, prepare the network environment, and create a virtual machine using the graphical management interface. The procedure was performed on Ubuntu 22.02 Desktop Edition running as a nested virtual machine inside VMware Fusion. To enable KVM functionality in this scenario, nested virtualization support must be activated in the hypervisor configuration before installing the required packages. Kernel-Based Virtual Machine (KVM) is an open-source virtualization technology integrated into the Linux kernel.…

Updating vCenter Server 6.7 to 7 requires careful planning, especially in production environments where availability and configuration integrity are critical. In this guide, we will demonstrate the complete upgrade process, including backup preparation, new vCenter Server deployment, and migration steps. In our lab environment, we are using a vCenter Server 6.7 installation with Embedded PSC running on an ESXi host. Before starting the upgrade, we will create a manual clone of the existing vCenter Server virtual machine to ensure a recovery option is available in case any issue occurs during the migration process. The upgrade process from vCenter Server 6.7…

Requesting a Certificate for an Internal CA is a practical guide that explains how to submit a Certificate Signing Request (CSR) file to an internal Certificate Authority. In this lab environment, we are using Microsoft Active Directory Certificate Services (AD CS) running on Windows Server to issue the certificate. Before requesting the certificate, it is necessary to have a valid CSR file generated with the required certificate details. The CSR contains the information that will be used by the Internal CA to generate and sign the final certificate. In this article, we will demonstrate step-by-step how to access the CA…
