How to create a vSAN Cluster is a step-by-step guide that explains the main concepts behind VMware vSAN and the required steps to build a functional vSAN environment. This article covers how vSAN works, how storage is distributed across ESXi hosts, and the initial configuration process. VMware vSAN is a software-defined storage platform integrated with VMware vSphere that combines local disks from multiple ESXi hosts to create a shared distributed datastore. Because all storage traffic depends on the vSAN network, proper planning of hardware, disks, and network connectivity is essential. In this tutorial, we will create a vSAN Cluster in…

Applying a patch on an ESXi host is an essential maintenance task for keeping VMware environments updated and stable. This guide explains how to update an ESXi host using the Command Line Interface (CLI) and a patch bundle file. VMware provides different methods to patch ESXi hosts, but in this tutorial we will focus on the CLI-based approach. This method gives administrators direct control over the update process and is commonly used in controlled maintenance scenarios. Before starting the patching procedure, it is important to verify the current ESXi version, download the correct patch file, and schedule the maintenance activity.…

Configuring vCenter Server HA is a practical guide that explains how to implement High Availability for VMware vCenter Server environments. This feature helps protect the vCenter Server management platform by using additional nodes to provide availability during failures. The vCenter Server is a critical component in a vSphere environment, responsible for managing and configuring cluster resources. Without High Availability, recovering an unavailable vCenter Server instance can require additional time and manual intervention. In this tutorial, we will configure vCenter Server HA by creating the required network configuration and deploying the Active, Passive, and Witness nodes. The process covers the HA…

Applying a patch on the vCenter Server is an essential maintenance task to keep VMware environments updated, secure, and running with the latest fixes. This guide explains how to update vCenter Server using the Command Line Interface (CLI) and a patch ISO file. There are different methods available to update vCenter Server, but in this article we will focus on the CLI-based approach. This process allows administrators to stage and install the patch directly from the vCenter Server Appliance environment. Before starting the patching procedure, it is important to verify the current vCenter Server version, review the available patch release,…

Configuring CentOS 7 Network is a practical guide that explains how to configure network interfaces in a CentOS 7 system. This article covers the process of obtaining IP settings automatically through DHCP and configuring a static IP address manually. CentOS 7 uses predictable network interface names instead of the traditional eth0 naming convention found in older Linux distributions. Understanding these interface names is essential when modifying network configuration files and troubleshooting connectivity issues. In this tutorial, we will configure the network interface on a CentOS 7 virtual machine, showing how to identify the correct interface, edit network configuration files, restart…

How to install vCenter 8 is a step-by-step guide that explains how to deploy the vCenter Server Appliance in a laboratory environment using VMware Workstation. Although vCenter 8 is not fully homologated for this platform, this article demonstrates a practical approach to complete the installation process. The installation process for vCenter 8 is very similar to previous versions, but some additional adjustments may be required when running the appliance in VMware Workstation. During testing in our lab environment, an error occurred during Stage 2 of the deployment process. In this tutorial, we will show how to install vCenter 8 in…
