Shut Down the vSAN Cluster is a practical guide that explains how to correctly power off a VMware vSAN environment during scheduled maintenance activities. The article demonstrates the shutdown procedure using the vSAN Cluster Shutdown Wizard available in vSAN 7.0 Update 3 and later versions. The vSAN Cluster Shutdown Wizard simplifies the process by automating several required tasks before powering off the cluster. For older vSAN versions where this wizard is not available, additional manual steps are required to complete the shutdown process safely. In this article, we will show step-by-step how to apply the vSAN Cluster Shutdown procedure in…

Adding hosts into an existing vSAN Cluster is a practical guide that explains how to expand a VMware vSAN environment by introducing new ESXi hosts with minimal impact. In this example, we are working with a vSAN Stretched Cluster and will demonstrate the required steps to add additional hosts and integrate them into the existing infrastructure. Before adding new hosts, it is important to understand the current vSAN Cluster configuration, including the existing ESXi hosts, Witness Appliance, network configuration, and available datastore capacity. These details help ensure that the new hosts are added correctly and follow the existing cluster design.…

Creating a vSAN Stretched Cluster with vSAN 8 is a practical guide that explains how to configure a Stretched Cluster using the new vSAN Express Storage Architecture (ESA). This article demonstrates the required steps to implement a vSAN 8 Stretched Cluster in a lab environment, including the main components and configuration process. vSAN 8 introduced the Express Storage Architecture (ESA), a new optional storage architecture designed to take advantage of modern hardware capabilities while improving performance, scalability, resilience, and data services. ESA works alongside the traditional vSAN Original Storage Architecture (OSA), allowing administrators to choose the most suitable architecture for…

Creating a vSAN Stretched Cluster is a practical guide that explains how to deploy a VMware vSAN configuration designed for environments that require higher availability and protection against site failures. This article covers the main concepts and the steps required to build this type of cluster. A vSAN Stretched Cluster extends storage availability across two data sites with the support of a Witness Host or Witness Appliance. This architecture allows workloads to continue operating even when one of the data sites becomes unavailable, depending on the configured policies and environment design. In this tutorial, we will explore how a vSAN…

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.…
