Creating a Certificate Request with OpenSSL is a practical guide that explains how to generate a CSR (Certificate Signing Request) and private key using OpenSSL. In this lab environment, we will use OpenSSL on Windows to create the required files before submitting the certificate request to a Certificate Authority. OpenSSL is a widely used tool for working with digital certificates, allowing administrators to generate private keys, certificate requests, and manage different cryptographic operations. The CSR file created during this process contains the certificate information that will be used by the CA to issue the final certificate. In this article, we…

Creating an Internal Certificate Authority is a practical guide that explains how to enable and configure a private CA (Certificate Authority) using the Microsoft Active Directory Certificate Services (AD CS) role. This solution allows organizations to manage their own digital certificates for users, devices, and services. Microsoft AD CS provides a secure and efficient way to issue, manage, and distribute certificates inside an enterprise environment. Certificates generated by an internal CA can be used for different technologies, including SSL/TLS, secure wireless networks, VPN connections, IPsec, smart card authentication, and digital signatures. In this article, we will demonstrate step-by-step how to…

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…
