VSAN

In today’s blog, we’re diving into the world of storage solutions, specifically comparing VMware’s vSAN Express Storage Architecture (ESA) with traditional storage systems like SAN (Storage Area Network) and NAS (Network Attached Storage). If you’re wondering which storage solution is right for your environment, this post is for you. We’ll explore the key differences in architecture, performance, scalability, cost, management, and use cases to help you make an informed decision. ...

Setting up a vSAN cluster on a single ESXi host without vCenter is simpler than you might think. This guide walks you through a CLI-based method to configure VMware by Broadcom’s vSAN in a standalone environment. Whether you’re testing in a lab or laying the groundwork for a larger cluster, a single node vSAN deployment offers a flexible starting point that scales as your needs grow. What Is a Single Node vSAN? VMware by Broadcom’s vSAN is designed for multi-host clusters managed by vCenter, typically requiring at least two hosts for production resilience. However, with CLI tools, you can establish a vSAN cluster on a single ESXi host. This setup is ideal for experimentation or initiating a cluster, providing a solid base for later expansion with vCenter and additional nodes. ...

In the world of infrastructure as code (IAC), there are many tools to choose from. Two popular options are VMware vRealize Automation (vRA) and Terraform. While both have their strengths, there are compelling reasons to choose vRA over Terraform. End-to-End Automation: vRA automates the entire software-defined data center (SDDC) lifecycle, from provisioning to decommissioning. Terraform is more limited, focusing only on infrastructure provisioning. User Experience: vRA provides a user-friendly interface, making it easier for non-technical users to request and manage infrastructure. Terraform, on the other hand, requires more technical expertise to use effectively. Integration with VMware: vRA integrates with other VMware products, such as vSphere, NSX, and vSAN, allowing for a seamless experience. Terraform can also integrate with VMware, but it requires more manual effort to set up the integration. Enterprise-Grade Security: vRA includes enterprise-grade security features, such as role-based access control and multi-factor authentication. Terraform does not have built-in security features, requiring additional tools or manual effort to secure the environment. Robust Compliance Features: vRA includes compliance features, such as blueprints that enforce specific policies and standards, making it easier to meet regulatory requirements. Terraform does not have built-in compliance features, leaving it up to the user to ensure compliance. Strong Support: vRA has a large, global community of users and is backed by VMware, a well-established company in the tech industry. Terraform is a relatively new tool with a smaller community, making support and resources more limited. In conclusion, vRA offers a complete automation solution for the SDDC, making it a great choice for enterprises that want a user-friendly interface, strong security features, robust compliance features, and strong support. Terraform, while a powerful tool, is better suited for infrastructure provisioning and requires more technical expertise and manual effort to secure and ensure compliance.

While doing maintenance on my vSAN cluster recently i had the need to disable the vCLS in order to fully shut down the cluster. Doing some reasearch i found kb article 80472 that talk about temporarily disabling the service in order to perform maintenance. The steps are fairly easy First we need to get the Cluster id from vSphere. To do so all we need to do is select the cluster and look at the url. For example ...

I have the need to completely shut down some of my vSAN clusters for various clusters and ive been having a hard time finding the proper procedure. As of 2/16/2021 VMware released guidance here Here are the steps i took to do it on my end. If you have the vCLS service enabled follow my other instructions here prior to starting the rest of this guide. Disable cluster member updates from vCenter on each ESXi host in the cluster by running ...
