VMware Virtual SAN Cookbook

Overview of this book

VMware Virtual SAN is a radically simple, hypervisor-converged storage, designed and optimized for vSphere virtual infrastructure. VMware introduced the software to help customers store more and more virtual machines. As data centers continue to evolve and grow, managing infrastructure becomes more challenging. Traditional storage solutions like monolithic storage arrays and complex management are often ill-suited to the needs of the modern data center. Software-defined storage solutions, like VMware Virtual SAN, integrate the storage side of the infrastructure with the server side, and can simplify management and improve flexibility. This book is a detailed guide which provides you with the knowledge you need to successfully implement and manage VMware VSAN and deployed infrastructures. You will start with an introduction to VSAN and object storage, before moving on to hardware selection, critical to a successful VSAN deployment. Next, you will discover how to prepare your existing infrastructure to support your VSAN deployment and explore Storage policy-Based Management, including policy changes, maintenance, validation, and troubleshooting VSAN. Finally, the book provides recipes to expedite the resolution process and gather all the information required to pursue a rapid resolution.

Understanding and using VSAN Maintenance Mode

As VSAN is fully integrated into your regular vSphere deployment and the VSAN maintenance mode is integrated into the regular vSphere ESXi maintenance mode. When VSAN is active on a host and a cluster, new maintenance mode options are presented to specify how you want to handle data availability when using a maintenance mode in your VSAN-enabled infrastructure. Making maintenance mode decisions consistent with the goal of your operation will help streamline the maintenance process and avoid inadvertent storage-related outages.

Tip

Special VSAN maintenance mode options are not available in the legacy vSphere Client. You must use vSphere Web Client.

For the purposes of this recipe, we will use the Ensure Accessibility option for the VSAN maintenance mode in the examples. For a complete description of all VSAN maintenance mode options, please see the There's More… section in this recipe.
