VMware Virtual SAN Cookbook

By: Jeffrey Taylor

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.

Formulating a problem summary


Unlike the extremely high-level problem description, the problem summary is where we should begin to address more details about the symptoms of the problem and the context surrounding when the problem began, if known.

The same rubric we used for the problem description applies here—we should be clear and concise but also build out more contexts surrounding the problem. It is in the summary that we can provide specific messaging and paint a clearer picture of the issue.

Getting ready

You should have some error messages available/copied, and any applicable conditions that led up to the problem in mind

How to do it …

  1. Determine the full context of the problem.

    • If possible, we should provide a step-by-step story of what led up to the problem.

  2. Collect any error messages.

    • Exact error or notification messaging is very valuable to the troubleshooting process.

  3. Examine the impact to the business.

    • What are the consequences of the problem? Is the business on the line because accounting...
