VMware Virtual SAN Cookbook

Overview of this book

The perfect guide to successful VMware Virtual SAN implementation and operations, with recipes to guide you through the process About This Book Design a Virtual SAN infrastructure from selecting hardware to full capacity. Deploy and manage a software-defined storage solution with VMware Virtual SAN Prepare for architectural and scale changes as your enterprise grows and develops Who This Book Is For If you are an administrator of a VMware vSphere infrastructure and want to simplify storage delivery by integrating storage into vSphere, this book is for you. No extensive storage background is needed as VMware Virtual SAN integrates into the existing vSphere solutions with which you are already familiar. What You Will Learn Prepare your infrastructure for VMware Virtual SAN Plan and build infrastructure solutions to suit your needs Implement VMware Virtual SAN Exploit the power of policy-based management Increase or decrease the scale of your Virtual SAN as needs change Monitor your Virtual SAN infrastructure effectively Respond to and troubleshoot problems In Detail 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. Style and approach A practical guide to implementing VMware Virtual SAN filled with recipes, tips, and detailed explanations.

Collecting other diagnostic information


If vCenter is available, there is additional valuable VSAN information, which if collected, will help with the support process. This information can be obtained from the Ruby vSphere Console and subsequently uploaded to the support ticket.

For a refresher on how to use RVC, please see Chapter 6, Ruby vSphere Console.

Getting ready

You should be able to log in to RVC as a vCenter administrator.

How to do it…

Collecting VSAN support information (Linux RVC)

  1. As we want to collect the support information to upload to the support organization, we will execute the RVC command as a script and redirect the output to a text file that we can subsequently upload.

  2. Run the vsan.support_information command:

    # rvc -c "vsan.support_information /<vCenter>/<datacenter>/computers/<cluster>" -c "quit" <username>@<vCenter> |tee <filename>
    
  3. Enter your password when prompted.

  4. The output will echo to the console and be written with the filename you...
