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.

Examining VM object health

Even if there are no alarms or disk failures in VSAN, you may wish to examine the specific VMs residing on VSAN storage. The VMs and their disks can periodically change distribution as VSAN load-balances. If there is a problem in a disk group, it will likely affect at least one VM as you increase the number of VMs, so examining the VM will give you a high-level view of any activity or issues associated with the VM.

Getting ready…

You should be logged in to the vSphere Web Client as an administrator or a user permitted to view VM configuration details.

How to do it…

  1. In the vSphere Web Client, navigate to Home | Hosts and Clusters | Datacenter | Cluster.
  2. Select the VM you wish to examine. For this example, we will examine the linux-vm02 VM.
  3. Navigate to Manage | VM Storage Policies while the VM is highlighted.

    Tip

    In vSphere 6.0, the path will be Monitor | Policies | Storage

  4. Once you are on the VM Storage Policies tab, you will be presented with a summary of...
