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.

Examining VSAN datastore health


Within VSAN, datastore health is the key to ensuring production continues without any problems. The most important aspect of overall datastore health involves free capacity

It is recommended that the VSAN datastore contain 20 percent free space to enable ideal placement decisions and effective rebalancing of storage objects.

Getting ready

  • Your VSAN should be deployed and functional as per Chapter 2, Initial Configuration and Validation of Your VSAN Cluster.

  • You should be logged in to the vSphere Web Client as an administrator or as a user with view datastore information

How to do it…

  1. From the vSphere Web Client, navigate to Home | Storage | VSAN Datastore.

  2. Click on the Summary tab.

  3. Examine the capacity and number of connected hosts. You should find that the capacity is consistent with the aggregated size of your disk groups, and that the correct number of hosts is connected to the datastore.

Note

If the capacity is inconsistent with the number of capacity-tier disks...
