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.

Enabling SSH on the ESXi hosts (if applicable)

Note

If you are running vSphere 6.0, please skip this section and refer to the Tagging disks as SSDs in vSphere 6.0 recipe in Chapter 9, VSAN 6.0, if you need to tag your disks as SSDs.

If you need to tag disks as SSD devices, you will need CLI access to the ESXi host. If we are using RAID-0 storage controllers, ESXi will detect the SSDs as normal magnetic drives due to the way RAID-0 controllers present storage to the operating system. The tagging process will only be applicable to SSDs that were not correctly identified as such by default. The SSD-tagging process requires several commands in vSphere 5.5 and it is easiest to perform these steps via a remote console (SSH).

Note

If SSH is already enabled on your hosts or if you will not need to tag SSDs, please skip this recipe.

Getting ready

You should be logged in to the vSphere Web Client as an administrator or user, authorized to alter host-level security profile settings.
