Introduction

As with any production system, VSAN will require periodic maintenance. Drivers and system firmware will need to be updated, new releases of vSphere will ship, and various configuration changes or hardware updates will need to be performed. You may want to expand or contract the amount of storage available to VSAN, add or subtract nodes, or make various other modifications to your infrastructure.
