Part 4 – Disk Groups and vsanDatastore

Hey there! In this post we shall see how a Disk Group is created using the disks attached to the ESXi hosts. Before diving into the creation process, lets gain some understanding  of the Role of Flash Disks, vsanDatastore and the Objects associated with a VM.

Each Flash Disk that is part of the VSAN cluster will either be used for Read Cache or Write Buffer.
