Cody’s article on UNMAP changes for vSphere 6 got me thinking about how this plays out in the VDI context. I’ll explore a bit desktops deployed both as linked clones with and without se-sparse disks as well as full desktops with thin provisioned disks. Before we get started I’m first going to turn on the advanced option VMFS3.EnableBlockDelete for all hosts in my “PROD” cluster using PowerCLI. This will be required for the full desktops with thin provisioned disks. Desktops with the se-sparse disks will be UNMAP’d through VMware View.
