One of the new cool technologies that VMware have come up with recently is Instant Cloning aka “forking”.

Is was actually talked about way back in 2014 & 2015 but actually saw the light in Horizon 7 as part of just in time technology for VDI VMs.

You can read about it here

as someone who works a lot with VDI and helping our XtremIO customers to leverage the array in the best way they can, I wanted to examine the workload of instant clones VMs on a single XtremIO X-Brick, for this I provisioned 2500 VDI VMs running windows 10 (which in itself is very new to VDI as I only starting to see customers who are starting deploying it now) and office 2016, I didn’t take the easy route as both windows 10 + office 2016 add a significant load on the infrastructure (compute + storage) but since I want to be able to help with future deployments on XtremIO, I chose these two.

In order to generate the workload on the 2500 VMs, I used LoginVSI which is the industry standard to simulate VDI workloads.

The results can see below J
