On-prem Site Recovery Process/Config/Target (OVF) Server acting thick provisioned in vmware

Hello, we have many clients setup using azure site recovery. Most of them we deploy the on-prem config server from the Microsoft OVF. We have seen where the drives in VMware will act as thick provisioned for one of the 600 GB drives and are trying to understand why. Any input would be greatly appreciated, thank you.

@TylerSaville-5293 Thank you for posting your question here!

From the description provided I understand that you are setting up Azure site recovery and notice that one of the server/drive is acting as thick provisioned in VMware.

Its may be because of the options selected as shown in the picture.

We cannot have it thick provisioned in many cases so we try to avoid that and use thin provision. I haven't really seen any performance issues. I am curious as to why when I set it to thin it will act as thick and eat up the storage sometimes (600 GB).

It is quite strange as to why is that getting changed from thin to thick. As recommendation go with thick and see if that makes any difference. You can see it in VMware logs as to which user is triggering this change.
