Exchange VMs are hosted on Vmware hosts and the underlying storage is all flash.
Exchange server backups are taken at VMware level (snapshot based) and exchange DB level.
We are considering putting exchange 2016 DB and log drives on thin provisioned disks.
Is there any recommendation from Microsoft in regards to thin provisioning disks at Vmware level and exchange LUNs at storage array level?
And are there any negative effects of doing this?
Scroll down just past halfway, look for the section labelled “Exchange storage requirements”, 2nd bullet. That explains it pretty well–you can use dynamic virtual storage, but only in certain configurations. Overall, it’s best to NOT use thin-provisioned disks, because of Exchange expecting complete access with no delays for volume size changes as the volume is expanded and the format extended.
