An interesting question on behalf...

> With regard to the release notes, do you understand this restriction?
>
> 1.1.1. VSI OpenVMS Does Not Support Thin-Provisioned Volumes on
> Any Architecture
>
> I understand "Thin provisoning" to be that when an OpenVMS tries to
> define a disk with a certain size, that the virtualizing platform does
> not initially reserve all the space defined, but only for the blocks
> that are occupied. When the space grows the virtualization SW will map
> more physical storage.
>
> With "thick provisioning" all the physical space is pre-allocated,
> whether an Operating System uses it or not.
>
> What does an Operating System have to do to be able to support "Thin
> provisioning"?
>
> Does a virtualizing environment VMware/KVM not act like an intelligent
> storage solution?
> ie. it is all transparent for the Operating System?
