I was looking at the PVS support site and noticed the release notes for PVS 5 Sp1. I thought this was strange since Provisioning Server 5 Sp1 hasn’t been released yet.
I was looking at the new features of sp1 in the release notes and came across this -
- Difference Disk mode – Allows for the persisting of user data and settings upon reboot.
I had heard that this vdisk feature was coming but I was thinking in the next major release version.
This is a feature I have been asked about several times. I can see this being nice for training classes where students need to ability to reboot and keep their changes.
PVS 5 also changed the vdisk format from a proprietary format to the VHD format. With this new format you can create a thin provisioned vdisk. Thin provisioned vdisks will be great for XenDesktop because in most XenDesktop environments the vdisk I/O is probably 90% – 95% reads.
