I didn’t know that Microsoft had already invested so much in reducing storage space.

WIM is an interesting format and I was surprised to find it being used for Vista deployments.

Ardence doesn’t have a true SIS/deduplication feature but they do have a shared image model. It seems that the next step is to give it more SIS like abilities for non-shared images.

I think this has been done already at so many levels. For example, Windows Home Server supports it as Single Instance Store:

Network level? What about Citrix WANScaler cache? It maps big data chunks to smaller strings so data across the wire is compressed automatically.

Disk image level? Windows Image Format supports single instance store, and Citrix Provisioning Server (Ardence) allows you to boot several servers from SAN, preventing configuration issues and local disk problems. For VDI, check Citrix Provisioning Server for Desktops.
