personal vDisk FAQ

Q: How does personal virtual Disk work?

A: Unlike traditional Virtual Desktop Infrastructure (VDI) dedicated pooled deployments, where users lose their customizations and personal applications when the administrator alters the base virtual machine, deployments using personal vDisk retain those changes. This means administrators can easily and centrally manage their base virtual machines while providing users with a customized and personalized desktop experience.

Personal vDisk provides this separation by redirecting all changes made to the user’s virtual machine into a separate disk attached to the user’s virtual machine (the personal vDisk). The content of the personal vDisk is blended at runtime with the content from the base virtual machine to provide a unified experience. In this way, users can still access applications provisioned by their administrator in the base virtual machine.
