Dedicated pools are View desktops provisioned using thin or thick provisioning. Dedicated pools are typically used for Stateful Desktop deployments. Each desktop can be provisioned with a dedicated persistent disk used for storing the user Profile and data. Once assigned, a desktop that user will always log into the same desktop ensuring that their profile is kept constant.
During OS refresh, balances, or recomposes, the OS disk is reverted back to the base image.
Dedicated pools with persistent disks offer simplicity for managing desktops as minimal profile management takes place. It is all managed by the View composer/View connection server. It also ensures that applications that store profile data will almost always be able to retrieve the profile data on the next login. This means that the administrator doesn't need to track down applications that incorrectly store data outside the roaming profile folder.
