Knowledge workers must be able to create complex documents and have them persist on the desktop. Power users must be able to install their own applications and have them persist. Depending on the nature and amount of personal data that must be retained, the desktop can be stateful or stateless.
Because power users and knowledge workers, such as accountants, sales managers, marketing research analysts, must be able to create and retain documents and settings, you create dedicated-assignment desktops for them. For knowledge workers who do not need user-installed applications except for temporary use, you can create stateless desktop images and save all their personal data outside of the virtual machine, on a file server or in an application database. For other knowledge workers and for power users, you can create stateful desktop images. Use the following pool settings:
Use dedicated assignment pools so that each knowledge worker or power user logs in to the same desktop every time.
Use the Persona Management feature so that users always have their preferred desktop appearance and application settings, as with Windows user profiles.
Use vStorage thin provisioning so that at first, each desktop uses only as much storage space as the disk needs for its initial operation.
For power users and knowledge workers who must install their own applications, which adds data to the operating system disk, create full virtual machine desktops. Use Mirage to deploy and update applications without overwriting user-installed applications.
If knowledge workers do not require user-installed applications except for temporary use, you can create View Composer linked-clone desktops. The desktop images share the same base image and use less storage space than full virtual machines.
If you use View Composer with vSphere 5.1 or later virtual desktops, enable the space reclamation feature for vCenter Server and for the desktop pool. With the space reclamation feature, stale or deleted data within a guest operating system is automatically reclaimed with a wipe and shrink process.
If you use View Composer linked-clone desktops, implement View Persona Management, roaming profiles, or another profile management solution.
Configure persistent disks so that you can refresh and recompose the linked-clone OS disks while keeping a copy of the user profile on the persistent disks.
