VMware Horizon View provides administrators with the ability to automatically provision and manage pools of desktops. As part of the provisioning of desktops, we must consider how we will continue service for the individual users in the event of a host or storage failure. Generally, High Availability requirements fall into two categories for each pool. We can have stateless desktops, where the user information is not stored on the VM between sessions, and stateful desktops, where the user information is stored on the desktop between sessions.
In a stateless configuration, we are not required to store data on the virtual desktops between user sessions. This allows us to use local storage instead of shared storage for our HA strategies, as we can tolerate host failures without the use of shared disk.
We can achieve a stateless desktop configuration using roaming profiles and/or View Persona profiles. This can greatly reduce cost and maintenance requirements...
