The ephemeral nature of the non-persistent VDI makes it an ideal solution for tasks that require more security. 2 x 2.5 milliseconds = 5 milliseconds. 2. By contrast, non-persistent VDI just seems cheap and inferior. Persistent systems might employ storage technology such as SANs to provide local disk mimicking. Each time users log on to use one of these desktops, they connect to a dynamically selected desktop in a pool of desktops based on a master image. 1. Solution 2 With a non-persistent machine providing persistent user experience, the VM is split into three distinct areas: A non-persistent, consistent and clean OS returning to a snapshot with every restart.
