VDI can be deployed in two essential modes: persistent or non-persistent.Persistent VDIWith persistent VDI, the user is assigned a permanently reserved VDI resource. The same VDI instance is available to him or her at log-on. This way, the user can establish personal settings like shortcuts, screensavers, and stored passwords. They can also save files to their personal, permanent desktops. The advantages of persistent VDI include the ability to customise the desktop for the user’s individual preferences. The personalised nature of persistent VDI also lends itself to greater usability. The user is more familiar with the desktop, so it’s easier to use. Desktop management also becomes easier, as the persistent desktop can be administered in the same way as physical desktops.Non-persistent VDIIn contrast, when VDI is set up as non-persistent, the user gets a fresh VDI image each time he or she logs on. The benefits of non-persistent VDI are that it’s easier to manage and requires less storage.
