The VDI Service provides remote access to users from anywhere and from
any device to a full Windows desktop, which is hosted in the Health Science
Center data center.
Type 1 - Random/Non-Persistent – Desktops
are based on a single master image. Users are dynamically connected
to one of the desktops in the pool each time they logon. Changes to
the desktop image are lost upon reboot.
Type 2 - Static/Persistent – Users are
allocated a virtual desktop on first access. Once assigned, users
will always be connected to the same virtual desktop. Changes to
the desktop are stored in a persistent disk and retained between
reboots. Each user requires their own desktop. If high
availability is required, the persistent disk must be stored on
