- 6. VDI Provisioning: The Lines Are Blurring • Controls needs to be applied at Access Edge and within the Data Center ToR • Identity, Roles and Mobility pervasive across Campus and DC • Mapping Identity to Physical Desktop Machine and Virtual Desktop Machine • Dynamic roles, policies, and identity need to be consistent Internet “Virtual” John User Traffic User Traffic VDI Session “Physical” John Access Edge Core Network Data Center Data Center Wiring Closet ToR VM Servers 6 © 2012 Extreme Networks, Inc.
