For environments that leverage a user persona solution, such as Liquidware Labs ProfileUnity, placing the user personas on a highly available network share is critical to ensure end user data is always available. By using the Distributed File System (DFS) service or Distributed File System Replication (DFS-R) service, a user persona that stores file shares will still be available in the event of a file server failure. In addition, with DFS-R, user personas can be replicated to other servers in the same site or other sites. DFS-R enables a VDI to provide Continuity of Operations (COOP) by ensuring that the file share that contains the user personas has its data replicated offsite.

Microsoft DFS also leverages Active Directory sites to ensure that an end user is retrieving their persona from the nearest server that is participating in the DFS/DFS-R group. In addition, site costing can be used to state the least expensive target selection for the end users that attempt to retrieve...
