High Availability for UE-V 2.0

Updated: December 2, 2013

Applies To: User Experience Virtualization 2.0

This topic describes how to configure a highly available environment of Microsoft User Experience Virtualization (UE-V) 2.0.

Considerations for High Availability for UE-V

The UE-V settings storage location and settings template catalog support storing user data on any writable share. To ensure high availability, certain additional criteria must be met:

  • The storage volume must be formatted with an NTFS file system.

  • The share can use Distributed File System (DFS) replication, but Distributed File System Replication (DFSR) is specifically not supported. For detailed information, see Microsoft’s Support Statement Around Replicated User Profile Data. Distributed File System Namespaces (DFSN) are supported.

  • Because SYSVOL uses DFSR for replication, it is not possible to use SYSVOL for UE-V data file replication for the reasons that are listed in the article about DFSN.

  • The share permissions and NTFS access control lists (ACLs) must be configured as specified in Deploying the Settings Storage Location for UE-V 2.0.

  • High availability can be facilitated through a combination of file server clustering in conjunction with the UE-V Agent to provide access to copies of user state data in the event of communications failures.

  • Both the settings storage path data (user data) and settings template catalog templates can be stored on clustered shares, on DFSN shares, or on both.
