17.8. Session Directory

The Windows connector supports server session reconnection based on load-balancing information and the Session Directory, a database that keeps track of which users are running which sessions on which Windows system. Session Directory functionality enables Windows connector users to reconnect automatically to the right Windows session.

Both IP address-based and token-based reconnection are supported. However, token-based redirection requires the use of a hardware-based load balancer for Windows systems configured as a server farm. The capacity to use server farms and load balancing enables Windows systems to accommodate a larger number of Sun Ray users and clients.


To participate in a Session Directory-enabled server farm, the Windows systems must run Windows Server 2003 R2, Windows Server 2008 R2, or Windows Server 2012. Session Directory is an optional component that can be configured to use Microsoft proprietary or third-party load balancing products.

Terminal services session load balancing is handled transparently by the Windows Terminal Server.

For details about setting up and managing a Session Directory and load balancing, refer to the Microsoft documentation.
