Appendix: Updating the Connect and Presence services using Lync Director
To support this capability, the
Microsoft Lync Serveris deployed as one or more pools, based on Standard Edition or Enterprise Edition
Microsoft Lync Server. Users can be homed on only a single pool. Clients can be configured to find their
Lyncpool automatically. However, the DNS records that support this functionality can point to only a single pool. In a multi-pool environment, this "primary" pool will have to redirect users to their correct home pool. This is an overhead on the primary pool. The
LyncDirector is used to offload this redirection functionality. The Director does not home any users itself but instead redirects the user to their correct pool home. The requirement for the Lync Director is therefore for multi-pool environments with high user numbers.
Once the user has been redirected to their correct pool, the
LyncDirector plays no further role in communications between the client and the pool server.
