Microsoft Lync 2013 offers a number of DR and failover features. How does it differ from the 2010 version?
Microsoft's Lync Server 2013 is currently in "preview" mode. The following are differences between the 2010 and 2013 versions for disaster recovery.
- As in Lync 2010, the main high availability scheme for Lync 2013 Preview is based on server redundancy via pooling. If a server performing a specific function fails, the other servers in the pool performing the same function(s) take the load off that server. This applies to Front End Servers, Edge Servers, Mediation Servers, and Directors.
- Another disaster recovery advancement Lync 2013 Preview offers over Lync 2010 is support for geographical dispersion of servers into two (or more) data centers to provide continuation of service should an entire server pool or site (e.g., data center) fail.
- Lync 2013 Preview adds disaster recovery support for Lync Server Response Group service and Lync Server Call Park service.
- Another advance over 2010 is that Lync 2013 Preview includes Back End Server high availability. This is accomplished by configuring a topology deploying two Back End Servers for a Front End pool, and setting up synchronous SQL mirroring for all the Lync databases running on the Back-End Servers.
Note: The above items are considered preliminary.
