There's a new article posted by Richard Schwendiman about High Availability and Disaster Recovery with Lync Server 2013 Persistent Chat: Lync 2013 Persistent Chat HA\DR Deep Dive Pt. 1
As everyone knows by now, with the release of Lync Server 2013 we introduced much improved chat functionality, named Persistent Chat (pChat). Not only is it much improved, but it is also an actual role within the topology (no longer standalone application). One thing that I get questioned about a lot regarding pChat is High Availability and Disaster Recovery (HA-DR). Hopefully with this two part article I can help answer some of those questions.
