Introduction to Lync Topologies

Standard Edition server runs all workloads No other server required to additional functionalities All in one box deployment Ideal for proof of concept, pilot, small and medium businesses Functionality: IM, Presence, Voice, Video, Conferencing, Mobility PSTN access with Gateway, Direct SIP or SIP Trunk HA/DR if paired with another SE server AD Standard edition Optional backup Standard edition Pairing

Enterprise Edition Front End pool Back End Server with SQL Server Ideal for large and medium size businesses, regional deployment. Scale up by adding up to 12 FE servers in a pool Collocate Archiving DB, Monitoring DB, PChat DBs on Back End Servers High Availability by FE failover and Mirrored Back End Servers Enterprise edition front end servers SQL AD

User Group 1 User Group 2 Group 1 Group 3 Fabric node Group 2 Fabric node Group 1 Fabric node Group 3 Fabric node Group 3 Fabric node Group 1 Fabric node Group 2 20 Windows Fabric is installed on each Front End Users are provisioned to a pool in Routing Groups Via fabric, three replicas of routing group data are kept updated

Lync Users are automatically mapped to “Groups” Each “Group” is dynamically assigned to 3 Front-end servers within a Pool (a Primary, a Secondary and a Tertiary). When a user logs in, the Primary server will start servicing all of the user’s requests. Changes to the user’s data (such as Contact list changes) will be synchronously replicated to secondary/tertiary as well (3 replicas). If a primary server dies, then this group would fail over to the secondary. (No data loss) Writes to the back-end database occur periodically (not synchronous). When a server dies, all the “Groups” assigned to that server as will failover to different servers (load balancing).

Bob is homed on FE1 (primary) There are 3 copies of this user’s data: 1 primary (FE1), 2 backups (replicas in FE2, FE3) User is signed in to primary User’s activities, data are replicated Pool Back-end Primary goes down User re-signs to one of the backups Replicated data is available on FE2. User

Two pools can be “paired” Backup agent on a Front End writes deltas to a DFS share DFS replicates share content between Lync pools Same as “pool failure”, but applied to geographically distinct pools

Migration Legacy pool SQL Legacy director Legacy edge ProductionPilot Legacy and latest remote access. Legacy and latest federation. AD Latest pool SQL Latest director Latest edge Latest remote access. Install new server or new client first, your choice. Multiple version of Lync server in the same infrastructure. Move users across pool with no users loss of data. Allows seamless migration for users.
