Plan and Design a Lync Topology


We will discuss the following:
Plan and Design a Lync Topology
Plan Lync Site Topology
Supported Lync Server 2013 Topologies

Lync Server 2013 supports 
  1. Deployment of sites on premises in an organization
  2. Integration of on-premises deployments with Lync Online deployments, which is known as a hybrid deployment.
  3. In a hybrid deployment, some users are homed on-premises and some users are homed online.

A Lync Server 2013 on-premises deployment consists of the following:
Your deployment must include at least one central site (also known as a data center).

Each central site must contain at least one Enterprise Edition Front End pool or one Standard Edition server. 

These consist of the following:

  1. Enterprise Edition Front End pool, which consists of one or more Front End Servers
  2. Separate Back End Server.
 
  • A Front End pool can contain a maximum of twelve Front End Servers.
  • For SIP traffic, we recommend DNS load balancing, but hardware load balancing is also supported. 
  • If you use DNS load balancing for SIP traffic, you still need a hardware load balancer for HTTP traffic.
  • We recommend SQL Server mirroring for high availability of databases. 
  • The back-end database requires a separate instance
  • You can collocate the archiving database, monitoring database, persistent chat database, and persistent chat compliance database with it. 
  • Lync Server 2013 also supports shared cluster for the file shares.

 

  • Standard Edition server includes a collocated SQL Server Express database.
  • Your deployment can also have one or more branch sites associated with a central site.

Important
If you collocate Lync Server databases
We highly recommend assessing all factors that might affect availability and performance.
To verify failover capabilities, we recommend testing all failover scenarios.

Q: Can we have more than one central site?

The Lync Server 2013 Planning Tool

Two key areas of the new Lync 2013 planning tool are:
Planning Tool Itself
and
Planning Tool Reporting
