Lync Concepts Explained

Central Management StoreDeployment ModelConfiguration settings v.s. Policy

Central Management StoreCentral Management Database

Stores Topology, Policies and Configuration data as XML documentsOne single master CMD (xds) per deployment(RTC instance)

ReplicaEach Lync Server maintains a copy (replica xds) of the master CMD (local SQL Express instance RTCLOCAL)Continues to function without access to the master CMD

Central Management ServiceRuns on one Front-End pool per deploymentReplicates changes of policies/configuration toall topology nodes (including Edge via HTTPS)

Deployment ModelGlobal deployment is a collection of SitesSites are made of Pools or ServicesPools host users & services (such as IM/Presence, conferencing, VoIP)Policy Resolution Order: User > Pool > Site > Global

Pools

Sites

Global Microsoft

Zurich

Wallisellen Enge

Redmond

Bellevue

Configuration Settings vs. PoliciesConfiguration Settings

Refer to data or information that Lync Server depends on to operate and function properly in the environmentStored in the Central Management Store (CMS)Applied at the global, site or service scopeAll services or computers are subjected to the same settings without exception.For example, each and every Address Book server in a pool (service scope) must synchronize with Active Directory at the same defined frequency.

Configuration Settings vs. PoliciesPolicies

Deployed to manage behaviors and privileges associated with Cs-enabled usersA policy can be applied at the global, site, service or per-user scopeIf a “setting” can be applied to a user, then it is classified as a policy, as configuration settings cannot be applied to individual users by definition.For example, executives in an organization can be exempted from a global conferencing policy that limits the number of participants by having their own “executive policy” at the per-user scopeContinues to function without access to the master CMD

Field NotesCentral Management Store

“Local machine is not present in the local configuration store”
