Appendix 1 – FindMe in a VCS cluster
When FindMe is used with a VCS cluster, the FindMe option key must be enabled on every VCS peer
in the cluster. The FindMe database is replicated across all peers in the cluster so that FindMe
functionality can be performed on any peer that a call traverses.

OCS Relay
When FindMe is used with OCS Relay, each peer in the cluster registers a portion of the FindMe
users to Microsoft Office Communications Server so that call loading is shared across cluster peers.
(Calls from OCS to VCS are delivered by OCS to the VCS that registered the user.)
users to Microsoft Office Communications Server so that call loading is shared across cluster peers.
(Calls from OCS to VCS are delivered by OCS to the VCS that registered the user.)
OCS Relay algorithmically selects which FindMe user each peer will register. In this way specific
FindMe users will always register to the same VCS peer – making call analysis and debugging easier.
If a cluster peer becomes inaccessible then the remaining peers algorithmically take over the FindMe
entries of the non-accessible peer. When the peer becomes accessible again, the other peers
relinquish the registrations of the FindMe users that belong to this returning peer.
