About clusters
A Cisco VCS can be part of a cluster of up to six Cisco VCSs. Each Cisco VCS in the cluster is a peer
of every other Cisco VCS in the cluster. When creating a cluster, you define a cluster name and
nominate one peer as the master from which all relevant configuration is replicated to the other peers in
the cluster. Clusters are used to:

nominate one peer as the master from which all relevant configuration is replicated to the other peers in
the cluster. Clusters are used to:
n
increase the capacity of your Cisco VCS deployment compared with a single Cisco VCS
n
provide redundancy in the rare case that a Cisco VCS becomes unavailable (for example, due to a
network or power outage)
network or power outage)
Peers share information with each other about their use of bandwidth, registrations, and user
accounts. This allows the cluster to act as one large Cisco VCS Local Zone as shown in the example
